In-N-Out Gluten Menu with Prices 2026
The In-N-Out Gluten Free Menu is one of the more friendly fast food options in the country, but the chain does not offer gluten free buns, and the kitchen does share surfaces between gluten and non gluten items. This page walks you through everything you can safely order, exactly what to say at the speaker, and where the real cross contamination risks live so you can make a fully informed choice before you pull into the drive thru.

🥗 IN-N-OUT GLUTEN FREE MENU OVERVIEW
What makes In-N-Out one of the more accessible fast food chains for gluten free diners is the chain’s general commitment to fresh, simple ingredients with very few hidden additives. The menu is short, the ingredient list for each item is transparent, and the chain publishes a full allergen guide that any customer can request at the counter. Almost everything on the standard menu is gluten free by ingredient, with one major exception. The sponge dough bun is made with wheat flour, which means a standard burger is not gluten free unless you swap the bun for a lettuce wrap.
This is exactly why Protein Style exists. The Protein Style order is the chain’s official term for any burger where the bun is removed and replaced with two large leaves of cold iceberg lettuce wrapped tightly around the patty, cheese, tomato, onion, and spread. It is available on every burger on the menu and on every secret menu burger too. The lettuce wrap is the foundation of nearly every gluten free order at the chain, and the crew at every location has been making these for decades.
The fries are also good news for gluten free customers. They are cut from whole Kennebec potatoes inside the restaurant, fried in pure sunflower oil, and the chain uses dedicated fryers exclusively for the fries with no shared oil for breaded items. This means the fries are one of the safer gluten free options on the entire menu, with much lower cross contamination risk than fries at most other fast food chains.
The shakes, fountain drinks, lemonades, iced teas, milk, hot cocoa, and coffee are all gluten free by ingredient at the ingredient level, though shakes carry a slight risk from shared blending equipment that the kitchen also uses for other items.
🍔 IN-N-OUT GLUTEN FREE BURGERS
Protein Style Hamburger
The Protein Style Hamburger is the simplest gluten free order on the menu and a good first try for anyone new to ordering this way.
Protein Style Cheeseburger
The Protein Style Cheeseburger adds one slice of melted American cheese to the basic build, which fuses to the warm patty and brings the cheese flavor into every bite.
Protein Style Double-Double
The Protein Style Double-Double is the gluten free version of the chain’s signature burger, and many regulars argue it tastes better than the regular Double-Double because the lettuce wrap forces you to focus on the beef, cheese, and spread without the bread filler. You get two fresh patties, two slices of melted American cheese, the standard lettuce, tomato, onion, and spread, all wrapped in iceberg lettuce.
Protein Style 3×3
For bigger appetites, the Protein Style 3×3 packs three patties and three slices of cheese into a lettuce wrap that genuinely tests the structural limits of iceberg lettuce.
Protein Style 4×4
The Protein Style 4×4 is the gluten free version of the chain’s biggest burger, and it pushes the lettuce wrap technique to its absolute limit. Four patties, four slices of cheese, the standard fillings, all wrapped in a generous bundle of iceberg lettuce.
Protein Style Animal Style Burger
The Protein Style Animal Style Burger combines two of the most popular off menu orders into a single gluten free build. The patty is cooked in a thin coat of yellow mustard, which sizzles and caramelizes into a sharp tangy crust on the surface of the beef. Then it gets stacked with extra spread, slow grilled onions, and dill pickles, all wrapped in lettuce instead of a bun. The mustard is gluten free, the grilled onions are gluten free, the pickles are gluten free, and the spread is gluten free by ingredient. This is one of the most flavor packed gluten free orders the chain offers.
Flying Dutchman
The Flying-Dutchman is naturally bunless and naturally gluten free without any modifications. You get two beef patties with two slices of melted American cheese sandwiched directly between them, with absolutely nothing else. No bun, no lettuce, no tomato, no spread, no onion.
🍟 IN-N-OUT GLUTEN FREE FRIES
The fries are one of the cleanest gluten free options on the entire menu. The chain cuts whole Kennebec potatoes inside each restaurant and fries them in pure sunflower oil. The oil is not shared with any breaded item because the chain does not sell anything breaded.
Item | Price | Calories | Gluten Free Status |
|---|---|---|---|
French Fries | $1.85 | 370 | Safe by ingredient and preparation |
Well Done Fries | Same as standard | 400 | Safe by ingredient and preparation |
Light Fries | Same as standard | 380 | Safe by ingredient and preparation |
Animal Style Fries | $6.00 | 700 to 750 | Gluten free by ingredient, requires fresh prep to avoid cross contamination |

🥤 IN-N-OUT GLUTEN FREE DRINKS AND SHAKES
Fully Safe Drinks
The fountain sodas including Coke, Cherry Coke, Diet Coke, 7Up, Dr Pepper, Barq’s Root Beer, the iced teas in all three styles, the Sig Pink Lemonade, the Lite Pink Lemonade, bottled water, and the milk carton are all gluten free at the ingredient level and have no meaningful cross contamination risk because they are dispensed from sealed systems or pre packaged containers.
Hot Drinks
Coffee and Hot Cocoa are both gluten free by ingredient. The Hot Cocoa is made with real cocoa and steamed milk rather than a powdered mix, which keeps the ingredient list short. Coffee is brewed from real grounds with no flavor additives.
Shakes
The Chocolate Shake, Strawberry Shake, and Vanilla Shake are all made with real ice cream that is gluten free by ingredient. The shake mixing equipment is sometimes used for milk based drinks like the Hot Cocoa, but it is not used for any wheat based item. For most gluten sensitive diners the shakes are safe. For celiac patients, ask the crew to use a freshly cleaned mixer cup if you are concerned.

🧂 IN-N-OUT GLUTEN FREE SAUCES AND ADD-ONS
Signature Spread
The spread is made with mayonnaise, ketchup, sweet pickle relish, vinegar, sugar, and a proprietary blend of spices. None of these ingredients contain gluten. However, the spread is mixed and stored in a kitchen where wheat products are also handled, which introduces a small cross contamination risk. For mild gluten intolerance, this is fine. For severe celiac disease, consider ordering “no spread” to eliminate the variable entirely.
Add-On Options Status
Add-On | Gluten Free Status |
|---|---|
Spread | Yes by ingredient, slight cross contamination risk |
Ketchup | Yes |
Mustard (used in Animal Style and Mustard Grilled) | Yes |
Pickles | Yes |

Chopped Chilies | Yes |
Tomato | Yes |
Iceberg Lettuce | Yes |

The In-N-Out Gluten Free Menu is one of the friendlier fast food options in the country for anyone managing a gluten free diet, and the Protein Style technique gives you a way to enjoy nearly every burger on the menu without the bun. The chain’s commitment to fresh, simple ingredients works in your favor, the dedicated fry oil is a major win for cross contamination concerns, and the crew at every location has been making Protein Style orders for decades.
