Homemade White Castle Burgers

Total Time: 1 hour, 10 minutes
Yield: 12


  • 1 pound ground beef 
  • ½ cup dehydrated onions
  • 1 cup warm water
  • Salt, to taste
  • Pepper, to taste
  • 12 slices American cheese
  • 12 dill pickles, sliced
  • 12 small slider buns
  • Mustard, to garnish
  • ½ cup ketchup
  • ½ cup creamy French dressing
  • 1 tablespoon Worcestershire sauce 
  • 1 tablespoon spicy horseradish sauce 
  • 2 teaspoons brown sugar 
  • 1½ teaspoons cayenne pepper
  • ½ teaspoon garlic salt 


  • On a parchment paper-lined work space, roll out the ground beef until approximately ¼ inch thick. Cut into 3x3 inch squares, and use a straw or wooden dowel to put 5 small holes in each one (this can be done several days in advance, if desired). Set the patties on a tray and freeze them for a minimum of 1 hour. 
  • Place the dehydrated onions in a cup of warm water to reconstitute them. 
  • Make The Firecracker Ketchup: In a small pot, combine the creamy French dressing, horseradish, garlic salt, brown sugar, cayenne pepper, Worcestershire sauce, and ketchup. Stir well, set aside, and chill until ready to serve. 
  • Bring grill to medium heat. Using a cast iron pan or skillet, spread the hydrated onions out along the pan and add the frozen meat patties. Sprinkle with salt and pepper. 
  • Place a bun half on each slider and grill for approximately 5 to 6 minutes while letting the other bun steam. Flip each patty once and top with cheese.
  • Add the mustard, pickles, and firecracker ketchup to each patty. Top with the remaining steamed buns, and serve.
