Double Croissan Wich: Allergens at a Glance
The honest verdict
Double Croissan Wich · Burger King
The Double Croissan Wich is a Burger King breakfast sandwich with two sausage or bacon patties, a folded egg patty, and American cheese on a toasted croissant. The croissant is wheat-based and typically contains butter (milk) and may contain soy lecithin. The egg patty contains egg and may contain milk. The cheese adds milk. Sausage patties may contain soy as a filler. Peanut, tree nut, fish, shellfish, and sesame are not typical ingredients. Cross-contact with shared grills and toasters is possible. Always confirm with your specific Burger King location before ordering.
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
The Double Croissan Wich contains wheat (croissant), milk (cheese and butter), and egg (folded egg patty) as direct ingredients.
Soy may be present in the croissant dough (soy lecithin) and sausage patty (soy filler).
FDA — Food Allergen Labeling and Consumer Protection Act (FALCPA)
Shared grills and toasters at Burger King create cross-contact risk for wheat, milk, and egg.
Every major allergen, one clear grid
Each of the nine major allergens marked for Double Croissan Wich at Burger King — 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
The croissant is made with butter, and American cheese is a standard topping. The folded egg patty may also contain milk. This sandwich is not dairy-free.
- EggContains
The folded egg patty is a primary ingredient. Egg is also used in the croissant dough for browning and structure.
- Wheat / GlutenContains
The croissant is made from wheat flour. This is the primary source of gluten in the sandwich.
- SoyMay contain
Soy lecithin is often used in croissant dough as an emulsifier. Sausage patties may contain soy protein concentrate or soy flour as a filler. Refined soybean oil may be used in preparation. Confirm the specific recipe with Burger King.
- PeanutFree
Peanut is not an ingredient in the Double Croissan Wich or its components. Cross-contact is very unlikely in Burger King kitchens.
- Tree NutFree
Tree nuts are not an ingredient in the croissant, egg, cheese, or meat components. Not a concern for this item.
- FishFree
Fish is not an ingredient in any component of the Double Croissan Wich. Burger King does not fry fish items on breakfast grills.
- ShellfishFree
Shellfish is not an ingredient in this breakfast sandwich. Not a concern.
- SesameFree
Sesame is not a typical ingredient in croissant dough or other components. The croissant is not seeded. Confirm if sesame flour or oil is used in the dough at your location.
“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 double croissan wich. Always name your allergy when you order and ask staff to confirm — a modification only helps if the kitchen prepares it separately.
Order without cheese
Request the Croissan Wich without egg (if available)
Ask for the sandwich on a bun or English muffin instead of croissant
Verify the sausage patty ingredients for soy content
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
Burger King uses shared grills and toasters for breakfast items. The croissant is toasted on the same surfaces as other bread items. The egg and sausage patties are cooked on shared flat-top grills. Cross-contact with wheat, milk, egg, and soy from other breakfast items is possible. Ask your location about dedicated preparation surfaces.
If your allergy is severe
For anaphylactic allergy to wheat, milk, or egg, the Double Croissan Wich is not a safe choice. The croissant, cheese, and egg patty are direct sources of these allergens, and cross-contact on shared grills and toasters is likely. Carry your epinephrine auto-injector. If you cannot confirm preparation details, consider a non-breakfast item or a different restaurant.
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
The Double Croissan Wich has two sausage or bacon patties instead of one. The allergen profile is the same — both contain wheat (croissant), milk (cheese and butter), and egg (folded egg patty). The double version doubles the meat but does not change the allergen sources. The fully loaded Croissan Wich adds hash browns inside the sandwich, which introduces potato (free of Big-9 allergens) but may add soy from the hash brown seasoning.
Yes. The croissant is made from wheat flour, which contains gluten. There is no gluten-free croissant option at Burger King. If you need a gluten-free breakfast sandwich, consider a different restaurant that offers gluten-free bread or a breakfast bowl without bread.
Burger King uses a folded egg patty made from liquid eggs. It contains egg as the primary ingredient and may contain milk, butter, or oil for cooking. It is not a whole cracked egg. The allergen concern is the same — egg is present. If you have an egg allergy, this component must be removed or the sandwich avoided.
Yes, you can order without cheese to remove the milk from American cheese. However, the croissant still contains butter (milk), so the sandwich is not dairy-free even without cheese. If you need a dairy-free option, you would need to avoid the croissant entirely and choose a different bread or breakfast item.
Burger King publishes an allergen menu online that lists the major allergens for each menu item. However, recipes vary by location and change over time. The official allergen menu is the best source for current information. Always confirm with the specific restaurant before ordering, especially if you have a severe allergy.
