The Definitive Smashburger Gluten-Free Menu Guide 2025
Building atop craveable smashed hamburgers on artisan bread, our Smashburger gluten-free menu guide will show you the importance of lettuce wraps and GF buns.
Boutique, artisanal hamburgers are in vogue now, which is actually superb news for celiacs like me, because unlike most fast-food restaurants and casual burger shops, they could, for once, be able to craft a perfectly celiac-safe burger. 🍔🍟
From swapping out wheat-battered and breaded patties to grilled proteins, or removing the odious wheat buns for gluten-free rolls and lettuce wraps, we celiacs stand a better chance of being able to enjoy gluten-friendly burgers now. 🥪🥬
Perhaps one of the best examples of how far things have come is Smashburger, well-known for its mouthwatering menu centered around smashed beef patties, artisanal buns, chicken sandwiches, and deliciously seasoned SmashFries. ✋🚫🌾
Sure, it’s still a bit of a minefield to navigate if you’re a celiac or if you have a severe gluten intolerance or sensitivity, but compared to a lot of the fast-food places that I’ve been to, it’s certainly a lot more tolerable, that’s for sure. 🍞🍗🔥
All you have to do is avoid their wheat-based buns, breaded coatings, or sauces that can contain gluten, as well as the risk of cross-contamination, but worry not, our Smashburger gluten-free guide is here to help walk you through it, step by step!

Disclaimer
With that being said, however, despite my praise for Smashburger and their relatively celiac-friendly menus and practices, it’s still worth bearing in mind that Smashburger doesn’t operate any certified, dedicated gluten-free kitchen spaces. 🔪🍴
In other words, cross-contamination is a very real hazard that you have to be wary of, as most of their menu contains wheat, and Smashburger’s kitchens usually handle wheat-free items alongside wheat-filled baked goods and battered or fried dishes.
As such, even if you order something from Smashburger’s menu that’s technically naturally free of wheat, there’s no guarantee that it won’t come into contact with wheat and gluten through cross-contamination with nearby items. 👉🚫🌾
This doesn’t just include wheat, either, as it would also include other glutenous components like malt, barley, rye, and/or oats, which could cross-contaminate even the safest items on their menu, owing to Smashburger’s heavy reliance on shared kitchens.
Personally, I’d consider treating even the safest, most wheat-free and “gluten-friendly” item on Smashburger’s menu more like “gluten-sensitive” instead of a guarantee of being 100% certified “gluten-free”, just to be extra safe. ✍📝💯
Additionally, as with most restaurants, Smashburger doesn’t test its menu items to meet the FDA’s pretty strict <20 ppm threshold for a particular food or drink item to be labeled and certified as officially gluten-free. 😷🧪
With all of this in mind, if you’re planning to dine out at Smashburger, remember to inform the staff about your celiac disease and ask them to take extra precautions like using fresh gloves, clean utensils, and a wiped-down prep area.
Smashburger Allergen Policy (Gluten-Free)
But hey, on the bright side, at least Smashburger makes it quite easy for you to filter their menu for all the items you can’t eat and need to avoid, while helping you find other items that could safely accommodate your diet.
To start, you have to head over to the official Smashburger website, and from there, click or tap on that giant text on the top-most navigation bar that says “Nutrition”, and doing so will open a new tab on your browser.
This new tab is where you’ll load up Smashburger’s interactive allergen and nutritional menu, and once you select the nearest Smashburger location on the little search bar, you’re then prompted to set your dietary preferences.
- Here, you can set your nutritional goals, such as the maximum amount of calories that you want to order at a time, various lifestyle options, such as conforming to a vegetarian diet, and you’re also able to set your allergies or dietary restrictions.
- In the latter part, all you need to do is flick whichever allergen you’d like to avoid, which will include all the major allergens, such as milk, soy, eggs, peanuts, shellfish, and more, and for celiacs like me, make sure you toggle “Gluten” and “Wheat”.
- Once you’re done setting your preferences, click on “Save & Go!”, and this will filter out the Smashburger menu, which, in my case, highlighted all the items that are either “suitable” or “unsuitable” on whether they included wheat and gluten.
