Ingredients
Method
Prepare the Sauce
- Mix together mayo, ketchup, sweet relish, vinegar, sugar, and a pinch of salt and pepper. Taste and adjust if necessary. Chill while cooking.
Prepare the Toppings
- Slice lettuce, tomatoes, pickles, and onions. Set aside for assembly.
Form and Cook Patties
- Divide beef into 2 to 4 ounce portions. Roll lightly and then press into thin rounds.
- Heat a cast iron skillet over medium-high heat until hot.
- Butter the cut sides of the buns and toast them until golden, then set them aside.
- Season one side of each patty with salt and pepper, then cook the patties in the hot skillet for about 2 minutes.
- Flip the patties, add a slice of cheese, and cook for an additional 1 to 2 minutes.
- If desired, grill onions until soft and browned, or slice them raw.
Assemble the Burgers
- Layer the burgers with the bottom bun, sauce, lettuce, tomato, patty with cheese, onions, and pickles, finishing with more sauce and the top bun.
Notes
For a lighter option, replace the bun with lettuce wraps. Serve immediately for the best taste and texture.
