The In N Out Allergen Menu

In N Out Burger’s menu is renowned for its simplicity, focusing on a few items that are done exceptionally well. Here’s a breakdown of their allergen considerations:


  • Hamburger: 100% pure beef patty, lettuce, tomato, spread, with or without onions, on a bun.
  • Cheeseburger: Add a slice of American cheese.
  • Double-Double: Two beef patties and two slices of cheese.
  • Modifications: For gluten allergies, any burger can be ordered “Protein Style,” wrapped in lettuce instead of a bun. Dairy allergies can be accommodated by omitting cheese.


  • French Fries: Freshly made from potatoes and fried in 100% sunflower oil. In N Out’s fries are free from cross-contamination with allergens like fish, peanuts, or tree nuts.


  • Shakes: Made from real ice cream and available in chocolate, strawberry, and vanilla flavors. Dairy-free options are not available, so those with dairy allergies should take note.

Allergen Cross-Contact

In N Out takes precautions to minimize cross-contact, but individuals with severe allergies must clearly communicate their needs when ordering.
