Burger King Menu Allergen Guide

This guide provides lists of allergens in foods and drinks offered at Burger King restaurants.

For ease of reference, this allergen report is divided into categories that mirror the fast food giant general menu, including flame-grilled burgers, chicken and fish items, breakfast, and desserts.

Burger King Allergen Menu

Review this report for a listing of food items offered at Burger King that are made with one or more of the major food allergens. Tables indicate which allergen(s) (e.g., eggs, wheat, soy, peanuts, etc.) the fast food restaurant has declared are included in the recipes for the food.

Allergen information is based on menu items available at locations in the United States.

Flame-Grilled Burgers

Here is the declared list of allergens in Burger King burgers and cheeseburgers. We source this information from Burger King.

If you prefer dairy-free burgers, consider the hamburger, double hamburger, or Whopper.

Chicken & Fish

The common allergens listed for chicken nuggets and chicken fries apply to all available order sizes.

All chicken dishes are prepared using a shared fryer and/or toaster.

Many fast food restaurants have limited food preparation areas and do not have the space for separate fryers.

Certain menu items that are not made with a declared allergen may still come into contact with another food item made with egg, milk, wheat, or another allergen.

For example, chicken nuggets are cooked in a shared fryer that may use the same fry oil as mozzarella sticks. As such, chicken nuggets, which are made with wheat may be cooked alongside mozzarella sticks made with soy and milk.

Kids’ Menu

Burger King’s Kid’s burger and cheeseburger are prepared in a shared toaster. The chicken nuggets and fries are cooked in common oil in a shared fryer.

The following allergen chart includes food items on the kids’ menu.

Breakfast

Burger King offers a long list of breakfast options, including egg sandwiches served on a croissant or biscuit. Choose additional toppings such as bacon, sausage, or ham.

One of the newer menu items, the Egg-Normous Burrito is made with bacon, eggs, shredded cheddar cheese, hash browns, and a creamy spicy sauce served on a soft flour tortilla.

As with many of the other food products at Burger King, breakfast items may be cooked in the same fryer oil and/or toaster as other foods, which can lead to risk of cross contamination.

To avoid wheat, check out the soft serve cup (not the cone), a chocolate sundae, or the milkshake.

Drinks

Quick Overview of FDA Guidelines

Federal regulations have identified nine major food allergens: eggs, fish, milk, peanuts, sesame, shellfish, soybeans, tree nuts, and wheat.

Highly refined oil, even if derived from one of the major food allergen groups (e.g., soybeans) is exempted from federal regulations. As a result, highly refined soy oil is not considered a common allergen and thus typically not declared on menu items.

It’s important to note that certain foods may be prepared or cooked using shared equipment. Fried foods, for example, are cooked in common oil. As such, foods made without a declared food allergen may come into contact with allergens through cross-contamination.
