How to Make Mama’s Pizza Casserole Recipe
Step 1: Prepare Your Oven and Baking Dish
Start by preheating your oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish to prevent sticking and help the cheese brown beautifully. This simple prep ensures a smooth baking process and an easy cleanup later.
Step 2: Cook the Meat and Aromatics
In a large skillet over medium heat, cook the ground beef with diced onion and minced garlic. Stir occasionally until the beef is browned and the onion softens, releasing its sweetness. Drain any excess fat so your casserole keeps a balanced richness without being greasy.
Step 3: Mix in Sauce and Toppings
Stir the pizza sauce, drained black olives, half of the pepperoni slices, and Italian seasoning into the meat mixture. Season with salt and pepper to your liking. This combination builds the hearty, tangy base that carries all the flavors in the casserole.
Step 4: Combine with Pasta
Add the cooked rotini or penne pasta directly into the skillet and stir until the pasta is evenly coated with the meat and sauce mixture. This step ensures that every bite delivers a perfect blend of textures and flavors.
Step 5: Assemble and Bake
Transfer the pasta and meat mixture into your prepared baking dish. Top evenly with the shredded mozzarella and cheddar cheese, then arrange the remaining pepperoni slices over the cheese layer. Bake for 20 to 25 minutes or until the cheese bubbles, melts, and turns golden in spots. Let it cool for 5 minutes to set before serving.
How to Serve Mama’s Pizza Casserole Recipe

Garnishes
Fresh garnishes add a welcoming touch and extra flavor to your casserole. Sprinkle chopped fresh basil or parsley on top for a pop of color and herbal brightness. A light drizzle of chili oil or a pinch of red pepper flakes can offer a delightful kick if you like a bit of heat.
Side Dishes
This casserole pairs wonderfully with crisp, refreshing sides. Consider a simple green salad tossed with lemon vinaigrette to cut through the richness. Garlic bread or a classic Caesar salad also complement the pizza-inspired flavors, making the meal feel complete and satisfying.
Creative Ways to Present
For a crowd-pleaser, serve portions in individual ramekins or mini cast-iron skillets to keep everyone’s serving hot and personalized. You can also layer the casserole in a clear glass dish for a fun, visual showcase of the colorful ingredients and melted cheese layers.
Make Ahead and Storage
Storing Leftovers
Leftovers from Mama’s Pizza Casserole Recipe store beautifully in an airtight container in the fridge for up to 3 days. This makes it perfect for meal prepping or enjoying quick lunches that still feel like a special treat.
Freezing
If you want to save the casserole for later, freeze it unbaked in a covered dish or wrapped tightly with foil and plastic wrap. It stays fresh for up to 2 months. When ready, thaw overnight in the refrigerator before baking as directed.
Reheating
Reheat leftovers in the oven at 350°F (175°C) covered with foil to keep the moisture intact, for about 15 to 20 minutes, or until heated through. Alternatively, a microwave works well for quicker reheats, but covering it helps maintain gooey cheese without drying out.
FAQs
Can I use different types of pasta for this casserole?
Absolutely! While rotini or penne is recommended because they hold the sauce well, you can experiment with rigatoni, shells, or even fusilli. Just be sure to cook the pasta al dente so it doesn’t get mushy after baking.
Is this recipe suitable for a gluten-free diet?
Yes, by substituting regular pasta with a gluten-free variety, you can enjoy Mama’s Pizza Casserole Recipe without worry. Just make sure your pizza sauce and other ingredients are free from gluten additives too.
Can I add more vegetables to the casserole?
Definitely! Feel free to customize this dish with bell peppers, mushrooms, spinach, or even zucchini. Adding veggies boosts the nutritional value and introduces fresh flavors that complement the rich base nicely.
What’s the best way to reheat leftover pizza casserole to keep it moist?
Reheating in the oven with a piece of foil covering the dish is best to keep the casserole moist and prevent the cheese from drying out. A light sprinkle of water before covering can also help preserve moisture during reheating.
Can I prepare this casserole ahead of time and bake it later?
Yes, you can assemble the casserole a day in advance, cover it tightly, and store it in the fridge. When you’re ready, just pop it into the preheated oven and bake according to instructions. It’s a perfect dish for easing dinner prep on busy days.
