01 - In a large bowl, gently combine the ground beef with salt, pepper, garlic powder, and onion powder. Do not overmix to maintain tender texture.
02 - Divide the mixture into 8 equal portions and shape each into a small, flat patty slightly larger than your buns to account for shrinkage during cooking.
03 - Heat the vegetable oil or butter in a large skillet or grill pan over medium-high heat until shimmering.
04 - Cook the patties for 2-3 minutes per side, or until browned and cooked to your desired doneness.
05 - In the last minute of cooking, place a slice of cheddar cheese on each patty and cover the pan to help it melt completely.
06 - Split and lightly toast the slider buns for added texture and to prevent sogginess.
07 - Spread mayonnaise and ketchup on each bun, add the cheesy beef patty, and top with onion, pickles, tomato, and lettuce as desired.
08 - Serve immediately while hot for best flavor and texture.
