I’ll be honest—when I first started eating keto, I missed casseroles the most. You know, those hearty, bubbling dishes you can throw together on a weeknight without much thought? Most casserole recipes rely on pasta or rice to bulk things up, which is a no-go when you’re watching carbs.
That’s why this keto ground beef casserole has become my go-to. It’s got all the comfort food vibes of a regular casserole, but without any of the stuff that’ll kick you out of ketosis. Just seasoned ground beef, cream cheese, and melted cheddar coming together in one pan. The best part? It only takes about ten ingredients, most of which you probably already have in your pantry.
Why You’ll Love This Ground Beef Casserole
- Keto-friendly – This casserole is perfect for low-carb eating with zero added carbs, just protein, cheese, and healthy fats to keep you satisfied.
- Ready in 30 minutes – From start to finish, you’ll have dinner on the table in half an hour, making it ideal for busy weeknights when you need something quick.
- Simple ingredients – Ground beef, cream cheese, cheddar, and basic spices are probably already in your kitchen, so no special shopping trip required.
- One-dish meal – Everything cooks together in one casserole dish, which means less cleanup and more time to relax after dinner.
- Family-approved – The creamy, cheesy beef is so good that even non-keto family members will ask for seconds without realizing it’s a low-carb meal.
What Kind of Ground Beef Should I Use?
For this keto casserole, you’ll want to pick a ground beef with the right fat content to keep things moist and flavorful. I recommend using 80/20 ground beef, which means it’s 80% lean meat and 20% fat – this gives you enough fat for flavor without making your casserole too greasy. If you prefer a leaner option, 85/15 will work too, though your casserole might be slightly less rich. Avoid anything leaner than 90/10, as it can make your dish dry and less satisfying. When you’re browning the beef, make sure to break it up into small, even crumbles so it cooks evenly and mixes well with the cheese and seasonings.
Options for Substitutions
This keto casserole is pretty forgiving when it comes to swaps:
- Ground beef: Ground turkey, ground chicken, or ground pork all work well here. Just keep in mind that leaner meats like turkey or chicken might need a bit more oil or butter to keep things moist.
- Cream cheese: You can use sour cream or Greek yogurt instead, though the texture will be slightly different. If using yogurt, add it at the end of cooking to prevent curdling.
- Cheddar cheese: Any melty cheese works great – try mozzarella, Monterey Jack, pepper jack for some heat, or a Mexican cheese blend. You can also mix different cheeses together.
- Spices: Feel free to adjust the spice blend to your taste. Skip the cayenne if you don’t like heat, or add some paprika or Italian seasoning for a different flavor profile.
- Parsley: Fresh or dried parsley both work, or you can swap it with cilantro, chives, or green onions for garnish.
Watch Out for These Mistakes While Cooking
The biggest mistake when making this keto casserole is not draining the ground beef properly after cooking, which can leave your dish swimming in grease and prevent the cheese from melting evenly – use a slotted spoon or press the beef against the side of the pan to remove excess fat.
Another common error is adding the cream cheese to beef that’s too hot, which can cause it to separate and become grainy instead of creamy, so let the meat cool for a minute or two after draining before stirring in the cream cheese.
To get a golden, bubbly cheese topping instead of just melted cheese, switch your oven to broil for the last 2-3 minutes of cooking, but watch it closely so it doesn’t burn.
Finally, don’t skip letting the casserole rest for 5 minutes after baking – this helps everything set up and makes serving much cleaner.
What to Serve With Ground Beef Casserole?
This hearty keto casserole is pretty filling on its own, but I love pairing it with a crisp side salad dressed with ranch or blue cheese dressing to balance out the richness. Roasted vegetables like broccoli, cauliflower, or Brussels sprouts are another great option that keeps things low-carb while adding some color to your plate. If you’re not strictly keto, some garlic bread on the side is always a crowd-pleaser for soaking up any cheesy goodness left in your bowl. You could also serve it with some sautéed green beans or zucchini noodles if you want to keep the meal lighter but still satisfying.
Storage Instructions
Store: This casserole is perfect for meal prep since it actually tastes even better the next day once all the flavors have melded together. Keep it covered in the fridge for up to 4 days, and just scoop out portions as you need them throughout the week.
Freeze: You can freeze this casserole for up to 3 months, either as a whole or in individual portions. I like to divide it into single servings in freezer-safe containers so I can grab one whenever I need a quick lunch or dinner.
Reheat: Warm it up in the microwave for 2-3 minutes, stirring halfway through, or pop it in a 350°F oven for about 15-20 minutes until heated through. If it seems a bit dry after reheating, just stir in a splash of heavy cream or a pat of butter to bring back that creamy texture.

Ingredients
- olive oil spray
- 2 lb ground beef
- 1.5 tsp salt
- 1/2 tsp black pepper
- 2.5 tsp garlic powder
- 1.5 tsp onion powder
- 1/4 tsp cayenne pepper
- 4 oz cream cheese (softened to room temperature)
- 1 cup cheddar cheese (shredded)
- 2 tbsp heavy cream
- 2 tbsp parsley (freshly chopped)
Step 1: Prepare and Season the Ground Beef
- olive oil spray
- 2 lb ground beef
- 1.5 tsp salt
- 1/2 tsp black pepper
- 2.5 tsp garlic powder
- 1.5 tsp onion powder
- 1/4 tsp cayenne pepper
Heat oven to 400°F.
While the oven preheats, spray a large skillet with olive oil and place over medium-high heat.
Add the ground beef and cook for 5 minutes, breaking it up with a wooden spoon as it cooks, until it’s mostly browned.
Drain off excess fat through a colander, then return the beef to the skillet.
Add the salt, black pepper, garlic powder, onion powder, and cayenne pepper, stirring well to distribute the seasonings evenly throughout the meat.
This creates a flavorful foundation for the casserole.
Step 2: Create the Creamy Cheese Base
- 4 oz cream cheese
- 2 tbsp heavy cream
- 1/2 cup cheddar cheese
Reduce heat to low and add the softened cream cheese to the seasoned beef, stirring constantly until it’s completely melted and evenly distributed throughout the meat.
The residual heat will melt the cream cheese without requiring additional cooking.
Add the heavy cream and stir until you have a creamy, cohesive mixture.
I like to let this mixture rest on the heat for about 1 minute so all the flavors meld together beautifully.
Stir in half of the shredded cheddar cheese (1/2 cup) until fully incorporated.
Step 3: Assemble and Bake the Casserole
- creamy beef mixture from Step 2
- 1/2 cup cheddar cheese
Transfer the creamy beef mixture from Step 2 into a 9×13 inch baking dish or similar size, spreading it evenly into an even layer.
Sprinkle the remaining 1/2 cup of cheddar cheese over the top.
Place the casserole in the preheated 400°F oven and bake for 10 minutes, until the cheese on top is melted and lightly golden.
I find that a quick bake at this higher temperature helps the cheese develop a slightly crispy texture while keeping the filling creamy inside.
Step 4: Finish and Serve
- 2 tbsp parsley
Remove the casserole from the oven and let it rest for 2 minutes before serving.
Sprinkle the fresh chopped parsley over the top as a garnish for color and a fresh flavor contrast to the rich, savory casserole.
