Ingredients You’ll Need
To make this delicious casserole, you’ll need a mix of pantry staples and fresh ingredients. Each one plays an important role in building that signature cheeseburger flavor.
For the Beef Layer:
- 1 pound ground beef
- 1 cup chopped onion
- 2 cloves garlic, minced
- 1 teaspoon Worcestershire sauce
- 1 teaspoon burger seasoning
- Salt and pepper to taste
- 2 ounces cream cheese
For the Creamy Egg Mixture:
- 2 large eggs
- ½ cup heavy whipping cream
- 1–2 teaspoons mustard (adjust to taste)
- ½ cup shredded cheddar cheese
- ½ cup shredded white cheddar cheese
Toppings:
- 3 slices bacon, cooked and crumbled
- 1 kosher pickle, sliced
- ½ cup shredded cheddar cheese (for topping)
- ½ cup shredded white cheddar cheese (for topping)
Step-by-Step Instructions
Step 1: Preheat the Oven
Start by preheating your oven to 350°F (175°C). This ensures even cooking and helps the cheese melt perfectly into a bubbly, golden topping.
Step 2: Cook the Beef Mixture
In a large skillet over medium heat, add the ground beef. As it begins to cook, add the chopped onion, minced garlic, burger seasoning, salt, and pepper.
Use a spatula to break the beef into small crumbles as it cooks. Continue cooking until the beef is browned and no longer pink.
Next, stir in the Worcestershire sauce and cream cheese. Allow the cream cheese to melt completely, stirring until everything is well combined and creamy. Once done, remove the skillet from heat.
Step 3: Prepare the Egg Mixture
In a medium mixing bowl, whisk together the eggs, heavy cream, mustard, and both types of shredded cheese. This mixture will act as a rich, custard-like layer that binds the casserole together.
Step 4: Assemble the Casserole
Lightly grease an 8×11-inch or 9×9-inch baking dish with cooking spray or oil.
Spread the cooked beef mixture evenly across the bottom of the dish. Then sprinkle the crumbled bacon and sliced pickles over the top. These add that classic bacon cheeseburger flavor and a slight tangy crunch.
Pour the egg and cheese mixture evenly over the beef layer, making sure it spreads across the entire dish.
Step 5: Add the Cheese Topping
Sprinkle the remaining shredded cheddar and white cheddar cheese over the top. This will create a beautifully melted, golden crust once baked.
Step 6: Bake
Place the casserole in the preheated oven and bake for 15–20 minutes, or until the cheese is fully melted and bubbling.
Step 7: Cool and Serve
Remove the casserole from the oven and let it cool for a few minutes before slicing. This helps the layers set and makes serving easier.
Serve warm and enjoy every cheesy, savory bite!
Tips for the Best Results
To make sure your casserole turns out perfect every time, keep these helpful tips in mind:
Use high-quality ground beef for the best flavor. An 80/20 blend works well because it provides enough fat to keep the dish juicy without being overly greasy.
Don’t skip the cream cheese—it adds richness and helps create that signature creamy texture.
Adjust the mustard to your preference. If you love a tangy burger flavor, add a bit more. If you prefer a milder taste, stick to one teaspoon.
Let the casserole rest before cutting. This helps everything firm up and prevents it from falling apart when serving.
Variations and Customizations
One of the best things about this recipe is how easy it is to customize. Here are a few ideas to switch things up:
If you like a bit of spice, add diced jalapeños or a pinch of red pepper flakes to the beef mixture.
For a more “loaded burger” feel, top the casserole with chopped lettuce and tomatoes after baking.
You can swap ground beef for ground turkey or chicken if you prefer a lighter option.
Add mushrooms or bell peppers to the beef mixture for extra flavor and texture.
If you love extra cheese, try mixing in mozzarella or pepper jack for a different twist.
Serving Suggestions
This keto bacon cheeseburger casserole is satisfying on its own, but you can pair it with a few simple sides to complete the meal:
Serve it with a fresh green salad for a light and refreshing contrast.
Add a side of roasted vegetables like zucchini or broccoli for extra nutrients.
If you’re not strictly keto, a slice of toasted bread or bun on the side can turn it into a full burger-style experience.
Storage and Reheating
This casserole stores beautifully, making it perfect for meal prep.
Allow leftovers to cool completely before transferring them to an airtight container. Store in the refrigerator for up to 3–4 days.
To reheat, simply warm a portion in the microwave for 1–2 minutes or in the oven at 300°F (150°C) until heated through.
You can also freeze this casserole for longer storage. Wrap it tightly and freeze for up to 2 months. Thaw overnight in the refrigerator before reheating.
