Burger King Impossible Whopper
The Burger King Impossible Whopper is a plant-based version of the chain’s signature Whopper. It features a flame-grilled Impossible patty topped with juicy tomatoes, crisp lettuce, creamy mayonnaise, ketchup, crunchy pickles, and sliced white onions on a toasted sesame seed bun.
The Impossible patty is made from plants rather than beef, but it is designed to provide a savory flavor and texture similar to a traditional hamburger. Burger King describes the sandwich as “100% Whopper, 0% Beef” and notes that the patty is normally cooked on the same broiler as its beef patties. An alternative cooking method may be requested.
Price
Burger King does not use one guaranteed nationwide Whopper price. The final cost depends on the restaurant, city, ordering method, and meal size. Third-party delivery platforms may charge more than restaurant pickup.

Removing mayonnaise can substantially reduce the sandwich’s fat and calories. Adding American cheese increases calories, saturated fat, sodium, protein, and milk allergens.
A meal contains considerably more calories because fries or another side and a beverage are added. Water or a zero-sugar drink adds fewer calories than a regular soft drink, shake, or sweetened beverage.
Why You Should Try Burger King Impossible Whopper
Burger King Impossible Whopper is suitable for customers who want the familiar toppings and flame-grilled character of a Whopper without a beef patty.
The plant-based patty provides a savory center, while tomatoes, lettuce, pickles, and onions add freshness, acidity, and crunch. Ketchup contributes sweetness, and mayonnaise adds a rich and creamy texture.
The sandwich also provides approximately 29 grams of protein according to its commonly published nutrition profile. Its toppings can be customized in much the same way as a traditional Whopper.
The Impossible Whopper may appeal to vegetarians, flexitarians, customers reducing their beef consumption, or anyone curious about plant-based meat.
