Allergen details change and vary by location. This is a general guide — always confirm with the restaurant before ordering. Not official or medical advice.
Key facts
Bacon cheeseburgers typically contain wheat (bun), milk (cheese), and egg (mayonnaise) as the primary allergens.
FDA — Food Allergen Labeling and Consumer Protection Act (FALCPA)
Sesame seeds on burger buns are a common hidden allergen source for those with sesame allergy.
Shared grills in fast-food kitchens can transfer trace proteins from other menu items to burger patties.
Every major allergen, one clear grid
Each of the nine major allergens marked for Classic S Awesome Bacon Cheeseburger — Contains, May contain (cross-contact or varies), or Free. Anything we couldn't confirm defaults to "may contain," because a shared kitchen can't be ruled out without the restaurant's official menu.
- MilkContains
Cheese is a standard component of a bacon cheeseburger and is a direct source of milk protein. The bun may also contain milk as an ingredient in some recipes. Confirm the cheese type and bun recipe with the restaurant.
- EggContains
Mayonnaise is a standard condiment on bacon cheeseburgers and is made with egg yolks. Some restaurants use egg-free mayo alternatives — ask the specific location about their mayo recipe.
- Wheat / GlutenContains
The bun is wheat-based. This is the primary source of wheat in a bacon cheeseburger. There is no standard wheat-free bun at most fast-food chains. A lettuce wrap or bunless option removes this allergen.
- SoyMay contain
Soy may appear in the bun as soy flour or lecithin, or as a processing aid in the beef patty or bacon. Refined soybean oil may be used in cooking. Highly refined soy oil is FDA-exempt from allergen labeling and tolerated by most with soy allergy. Those with severe soy sensitivity should confirm with the restaurant.
- PeanutFree
Peanut is not an ingredient in standard bacon cheeseburger components. Peanut oil is not typical for cooking burgers. Cross-contact is very unlikely in standard burger preparation environments.
- Tree NutFree
Tree nuts are not an ingredient in bacon cheeseburger components. Not present in the bun, patty, cheese, bacon, or standard condiments.
- FishFree
Fish is not an ingredient in bacon cheeseburger components. Some restaurants may use shared grills for fish items — ask about grill practices if fish allergy is a concern.
- ShellfishFree
Shellfish is not an ingredient in bacon cheeseburger components. Not typical in burger preparation environments.
- SesameMay contain
Sesame seeds may appear on the bun as a topping. Some restaurants use seeded buns for their burgers. If the bun is plain (no seeds), sesame is not present. Confirm the bun type with the restaurant.
“May contain” means cross-contact is possible or the answer varies by location — not that the allergen is a listed ingredient. For a severe allergy, treat “may contain” the same as “contains” until the restaurant confirms otherwise.
Small changes that remove an allergen
Simple modifications that can take an allergen off your classic s awesome bacon cheeseburger. Always name your allergy when you order and ask staff to confirm — a modification only helps if the kitchen prepares it separately.
Order without the bun (lettuce wrap or bunless)
Order without cheese
Order without mayonnaise
Request a plain bun (no sesame seeds)
A modification lowers exposure but doesn't erase cross-contact from shared fryers, grills, or prep surfaces. For a severe allergy, confirm the prep with a manager before you eat.

Cross-contact & severe allergies
A “free of” mark on the grid above means the allergen isn't an ingredient — it doesn't mean the item was made in an allergen-free kitchen. Two things matter most:
Shared fryers & equipment
Shared grills and prep surfaces at fast-food locations mean the burger patty can pick up trace proteins from other items cooked on the same surface. Bacon is typically cooked on separate surfaces but may share equipment. The bun is handled on shared prep areas. Cross-contact risk is the same as with any standard burger item. Ask staff about grill and prep practices at your specific location.
If your allergy is severe
For anaphylactic allergy to wheat, milk, egg, or soy, confirm all ingredients and preparation practices before ordering. A bacon cheeseburger is not guaranteed safe for any of these allergens without restaurant-level confirmation. Carry your epinephrine auto-injector. If you cannot confirm preparation details, consider a bunless, cheeseless, mayo-free option or a different menu item entirely.
This guidance is general and can't account for how any single location prepares your food. The restaurant's staff and official allergen menu are the final word — when in doubt, ask, or choose something else.
❓Frequently Asked Questions
Yes, the bun is wheat-based and contains gluten. The burger patty and bacon are typically gluten-free by ingredient, but cross-contact on shared grills is possible. A bunless or lettuce-wrap option removes the primary gluten source. Confirm with the restaurant whether their patties contain any wheat-based binders or fillers.
Bacon is cured pork and does not introduce major allergens on its own. The concern is potential soy in the curing process or smoke flavoring. Some bacon products use soy-based smoke flavor or processing aids. Ask the restaurant about their bacon ingredients if soy allergy is a concern.
Yes, most restaurants will accommodate a request to remove cheese and mayonnaise. Removing cheese eliminates the milk allergen from cheese. Removing mayonnaise eliminates the egg allergen from mayo. The burger patty and bacon remain, and the bun still contains wheat. Confirm the bun does not contain milk or egg as additional ingredients.
A standard beef patty is typically free of major allergens by ingredient. The concern is soy as a processing aid or filler in some patty formulations, and cross-contact on shared grills. Some restaurants use patties with wheat-based binders or fillers. Ask the specific location about their patty ingredients if wheat or soy allergy is a concern.
It depends on the restaurant. Some locations use seeded buns with sesame seeds on top, while others use plain buns. If sesame allergy is a concern, ask the restaurant whether their standard bun for this burger has sesame seeds. A plain bun request may be accommodated if the seeded bun is standard.
