Ingredients
- 1 (12 oz) package of White Castle sliders (8-pack)
- 1 lb ground beef
- 1 small onion, diced
- 1-2 tablespoons garlic, minced
- 1 teaspoon Worcestershire sauce
- 1 teaspoon mustard
- 1/2 teaspoon salt
- 1/4 teaspoon black pepper
- 1 (8 oz) package of shredded cheddar cheese
- 6 large eggs
- 2 cups milk
- 1 (10.5 oz) can of cream of mushroom soup
- 1 tablespoon olive oil
- Fresh parsley, chopped (for garnish)
Directions
- Preheat your oven. Preheat the oven to 350°F (175°C).
- Cook the beef. In a large skillet over medium heat, add olive oil and sauté the diced onions until translucent. Add minced garlic and ground beef. Cook until browned, breaking the meat apart with a spatula.
- Season the mixture. Stir in Worcestershire sauce, mustard, salt, and pepper, mixing until well combined. Drain excess fat if necessary. Remove from heat and let it cool slightly.
- Prepare the sliders. In a greased 9×13-inch baking dish, layer the bottom with the White Castle sliders, cutting them in half if necessary to fit evenly.
- Add the beef mixture. Spread the cooked ground beef over the sliders, making sure to cover them evenly.
- Add the cheese layer. Sprinkle the shredded cheddar cheese on top of the beef layer.
- Mix the wet ingredients. In a mixing bowl, whisk together the eggs, milk, and cream of mushroom soup until well combined.
- Pour over the casserole. Carefully pour the egg mixture over the layers in the baking dish, allowing it to seep down between the sliders.
- Bake the casserole. Place the dish in the preheated oven and bake for 45-50 minutes, or until the casserole is set and lightly golden on top.
- Garnish and serve. Remove from the oven and let it cool for a few minutes. Garnish with freshly chopped parsley before serving.
