Ingredients

• 1 pound ground beef
• 1 large yellow onion, finely chopped
• 0.5 cup water
• 1 teaspoon salt
• 0.5 teaspoon black pepper
• 2 tablespoons milk
• 0.25 cup panko breadcrumbs
• 6 slices American cheese slices
• 12 slider buns (or dinner rolls sliced in half)
• 12 pickle slices
• 2 tablespoons mustard

Directions

Step 1

In a mixing bowl, combine ground beef, milk, panko breadcrumbs, salt, and black pepper until mixed well. Avoid overmixing to keep the patties tender.

Step 2

Line a sheet pan with parchment paper. Spread the beef mixture into an even rectangular layer about 1/4 inch thick to mimic the iconic White Castle patty shape.

Step 3

Use a knife or pizza cutter to score the meat into 2-inch squares. Poke 5 small holes into each square to help them cook evenly, just like the original sliders.

Step 4

Refrigerate the pan of beef for about 10-15 minutes to help it firm up and make it easier to handle.

Step 5

Meanwhile, finely chop the yellow onion and scatter it across a griddle or large skillet.

Step 6

Pour 1/2 cup of water over the onions and heat on medium-low. The onions will steam and help give the burgers their signature flavor.

Step 7

Transfer the chilled burger patties onto the cooking onions. Don't separate the squares yet; they will pull apart after cooking.

Step 8

Cover the griddle or skillet with a lid to trap the steam and cook for about 3-5 minutes, or until the patties are cooked through.

Step 9

Place a slice of American cheese on each patty and let it melt for about 1 minute.

Step 10

Split the slider buns and place the bottom halves on top of the patties and steamed onions. Let them warm for 1-2 minutes.

Step 11

Carefully transfer the patties and bun bottoms onto a plate using a spatula. Cover each with a pickle slice and mustard. Add the top bun to finish the slider.

Step 12

Serve immediately and enjoy the authentic taste of White Castle at home!
