The Perfect Cheeseburger
Total Time: 50 minutes
Yields: 4 servings
1 small white onion, divided
2 Tbsp oil, divided
1/3 cup mayonnaise
1/3 cup ketchup
1 Tbsp chopped parsley
1 Tbsp relish
1 lemon, juiced
Salt and pepper
1-1/2 lb (675 g) medium ground beef
2 tsp Dijon mustard
8 slices processed cheese
4 burger buns
1 tomato, sliced
8 leaves Boston bibb lettuce
Additional condiments, as desired
1. Slice half the onion into thin rounds and set aside. Slice remaining onion into ½-inch thick strips.
2. Heat a cast iron skillet to high heat. Add 1 tbsp oil and onion strips. Cook until charred, about 5 minutes.
3. Chop onion and add to a small bowl. Stir in mayonnaise, ketchup, parsley, relish, lemon juice and salt and pepper, to taste. Set aside.
4. Meanwhile, mix ground beef with mustard. Divide into eight, 3 oz portions and place one patty on a plate with a square of waxed paper brushed lightly with a bit of the remaining oil. Flatten the patty to ¼-inch thickness with another plate. Season liberally with salt and pepper. Repeat with remaining beef portions.
5. Heat a large cast iron skillet or griddle to high heat. Working in batches, place patties onto pan and cook until dark golden, about 90 seconds per side. After flipping, place cheese onto each patty until melted.
6. Spoon about half of the prepared sauce onto the four bottom buns. Top evenly with lettuce, tomatoes, onion rounds, two burger patties and any additional condiments. Spread bun tops evenly with remaining sauce and place over burgers.
