Ingredients You’ll Need
The beauty of this keto pizza bake is its simplicity. You only need a handful of common ingredients to create a truly memorable meal.
For the Casserole Base
- Italian Sausage: Use one pound of ground Italian sausage (mild or hot) for a robust, savory foundation.
- Cream Cheese: Four ounces of full-fat cream cheese makes the base rich and creamy.
- Low-Carb Marinara Sauce: Choose a sauce with no added sugar to keep the carb count low. Rao’s Homemade is a great option.
- Seasoning: A simple mix of garlic powder, onion powder, and dried oregano enhances the classic pizza flavor.
For the Toppings
- Mozzarella Cheese: Two cups of shredded, whole-milk mozzarella for that essential cheesy pull.
- Pepperoni: Use about half a cup of your favorite pepperoni slices.
- Optional: Sliced black olives, mushrooms, or bell peppers for extra flavor and texture.
How to Make The Best Keto Pizza Casserole (Step-by-Step)
Follow these simple steps to create a flawless casserole every time. The key is to build layers of flavor, starting with a well-browned sausage base.
- Preheat and Prep: Start by preheating your oven to 375°F (190°C). Grease a 9×9 inch baking dish or a similar-sized casserole dish.
- Cook the Sausage: In a large skillet over medium-high heat, cook the Italian sausage until it’s browned and crumbled. Be sure to drain off any excess grease. This is a crucial step to prevent a watery casserole.
- Create the Base: Reduce the heat to low and stir in the softened cream cheese, marinara sauce, garlic powder, onion powder, and dried oregano. Continue stirring until the cream cheese is fully melted and the sauce is smooth and creamy.
- Assemble the Casserole: Pour the sausage mixture into your prepared baking dish and spread it into an even layer.
- Add Toppings: Sprinkle the shredded mozzarella cheese evenly over the top. Arrange the pepperoni slices and any other desired low-carb toppings over the cheese.
- Bake to Perfection: Bake for 20-25 minutes, or until the cheese is melted, bubbly, and slightly golden on top. Let it rest for 5-10 minutes before serving. This allows the casserole to set, making it easier to slice.
This dish is a fantastic alternative to traditional pizza, and you might find it even more satisfying. For another cheesy, family-friendly meal, check out our Cheesy Meatball Subs.
Expert Tips for a Perfect Low-Carb Pizza Bake
Want to elevate your casserole from good to great? Keep these simple tips in mind.
- Drain Everything: The number one rule for a perfect casserole is to remove excess moisture. Thoroughly drain the cooked sausage. If you add vegetables like mushrooms or bell peppers, sauté them first to cook off their water content.
- Use Full-Fat Cheese: Full-fat cream cheese and whole-milk mozzarella not only taste better but also melt more smoothly and help create a richer texture.
- Let It Rest: Don’t skip the resting period after baking! It’s essential for the casserole to firm up, ensuring you can serve clean, beautiful slices instead of a soupy mess.
Customizations and Variations
One of the best things about this recipe is how easy it is to customize. Here are a few ideas to get you started:
- Supreme Pizza Casserole: Add cooked mushrooms, sliced bell peppers, onions, and black olives to the sausage mixture.
- Meat Lover’s Dream: Mix in some cooked ground beef, crispy bacon, and diced ham along with the Italian sausage.
- Different Cheeses: For a more complex flavor, try adding some provolone, parmesan, or asiago cheese to the mozzarella topping.
- Spice It Up: Add a pinch of red pepper flakes to the sauce for a little extra heat.
