Ingredients

  • 1 1/2 pounds ground beef
  • Salt, to taste
  • Black pepper, to taste
  • 1 teaspoon garlic powder
  • 4 slices cheddar cheese
  • 1 cup shredded lettuce
  • 1/2 cup sliced pickles
  • 1/4 cup diced onions
  • 1/2 cup mayonnaise
  • 2 tablespoons sugar-free ketchup
  • 1 tablespoon mustard
  • 1 tablespoon pickle relish
  • 1 teaspoon white vinegar
  • 1/2 teaspoon paprika
  • 1/2 teaspoon onion powder

Instructions

  1. Divide the ground beef into equal portions and gently roll them into balls.
  2. In a small bowl, mix together the mayonnaise, sugar-free ketchup, mustard, pickle relish, white vinegar, paprika, and onion powder to make the sauce. Refrigerate until ready to use.
  3. Heat a skillet or griddle over medium-high heat.
  4. Place the beef balls onto the hot skillet and smash them flat using a spatula.
  5. Season the patties with salt, black pepper, and garlic powder.
  6. Cook for 2 to 3 minutes per side until the edges are crispy and browned.
  7. Top each patty with cheddar cheese during the final minute of cooking.
  8. Serve the burgers layered with shredded lettuce, sliced pickles, diced onions, and the homemade sauce.

Notes

  • Using 80/20 ground beef creates juicy burgers with crispy edges.
  • Lettuce leaves can be used as wraps for a handheld keto option.
  • Pepper jack cheese adds a spicy variation.
  • Sautéed mushrooms or jalapeños make great additional toppings.
  • The sauce can be prepared a day ahead for deeper flavor.
  • Store leftover patties in the refrigerator for up to 4 days.
  • Keep toppings and sauce separate until serving for the freshest texture.
