Essential Ingredients for Your Pizza Casserole
- 32 ounces low sodium marinara sauce: This forms the flavorful base of your casserole. Using a low-sodium variety helps keep the dish healthier without sacrificing taste. Feel free to use your favorite brand, or even combine marinara with a little pizza sauce for a more robust, authentic pizza flavor profile.
- 4 cups water: Essential for perfectly boiling your pasta to the ideal al dente texture.
- 1/2 teaspoon sea salt: Adding salt to the pasta water is crucial; it seasons the pasta from within as it cooks, enhancing the overall flavor of the dish.
- 6 ounces dry cellentani pasta: Cellentani pasta, with its unique corkscrew shape, is excellent for this dish because it expertly captures and holds the sauce and small pieces of toppings in every bite, making it both fun and incredibly filling. Other spiral or tube-shaped pastas like rotini or penne also work well.
- 2 ounces pork pepperoni: Diced pepperoni ensures a burst of savory, spicy pizza flavor in every forkful. A portion is also reserved and placed whole on top to achieve that classic, visually appealing supreme pizza look, adding a delightful crispy texture after baking.
- 1/4 cup black olives: Olives contribute a distinctive briny, savory flavor and a welcome portion of vegetables, adding depth and a Mediterranean touch to the casserole. Sliced green olives can also be used for a different taste.
- 1/2 red bell pepper: Diced red bell pepper complements the marinara sauce beautifully, adding a natural sweetness and a vibrant color that carries throughout the dish. Its subtle crunch also adds a lovely textural contrast. A green bell pepper can be used for a slightly more robust, less sweet flavor.
- 2 turkey Italian sausage links: Opting for turkey Italian sausage provides a lighter alternative to traditional pork sausage, while still infusing the casserole with an abundance of savory, herbaceous flavor. The added protein makes the meal more substantial and filling than pasta alone, and it contributes a delicious, well-seasoned taste.
- 1 cup low-fat mozzarella cheese: Mozzarella cheese is indispensable for creating that signature gooey, stretchy texture that is so reminiscent of an authentic pizza. Using a low-fat variety helps to keep the casserole lighter. An Italian cheese blend, provolone, or even a sprinkle of Parmesan can also be used for varied flavor and texture.
- 1/2 teaspoon Italian seasoning or Pizza seasoning: This aromatic seasoning blend is key to imparting that classic herb-infused pizza flavor. While Italian seasoning offers a general Mediterranean blend, dedicated pizza seasoning often includes ingredients like oregano, basil, thyme, and sometimes a hint of red pepper flakes for a bolder kick.
Step-by-Step Instructions for Making Your Perfect Pizza Casserole
1. Preheat your oven to 400°F (200°C). Prepare an 8×8-inch baking dish by coating it thoroughly with cooking spray; set it aside. In a large pot, bring the 4 cups of water and 1/2 teaspoon of sea salt to a rolling boil over high heat. Once boiling, add the dry cellentani pasta and cook for 8-10 minutes, or until it is al dente. It’s crucial not to overcook the pasta at this stage, as it will continue to cook in the oven. Once al dente, drain the pasta thoroughly.

2. Transfer the cooked and drained pasta into a large mixing bowl. Pour the entire 32 ounces of marinara sauce over the pasta. Stir gently but thoroughly to ensure every piece of pasta is evenly coated in the rich sauce.

3. In a skillet set over medium heat, brown the turkey Italian sausage (with casing removed). Use a spatula or wooden spoon to break the sausage into small crumbles as it cooks. Continue to cook for approximately 7-10 minutes, or until no pink remains and it is fully cooked through. Ensure it is nicely browned for maximum flavor.

4. Add the cooked and crumbled sausage, the quartered pepperoni pieces, and the diced red bell pepper to the mixing bowl with the pasta and sauce. Stir all the ingredients together until they are well combined and evenly distributed throughout the mixture.

5. Scrape the entire pizza casserole mixture into your prepared 8×8-inch baking dish, spreading it out into an even layer with your spatula.

6. Top the casserole with an even layer of the low-fat mozzarella cheese, ensuring good coverage over the entire surface.

7. Arrange the reserved whole pepperoni slices and scatter the sliced black olives on top of the mozzarella cheese. Finally, sprinkle the Italian seasoning generously over everything. Place the dish into the preheated oven and bake for 20-25 minutes. The baking time may vary slightly depending on your oven, so keep an eye on it.

8. Your pizza casserole is done when the sides are visibly bubbling, and the cheese on top is beautifully browned, melted, and gooey. Once removed from the oven, let the casserole cool and rest for about 10 minutes before serving. This crucial resting period allows the casserole to set, making it easier to scoop and preventing it from being too runny.

