How to Make Pizza Casserole Recipe
Step 1: Cook the Pasta
Start by cooking your penne pasta according to the package instructions until it’s perfectly al dente. This texture is key because the pasta will absorb some of the sauce as it bakes, so you don’t want it too soft. Once cooked, drain thoroughly and set aside to cool slightly.
Step 2: Brown the Meats
In a large skillet over medium heat, brown the lean ground beef and pork sausage together, stirring occasionally to break it up. Cook until fully browned with no pink remaining, then drain off any excess fat. This step intensifies the meaty flavors that form the base of your pizza casserole.
Step 3: Combine the Flavorful Ingredients
Transfer your cooked meats to a large mixing bowl. Add the sliced pepperoni, chopped green bell pepper, onion, freshly grated Parmesan, oregano, minced garlic, mushrooms if you’re using them, and drained black olives. Each ingredient adds its own delicious note that builds the casserole’s depth and interest.
Step 4: Mix in Pasta and Sauce
Next, stir in the cooked pasta and pour the entire 24 ounces of marinara or pizza sauce over everything. Toss gently but thoroughly so that every bite is infused with that tangy, herb-forward tomato goodness. This mixture is the perfect harmony of classic pizza ingredients with comforting pasta.
Step 5: Prepare and Bake
Preheat your oven to 350°F (180°C) and grease a 9×13-inch baking dish. Pour the casserole mixture into the dish and spread it out evenly to ensure an even bake. Then, sprinkle 1 to 2 cups of shredded mozzarella cheese generously over the top—a cheesy topping is where pizza magic happens!
Step 6: Bake to Perfection
Bake in the preheated oven for 25 to 35 minutes until the cheese is melted, bubbly, and beautifully golden on top. Let the casserole rest for a few minutes before serving; this allows it to set slightly, making it easier to slice and even more enjoyable to eat.
How to Serve Pizza Casserole Recipe
Garnishes
A sprinkle of fresh basil or chopped parsley adds a lovely pop of green and bright fresh flavor that contrasts the rich cheese and sauce. A light dusting of extra Parmesan can also add a nice touch of sharpness just before serving.
Side Dishes
Because the casserole is rich and filling, pairing it with a crisp green salad or steamed veggies like broccoli or asparagus balances out the meal wonderfully. Garlic bread or a warm focaccia on the side is perfect if you want to keep doubling down on those Italian vibes.
Creative Ways to Present
For a fun twist, assemble the casserole in individual ramekins or mini skillets for personal servings that look impressive and keep everyone’s portions just right. You could also layer this casserole in a clear glass dish for a pretty, layered presentation that shows off all the colorful ingredients.
Make Ahead and Storage
Storing Leftovers
Once your meal is finished, allow the casserole to cool completely before storing. Cover tightly with plastic wrap or transfer to an airtight container and refrigerate for up to 3 days. The flavors meld beautifully overnight, making leftovers even tastier.
Freezing
This Pizza Casserole Recipe freezes wonderfully. Prepare and bake as usual, then cool completely and freeze in a freezer-safe container for up to 3 months. When ready to enjoy, thaw overnight in the refrigerator before reheating to maintain texture and flavor.
Reheating
Reheat in the oven at 350°F (175°C) for about 20 minutes or until warmed through and bubbly again. If you’re in a hurry, microwave individual portions covered with a microwave-safe lid or wrap, heating in 1-minute intervals until hot, though the oven method gives the best texture.
FAQs
Can I make this Pizza Casserole Recipe vegetarian?
Absolutely! Simply omit the ground beef, sausage, and pepperoni. You can add extra veggies like zucchini, eggplant, or more mushrooms to keep it hearty, and use a vegetarian pizza sauce to keep all those flavors vibrant.
What type of pasta works best?
Penne is ideal due to its tube shape which holds sauce well, but you can also use rotini or rigatoni. Just make sure whatever pasta you choose cooks to al dente so it doesn’t get mushy after baking.
Can I use homemade pizza sauce instead of store-bought?
Yes! Homemade pizza sauce adds a personal touch and can be adjusted to your preferred flavor profile—whether you like it spicy, sweet, or herby. Just use about 24 ounces or so to keep the right sauciness.
Is this dish suitable for meal prepping?
Definitely. This Pizza Casserole Recipe is great for preparing in advance and even freezing, making it an excellent choice for busy weeknights or batch cooking for the week ahead.
How can I make this recipe spicier?
Try adding crushed red pepper flakes when browning the meat or mix some spicy Italian sausage instead of sweet sausage. A few dashes of hot sauce in the marinara can also kick up the heat without overwhelming the other flavors.
