- Ground beef brings a traditional cheeseburger vibe. For a leaner option, use ground chicken or turkey.
- Cheese - I love the combination of American and Cheddar. Monterey Jack, Pepper Jack, Swiss, or Provolone are also great options.
- Seasonings - Melted butter mixed with parsley and dried minced onion and garlic add another layer of flavor to the slider rolls.
See the recipe card for complete instructions and ingredient amounts.
- Preheat the oven to 375 degrees.
- In a large skillet, add the ground beef and onions. Brown the meat until it is cooked through, breaking it apart as it cooks. Drain the excess fat.
- Stir in ketchup, mustard, Worcestershire sauce, and salt and pepper. Simmer for 2-3 minutes.
- Meanwhile, melt the butter in a small saucepan. Stir in the minced onion, garlic, and parsley.
- To assemble, place the bottom half of the buns in a 9x13 baking dish. Brush the buns with the melted butter mixture.
- Top with the Cheddar cheese.
- Top with the beef mixture, spreading evenly.
- Layer the American cheese on top of the meat. Top with the pickles.
- Brush the inside of the top buns with the butter mixture. Place on top of the sliders. Brush the top of the buns with the remaining butter.
- Cover with foil and bake for 20-30 minutes until the cheese is melted.
- Serve with French fries, potato chips, or creamy coleslaw.
Storing and reheating
Store the sliders in an airtight container or wrap the casserole dish tightly with plastic wrap. These burgers will keep for 3-4 days.
To reheat: Wrap 1-2 sliders in a paper towel and microwave until warmed through. This method prevents the buns from drying out.
These sliders have a mixture of ketchup, yellow mustard, and Worcestershire sauce. The sauce is mixed into the meat - Sloppy Joe style - so every bite is packed with flavor.
This casserole can be assembled up to 1 day ahead of time. However, wait to brush the top of the buns with the butter mixture until just before baking.
The meat mixture can be made 2-3 days in advance. When ready to serve, assemble the casserole and bake according to the recipe directions.
