White Castle Slider
Total time: 20 minutes
Ingredients
  • 1/4 pound ground chuck
  • 1/4 pound ground beef
  • salt and pepper, to taste
  • 4 tablespoon butter
  • 1 cup finely diced onions
  • 6 dill pickle slices
  • 6 square dinner rolls
Directions
  1. In a medium sized bowl, mix together the beef and chuck, carefully so that you do not overmix the meat.
  2. On a clean surface or a cutting board, lay out 1 sheet of parchment paper.
  3. Place the beef in the center and top with another sheet of parchment paper.
  4. Roll out the beef until very thin, about ¼-inch thick, into a rough rectangle that is about 7-by-10-inches.
  5. Trim the edges of the square and use the scraps to pat into a neat rectangle that is 6-by-9-inches.
  6. Season the hamburger square generously with salt and pepper.
  7. Using a spatula, cut six 3-by-3-inch patties out of the square.
  8. Using a straw, poke 5 holes in each patty, one near each corner and one in the center.
  9. In a 12-inch skillet, melt the butter.
  10. Add the diced onion, season lightly with salt, and sauté in the butter for 1-2 minutes until it begins to sweat.
  11. Spread the onions evenly along the bottom of the pan so that the bottom of the pan is covered.
  12. Turn the heat to medium-low, and top the bed of onions with the patties, 4 at a time, seasoning side down.
  13. Allow the onions to "steam" the patties.
  14. Cover and cook the patties until they are no longer pink and cooked through, about 4 minutes.
  15. Meanwhile, dampen a kitchen towel and wrap the 6 buns in it.
  16. Place in the microwave for 10-20 seconds to steam the buns.
  17. To assemble the burgers, take each patty with no more than 1 tablespoon of the cooked onions and place on the bottom ½ of the bun, onion side up.
  18. Top with 1 pickle slice and the top ½ of the bun.
  19. Serve with ketchup, if desired.
