How to order gluten-free
- Ask for any burger Protein Style. The lettuce wrap replaces the bun, the one item where the chart lists wheat. A Double-Double Protein Style is 460 calories; a Hamburger Protein Style is 210.
- Fries: not on the allergen chart, so In-N-Out lists no known major allergens for them (360 calories per order). Ask how they're cooked at your location if you need to be strict.
- Drinks and shakes: the chart shows no wheat in the shakes. It marks hot cocoa and the marshmallow bits as made where wheat may be present.
- Tell the cashier about the allergy. In-N-Out says it will make a reasonable effort to meet allergy requests, but can't guarantee food won't touch an allergen.
In-N-Out allergen chart
This is every item on In-N-Out's allergen chart. "Contains" means the allergen is an ingredient. "May contain" means the item is made in a facility where the allergen is present, possibly on the same equipment.

In-N-Out's note: "If a food/menu item is not listed on this chart, then it is not known to have any of the 9 major allergens nor any cross-contact risk. If a major allergen is not listed, it is not a known ingredient nor a cross-contact risk in any of our products." Fish and shellfish don't appear on the chart at all.
Which items have wheat
Contains wheat: Bun. That's the bun on every Hamburger, Cheeseburger and Double-Double, and anything served on one.
May contain wheat (shared facility): Hot Cocoa and Marshmallow Bits.
No wheat listed: cheese, spread, the three shakes, milk, the creamers and every item not on the chart, including the patties, fries, lettuce, tomato, onions and sodas.
The chart covers the major allergens, including wheat. Gluten can also come from barley or rye, which the chart doesn't track, so people with celiac disease should confirm with In-N-Out.
Other allergens: milk, soy, egg, sesame
- Milk: cheese, milk, the shakes, half & half creamer and hot cocoa contain it; the bun, oat milk creamer and marshmallow bits may contain it. For no dairy as an ingredient, order a Hamburger Protein Style (no cheese) and skip the shakes.
- Egg: the spread contains it; the shakes, half & half creamer, hot cocoa and marshmallow bits may contain it. Ask for mustard and ketchup instead of spread; In-N-Out publishes nutrition for that version too.
- Soy: cheese, the chocolate shake and hot cocoa contain it; the bun, strawberry and vanilla shakes, half & half creamer and marshmallow bits may contain it.
- Sesame: the bun and marshmallow bits may contain it.
- Peanuts and tree nuts: no In-N-Out item lists them as an ingredient. The oat milk creamer, hot cocoa and marshmallow bits may contain tree nuts, and the marshmallow bits may contain peanuts.
Cross-contact
In-N-Out's nutrition page says: "Our food is prepared in kitchen spaces where cross-contact with allergens may occur. Ingredients may vary based on regional availability, seasonal changes, or supplier substitutions." For allergy questions, In-N-Out asks customers to call its Customer Service line at (800) 786-1000 and to consult a doctor about any of the listed allergens.

In-N-Out gluten-free FAQ
Is In-N-Out gluten-free?
Not entirely. In-N-Out's allergen chart lists wheat as an ingredient only in the bun. Ordering a burger Protein Style (wrapped in lettuce) removes the bun. In-N-Out also says its kitchens can have cross-contact with allergens, so it can't guarantee any item is free of them.
Are In-N-Out fries gluten-free?
In-N-Out's allergen chart doesn't list the fries, and In-N-Out says an item missing from the chart "is not known to have any of the 9 major allergens nor any cross-contact risk." If you have celiac disease, ask your restaurant how the fries are cooked.
What can I eat at In-N-Out with celiac disease?
Based on the chart, a Protein Style burger and fries have no listed wheat. In-N-Out can't rule out cross-contact (see below), so tell the cashier about your allergy and call (800) 786-1000 with questions, as In-N-Out suggests.
Does In-N-Out spread have gluten?
The allergen chart lists egg as the only major allergen in the spread; it shows no wheat. The chart covers the major allergens, not every source of gluten, so ask In-N-Out if you need certainty.
Are In-N-Out shakes gluten-free?
The chart shows no wheat in the chocolate, strawberry or vanilla shakes. They contain milk, the chocolate shake contains soy, and all three may contain soy or egg from shared equipment.
What allergens are in In-N-Out cheese?
Milk and soy, according to In-N-Out's allergen chart.
