Sesame Allergy — State-Specific Warning
This is the most important allergen detail most people miss.
In-N-Out buns contain sesame flour in Texas, Colorado, and Tennessee locations only. California buns do not contain sesame.
If you have a sesame allergy and you’re ordering in Texas, Colorado, or Tennessee — the standard bun is not safe. Order Protein Style (lettuce wrap) to avoid the sesame-containing bun entirely.
California, Nevada, Arizona, Utah, Oregon, and Idaho locations are not affected — their buns contain no sesame ingredient.
Gluten-Free Options at In-N-Out
In-N-Out does not have a certified gluten-free kitchen. However, several items contain no gluten ingredients:
Safe by ingredients (gluten-free):
- French fries — potatoes, sunflower oil, seasoning
- Beef patty — no gluten ingredients
- Protein Style burger — lettuce wrap replaces the bun
- Flying Dutchman — no bun
- All fountain drinks, iced tea, lemonade, coffee
How to order gluten-free: Say “Protein Style” — the bun is replaced with iceberg lettuce. This removes all wheat/gluten from the bun.
Important: In-N-Out states officially that food is prepared in kitchens where cross-contact with allergens may occur. The grill and prep surfaces are shared. For customers with celiac disease, this cross-contact risk is significant — speak with the location manager before ordering.
Dairy-Free Options at In-N-Out
Dairy appears in cheese, milkshakes, milk, and hot cocoa. Everything else is dairy-free by ingredients.
Dairy-free items:
- Hamburger (no cheese) with no spread — ask for ketchup/mustard instead
- French fries
- Beef patty
- All fountain drinks, iced tea, lemonade, coffee
- Protein Style with no cheese
How to order dairy-free: “Hamburger, no cheese, no spread, ketchup only” — this removes all dairy-containing ingredients from the burger.
Not dairy-free: Cheeseburger, Double-Double, Grilled Cheese, Flying Dutchman, all milkshakes, milk, hot cocoa.
Egg Allergy — What to Avoid
Eggs appear in only one In-N-Out ingredient: the spread (the Thousand Island-style sauce used on all burgers by default).
To avoid eggs: Say “no spread” when ordering. Replace with ketchup, mustard, or both — all egg-free.
Soy Allergy — Sources at In-N-Out
Soy appears in three places:
| Source | Item |
|---|---|
| Bun (soybean oil) | All bun-based burgers |
| American Cheese (soy lecithin) | All cheese items |
| Spread (soybean oil) | All burgers with spread |
To reduce soy exposure: Order Protein Style (removes bun), no cheese, no spread.
Peanut & Tree Nut Allergy
In-N-Out does not use peanuts or tree nuts as ingredients in any menu item. For most nut allergy sufferers, the menu is considered safe.
