How to Make Keto Bacon Cheeseburger Casserole – Step By Step
Step 1 – Prepare the Beef Mixture
In a large skillet, brown the ground beef over medium heat. As it cooks, break the beef into crumbles. Once browned, add in the chopped onion and minced garlic. Stir until the onion becomes translucent and the garlic releases its aroma. Drain any excess fat from the skillet.
Step 2 – Cook the Bacon
While the beef is cooking, prepare the bacon by frying, baking, or microwaving it until crispy. Once done, crumble it into small pieces. This will serve as a delightful topping for your casserole.
Step 3 – Mix the Liquid Ingredients
In a mixing bowl, combine the eggs, heavy cream, mustard, Worcestershire sauce, salt, and black pepper. Whisk these ingredients together until they are fully blended. This is your custard base that will hold the casserole together when baked.
Step 4 – Assemble the Casserole
Preheat the oven to 350°F (175°C). In your baking dish, spread the cooked beef mixture evenly at the bottom. Sprinkle half of the shredded cheddar on top. Pour the custard mixture over the beef, ensuring even coverage. Add the remaining cheese on top and finish with the crumbled bacon.
Step 5 – Bake
Place the dish in the preheated oven and bake for about 30 minutes, or until the cheese is bubbly and golden. Let it cool for a few minutes before serving to allow the casserole to set properly.

Recipe Success Tips & Suggestions
When cooking the beef, ensure it’s fully crumbled for a uniform texture in the casserole. Don’t skip draining excess fat to prevent a greasy dish. Feel free to customize your casserole with additional ingredients such as chopped pickles or jalapeños for extra flavor.
