How To Make Grilled Onion Cheddar Burgers

Follow these simple steps to assemble flavorful burgers:

  1. Season the patties: Sprinkle both sides with salt, black pepper, garlic powder, and onion powder.
  2. Grill the patties: Cook over medium heat, flipping once until they reach your desired doneness. Alternatively, cook in a cast-iron skillet on the stovetop.
  3. Add cheese: Top each hot patty with a slice of white cheddar so it starts to melt as it rests.
  4. Grill the onions: Place onion rings on the grill and cook about 2–3 minutes per side until slightly charred and tender.
  5. Assemble and serve: Build burgers with meat, cheese, and onions on buns and serve immediately.

Substitutions and Variations

Make this recipe your own with these options:

  • Caramelized onions: Sauté onions slowly until deeply golden for extra sweetness instead of quickly grilling them.
  • Pickled onions: Add a tangy contrast by topping the burger with quick-pickled red onions.
  • Toasted buns: Lightly toast or grill buns to keep them crisp under condiments and to add texture.
  • Extra toppings: Try avocado, lettuce, grilled mushrooms, or pickles to customize each burger.
  • Smash burger method: Use a hot cast-iron skillet and press patties for thin, crispy edges if you prefer smash-style burgers.

Expert Tips For Grilled Burgers

  • Avoid overcooking: Watch the patties closely; overcooking will dry them out and cause juices to escape.
  • Preheat the grill or pan: A hot cooking surface gives a good sear and prevents sticking.
  • Handle meat gently: If you form patties at home, don’t overwork the meat to avoid dense, tough burgers.
  • No grill required: A grill pan or cast-iron skillet delivers great results indoors.

Recipe Frequently Asked Questions

What onion is best for grilled hamburgers?

White onions work well because they balance astringency and sweetness and take on a pleasant smoky flavor when grilled. Yellow, red, or sweet onions can also be used depending on your preference.

Should I put grilled or raw onions on my burger?

Both are fine. Grilled onions are softer and milder with a charred flavor, while raw onions add a crisp, pungent bite. Choose based on the texture and intensity you prefer.

What type of cheddar is best for burgers?

Mild or sharp white cheddar are great choices for melting and flavor. Extra-sharp cheddar can be used if you prefer a bolder taste that softens less. Shredded or sliced cheddar both work.

Grilled Onion Cheddar Burger

This burger is seasoned simply, topped with grilled onions and white cheddar, and cooks quickly on a grill or in a skillet.
Prep: 10
Cook: 10
Total: 20
Servings: 4 servings

Ingredients

  • 4 unseasoned burger patties 1 pound in total
  • ½ teaspoon salt
  • ¼ teaspoon ground black pepper
  • ½ teaspoon onion powder
  • ½ teaspoon garlic powder
  • 4-8 slices white cheddar cheese
  • 1 medium white onion cut into rings

Serving

  • 4 burger buns

Instructions

  • Preheat the grill or a grill pan to medium heat. Season both sides of the patties with salt, pepper, onion powder, and garlic powder.
  • Place the patties on the grill and cook 3–4 minutes on the first side. Flip and cook another 3 minutes, or until your preferred doneness. Remove from heat and top each patty with a slice or two of white cheddar.
  • Grill onion rings 2–3 minutes per side until tender and slightly charred.
  • Assemble burgers with the patties, melted cheese, and grilled onions on buns. Serve immediately.

Notes

  • Burger patties: Buy unseasoned patties or make your own from a pound of ground meat. When forming patties by hand, avoid overworking the meat to prevent toughness.
  • Watch cooking time: Burgers cook quickly—flip once and remove when they reach the desired doneness to retain juiciness.
  • Indoor option: If you don’t have an outdoor grill, a hot grill pan or cast-iron skillet works well.
