Burger King is testing a new King Size Sliders Box in Columbus, Ohio, and Portland, Oregon, from April 14 through May 4. Customers can order boxes of two or six sliders, with three different flavor options to choose from, including a Deluxe Slider, a Steakhouse Bacon Slider, and a Bacon & Cheese Slider.

Why it matters

This test comes as Burger King has been making broader menu changes, including its first meaningful Whopper updates in nearly a decade. The King Size Sliders Box is an attempt to offer a more customizable and shareable slider format to appeal to customers looking for a snackable burger option.

The details

The sliders start with a flame-grilled beef patty on a soft, buttery bun. The Deluxe Slider comes topped with lettuce, tomato, pickles, and burger aioli, the Steakhouse Bacon Slider has Swiss cheese, bacon, crispy onions, and peppercorn sauce, and the Bacon & Cheese Slider features American cheese, bacon, and burger aioli. Burger King is calling them 'King Size' because they're meant to sit somewhere between a true slider and a full burger.

• The King Size Sliders Box will be tested in Columbus, Ohio, and Portland, Oregon from April 14 through May 4, 2026.

What’s next

A wider national rollout of the King Size Sliders Box will depend on how the items perform in the Columbus and Portland test markets.
