Description
These Caramelized Onion Beef Sliders are perfect for game day or a casual dinner. Juicy beef patties topped with sweet caramelized onions and melted provolone cheese, served on soft slider buns.
Ingredients
Scale
- 1 lb ground beef (80/20)
- 1 teaspoon salt
- 1/2 teaspoon black pepper
- 1 teaspoon garlic powder
- 1 teaspoon onion powder
- 2 tablespoons olive oil
- 3 large yellow onions, thinly sliced
- 2 tablespoons butter
- 1 tablespoon balsamic vinegar
- 1 teaspoon brown sugar
- 6 slider buns
- 6 slices provolone cheese
- Optional: mayonnaise, ketchup, or mustard for serving
Instructions
- 1. In a large skillet over medium heat, heat olive oil and butter. Add sliced onions and cook, stirring occasionally, for 20-25 minutes until deeply caramelized.
- 2. Stir in balsamic vinegar and brown sugar; cook for another 2 minutes. Remove from heat and set aside.
- 3. In a large bowl, combine ground beef, salt, pepper, garlic powder, and onion powder. Mix gently and divide into 6 equal portions; shape into small patties slightly larger than the buns.
- 4. Heat a grill or grill pan over medium-high heat. Cook patties for 3-4 minutes per side for medium doneness.
- 5. During the last minute of cooking, top each patty with a slice of provolone cheese; cover and cook until cheese melts.
- 6. Toast slider buns on the grill or in a toaster oven until lightly golden.
- 7. Assemble sliders: place a patty with cheese on the bottom bun, top with a generous spoonful of caramelized onions, and add the top bun. Serve immediately.
Notes
For extra flavor, you can add a thin spread of Dijon mustard or horseradish sauce to the buns. Leftover onions can be stored in the refrigerator for up to a week.
