Form the Patties: Divide the ground beef into 4 equal portions and gently shape into patties about ¾ inch thick. Avoid overworking the meat.
Season: Sprinkle both sides of each patty with salt and freshly ground black pepper.
Cook the Patties: Preheat a skillet or grill to high heat. Cook the patties 3–4 minutes per side to achieve a dark, seared crust.
Add Blue Cheese: In the last minute of cooking, sprinkle crumbled blue cheese on top of each patty. Cover lightly to let the cheese melt slightly.
Toast the Buns: Butter and toast the buns lightly on the grill or skillet until golden brown.
Assemble the Burger: Place the cooked patty on the bun and add optional toppings as desired. Serve immediately while warm.