Customizing Your Pizza Casserole: Variations and Substitutions
- Swap the Pasta: Don’t feel limited to cellentani! You can easily use a different shape of pasta in this recipe, such as penne, ziti, rotini, or even elbow macaroni. For an added boost of fiber and protein, consider using whole-wheat pasta, rice-based pasta for a gluten-free option, or chickpea pasta like Banza. Each will bring a slightly different texture and nutritional profile to your casserole.
- Add Your Favorite Veggies: This casserole is a fantastic vehicle for adding more vegetables. Sliced mushrooms (sautéed briefly before adding for best flavor), fresh spinach (stirred into the hot sauce to wilt), diced onions (caramelized for sweetness), green bell peppers, zucchini, yellow squash, broccoli florets, or even artichoke hearts and sun-dried tomatoes make great additions. Feel free to blend cooked softer vegetables like zucchini or carrots directly into the marinara for a hidden veggie boost.
- Try a Different Protein: While turkey Italian sausage offers a leaner option, you can certainly swap it for traditional pork Italian sausage if you prefer a richer flavor. For other variations, consider using lean ground beef, ground turkey, shredded cooked chicken, crumbled crispy bacon, or diced ham for a meat-lovers version. For a delicious vegetarian option, omit the meat entirely and add extra mushrooms, plant-based crumbles, or a can of drained cannellini beans.
- Want to Lower the WW Points? To further reduce the Weight Watchers points, decrease the dry pasta measurement to 4 ounces. To ensure the meal remains equally filling, compensate by adding 1 to 2 cups of additional non-starchy vegetables of your choice (like extra bell peppers, mushrooms, or spinach) and use 1-2 additional turkey sausage links or lean ground turkey. This strategy adds volume and satiety without significantly increasing points.
- Cheese Variations: While mozzarella is classic, feel free to experiment with other cheeses. A blend of Italian cheeses (mozzarella, provolone, parmesan), a sharp provolone, or even a sprinkle of crumbled feta on top can add different dimensions of flavor.
- Spicy Kick: If you love a bit of heat, consider adding a pinch of red pepper flakes to the marinara sauce, using spicy pepperoni, or incorporating finely diced jalapeños into the mixture. A dash of your favorite hot sauce can also be stirred in for an extra fiery layer.
- Gluten-Free Option: Easily make this recipe gluten-free by simply using your preferred brand of certified gluten-free pasta. Ensure all other ingredients are naturally gluten-free.
Tips and Tricks for a Perfect Pizza Casserole Every Time
- Avoid Overcooking the Pasta: This is a critical step for perfect casserole texture. Because the pasta will bake for an additional 20-25 minutes in the oven, you want to leave it slightly undercooked (al dente) while boiling. This ensures that it finishes cooking in the sauce and doesn’t become mushy or overly soft, which would negatively affect the overall texture of the dish. If you are using a different variety of pasta, pay close attention to its package cooking times, as they can differ.
- Ensure the Meat is Fully Cooked: Always be sure to fully cook and brown the turkey Italian sausage before adding it to the casserole mixture. It can be difficult to tell if it’s properly cooked once it’s mixed with other ingredients and baked, and undercooked meat is a food safety concern. Break it into small, even crumbles to ensure it cooks evenly and quickly.
- Chop Veggies into Bite-Sized Pieces: While long slices of peppers or onions might look great on top of a traditional pizza, for a casserole, smaller, bite-sized pieces work much better. This ensures that the flavors are evenly distributed throughout the dish and that you get a balanced taste in every bite, making it easier and more pleasant to eat.
- Add Fresh Herbs for Brightness: Elevate the flavor and presentation of your casserole by adding fresh herbs. A sprinkle of fresh sliced basil or chopped parsley as a garnish just before serving can give this casserole a wonderfully fresh, aromatic taste and a pop of color.
- Don’t Overcrowd the Dish: Using the recommended 8×8-inch baking dish ensures that the casserole bakes evenly and the cheese gets nicely browned. If you double the recipe or add a lot of extra ingredients, consider using a larger baking dish to prevent overcrowding, which can lead to uneven cooking.
- Rest Time is Crucial: While it might be tempting to dig in immediately, allowing the casserole to cool and rest for 10 minutes after it comes out of the oven is important. This allows the sauce to thicken slightly and the cheese to set, making it much easier to scoop out neat, cohesive servings without it falling apart.
- Storage and Reheating: Store any leftover pizza casserole in an airtight container in the refrigerator for up to 3-4 days. For reheating, individual servings can be quickly warmed in the microwave, or for a crispier top, reheat in a preheated oven at 350°F (175°C) until heated through.
- Freezing Instructions: This casserole freezes wonderfully. You can freeze it either baked and cooled, or assembled but unbaked. Wrap it tightly with plastic wrap and then aluminum foil. If frozen unbaked, thaw it in the refrigerator overnight before baking as directed. If frozen baked, thaw and then reheat.
- Serving Suggestions: Pair this hearty pizza casserole with a light, crisp green salad tossed with a vinaigrette dressing to balance the richness. Garlic bread or a simple focaccia can also be a delightful accompaniment.
