Ingredients
Scale
Beef Patty and Toppings
- 1 lb ground beef (80% lean)
- 1 small onion, finely chopped
- 6 slices American cheese, cut in half (optional)
- Salt and pepper to taste
- 1 tablespoon mustard (optional)
- 1 tablespoon ketchup (optional)
Buns
- 12 small slider buns (such as Kings Hawaiian or similar soft buns)
- 1 tablespoon butter (for toasting buns)
Instructions
- Preheat the oven: Set your oven to 350°F (175°C) to prepare for toasting the slider buns.
- Caramelize the onions: Heat a large skillet over medium heat with a little oil or butter. Add the finely chopped onion and cook for 10-15 minutes, stirring occasionally, until the onions are softened and golden brown. Remove from heat and set aside.
- Toast the slider buns: Arrange the slider buns on a baking sheet and place them in the preheated oven. Toast them lightly for about 5 minutes until they turn slightly golden and are warmed through.
- Form the beef patty: Shape the ground beef into one large, even patty approximately the size of your baking sheet. Season generously with salt and pepper on both sides.
- Cook the beef patty: Heat a large skillet or griddle over medium heat. Place the beef patty onto the skillet and cook for 4-5 minutes per side, until it’s well browned and cooked through. Make sure the inside is no longer pink.
- Cut the patty into squares: Once the large patty is cooked, transfer it to a cutting board and carefully cut it into 12 small squares, sized to fit the slider buns.
- Assemble the sliders: Place each beef square on the toasted buns. Top each with a spoonful of caramelized onions and a half-slice of American cheese, if using. Add mustard and/or ketchup as desired for extra flavor.
- Serve immediately: Enjoy the sliders hot and fresh for the best taste and texture.
Notes
- You can substitute the slider buns with any soft small buns or dinner rolls you prefer.
- For extra flavor, try adding pickles or a dash of Worcestershire sauce to the beef before cooking.
- Make sure not to overcook the beef patty to keep the sliders juicy.
- If you prefer, you can toast the buns in a skillet with butter instead of the oven.
- These sliders are best served fresh but can be kept warm in a low oven for a short time if preparing for a party.
