The Essential Ingredients
The beauty of this Keto Pizza Casserole lies in its simplicity. You only need a few core ingredients to create a rich and flavorful base.
For the Casserole Base:
- Ground Beef: I prefer 80/20 ground chuck for its flavor and juiciness, but ground turkey or Italian sausage also work wonderfully.
- Onion & Garlic: These aromatics build the foundational layer of flavor.
- Sugar-Free Marinara Sauce: Be sure to check the label! Many store-bought sauces contain hidden sugars. Rao’s Homemade is a popular and reliable keto-friendly option.
- Cream Cheese: This is the secret ingredient that adds a wonderful creaminess and richness to the base layer, almost like a savory crust.
- Seasoning: A blend of dried oregano, basil (or just Italian seasoning), salt, and pepper is all you need.
For the Toppings:
- Mozzarella Cheese: Freshly shredded mozzarella melts better than pre-shredded varieties, which often contain anti-caking agents.
- Pepperoni Slices: A pizza classic! Use your favorite kind.
- Optional Toppings: Sliced black olives, bell peppers, or sautéed mushrooms are fantastic additions. For a similar vibe, check out this delicious sautéed zucchini and mushrooms recipe that you could serve on the side.
How to Make Keto Pizza Casserole Step-by-Step
Making this pizza bake is as simple as browning the meat and layering the ingredients. Follow these easy steps for a perfect result every time.
- Preheat and Prep: Start by preheating your oven to 375°F (190°C) and lightly greasing a 9×13 inch baking dish.
- Brown the Beef: In a large skillet over medium-high heat, cook the ground beef with the chopped onion until the beef is browned and the onion is soft. Drain off any excess grease.
- Create the Creamy Base: Reduce the heat to low and stir in the minced garlic, cream cheese, half of the marinara sauce, and all the seasonings. Continue stirring until the cream cheese is fully melted and integrated, creating a creamy meat sauce.
- Assemble the Casserole: Spread the meat mixture evenly into the bottom of your prepared baking dish. Top it with the remaining marinara sauce. Sprinkle the shredded mozzarella cheese evenly over the top.
- Add Toppings and Bake: Arrange the pepperoni slices and any other desired toppings over the cheese. Bake for 20-25 minutes, or until the casserole is bubbly and the cheese is melted and slightly golden. For a crispier pepperoni topping, you can switch to the broiler for the last 1-2 minutes, but watch it closely to prevent burning!
Pro Tips for the Perfect Pizza Bake
Want to ensure your casserole is absolutely perfect? Here are a few tips from a seasoned culinary guide.
- Drain the Grease Thoroughly: To avoid a greasy or watery casserole, make sure you drain the ground beef completely after browning.
- Shred Your Own Cheese: Pre-shredded cheese contains starches that can prevent it from melting smoothly. For the best gooey cheese pull, buy a block of mozzarella and shred it yourself.
- Don’t Overbake: The casserole is done as soon as it’s heated through and the cheese is melted. Overbaking can make the cheese tough.
Fun Variations to Try
One of the best things about this recipe is how easy it is to customize. Think of it as a blank canvas for your favorite pizza flavors!
- Supreme Pizza Casserole: Add cooked Italian sausage, sautéed bell peppers, onions, and black olives.
- Meat Lover’s Dream: Combine ground beef with cooked Italian sausage and bacon crumbles.
- Veggie-Loaded: For more nutrients, mix in some cooked spinach or zucchini with the ground beef. If you enjoy keto casseroles with ground beef, you might also love our popular Keto Ground Beef Casserole.
What to Serve With Your Casserole
This Keto Pizza Casserole is a complete meal on its own, but it also pairs wonderfully with a simple side dish. A fresh Caesar salad (hold the croutons!), steamed green beans, or roasted broccoli are all excellent low-carb options that complement the rich flavors of the casserole.
Storing and Reheating Leftovers
Leftovers are one of the best parts of this dish! Store any remaining casserole in an airtight container in the refrigerator for up to 4 days.
To reheat, you can microwave individual portions for 1-2 minutes or place the entire baking dish back in a 350°F oven until heated through. The flavors often meld together and taste even better the next day!
Frequently Asked Questions
Yes, this is a great make-ahead meal! You can assemble the entire casserole, cover it tightly, and store it in the refrigerator for up to 24 hours before baking. You may need to add 5-10 minutes to the baking time if it’s going into the oven straight from the fridge.
The key to preventing a watery casserole is to thoroughly drain the excess grease from the ground beef after browning. Also, if you add vegetables like mushrooms or zucchini, it’s best to sauté them first to cook out their excess moisture before adding them to the casserole.

Ingredients
Equipment
Method
- Preheat your oven to 375°F (190°C). Lightly grease a 9x13 inch baking dish.
- In a large skillet over medium-high heat, cook the ground beef and chopped onion until the beef is fully browned. Drain all excess grease from the skillet.
- Reduce the heat to low. Add the minced garlic, softened cream cheese, 1/2 cup of the marinara sauce, oregano, basil, salt, and pepper to the skillet. Stir continuously until the cream cheese has melted completely and the sauce is creamy.
- Transfer the meat mixture to the prepared baking dish and spread it into an even layer. Pour the remaining 1 cup of marinara sauce over the top.
- Sprinkle the shredded mozzarella cheese evenly over the sauce. Arrange the pepperoni slices on top. Bake for 20-25 minutes, until the cheese is melted and bubbly. For crispier pepperoni, broil for 1-2 minutes at the end, watching carefully.
- Let the casserole rest for 5-10 minutes before serving. This allows it to set and makes for cleaner slices.
Notes
Tip 2: Ensure you are using a sugar-free marinara sauce to keep the recipe keto-friendly. Check the nutrition label for hidden sugars.
Tip 3: Feel free to add other low-carb pizza toppings like cooked mushrooms, black olives, or bell peppers.
