The honest verdict
Garlic King Burger · Burger King
The Garlic King Burger is a specialty burger from Burger King featuring a flame-grilled beef patty, garlic butter spread, garlic aioli, cheese, lettuce, and tomato on a sesame-seeded bun. The allergen profile is anchored by wheat (bun), milk (cheese, garlic butter), egg (aioli), and sesame (seeded bun). Soy may be present in refined oil or sauces. Peanut, tree nut, fish, and shellfish are not typical ingredients. Cross-contact via shared grills and fryers is possible. Always confirm with your specific Burger King location before ordering, as recipes and preparation methods vary by region and over time.

Key facts
The Garlic King Burger is a limited-time or regional specialty burger from Burger King, featuring garlic butter and garlic aioli.
Burger King's standard buns contain wheat and are topped with sesame seeds, making them a source of both allergens.
Garlic aioli is egg-based (mayonnaise), adding egg as an allergen beyond the standard burger components.
Every major allergen, one clear grid
Each of the nine major allergens marked for Garlic King Burger 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 Garlic King Burger contains cheese (American or similar) and garlic butter spread, both of which are dairy-based. The garlic butter is a key component of this specialty burger. Those with milk allergy should request the burger without cheese and without garlic butter.
- EggContains
The garlic aioli (mayonnaise-based sauce) on the Garlic King Burger contains egg. Standard burger mayonnaise is egg-based. Request the burger without aioli to remove this allergen.
- Wheat / GlutenContains
The burger bun is wheat-based. Burger King's standard buns contain wheat flour. There is no standard gluten-free bun option at most locations.
- SoyMay contain
Soybean oil is used in Burger King's fryers and may be present in the garlic aioli or other sauces. Highly refined soy oil is FDA-exempt from allergen labeling and tolerated by most with soy allergy. Those with severe soy sensitivity should confirm the specific oil and sauce ingredients used.
- PeanutFree
Peanut is not an ingredient in the Garlic King Burger or its components. Cross-contact is very unlikely in Burger King's kitchen environment.
- Tree NutFree
Tree nuts are not an ingredient in the Garlic King Burger or its components.
- FishFree
Fish is not an ingredient in the Garlic King Burger. Cross-contact is unlikely unless the restaurant also prepares fish items on shared surfaces.
- ShellfishFree
Shellfish is not an ingredient in the Garlic King Burger.
- SesameContains
Burger King's standard burger buns are topped with sesame seeds. The Garlic King Burger is served on a sesame-seeded bun. Those with sesame allergy should request a bun without sesame seeds if available, or order the burger without the bun.
“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 garlic king burger. 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 and without garlic butter spread
Order without garlic aioli (mayo-based sauce)
Request a bun without sesame seeds, or order the burger in a lettuce wrap
Order the burger without the bun entirely (lettuce wrap)
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's flame-grilled patties are cooked on shared grills that also cook other menu items. The garlic butter and aioli are applied in the assembly area where cross-contact with other ingredients is possible. Fries and onion rings are cooked in shared fryers. Ask staff about preparation practices at your specific location.
If your allergy is severe
For anaphylactic allergy to wheat, milk, egg, or sesame, the Garlic King Burger is not safe without significant modifications. Even with modifications, cross-contact on shared grills and prep surfaces is possible. Carry your epinephrine auto-injector. If you cannot confirm preparation details with the restaurant, choose a simpler menu item with fewer allergen-containing components.
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 Garlic King Burger contains dairy from two sources: the cheese slice (American cheese) and the garlic butter spread. The garlic butter is a key differentiating component of this specialty burger. To make it dairy-free, request the burger without cheese and without garlic butter. The patty itself is dairy-free, and the aioli is egg-based but not dairy-based.
No. The standard bun is wheat-based, making the burger as-served not gluten-free. Burger King does not offer a standard gluten-free bun option. A lettuce wrap removes the wheat, but cross-contact from shared grills and prep surfaces is a concern for those with celiac disease or severe wheat allergy.
The Garlic King Burger adds two garlic-specific components: garlic butter (adds dairy) and garlic aioli (adds egg). A regular Whopper has mayonnaise (egg) and cheese (dairy) as optional, but the Garlic King Burger's garlic butter is a fixed ingredient. The sesame-seeded bun is shared with the Whopper. The garlic itself is not a common allergen, but the butter and aioli vehicles for it introduce additional allergens beyond a standard Whopper.
Yes. Garlic aioli is traditionally a mayonnaise-based sauce, and Burger King's version contains egg from the mayonnaise. This is a confirmed source of egg allergen. To remove egg, order the burger without aioli. The garlic butter spread does not contain egg, but it does contain dairy.
Yes, you can request the Garlic King Burger as a lettuce wrap or 'no bun' order. This removes the wheat and sesame allergens from the bun. However, the patty and other toppings will still be prepared on shared surfaces. Confirm with the restaurant that they can accommodate a bunless preparation without cross-contact from bun crumbs on the prep surface.
