Burger King's 'Pepper Garlic Steak Whopper' taste test review: What does the mayonnaise-based 'Special Pepper Garlic Sauce' taste like?

Burger King's summer limited-time menu item, the 'Pepper Garlic Steak Whopper,' featuring a flame-grilled beef patty, beef brisket steak, and a special pepper garlic sauce, was released on July 17, 2026. The ' Double Pepper Garlic Steak Whopper,' with two beef patties, and the ' Cheese Pepper Garlic Steak Whopper ,' with added cheddar cheese, were also released on the same day, so I tried all three to see what they tasted like.

A new summer-only 'Steak Whopper' is here! The 'Pepper Garlic' features flame-grilled beef topped with beef brisket steak and finished with a special sauce that combines the savory flavor of garlic with a kick of pepper!

The newly introduced Pepper Garlic Steak Whopper and

I ordered and brought home the 'Pepper Garlic Steak Whopper,' 'Double Pepper Garlic Steak Whopper,' and 'Cheese Pepper Garlic Steak Whopper.'

I'll start by trying the Pepper Garlic Steak Whopper.

The beef patty is topped with beef brisket steak, onion, tomato, and lettuce. The sauce is a newly developed 'special pepper garlic sauce,' which is a mayonnaise-based sauce combined with sautéed onions, butter, garlic, and black pepper.

The beef short rib steak is cut into large pieces.

Upon tasting it, the mayonnaise flavor was dominant, masking the taste of the beef brisket steak and beef patty. The burger is called a 'Pepper Garlic Steak Whopper,' but the pepper and garlic flavors were completely hidden by the mayonnaise. Based on the name, I imagined a hearty burger with a strong garlic flavor, and the aroma of garlic was quite strong as it was being carried, but when I actually ate it, the mayonnaise completely overpowered everything. When I had several editors try it, they commented, 'Isn't the combination of steak and mayonnaise questionable in the first place?' and 'The taste is completely different from what the name suggests. I wish the garlic flavor was more prominent.'

I'll also try the Double Pepper Garlic Steak Whopper.

The basic composition is the same, but the number of beef patties has increased to two.

The addition of a second beef patty gives it a more substantial meaty presence. However, the strong garlic and pepper flavors are still barely noticeable. It feels like the mayonnaise's ability to 'bring the flavors together' is a bit too prominent.

Finally, I'll try the Cheese Pepper Garlic Steak Whopper.

This burger consists of a pepper garlic steak whopper with two extra slices of cheddar cheese.

The saltiness of the cheddar cheese enhanced the feeling of it being a hearty, substantial meal.

The individual prices are ¥1,190 (tax included) for the Pepper Garlic Steak Whopper, ¥1,590 (tax included) for the Double Pepper Garlic Steak Whopper, and ¥1,290 (tax included) for the Cheese Pepper Garlic Steak Whopper.
