The pretzel bun was a game-changer for our burger night! Soft, salty exterior with that signature ButterBurger taste - impossibly juicy and satisfying.
Shape fresh ground beef into two 1/2 lb patties, pressing flat (about 1/2 inch thick) and season both sides generously with kosher salt and black pepper.
Heat a griddle or skillet over medium-high until hot (about 400°F); cook patties 3–4 minutes per side without pressing, just until a deeply browned crust forms and juices run clear.
While burgers cook, slice pretzel buns horizontally. Spread 1 tbsp Wisconsin butter on each cut side; toast buns face-down in a hot skillet or griddle until golden and slightly crisp (about 1–2 minutes). Copycat tip: Only real Wisconsin butter captures Culver's ButterBurger signature flavor.
During the final minute of cooking, top each patty with a slice of Wisconsin cheddar; cover to melt cheese. Remove patties and let rest 1 minute.
To assemble: Place lettuce and tomato on the bottom bun, add cheesy beef patty, and cap with the toasted, buttered pretzel bun. Enjoy immediately for maximum juiciness and authentic Culver's experience!