Furthermore, if you click on any of the menu items that appear on this interactive widget, it loads up even more detailed information that you can take a glance at, which may come in handy if you’re curious about what’s inside your food, including:
- Nutrition Information – This section is basically an in-depth breakdown of the nutritional data for this specific menu item, and it tells you how many calories, cholesterol, carbs, fat, protein, and more are in each menu item, which is neat if you’re conscious about your diet.
- Combined Ingredients – Below that, you’ll find another section that gives you the complete list of ingredients for this particular item, which also updates if you change the selections on the right-hand side, and it’s a neat alternative method of filtering out their huge menu.
- Selections – Speaking of, the right-hand side is where you can customize and modify this specific menu item, like removing toppings, choosing different sauces, and so on, and it’ll also highlight red flags to avoid depending on which allergens you picked to avoid earlier.
Smashburgers
Smashburger’s smashed patties are built around artisan buns, and while this normally sets off alarm bells, you can modify a Smashburger and swap the wheat bun for a lettuce wrap, going bun-less, or with a Udi’s gluten-free roll instead! 🍔👉🚫🌾

To figure out how you can make these Smashburgers safe, let’s see how they’re made:
Double Colorado Smash: Two smashed beef patties with Colorado-style toppings served on a bun by default. You can request a lettuce wrap, no bun, or a verified Udi’s gluten-free roll to remove the ingredient-level wheat, but remember to ask the staff to build it on a clean surface, and confirm no shared toasting.
Colorado Smash: Single-patty Colorado-style burger on a bun. Swap to a lettuce wrap, go bunless, or request a packaged gluten-free roll to eliminate the bread ingredient, though you should still verify sauces and toppings for hidden wheat and ask for separate plating to limit cross-contact.
Double Smoked Brisket Bacon Smash: Double patties with smoked brisket and bacon. Although bun swaps may be offered at some locations, the smoked brisket component is commonly sauced or finished on shared equipment, so request ingredient confirmation and isolated prep if attempting to make this safe.
Smoked Brisket Bacon Smash: This Smashburger comes with a toasted brioche bun by default that cannot be changed. Because the bun is required and toasted on-site, this item contains wheat by ingredient and is unsafe for celiac diners.
Double All-American Smash: Two classic smashed patties on a bun by default. You can ask for a lettuce wrap, no bun, or a Udi’s gluten-free roll, but always confirm the roll brand and packaging and whether the toaster is shared before accepting the swap.
All-American Smash: Classic single-patty All-American on a bun. Request no bun, a lettuce wrap, or a verified gluten-free roll to remove the ingredient wheat, but you should still insist on clean prep, fresh gloves, and separate plating to reduce trace contamination.
Double Deluxe Smash: Two patties with deluxe toppings on a bun. It can be modified by swapping the bun for lettuce, no bun, or a Udi’s gluten-free roll, but check whether any deluxe sauces contain wheat thickeners, and ask the staff to confirm separate assembly.
Deluxe Smash: Single-patty deluxe on a bun. Switching to a lettuce wrap, no bun, or a packaged Udi’s gluten-free roll removes the bread ingredient, but request separate prep and confirm sauce ingredients to avoid hidden wheat.
Double Classic Smash: Double classic patties on a bun. Order it bunless, as a lettuce wrap, or on a verified gluten-free roll to avoid the bun, though verify that the patties and the toppings aren’t handled near breaded items and request isolated preparation.
Classic Smash: Single classic patty on a bun. Choose a lettuce wrap, no bun, or a Udi’s gluten-free roll to remove wheat by ingredient, and always ask staff to prepare it on a clean surface with fresh gloves and to avoid toasting the substitute roll on shared equipment.
Double Bacon Stack Smash: Two patties stacked with bacon on a bun. Swap the bun or go bunless to eliminate the bread ingredient, but make sure to confirm that the bacon isn’t glazed with a wheat-containing sauce and request separate plating to further minimize any risk of cross-contamination.
Bacon Stack Smash: Single-patty bacon stack on a bun. Remove the bun (or use a verified gluten-free roll) and ask for isolated assembly, though check that any bacon finishes or smokes for hidden thickeners that could contain wheat.
