Ingredients You’ll Need

• 2 garlic cloves – minced for aroma and depth
• ½ teaspoon onion powder – a subtle savory boost
• 1 pound sugar-free bacon, cooked and chopped – adds crispiness and smoky flavor
• 6 eggs – help hold the casserole together and create a creamy texture
• 6 ounces tomato paste – adds tangy richness without extra carbs
• 1 cup heavy cream – for a velvety, rich egg mixture

Tips for the Perfect Bacon Cheeseburger Casserole

Making this casserole is easier than you think. Here are some tips to make it truly delicious:

1. Pre-bake the bacon: Cooking bacon in the oven gives perfect crispiness without the mess of frying.
2. Freshly grate the cheese: Pre-shredded cheese often contains hidden starches, so grating it yourself keeps the carbs low.
3. Add cheese to the egg mixture: Mixing cheese into the egg base ensures it melts perfectly with the beef for a creamy consistency.
4. Make it dairy-free: Swap heavy cream for unsweetened almond or coconut milk and use a dairy-free cheese.
5. Customize your toppings: Avocado slices, jalapeños, or sugar-free ketchup make this casserole your own.

With these tips, your casserole will come out perfectly every time—creamy, cheesy, and packed with flavor.

How to Make Keto Cheeseburger Casserole

Making this keto bacon cheeseburger casserole is straightforward and quick. Follow these simple steps for a perfect, cheesy dish:

1. Cook the bacon: Chop the bacon and cook in a skillet until crispy. Remove from the pan and set aside, draining excess grease.
2. Brown the beef: In the same skillet, cook ground beef with minced garlic and onion powder over medium-high heat. Drain excess fat. Spread the cooked beef evenly in a cast-iron or oven-safe skillet.
3. Combine bacon and beef: Stir the crispy bacon pieces into the browned beef for a smoky, flavorful base.
4. Prepare the egg mixture: In a medium bowl, whisk together eggs, tomato paste, heavy cream, salt, and pepper until smooth. Stir in 8 ounces of grated cheddar cheese.
5. Assemble the casserole: Pour the egg-cheese mixture over the beef and bacon. Sprinkle the remaining 4 ounces of cheddar cheese on top.
6. Bake: Preheat oven to 350°F (175°C). Bake for 30-35 minutes or until the top is golden brown and the casserole is set.

Optional: Add mushrooms, onions, pickles, jalapeños, or pepper jack cheese to customize your casserole.
