Preheat your grill or skillet over medium-high heat. Shape the ground beef into four evenly sized patties, pressing slightly to create a gentle indentation in the center of each to prevent curling. Season with salt and pepper if desired.
Place the patties on the hot grill or skillet. Cook for about 4-5 minutes per side, until the edges are golden brown and the patties are cooked through, with juices running clear. During the last minute, top each patty with a slice of cheddar cheese to melt.
While the patties cook, split the burger buns and lightly toast the insides, either on the grill or in a toaster, until they’re just golden. This adds a slight crunch and prevents sogginess.
Arrange your spooky toppings in small bowls to make adding features easier. Prepare the googly eyes, sliced peppers, olives, and tomatoes to create facial details for each burger.
Once the patties are cooked and cheese is melted, transfer them to a plate to rest briefly. Carefully place a burger patty onto the bottom half of each toasted bun.
Use slices of cheddar or other toppings to craft fun monster faces—add googly eyes, slices of peppers for mouths, or olives for spooky accents—pressing them gently into the cheese and burger to stay in place.
Decorate your monsters further with condiments, like small dabs of ketchup or mustard for fiendish mouths or scars. Top your creations with the upper halves of the buns, pressing down lightly to secure the toppings.
Arrange each assembled Monster Burger on a serving plate. Add extra toppings, such as cherry tomatoes or sliced peppers, around for a creepy effect or colorful garnish.
Serve immediately, allowing everyone to enjoy the playful, monster-faced burgers with their crispy edges and gooey melted cheese. Encourage fun storytelling as part of the meal!
