How to Make Comforting and Cheesy Vegetarian Pizza Casserole for the Whole Family Recipe
Step 1: Cook the pasta
Start with a large pot of salted boiling water, and cook your pasta according to the package directions until it is just al dente. This ensures the noodles remain tender but firm enough to hold up in the casserole. Drain and set aside while you prepare the rest of the ingredients.
Step 2: Sauté the vegetables
Heat the olive oil over medium heat in a large skillet, then add the chopped onion, green bell pepper, and sliced mushrooms with a pinch of salt. Sauté for about 5 to 7 minutes until the vegetables soften and develop a slight golden color, which brings out their natural sweetness and depth of flavor.
Step 3: Season the sauce
Pour the marinara sauce into the skillet with the sautéed vegetables. Sprinkle in dried oregano, dried basil, garlic powder, and black pepper to season. Let this delicious mixture simmer gently for 3 to 5 minutes so the flavors mingle beautifully, creating a perfectly balanced savory base.
Step 4: Combine pasta and sauce
Transfer the cooked pasta into a large mixing bowl or directly into your greased baking dish, then pour the sauce and vegetable mixture over it. Stir until every piece of pasta is coated generously, ensuring that each bite will be bursting with flavor and texture.
Step 5: Layer the casserole
Spread half of the pasta and sauce mixture into the bottom of your 9×13-inch baking dish that you’ve lightly greased. Sprinkle evenly with half of the mozzarella and Parmesan cheese. Layer the rest of the pasta mixture on top and finish by covering it with the remaining cheese. Scatter the sliced black olives on top to add that signature pizza flair.
Step 6: Bake the casserole
Place the dish in a preheated oven at 375°F (190°C) and bake uncovered for 20 to 25 minutes. Watch for the cheese to melt into a bubbly, golden crown that looks as inviting as it tastes, signaling that your casserole is nearly ready to be devoured.
Step 7: Cool and serve
Allow your casserole to rest for about 5 minutes outside the oven. This brief cooldown period helps it set and makes slicing easier. Garnish with fresh basil leaves or a sprinkle of red pepper flakes if you like a touch of heat to brighten up the warm, cheesy goodness.

Garnishes
Fresh basil or parsley adds a pop of color and fresh herbaceous notes that contrast beautifully with the rich cheese. For a little extra zing, consider crushed red pepper flakes or a drizzle of high-quality olive oil to finish the dish with depth and shine.
Side Dishes
This casserole pairs wonderfully with a crisp green salad dressed lightly with lemon vinaigrette or a side of roasted garlic bread. These simple accompaniments provide a refreshing crunch and bright acidity to balance out the hearty, cheesy main.
Creative Ways to Present
Serve individual portions scooped into mini ramekins for fun, personalized servings. You can also sprinkle chopped fresh tomatoes or banana peppers on top right before serving to add an extra layer of freshness and color that will impress your guests.
Make Ahead and Storage
Storing Leftovers
Any leftover Comforting and Cheesy Vegetarian Pizza Casserole for the Whole Family Recipe can be stored in an airtight container in the refrigerator for up to 3 to 4 days. The flavors tend to deepen after a day, making leftovers even more delicious.
Freezing
You can freeze this casserole before baking by covering it tightly with foil and plastic wrap. It will keep well for up to 2 months. Just thaw overnight in the fridge before baking as directed for a fresh-from-the-oven experience whenever you need a comforting meal ready to go.
Reheating
Reheat the casserole in a 350°F (175°C) oven until warmed through and bubbly, usually 15 to 20 minutes. For quicker reheating, the microwave works well but may soften the texture slightly—cover loosely to retain moisture without making it soggy.

Yes, you can substitute the mozzarella and Parmesan with vegan cheese alternatives and use a plant-based marinara sauce to keep it entirely vegan while still deliciously cheesy and comforting.
