White Castle Hamburger Recipe

Ground beef: The main protein for the sliders, providing a rich and savory flavor.

Onions: Finely chopped to add a sweet and aromatic element to the burgers.

Slider buns: Small, soft buns that are perfect for mini hamburgers.

Pickles: Sliced pickles add a tangy crunch to each bite.

Salt: Enhances the natural flavors of the beef.

Black pepper: Adds a hint of spice and depth to the patties.

When spreading the ground beef on the baking sheet, use a piece of parchment paper on top of the meat and a rolling pin to ensure an even thickness. This will help the patties cook uniformly and make it easier to cut them into perfect squares.
