I Tried Burger King’s New Peppercorn BLT Whopper and Loved It

Sometimes I get ahead of myself when filming new product reviews. That is exactly what happened when I sampled the new Peppercorn BLT Whopper from Burger King. I had my phone ready and the sandwich in hand, which seemed like enough preparation. However, I quickly realized I needed to actually understand what I was eating. After taking a bite, I struggled to identify the flavor components—was the peppery taste in the meat or the sauce? I also found myself wondering about the type of cheese and why it appeared white.

After doing a quick search to clarify the ingredients, I can confirm that the Peppercorn BLT Whopper features a flame-grilled Whopper patty, Swiss cheese, bacon, lettuce, tomato, and a peppercorn aioli, all served on a sesame seed bun. The most important takeaway is that it is genuinely delicious. Here is my full review.

The Whopper is consistently saucy, and this version is no different. The peppercorn aioli is delightful, offering a zippy flavor that distinguishes it from standard mayonnaise, though I initially assumed the pepper notes came from the burger seasoning. My colleagues Ariana Losch and Justine Sterling both noted that the sauce reminded them of the creamy condiments often served with sushi. It pairs beautifully with the bacon. When we recently sampled McDonald’s burgers, we were disappointed by the bacon options because the meat completely dominated the flavor profile, making them taste nothing like a traditional McDonald’s burger. In contrast, this bacon provides a subtle, smoky enhancement that complements the patty perfectly. This is exactly how a bacon cheeseburger should taste.

The Swiss cheese has a texture more reminiscent of American cheese. It is slick and melty rather than stretchy, which adds a pleasant creaminess to the sandwich. That said, if you are expecting a more authentic Swiss experience, you might find it underwhelming.
