If you grew up loving those little square burgers with the soft buns and grilled onions… this one’s for you.
These Homemade White Castle Sliders give you all the nostalgic flavor — but made with real ingredients you can feel good about.

They’re juicy, onion-packed, and baked together on a sheet for that classic steamed slider feel. Whether you’re feeding a hungry crew, planning a fun weekend dinner, or just craving a fast-food favorite made clean, these little burgers hit the spot.

Ingredients:

• 1 lb ground beef (85/15 or lean grass-fed)

• ½ tsp onion powder

• Salt and pepper to taste

• ½ cup finely diced onion

• 8–9 whole wheat or slider-size buns (soft, not crusty)

• 4 slices cheddar or American-style cheese (cut into quarters)

• Optional toppings: dill pickles, mustard, ketchup

Instructions:

1. Preheat oven to 400°F
   Line a rimmed baking sheet with parchment paper or foil.

2. Make the beef layer
   Press ground beef evenly into a thin rectangle (about ¼" thick) directly onto the lined baking sheet — roughly the size of the bun layout. Season with onion powder, salt, and pepper. Sprinkle finely diced onion evenly over the beef.

3. Bake the beef
   Bake for 12–15 minutes, or until fully cooked. The edges may shrink slightly — that’s okay!

4. Cut and layer
   Remove from oven and cut the beef into squares to match the bun size. Place cheese pieces on each square. Let melt for a minute.

5. Assemble the sliders
   Slice buns in half if needed. Lay bottom buns in a clean baking dish or sheet, place a burger square with melted cheese on each, add optional toppings like pickles or mustard, then place top buns on.

6. Steam-style finish (optional)
   Cover the entire dish tightly with foil and bake for 5 more minutes to steam the buns slightly for that classic soft texture.

7. Serve hot
   Serve with baked fries, sweet pickles, or a big salad for a fun, clean comfort meal!

Sarah’s Tips:

• Mini meal prep win: Cook the beef layer ahead and assemble to bake later.

• Make it dairy-free: Use plant-based cheese or skip it — the flavor still shines.

• Want a lower carb option? Serve slider patties on lettuce wraps or grain-free buns.

• Add some crunch: Shredded lettuce and tomato slices make great toppings too!

Flavorful Conclusion:

These Homemade White Castle Sliders bring all the cozy, nostalgic comfort — with clean, simple ingredients and way less grease. They’re fun to make, fun to eat, and perfect for sharing with the whole family (or keeping all to yourself — I won’t tell!).
