  • 1 lb. lean ground beef
  • ¼ cup sweet onion, grated
  • 1 tsp. salt
  • ¼ tsp. black pepper, to taste
  • 3 Tbsp. canola oil
  • ½ cup mayonnaise
  • 1 Tbsp. ketchup
  • 1 Tbsp Dijon mustard
  • ½ tsp celery salt
  • ½ tsp onion powder
  • ¼ tsp garlic powder
  • 4 slices American cheese slices
  • 4 hamburger buns
  • 1 ½ Tbsp butter
  • 1 cup iceberg lettuce, shredded
  • 2 XL Beefsteak tomatoes, sliced
  • 4 dill pickles


  • In a large bowl, combine ground beef, onion, salt and pepper, mix until just combined. Do not overmix. Shape into four, 4-ounce balls and set aside.
  • In a small bowl, mix the mayonnaise, ketchup, mustard, celery salt, onion and garlic powder. Set aside.
  • Heat a cast iron skillet over high heat, until smoking. Add 2 Tbsp. oil and 2 meatballs, flattening immediately to ¼ “inch thickness with a sturdy wide spatula. Cook until the bottoms are crisp and dark brown, about 1-2 minutes. Flip patties and add a slice of cheese on each patty and place a lid on top for 1 minute. Once the cheese has melted, remove the patties and keep them warm by covering with foil. Repeat with the remaining meatballs and cheese slices.
  • Heat the broiler to high and toast the buns. Remove and spread with butter.
  • Spread each bottom and top half of the bun with the mayonnaise sauce. Add shredded lettuce to the bottom, then a slice of XL Beefsteak tomato, the beef patty, another slice of XL Beefsteak tomato, pickles and the top bun. Serve immediately.
