Description

This White Castle Sliders recipe replicates the iconic small square burgers featuring seasoned ground beef baked with onions, topped with American cheese and served on soft slider buns with pickles. Perfect for a quick, nostalgic snack or party appetizer, these sliders combine simple ingredients with an easy baking method to deliver classic diner flavor at home.


Ingredients

Scale

Slider Patties

  • 1 pound ground beef (80/20)
  • 1/2 teaspoon salt
  • 1/4 teaspoon black pepper
  • 1/2 teaspoon garlic powder
  • 1/2 cup finely minced onion
  • 1 tablespoon water (optional, for soaking dehydrated onions)

Toppings and Buns

  • 6 slices American cheese
  • 12 slider buns or dinner rolls
  • Dill pickle slices
  • 1 tablespoon butter (optional, for toasting buns)


Instructions

  1. Preheat and Prepare Beef Mixture: Preheat your oven to 375°F (190°C). In a large mixing bowl, combine the ground beef with salt, black pepper, and garlic powder. Mix well to evenly distribute the seasonings.
  2. Form and Bake Patties: Line a rimmed 9×13-inch baking sheet with parchment paper. Press the beef mixture evenly into the pan creating one thin, flat layer. Sprinkle the finely minced onions evenly over the top. Bake in the preheated oven for 12-15 minutes until the beef is cooked through and onions are tender.
  3. Prepare Buns: While the beef is baking, slice the slider buns in half if they are not pre-split. For extra flavor, optionally butter the insides of the buns and toast them in a skillet over medium heat until golden brown.
  4. Finish Patties and Assemble: When the beef and onions are done, remove the baking sheet from the oven. Carefully blot away any excess grease with paper towels. Place slices of American cheese evenly over the hot beef and allow it to melt. Using a knife or pizza cutter, slice the beef layer into 12 equal square portions, matching each to a bun bottom.
  5. Build Sliders: Place each cheese-topped beef square onto a bun bottom, add a slice of dill pickle on top, then cover with the bun lid. Serve the sliders warm, accompanied by ketchup and mustard if desired.

Notes

  • For more authentic texture and easier slicing, freeze the beef patty mixture for about 15 minutes before pressing into the baking sheet.
  • Use dehydrated onions soaked in water instead of fresh minced onions for a retro diner flavor.
  • Optional to butter and toast buns for extra flavor and crunch.
  • Serve sliders with ketchup, mustard, or your favorite condiments for enhanced taste.
