How to Make the Low-Carb Bacon Cheeseburger Casserole
1. Prepare the Beef Layer
In a large skillet over medium heat, brown the ground beef. Add in the onion and garlic; sauté until softened. Season the mixture with salt, pepper, smoked paprika, and Worcestershire sauce. Drain any excess grease and set aside.
Shortcut Tip: Use onion and garlic powder if you’re short on time or want to skip chopping.
2. Make the Cheese Sauce
In a saucepan on low heat, combine the cream cheese and heavy cream. Stir until smooth and melted. Add cheddar cheese and mustard powder, stirring until the sauce is creamy and rich.
Pro Tip: Keep the heat low to prevent the sauce from separating.
3. Assemble the Casserole
Grease a 9×13-inch baking dish. Begin with:
Half of the beef mixture
Half of the marinara or diced tomatoes
Half of the cheese sauce
Sprinkle mozzarella
Repeat the layers, then finish with the remaining mozzarella, some extra shredded cheddar, and a generous sprinkle of chopped bacon on top.
4. Bake
Place in the preheated oven and bake uncovered for 20–25 minutes, until bubbly and golden on top.
5. Serve and Enjoy
Let it cool slightly before slicing. Garnish with fresh parsley if desired.
Storage Tips
Refrigerator: Store leftovers in an airtight container for up to 4 days. Reheat in the microwave or oven.
Freezer: You can freeze the fully baked casserole. Wrap tightly and freeze for up to 2 months. To reheat, let it thaw overnight in the fridge and then bake at 350°F for 15–20 minutes until hot.
