Burger King 'Big Mouth White' Tasting Review: What Does the White Sauce Taste Like?

' Big Mouth White, ' which uses white cheese sauce with Camembert cheese and Gouda cheese slices, appeared as a limited-time menu item at Burger King on Friday, January 30, 2026. In addition to the ' Double Beef Big Mouth White Burger ,' which sandwiches two flame-grilled beef patties and four smoky bacon, there is also the ' Chicken & Beef Big Mouth White Burger ,' which sandwiches one beef patty and one chicken patty. I tried both to see what they taste like.

From the hugely popular 'Big Mouth' series comes the new 'Big Mouth White,' a combination of flame-grilled 100% beef with rich white cheese sauce and Gouda cheese!

Two types of Big Mouth White are featured.

I ordered both and brought them home.

Take home two Double Beef Big Mouth White Burgers and two Chicken & Beef Big Mouth White Burgers.

This is the Chicken & Beef Big Mouth White Burger. The beef patty is spilling out.

It consists of two beef patties topped with two slices of Gouda cheese, mayonnaise, ketchup, white cheese sauce, pickles, and four slices of bacon. The white cheese sauce is made with Camembert cheese and garlic.

When you eat it, you can taste the strong flavor of the beef patty, mayonnaise, and ketchup. Gouda and Camembert cheeses are used, but the cheese flavor is hidden in the background. The chewy texture of the bacon is great. Although it is a burger with a lot of meat and cheese, the mayonnaise, ketchup, and pickles give it a refreshing aftertaste that is not too heavy.

I also tried the Chicken & Beef Big Mouth White Burger. When I opened the wrapper, a large beef patty and chicken patty protruded from the bun.

The inside is like this: one beef patty and one chicken patty sandwiched in between, two slices of Gouda cheese, mayonnaise sauce, white cheese sauce, and pickles.

The chicken patty is thick, so you have to open your mouth wide to eat it, making it a truly 'Big Mouth' burger. The chicken patty has a crunchy coating and a moist texture inside. The chicken patty's strong chicken flavor and saltiness overshadowed the flavor of the white cheese sauce and beef patty. I recommend this burger for those who want to eat chicken, but if you want to enjoy the beef patty and white cheese sauce, I recommend the Double Beef Big Mouth White Burger.

The price for the Double Beef Big Mouth White Burger is 1,290 yen (tax included), and the Chicken & Beef Big Mouth White Burger is 1,140 yen (tax included). Both will be available for a limited time starting January 30, 2026 (Friday).
