Ground beef
Onion (diced)
Garlic (minced)
Salt
Black pepper
Worcestershire sauce
Cream cheese
Eggs
Heavy cream
Shredded cheddar cheese
Mustard (optional)
Pickles (optional for topping)

Directions

I preheat the oven to 350°F (175°C).
In a skillet over medium heat, I cook the ground beef with diced onion and garlic until the beef is browned and the onions are soft. I drain any excess grease.
I stir in salt, pepper, Worcestershire sauce, and cream cheese. I cook until the cream cheese is melted and evenly mixed into the beef.
In a separate bowl, I whisk together the eggs, heavy cream, and mustard (if using).
I transfer the beef mixture into a greased 9x13-inch baking dish and spread it out evenly.
I pour the egg mixture over the beef and top it with shredded cheddar cheese.
I bake for 30–35 minutes, or until the casserole is set and the cheese is bubbly and slightly golden.
I let it rest for 5–10 minutes before slicing. I top it with chopped pickles if I want extra cheeseburger vibes.

Servings and timing

This recipe makes about 6 servings. It takes roughly 10 minutes to prep and 30–35 minutes to cook, so I have a hearty keto dinner on the table in about 45 minutes.

Variations

I add chopped jalapeños to the beef for extra flavor.
I swap cheddar for pepper jack or mozzarella depending on my mood.
I mix in chopped pickles or pickle relish to the filling for tang.
I make it spicy by adding a few dashes of hot sauce or red pepper flakes.

Storage/Reheating

I store leftovers in an airtight container in the fridge for up to 4 days. It reheats well in the microwave or oven. For meal prep, I slice the casserole into portions and store them separately for easy grab-and-go lunches. It also freezes well—I just thaw and reheat when needed.

FAQs

Can I make this casserole ahead of time?

Yes, I assemble it ahead and store it covered in the fridge for up to a day. I bake it fresh when ready to serve.

What kind of ground meat can I use?

Ground turkey or chicken both work well—I just adjust seasoning as needed since they’re milder than beef.

Can I use milk instead of cream?

I prefer heavy cream for its richness and fat content, but unsweetened almond milk or half-and-half can work if I’m watching calories.

How do I keep it from being watery?

I make sure to fully cook and drain the beef mixture before baking, and avoid overdoing the veggies or toppings that release moisture.

Can I freeze the leftovers?

Yes, I freeze individual portions wrapped well or stored in containers. They keep for up to 2 months and reheat well in the microwave or oven.

Conclusion

Keto Cheeseburger Casserole is everything I want in a low-carb dinner—meaty, cheesy, easy, and incredibly satisfying. It’s a staple in my weekly rotation and a great way to enjoy classic burger flavor without the bun. Whether I’m cooking for the family or meal prepping for myself, this casserole always hits the spot.
