Allergens deserve a closer look.

In-N-Out’s allergen chart identifies milk, egg, soy, wheat and sesame in particular ingredients or regional builds. The company states that it cannot guarantee food will avoid allergen exposure.

Which components list common allergens?

The table summarizes a dated official document. Check the current ingredient listing and regional notes before using it for an order. The current online nutrition page may reflect later ingredient changes.

Why regional bun notes matter

The official chart distinguishes bun ingredients by state. A statement that every bun has exactly the same allergen profile would erase that distinction. Manufacturing-facility notes also differ from allergens intentionally included in the recipe.

Ask staff which ingredients apply to the restaurant you are visiting, especially when a source and a menu board appear to use different versions.

Does removing an ingredient remove all exposure?

Omitting cheese removes that requested component; it does not guarantee the food was prepared without contact with milk. Likewise, a lettuce wrap changes the build without proving separation from wheat.

See the gluten-free ordering guide for the difference between a bun substitution and a preparation guarantee.

How to discuss an allergy when ordering

  1. State the allergen clearly before describing your food order.
  2. Identify every part of the meal, including sauce, toppings and drink.
  3. Ask staff to check the current ingredients and explain preparation limits.
  4. Use the restaurant’s answer to decide whether the order meets your requirements.

The official chart lists customer service at (800) 786-1000 for further allergen questions. This independent guide cannot assess the safety of an individual preparation.
