Combine ground beef, salt, and black pepper in a mixing bowl and gently mix until just combined. Form the mixture into four small, evenly-sized patties, about 2-3 inches in diameter.
1 lb ground beef, 1 tsp salt, 0.5 tsp black pepper
Preheat the grill to medium-high heat. Carefully place the patties onto the grill, placing them with the uncooked side down first. Let cook without moving for about 3-4 minutes until the bottom develops a deep golden-brown, crispy crust and the juices start to pool on top.

Use a spatula to flip each patty gently and continue grilling for another 3-4 minutes, until the second side is also browned and the burger is cooked to desired doneness. The bottom should be crispy and caramelized, providing a crunchy texture.

Remove the patties from the grill and let rest for 2 minutes. Lightly toast the slider buns on the grill for about 1 minute until golden brown.
4 small slider buns
Assemble the sliders by placing each crispy-bottom patty onto a toasted bun, adding optional toppings if desired, and covering with the top bun. Serve immediately to enjoy the contrast of the crunchy crust and tender interior.
