Step 1: Preheat the Oven
- Preheat your oven to 400°F.
Step 2: Prepare the Burger Layer
- In a 9x13 baking dish, spread about 1 tablespoon of yellow mustard across the bottom.
- Add: 1½ pounds ground beef
- 1 tablespoon garlic salt
- Cracked black pepper to taste
- Mix gently and press the beef evenly into the baking dish to form one large burger patty.
- Sprinkle half of the chopped onions over the top.
Step 3: Bake the Burger
- Bake for 20-25 minutes, or until the beef is fully cooked.
- Tip: If using frozen Stouffer's mac and cheese, start heating it now so it's ready when the burger comes out of the oven.
Step 4: Prepare the Slider Base
- While the burger bakes, slice the King's Hawaiian rolls in half horizontally.
- Place the bottom half of the rolls into a second 9x13 baking dish.
- Layer the bottom rolls with:
- Cheddar cheese slices
- Remaining chopped onions
Step 5: Transfer the Burger
- Carefully lift the cooked burger patty from the first baking dish and place it directly on top of the cheese, pickles, and onions.
Step 6: Add the Mac and Cheese
- Spread the prepared mac and cheese evenly over the burger layer.
- Top with shredded cheddar cheese.
Step 7: Make the Burger Sauce
- In a small bowl, combine ketchup and mayonnaise.
- Spread the sauce onto the cut side of the top half of the slider buns.
- Place the top buns over the sliders.
Step 8: Make the Butter Topping
- In a small bowl, whisk together:
- ½ tablespoon melted butter
- 1 teaspoon Worcestershire sauce
- 1 teaspoon garlic powder
- Pinch of salt
- Pinch of black pepper
- Brush generously over the tops of the rolls.
Step 9: Final Bake
- Cover the sliders with foil and bake for 10 minutes.
- Remove the foil and bake for an additional 10 minutes, or until the tops are golden brown and the cheese is melted.
Step 10: Serve
- Slice into sliders and serve with extra ketchup and mayonnaise mixed together for dipping.
