Divide beef into 4 equal patties, each about 1 inch wider than your buns. Press a shallow indent in the center of each patty, then season both sides generously with salt and pepper.
Heat a cast-iron skillet or grill over medium-high heat until very hot. Cook patties undisturbed for 6 minutes until a crust forms. Flip, brush with melted butter, and cook another 3 minutes. Top each patty with a slice of cheese, then cook 3 more minutes for medium doneness.
Meanwhile, combine mayonnaise, mustard, pickle juice, and paprika in a small bowl. Season with pepper.
Assemble burgers: Spread sauce on bottom buns, add lettuce, tomato, burger patty, onion, and pickles. Spread more sauce on top buns, close, and serve.
