How to Make Keto Cheeseburger Casserole

Step 1: Preheat the Oven

Preheat your oven to 375°F (190°C).

Grease a 9×13-inch baking dish.

Step 2: Cook the Beef

Heat olive oil in a large skillet.

Cook the diced onion until softened.

Add garlic and cook for about 30 seconds.

Stir in the ground beef and cook until browned.

Drain excess fat if necessary.

Season with:

• Salt
• Pepper
• Paprika
• Garlic powder
• Onion powder

Mix in the Worcestershire sauce and Dijon mustard.

Step 3: Prepare the Creamy Mixture

In a medium bowl, whisk together:

• Cream cheese
• Heavy cream
• Eggs

Blend until smooth.

Fold in half of the shredded cheddar cheese.

Step 4: Assemble the Casserole

Spread the cooked beef mixture evenly into the baking dish.

Pour the creamy cheese mixture over the beef.

Sprinkle the remaining cheddar and mozzarella evenly across the top.

Step 5: Bake

Bake for 20–25 minutes, or until the cheese is melted, bubbling, and lightly golden.

Allow the casserole to rest for 5–10 minutes before serving.

Best Cheese for Cheeseburger Casserole

Cheese is one of the stars of this recipe. While sharp cheddar provides the classic cheeseburger flavor, combining cheeses creates even more depth.

Great options include:
