Large skillet

Mixing bowl
Whisk
Cheese grater

Ingredients

1 ½ pounds ground beef 680g
½ cup diced onion 75g
2 cloves garlic, minced
1 teaspoon sea salt
½ teaspoon ground black pepper
2 tablespoons Worcestershire sauce 30ml
1 tablespoon apple cider vinegar 15ml
1 cup shredded cheddar cheese 113g
1 cup shredded mozzarella cheese 113g
3 cups iceberg lettuce, shredded 210g
½ cup pickles, diced 75g
½ cup unsweetened dill pickle relish 120g
½ cup mayonnaise 120g
2 tablespoons sugar-free ketchup 30g
1 tablespoon mustard 15g
1 teaspoon white vinegar 5ml
1 teaspoon paprika
½ teaspoon onion powder
¼ teaspoon garlic powder

Instructions

Preheat your oven to 350°F (175°C).
In a large skillet over medium-high heat, brown the ground beef with the diced onion and minced garlic. Season with sea salt and black pepper. Cook until the beef is no longer pink and the onions are translucent. Drain excess fat.
Stir in Worcestershire sauce and apple cider vinegar to the beef mixture, and cook for an additional 2 minutes.
Transfer the beef mixture into a greased 9x13 inch baking dish.
In a small bowl, whisk together mayonnaise, sugar-free ketchup, mustard, white vinegar, paprika, onion powder, and garlic powder to create the Big Mac sauce.
Spread the sauce evenly over the beef mixture in the baking dish.
Sprinkle shredded cheddar and mozzarella cheese over the sauce layer.
Bake in the preheated oven for 20-25 minutes, or until the cheese is melted and bubbly.
While the casserole is baking, shred the iceberg lettuce and dice the pickles.
Once the casserole is done, let it cool for 5 minutes, then top with shredded lettuce and diced pickles.
Serve immediately, garnished with dill pickle relish.

Notes

For a spicier kick, add a dash of hot sauce to the Big Mac sauce.

If you prefer a crunchier topping, consider adding a sprinkle of crushed pork rinds on top before baking.

Leftovers can be stored in an airtight container in the refrigerator for up to 3 days. Reheat in the oven or microwave until warm throughout.
