Description

This White Castle Sliders recipe recreates the iconic bite-sized burgers at home, featuring juicy seasoned beef patties, caramelized onions, and melted cheese on soft slider buns. Perfect for a party appetizer or fun family meal, these sliders combine savory, tangy, and sweet flavors with a quick and easy stovetop and oven-toasting method.


Ingredients

Scale

Slider Patties

  • 1 lb ground beef (80% lean)
  • 1 small onion, finely chopped
  • Salt and pepper to taste

Buns & Toppings

  • 12 small slider buns (such as Kings Hawaiian or similar soft buns)
  • 6 slices American cheese, cut in half (optional)
  • 1 tablespoon mustard (optional)
  • 1 tablespoon ketchup (optional)
  • 1 tablespoon butter (for toasting buns)


Instructions

  1. Preheat Oven: Preheat your oven to 350°F (175°C) to prepare for toasting the slider buns.
  2. Caramelize Onion: In a large skillet over medium heat, sauté the finely chopped onion in a bit of oil or butter until softened and caramelized, about 10-15 minutes. Remove from heat and set aside.
  3. Toast Buns: Arrange the slider buns on a baking sheet and toast in the preheated oven for about 5 minutes until they are lightly golden.
  4. Prepare Patty: While the buns toast, form the ground beef into one large flat patty roughly the size of your baking sheet. Season both sides with salt and pepper evenly.
  5. Cook Patty: Heat a large skillet or griddle over medium heat, then place the beef patty onto it. Cook for about 4-5 minutes per side until browned and cooked through in the center.
  6. Cut Patty: Once cooked, transfer the patty to a cutting board and slice into 12 square portions, sized to fit each slider bun.
  7. Assemble Sliders: Place each beef square on a toasted bun bottom. Top with a spoonful of caramelized onion, half a slice of American cheese, and add mustard or ketchup if using. Finish by placing the bun top on each slider.
  8. Serve: Serve the sliders immediately while warm and enjoy the classic White Castle flavor at home!

Notes

  • Make sure to caramelize onions slowly to maximize flavor without burning.
  • Using a single large patty ensures uniform size and quick cooking compared to individual small patties.
  • Slider buns like King’s Hawaiian add a slight sweetness that complements the savory beef and onions.
  • Cheese, mustard, and ketchup are optional but recommended for authentic White Castle flavor.
  • Serve immediately for best texture as buns may get soggy after sitting.