Double Spicy Jalapeño Smash: Two spicy patties with jalapeño toppings on a bun. Bun swaps (lettuce wrap, no bun, or a Udi’s gluten-free roll) can remove ingredient wheat, but double-check spicy sauces for wheat-based thickeners and ask for separate saucing tools to avoid cross-contact.
Spicy Jalapeño Smash: Single spicy-patty variant. Swap the bun or go bunless to remove the bread ingredient, and remember to confirm that the sauces and the pickled toppings are wheat-free and request that the burger be assembled on a clean prep area.
Black Bean Smash: Black bean patty served on a bun by default. It could be modified, either with a lettuce wrap, no bun, or a Udi’s gluten-free roll, but confirm the patty’s ingredient list, given that some plant-based patties use wheat or breadcrumbs as binders. If the patty itself is wheat-free, a bun swap can make this safe by ingredient.
Double BBQ Bacon Smash: Double patties with BBQ and bacon on a bun. Swap the bun for a lettuce wrap, no bun, or a packaged gluten-free roll to remove the ingredient-level wheat, and verify that the BBQ sauce is wheat-free, and ensure separate handling to reduce cross-contact.
BBQ Bacon Smash: Single-patty BBQ bacon option on a bun. Modify the bread by swapping it for a lettuce wrap, going bun-less, or replacing it with a Udi’s gluten-free roll, like the above, and confirm the sauce ingredients and prep procedures to lower cross-contact risks.
Double Truffle Mushroom Smash: Two patties with truffle mushrooms on a bun. Request a bun swap or no bun to eliminate the bread ingredient, and confirm mushroom sauces or sauté bases don’t include flour-based thickeners before eating.
Truffle Mushroom Smash: Single truffle-and-mushroom smash on a bun. Swap to the lettuce wrap, the no-bun option, or a verified gluten-free roll and check the sauté/sauce for wheat thickeners, while also asking for separate utensils and plating to reduce trace exposure.
Veggie Smash: Vegetarian-style patty that contains wheat and gluten components by ingredient. Because the patty itself includes wheat, this Smashburger is unsafe for celiac diners even if you remove the bun or request substitutions.
With only a couple of exceptions, most of Smashburger’s namesake Smashburgers could be made celiac-safe by simply swapping out the default wheat-based artisan bun, but bear in mind that this alone doesn’t negate the cross-contact risk. 🥪🍖🧀
All-Angus Big Dogs & Chicken
Alternatively, if you’re looking for something a bit different than smashed-up burgers, you could check out Smashburger’s hot dogs and chicken sandwiches, and while most of these are unsafe for celiacs, you do have a few options. 🍔🍗🔥🌶️
❌ Colorado Big Dog
❌ Cowboy Big Dog
❌ Americana Big Dog
❌ Bacon Cheese Big Dog
❌ Chili Cheese Big Dog
⚠️ Crispy Chicken Sandwich
⚠️ Scorchin’ Hot Crispy Chicken Sandwich
⚠️ Chicken Smash Burger
⚠️ Double Chicken Smash Burger
❌ Chicken Tenders
❌ Scorchin’ Hot Chicken Tenders
For comparison, let’s take a closer look at each of these hot dogs and chicken sandwiches:
Colorado Big Dog: Signature hot dog served on a toasted bun with Colorado-style toppings. The bun and any toasted assembly mean this item contains wheat by ingredient and is unsafe for celiac diners. Plus, the shared grill and toaster use increases cross-contact risk.
Cowboy Big Dog: Loaded hot dog with cowboy-style toppings on a wheat bun. Because the bun and some toppings are prepared on shared surfaces, this item is an ingredient-level gluten risk and should be avoided if you require strict gluten-free handling.
Americana Big Dog: Classic hot dog on a wheat roll with traditional toppings. The roll contains wheat, and the hot dog itself is assembled on shared prep areas, creating both ingredient and cross-contact hazards for gluten-sensitive diners.
Bacon Cheese Big Dog: Hot dog with bacon and melted cheese on a bun. The bun is wheat-based, and the assembly process uses shared toasters and utensils, so this is another menu item that’s unsafe for celiac diners.
Chili Cheese Big Dog: Hot dog topped with chili and cheese on a wheat bun. The bun and potential chili thickeners and handling could introduce a lot of wheat exposure, making this an ingredient-level gluten risk and unsafe for strict gluten avoidance.
