Creating the Low-Carb Bacon Cheeseburger Casserole is straightforward. Just follow these steps:

1. Preheat the Oven: Set your oven to 350°F (175°C).
2. Cook Bacon: In a skillet over medium heat, cook the chopped bacon until crispy. Remove the bacon with a slotted spoon and drain on paper towels.
3. Cook Ground Beef: In the bacon drippings, add the diced onion and minced garlic. Sauté until softened, about 3-4 minutes.
4. Add Ground Beef: Add the ground beef to the skillet, breaking it apart and cooking until browned. Season with salt and pepper to taste.
5. Combine Ingredients: In a bowl, whisk together the heavy cream, eggs, Worcestershire sauce, and Dijon mustard if using.
6. Layer the Casserole: In a greased baking dish, layer the cooked ground beef mixture, followed by the crispy bacon, and then sprinkle shredded cheddar cheese on top.
7. Pour Cream Mixture: Pour the cream and egg mixture evenly over the layers in the baking dish.
8. Bake: Place the dish in the preheated oven and bake for 30-35 minutes, or until set and golden brown on top.
9. Cool: Allow the casserole to cool for a few minutes before serving.
10. Add Pickles: If desired, top with chopped pickles for added flavor and crunch.
