Creating the delicious Low-Carb Bacon Cheeseburger Casserole is easier than you might think. Follow these straightforward steps to achieve perfect results:

1. Preheat Oven: Preheat your oven to 350°F (175°C).
2. Cook Bacon: In a large skillet over medium heat, cook the chopped bacon until crispy. Remove and drain on paper towels.
3. Brown the Beef: In the same skillet, drain excess bacon grease, leaving about 1 tablespoon. Add diced onion and minced garlic, sautéing until soft. Add the ground beef and cook until browned. Drain any excess fat.
4. Combine Ingredients: In a large mixing bowl, whisk together the eggs, heavy cream, mustard, salt, black pepper, and paprika until well combined. Stir in the cooked beef mixture, crispy bacon, and 1 cup of shredded cheese.
5. Prepare Casserole Dish: Grease a 9×13-inch casserole dish. Pour the beef and bacon mixture into the dish, spreading evenly.
6. Add Toppings: If using, sprinkle the diced tomatoes and sliced pickles over the top of the casserole.
7. Bake: Carefully place the casserole in the preheated oven and bake for 25-30 minutes, or until the eggs are set and the top is golden.
8. Add Remaining Cheese: About 5 minutes before removing from the oven, sprinkle the remaining cheddar cheese on top and allow it to melt.
9. Garnish: Remove from the oven, let cool for a few minutes, and garnish with fresh parsley before serving.

These easy steps will help you craft an incredible casserole that showcases all the flavors of a bacon cheeseburger in a deliciously satisfying form.