Crispy Chicken Sandwich: Breaded, crispy chicken filet served on a bun by default. You can request a lettuce wrap, no bun, or a verified gluten-free roll, and remember to omit the crispy patty and order the sandwich without protein. However, shared fryers, toasters, and assembly surfaces create cross-contact risk even after swaps.
Scorchin’ Hot Crispy Chicken Sandwich: Spicy breaded chicken on a wheat roll. It could be modified by requesting a lettuce wrap, no bun, or a packaged gluten-free roll and by omitting the crispy patty, yet the breading and the shared fryers and toasters mean extra caution is needed when ordering.
Chicken Smash Burger: Chicken-based smash served on a bun. Swap to a lettuce wrap, no bun, or a verified gluten-free roll to remove the ingredient-level wheat, but confirm sauces and separate prep to reduce cross-contact from nearby breaded items.
Double Chicken Smash Burger: Double chicken patties on a bun by default. Request a bunless option, lettuce wrap, or packaged gluten-free roll to eliminate the bread ingredient, and ask staff to prepare it on a clean surface with fresh gloves to lower contamination risk.
Chicken Tenders: Breaded chicken strips fried in shared oil. These are an ingredient-level wheat source because of the breading and are cooked in shared fryers and handled with common utensils, which is unsafe for celiac diners.
Scorchin’ Hot Chicken Tenders: Spicy breaded tenders with wheat-containing coating. The batter and shared fryer and utensil use create both ingredient-level gluten and high cross-contact risk, so avoid if you must follow a strict gluten-free diet.
Alas, most of Smashburger’s Big Dogs and breaded chicken contain wheat, but at least a few of their chicken-smash sandwiches could be modified to be safe by removing the wheat bun or going bun-less, or even omitting the breaded patty. 🌭🐔
Salads, Sides & Kids Meals
For something a bit lighter, maybe you should check out Smashburger’s salads, sides, and the kids’ menu, with a plethora of salads, fries, tots, and snacky sides. Best of all, most of them are safe, though be wary of cross-contamination. 🥗🧀🌶️🍔
❌ Crispy Chicken Bacon Ranch Salad
⚠️ Smash Fries
⚠️ Smash Tots
⚠️ French Fries
⚠️ Tots
⚠️ Sweet Potato Waffle Fries
⚠️ Scorchin’ Hot Fries
⚠️ Scorchin’ Hot Tots
⚠️ Crispy Brussels Sprouts
✅ Cup Of Cheddar Cheese Sauce
✅ Cup Of Homestyle Chili
⚠️ Kid’s Smashburger with Fries
⚠️ Kid’s Smash Cheeseburger with Fries
❌ Kid’s Tenders
Just to be extra sure, let’s take a closer look at each one and see what they’re made of:
Crispy Chicken Bacon Ranch Salad: Salad topped with breaded crispy chicken and bacon. The breaded chicken contains wheat by ingredient, and the salad is assembled near other wheat items, so this is unsafe for celiac diners and should be avoided.
Smash Fries: Smashburger’s seasoned fries. Potatoes are gluten-free by ingredient, but many locations use shared fryers or shared baskets, so confirm whether the fryer oil is dedicated, and request fresh tongs to reduce cross-contact risk.
Smash Tots: Seasoned tater tots offered as a side. Tots are typically wheat-free by recipe, yet they’re often fried in the same oil as breaded items, though ask if the fryer is shared and request separate serving utensils.
French Fries: Classic cut fries. The ingredient-level risk is low, but shared fryers are the main cross-contact vector, so verify fryer practices and ask staff for confirmation before ordering if you have celiac disease, just to be safe.
Tots: Plain tater tots (non-seasoned). The same guidance applies to the other fried potato items here, too. The ingredient-level gluten risk is low, but shared fryers and ladles can cause contamination, so request information on fryer dedication and fresh tongs.
Sweet Potato Waffle Fries: Sweet potato waffle-cut fries. By recipe and ingredient, they’re generally wheat-free, but fryer-sharing is the concern. Ask whether these are cooked in a dedicated fryer and request separate handling.
