Prepare the Beef Patties:

1. Preheat the Oven: Preheat your oven to 375°F (190°C).
2. Season the Beef: In a mixing bowl, combine the ground beef with Worcestershire sauce, salt, and pepper. Mix until just combined—be careful not to overwork the meat.
3. Form the Patties: Divide the beef mixture into 12 equal portions and shape each portion into a small patty that fits the slider buns. Place the patties on a baking sheet lined with parchment paper.

Cook the Sliders:

4. Cook the Patties: Heat a skillet over medium-high heat and add olive oil. Cook the patties in batches, about 3-4 minutes per side, until browned and cooked through (internal temperature should reach 160°F or 71°C). Alternatively, you can cook the patties in the oven for 12-15 minutes.
5. Add the Cheese: In the last minute of cooking, top each patty with a slice of cheese. Cover with a lid to help the cheese melt evenly.

Assemble the Sliders:

6. Prepare the Buns: While the patties are cooking, slice the slider buns in half horizontally. Brush the top of each bun with melted butter and sprinkle with sesame seeds if desired.
7. Assemble the Sliders: Once the patties are cooked and the cheese is melted, place each patty on the bottom half of the buns. Add your favorite toppings like lettuce, tomato, pickles, and condiments. Top with the other half of the bun.

Serve the Sliders:

8. Serve Immediately: Serve the sliders hot, either on a platter or as individual sandwiches. They are great for serving with fries, onion rings, or a side salad.
