01 - Gently mix ground beef with salt, pepper, garlic powder, and onion powder in a bowl. Avoid overmixing to maintain tender texture.
02 - Divide mixture into 8 equal portions and shape into small patties, making them slightly wider than the buns to account for shrinkage during cooking.
03 - Heat grill or skillet over medium-high heat until hot.
04 - Cook patties for 2-3 minutes until browned on bottom. Flip, top each with cheddar slice, and cook another 2-3 minutes until cheese melts and patties reach desired doneness.
05 - Lightly toast slider buns on grill or in toaster until golden.
06 - Spread condiments on toasted buns. Layer lettuce, cheese-topped beef patty, tomato, pickles, and onion. Crown with top bun and serve immediately.