Scorchin’ Hot Fries: Spicy seasoned fries that may share fry oil with breaded items. The spice rub itself rarely contains wheat, yet fryer and basket sharing raise cross-contact risk, so confirm fryer policy before ordering.
Scorchin’ Hot Tots: Spicy tater tots variant. The ingredient-level wheat risk is low, but the usual shared-fryer issue applies, so remember to request confirmation that fryer oil is not shared with breaded products and ask for clean utensils.
Crispy Brussels Sprouts: Pan-finished or roasted and brined sprouts offered as a side. If they are battered or finished with a sauce that uses flour thickeners, they may contain wheat. Otherwise, they’re often lower-risk, but verify preparation method and ask for separate prep if unsure.
Cup of Cheddar Cheese Sauce: Individual portion of cheese sauce. Cheese sauce is commonly wheat-free by recipe, but it can be cross-contaminated via shared ladles or refillable containers, so make sure you request a freshly poured cup or sealed portion to reduce contamination risk.
Cup of Homestyle Chili: Small serving of chili. Chili recipes sometimes use thickeners or pre-mixed ingredients that contain wheat, so you should ask the staff whether the chili contains wheat-containing thickeners and request a fresh scoop and clean ladle if ordering.
Kid’s Smashburger with Fries: Child-sized smashburger served on a bun by default. This can be modified–lettuce wrap, no bun, or a packaged gluten-free roll–but confirm the brand of the bun itself, and whether buns are toasted on shared equipment, and ask for separate assembly to reduce cross-contact.
Kid’s Smash Cheeseburger with Fries: Kid’s cheeseburger with fries. Swap the bun for a lettuce wrap, go bunless, or request a certified packaged gluten-free roll to remove the ingredient-level wheat, though you should still insist on clean prep and separate plating to lower trace exposure.
Kid’s Tenders: Breaded chicken tenders in the kids’ menu. These contain wheat in the breading and are fried in shared oil and handled with common utensils, and they’re unsafe for celiac diners and should be avoided.
Only a couple of these are downright hazardous, but while most fries, tots, and small sides are wheat-free by ingredient, they’re at risk from shared fryers, ladles, and prep areas, so you should approach them with an abundance of caution. 🍟🥔🍠
Hand-Spun Shakes & Beverages
Apart from their drinks, which, like with most restaurants, tend to be quite safe as far as gluten is concerned, Smashburger’s hand-spun shakes are mouthwatering, though they’re often blended and prepped with shared equipment. 🥛🍫🍓🍪
✅ Peanut Butter Shake
❌ Oreo Cookies & Cream Shake
✅ Chocolate Shake
✅ Vanilla Shake
✅ Strawberry Shake
✅ Salted Caramel Shake
✅ Diet Coke
✅ Coca-Cola
✅ Sprite
✅ Kids Honest Organic Apple Juice
✅ Kids Horizon Organic Milk
✅ Kids Horizon Organic Chocolate Milk
To make sure that we got this right, let’s check out what these savory drinks are made of:
Peanut Butter Shake: Creamy shake made with ice cream and peanut butter. As far as the ingredients are concerned, it contains no wheat, but shared blenders and topping stations can carry cookie crumbs, so ask the staff to rinse the blender thoroughly or use a clean blender container before making your shake.
Oreo Cookies & Cream Shake: Made with crushed Oreo cookies, which contain wheat. This is an ingredient-level gluten source, and it’s unsafe for people with celiac disease or severe gluten sensitivity and intolerance.
Chocolate Shake: Chocolate ice cream blended with milk. This is usually wheat-free by recipe, though cross-contamination is possible via shared blenders or scoops, so request a freshly rinsed blender and confirm no cookie or bakery mix-ins are added.
Vanilla Shake: Classic vanilla ice cream blended to order. Vanilla shakes are generally wheat-free by ingredient, though you should still ask staff to use a clean blender jar and to avoid any cookie and cake mix-ins to keep trace contamination risk low.
Strawberry Shake: Fruit or strawberry-flavored shake blended with ice cream. By recipe and ingredient, this is typically free of wheat, but shared blending equipment and powdered toppings can introduce crumbs, so request a cleaned blender and separate utensils.
