Holy Deadpool & Wolverine! What the peppercorn aioli is this?
Earlier this year, Burger King rolled out the Ultimate Steakhouse Whopper, featuring a 1/4 lb beef patty topped with onion rings, sautéed mushrooms, bacon, Swiss cheese, and peppercorn aioli, on a toasted sesame seed bun.
In my review, I noted that it was a derivative of 2025’s Steakhouse Bacon Whopper, which featured a quarter-pound beef patty topped with lettuce, tomato, crispy onions, A.1. Sauce, bacon, Swiss cheese, and peppercorn aioli on a toasted sesame seed bun.
In this review, I’m going to point out that the new Peppercorn BLT Whopper is a derivative of both — and really should’ve been called the Ultimate Steakhouse Bacon Whopper. It features a quarter-pound beef patty topped with lettuce, tomato, bacon, Swiss cheese, and peppercorn aioli on a toasted sesame seed bun.
Either other universes are sending peppercorn aioli-topped Whoppers to ours, or Burger King’s Whopper creations are now produced via AI using the following prompt: “I’m the fast food burger chain, Burger King, and accidentally purchased too much peppercorn aioli. Using toppings I always have in stock, come up with new Whopper variations.”
Despite their many ingredient similarities, the peppercorn aioli Whopper variants have had different taste profiles. The Ultimate Steakhouse Whopper had a mushroom & Swiss vibe, the Steakhouse Bacon Whopper had a Western burger vibe, and this new one has a less straightforward vibe.

I didn’t notice this with the previous peppercorn aioli-topped Whoppers, but the sauce doesn’t really have a strong peppercorn flavor. Instead, I taste something that’s Caesar dressing-adjacent with most bites, and the crunch of the lettuce with it further convinces my brain that I might be eating a Caesar salad that was made in front of me at a high-end steakhouse by someone in a tuxedo.

But there are also times when the savory, porky bacon takes over and, along with the mild cheese, makes it taste like a no frills deluxe bacon cheeseburger, but with Swiss. While the beef patty offered a meaty flavor, I didn’t taste that usual flame-grilled-ness from it, which is a strange thing to miss in a Whopper.
Overall, it’s an okay tasting Whopper, and, if you’re from another universe, it’s not worth traveling to this one to try it.
