Can I use store-bought pizza sauce?

Absolutely. Choose a sugar-free or low carb variety for best results. If you have a favorite marinara or tomato sauce on hand, that works too—just be aware of the carb content if you’re strictly tracking.

Do I need to use a specific blend of cheeses?

Mozzarella is classic for pizza flavor and melt, but feel free to blend in provolone, cheddar, or even gouda for different flavor notes. Just make sure at least half is mozzarella for that signature stretch.

Are there make-ahead options?

You can prepare and bake the base layer in advance, then add sauce, toppings, and the final cheese layer just before serving. Or assemble fully, refrigerate overnight, and reheat and broil when ready to eat.

What toppings work best for keeping the casserole low carb?

Stick with meats like pepperoni, sausage, and bacon, and low carb veggies such as peppers, mushrooms, olives, spinach, or zucchini. Avoid high-sugar veggies like corn or pineapple for truly low carb results.

How to Make Low Carb Pizza Casserole

Step 1: Prep Your Oven and Dish

Preheat the oven to 350°F. Lightly grease a 9×13-inch baking dish with a bit of oil or nonstick spray to prevent sticking and make serving a breeze.

Step 2: Mix the Creamy Base

In a large mixing bowl, beat together cream cheese and eggs until the mixture is absolutely smooth. This step is key—lumps don’t bake out, so take a minute to get the base extra creamy.

Step 3: Stir in Flavor

Add grated Parmesan, heavy whipping cream, oregano, and minced garlic to the bowl. Stir thoroughly so the flavors are evenly distributed throughout the base.

Step 4: Construct Your Cheesy Foundation

Evenly spread 1 cup of shredded Parmesan and 1 cup of shredded mozzarella cheese across the bottom of your prepared baking dish. This melts into an incredibly cheesy, almost-crust-like layer that feels so decadent.

Step 5: Pour and Bake

Pour your egg and cheese mixture gently over the cheese layer and use a spatula to smooth it out. Bake uncovered for about 30 minutes, until the edges are slightly golden and the center is set.

Step 6: Sauce and Toppings!

Remove the dish from the oven. Spread the low carb pizza sauce evenly over the baked base. Layer on your favorite toppings—this is where you make it your own!

Step 7: Final Cheese Layer and Broil

Sprinkle the casserole with the remaining mozzarella. Add extra toppings if you wish. Pop it under the broiler for a few minutes, watching closely, until the top is bubbly and golden with a bit of irresistible browning.

Step 8: Let Rest

Allow the casserole to cool for about 5-10 minutes so everything sets up nicely. Then slice, serve, and bask in the glow of pizza night made simple.

Pro Tips for Making the Recipe

Smooth That Base: Take your time beating the eggs and cream cheese—no one wants little lumps hiding in the final bake.
Pre-cook Toppings: For best results, cook any meat or veggies that release lots of moisture before adding them as toppings. This keeps the casserole from getting soggy.
Watch the Broil: Broilers go from zero to burnt quickly! Stay close while browning the top for a perfect golden finish.
Customize Sauce Amount: Love saucy pizza? Add a bit more sauce. Prefer it with just a whisper of tomato? Use less. You’re in the driver’s seat!