Salted Caramel Shake: Caramel-flavored shake that is normally wheat-free by ingredient. Just make sure to verify that any caramel sauces or swirls don’t include cookie pieces, and ask for a freshly cleaned blender to reduce cross-contact from bakery items.
Diet Coke / Coca-Cola / Sprite: Fountain or bottled sodas contain no wheat ingredients. For the lowest risk possible, you ought to prefer factory-sealed cans or bottles, or if it’s fountain-dispensed, ask the staff to wipe the nozzle before pouring to minimize remote cross-contact.
Kids Honest Organic Apple Juice: Factory-sealed juice box is naturally gluten-free and very low risk. Sealed packaging is the safest choice for celiac diners, as it eliminates on-site cross-contact concerns.
Kids Horizon Organic Milk: Pasteurized milk in single-serve containers is gluten-free by ingredient and very low risk. Choose sealed cartons for the safest option, especially for highly sensitive diners.
Kids Horizon Organic Chocolate Milk: Chocolate milk in single-serve packaging is usually wheat-free by ingredient. Confirm there are no cookie mix-ins or flavored syrups added, and prefer sealed cartons for minimal cross-contact risk.
As we can see, at least one of these hand-spun shakes contains wheat mix-ins, which is also a good reminder to be wary of cross-contamination, mainly with picking up crumbs, shared blenders, as well as contaminated topping stations. 🥤🧃🍎🍏
To Sum Up
On the whole, I’m actually pleasantly surprised by how committed Smashburger is when it comes to catering to folks with all kinds of lifestyle choices and dietary restrictions, which is always a huge relief when you’re dining out as a celiac. 🍟🍗
Almost all of their signature, namesake smashburgers and sandwiches could be made safe with simple substitutions, by replacing the wheat artisan bun with a lettuce wrap, bun-less, or instead opting for a Udi’s gluten-free roll. 🍔🥪👉🚫🌾
Of course, caution is still advised because their use of a shared kitchen environment means that there’s never a guarantee that a particular menu item is “gluten-free”, but at least it’ll make them “gluten-sensitive”, which is nevertheless a big upgrade.
Plus, you could complement your burgers with a decent selection of relatively safe sides, in addition to a savory hand-spun milkshake. Overall, then, I’m quite impressed, and I’d totally recommend Smashburger to any burger-starved celiac! 👍👍👍

Frequently Asked Questions
While working on this Smashburger gluten-free guide, I came across a few interesting questions floating around social media, so I thought I’d try and answer them here:
Is Smashburger gluten-free?
No, not entirely. Smashburger isn’t a certified gluten-free restaurant, and many of its staple menu items use wheat-based buns, breaded coatings, and sauces that may contain gluten. However, you can still modify their signature smashburgers and sandwiches to make them a lot safer for strict gluten-free diets and celiacs.
What are the safest choices at Smashburger for someone avoiding gluten?
Safer picks are factory-sealed drinks and simple, plain sides that aren’t fried in shared oil. You could also order many burgers bunless or as a lettuce wrap, which removes the default wheat artisan bun, or even have the option to swap in a Udi’s gluten-free roll, though the risk of cross-contamination still applies.
Can I make a Smashburger order gluten-free by modifying it?
For most of their burgers, yes. Many smashburgers and sandwiches can be modified by requesting a lettuce wrap, no bun, or a packaged gluten-free roll (e.g., Udi’s). Always confirm the brand of the bun and the packaging itself, and ask whether the buns are toasted on shared equipment, just to be safe.
Are Smashburger fries and shakes safe for celiacs?
It depends. Fries, tots, and other similar sides are usually wheat-free by recipe, but if fryers are shared with breaded items, they become high cross-contact risks, so you should always ask whether the fryer oil is dedicated. Shakes are safe except those with cookie mix-ins (e.g., Oreo), but blended drinks use shared blenders.
Where can I find Smashburger’s official allergen info, and how can I get confirmation?
Smashburger’s website has a neat interactive widget tool to help you filter out its menu for specific allergens–such as trying to avoid gluten and wheat–and it even allows you to customize and modify menu items to omit those allergens, along with plenty of other filters for nutritional data and lifestyle choices (e.g., vegetarian).
