Preheat your grill or a skillet over medium-high heat, ensuring it is nice and hot before adding the patties.
In a mixing bowl, combine the ground beef, garlic powder, onion powder, salt, and black pepper. Gently mix with your hands until all ingredients are just integrated—be careful not to overwork the meat. Divide the mixture into 6 equal portions and shape each into a patty. Press a small indentation into the center of each patty using your thumb; this helps prevent them from puffing up as they cook.
Place the patties on the hot grill or skillet. Cook for approximately 3-4 minutes per side for a medium-rare finish. In the final minute of cooking, place a slice of cheddar cheese on each patty to allow it to melt beautifully.
While the burgers are cooking, slice the slider buns in half. Toast them lightly on the grill or in a skillet until they are golden brown and slightly crisp. This enhances flavor and provides structure to the sliders.
In a small bowl, whisk together the mayonnaise, ketchup, and yellow mustard until well blended to create a tangy sauce. Adjust seasoning if desired.
To assemble the sliders, spread a generous amount of the sauce on the bottom half of each toasted bun. Layer on a cheeseburger patty, a handful of shredded lettuce, a slice of fresh tomato, and a few dill pickle slices. Top each slider with the other half of the bun.
Serve the sliders immediately, paired with a side of crispy fries or a light salad for a delicious meal.
Notes
For optimal juiciness, use an 80/20 ground beef blend.
