Eating gluten-free
The standard move is Protein Style: any burger wrapped in lettuce instead of the bun, which removes the wheat and sesame in one step. The fries are a rare fast-food comfort — they are the only item cooked in their fryer and contain nothing but potato, sunflower oil and salt.
The caution: burgers are cooked on a shared grill and buns are toasted in the same kitchen, so In-N-Out is not a certified gluten-free environment. For celiac disease, tell the crew it is an allergy order — they will take extra care with gloves and surfaces.
Milk, egg and soy
Milk appears in the cheese and the shakes. A hamburger (no cheese) with no shake is the milk-free burger order. Egg and soy hide mainly in the spread — order any burger "no spread" (or "ketchup and mustard instead") to avoid both. The bun is a sponge dough containing wheat and sesame.
Peanut and tree-nut allergies: the menu itself is essentially nut-free and the fries are cooked in sunflower (not peanut) oil — one reason the chain is a common choice for nut-allergy families. Confirm at the counter for your specific allergy.
What to say at the counter
Crews respond best to plain, specific sentences. The scripts that work:
- Gluten: "A Double-Double, Protein Style, please — it is an allergy order." (Lettuce wrap, allergy handling.)
- Milk: "A hamburger with no cheese — and can you make sure no cheese touches it?" (Allergy flag matters more than the request.)
- Egg/soy: "A cheeseburger with no spread — ketchup and mustard instead."
- Sesame: Protein Style again — the bun is the sesame source, so the wrap solves it.
The phrase "it is an allergy order" is the important one in every script: it triggers glove changes and extra care with shared surfaces, which the regular wording of an order does not.
Allergen details reflect the standard builds as of October 2026 and commonly published ingredient information. Recipes and suppliers can change — the crew and the official site are the final word.
