Keto Big Mac Casserole

Preheat your oven to 350°F (175°C).
In a large skillet over medium heat, cook the ground beef until browned. Drain any excess fat.
Add the diced onion and minced garlic to the skillet. Cook until the onion is translucent.
Stir in the chopped pickles and 1 cup of the shredded cheddar cheese. Mix well and spread the mixture evenly in a greased baking dish.
In a bowl, whisk together the eggs, heavy cream, mayonnaise, mustard, Worcestershire sauce, sugar-free ketchup, salt, and pepper.
Pour the egg mixture over the beef mixture in the baking dish. Sprinkle the remaining 1 cup of shredded cheddar cheese on top.
Bake in the preheated oven for 30-35 minutes, or until the casserole is set and the cheese is bubbly and golden.
While the casserole is baking, prepare the Keto Big Mac Sauce. In a small bowl, combine mayonnaise, dill pickle relish, mustard, sugar-free ketchup, white vinegar, onion powder, garlic powder, salt, and pepper. Mix until well combined.
Once the casserole is done baking, remove it from the oven and let it cool slightly.
Top the casserole with shredded lettuce, diced tomatoes, and sliced pickles.
Drizzle the Keto Big Mac Sauce over the top of the casserole.
Serve immediately and enjoy your delicious keto Big Mac casserole!
