Making Low-Carb Bacon Cheeseburger Casserole is a breeze when you follow these easy steps:

1. Preheat Oven: Begin by preheating your oven to 350°F (175°C).
2. Cook Bacon: In a large skillet, cook the chopped bacon over medium heat until crispy. Remove and set aside, leaving the rendered fat in the skillet.
3. Brown Beef: In the same skillet, add the ground beef and diced onion. Cook until the beef is browned and the onion is soft. Drain excess grease if necessary.
4. Prepare Cauliflower: If using fresh cauliflower, steam or blanch it until tender. If using frozen, just thaw and drain.
5. Mix Ingredients: In a large bowl, combine the cooked beef mixture, cauliflower, cream cheese, beaten eggs, bacon (reserve some for topping), garlic powder, mustard, Worcestershire sauce, salt, and pepper. Mix until well combined.
6. Transfer to Baking Dish: Pour the mixture into a greased 9×13-inch baking dish, spreading it evenly.
7. Add Cheese: Sprinkle the shredded cheddar cheese on top, followed by the reserved bacon.
8. Bake: Place the casserole in the preheated oven and bake for 35-40 minutes until set and golden.
9. Cool and Serve: Allow it to cool slightly before cutting into squares for serving.

With these simple instructions, you’ll have a hearty and delicious casserole ready in no time!
