Preheat your grill or skillet over medium-high heat until hot and slightly smoky.
Portion the ground beef into four equal-sized balls, then gently flatten them into patties about ¾ inch thick. Season both sides with salt and pepper.
Carefully place the patties onto the hot cooking surface. Cook for about 4-5 minutes per side, until they develop a browned, crispy exterior and are cooked through.
While the patties cook, prepare your toppings: slice tomatoes, shred lettuce, and set out cheese slices and spooky decorations like olives or peppers.
Once cooked, remove the patties from heat and let them rest for a minute to relax and lock in juices.
Toast the burger buns lightly, if desired, on the grill or in a toaster, to add a lightly crispy, warm base for each burger.
Assemble each monster burger by placing a beef patty on the bottom bun, then layer with cheese, lettuce, and tomato slices.
Decorate the burgers with spooky toppings to create monster features—use olives for eyes, peppers for mouths, or cheese slices for crazy hair.
Spread ketchup and mustard as desired, then top with the bun immediately before serving to keep the decorations intact.
Serve immediately, allowing everyone to enjoy the vibrant, spooky, and flavorful monster burgers.
