Ingredients You’ll Need

All the ingredients come together harmoniously to give you that classic pizza taste but in a casserole form that’s so satisfying. When shopping, grabbing good-quality pepperoni really elevates the final dish, and a rich pizza sauce makes a noticeable difference.

• Rotini pasta: Its spiral shape traps sauce and cheese perfectly, so every bite’s packed with flavor.
• Pizza sauce: Use your favorite brand or homemade for the best tomatoey base.
• Diced pepperoni: Bite-size pieces blend in well, making the casserole easier to eat.
• Whole pepperoni: These go on top for eye appeal and a chewy texture contrast.
• Mozzarella cheese (shredded): Melts beautifully — creamy and gooey in every forkful.
• Dried oregano: A sprinkle on top adds that classic Italian herbal aroma and taste.

Variations

I love making this Pepperoni Pizza Casserole Recipe my own by tweaking ingredients based on what I have in the fridge or what I’m craving. You should definitely feel free to personalize it — that’s half the fun!

• Meat lovers: I once added cooked Italian sausage along with the pepperoni, and my family went crazy for the extra hearty flavor.
• Vegetarian twist: Swap the pepperoni for mushrooms and bell peppers — still delicious and super satisfying.
• Cheese upgrade: Mixing in provolone or parmesan with the mozzarella adds a fun depth of flavor.
• Spicy kick: Adding red pepper flakes to the sauce gave it a little heat that I enjoyed on a chilly night.

How to Make Pepperoni Pizza Casserole Recipe

Step 1: Prep and Cook Pasta

Start by preheating your oven to 350°F and spraying your casserole dish with non-stick cooking spray – this little step saves you from any stubborn sticking later. Cook your rotini pasta following the package instructions until it’s just al dente; that’s key because you don’t want mushy pasta after baking. Drain well and return it to the pot while still warm — this is where the magic begins!

Step 2: Mix the Filling

To the cooked pasta, stir in the pizza sauce, diced pepperoni, and about 1½ cups of shredded mozzarella cheese. Mixing while the pasta’s warm lets the cheese start melting subtly, binding everything together beautifully. Give it a good stir so every piece of pasta gets coated in that saucy, cheesy goodness.

Step 3: Assemble the Casserole

Pour the pasta mixture into your prepared casserole dish, spreading it evenly. Now sprinkle the remaining mozzarella on top, followed by arranging the whole pepperoni slices evenly over the cheese. I like to add a light dusting of dried oregano here for that final burst of pizza flavor and aroma.

Step 4: Bake Until Melty

Bake the casserole for 7 to 10 minutes or until the top cheese is completely melted and bubbly. Keep an eye on it — you want gooey cheese, not browned or crusty spots. Once out of the oven, I like to let it cool 2-3 minutes before serving so it sets just a bit and is easier to portion.

How to Serve Pepperoni Pizza Casserole Recipe

Garnishes

I like to sprinkle some freshly chopped basil or a pinch of crushed red pepper flakes on top to brighten the flavors and add a little pop. A light drizzle of good olive oil right before serving also lifts the whole dish beautifully. Sometimes, grated parmesan on the side makes it feel extra special.

Side Dishes

Pair this casserole with a simple green salad tossed in a tangy vinaigrette or some garlic breadsticks to round out the meal. Roasted veggies like broccoli or a fresh cucumber salad balance the cheesy richness perfectly and keep things feeling light.

Creative Ways to Present

For family dinners, I sometimes serve it straight from the casserole dish with colorful serving spoons. But for a party or potluck, layering it in individual ramekins or mini casserole dishes makes a fun presentation that everyone loves. You can even top each serving with a fresh basil leaf for a pop of color.

Make Ahead and Storage

Storing Leftovers

I usually cover leftover casserole tightly with foil or plastic wrap and keep it in the fridge for up to 3 days. It reheats beautifully and tastes just as good because the flavors meld overnight. Just make sure to cool it before refrigerating to prevent sogginess.

Freezing

This casserole freezes really well — I portion it into airtight containers or wrap tightly in foil and plastic wrap. When I freeze, I label it with the date and enjoy it within 2 months for best flavor. Thaw overnight in the fridge before reheating.

Reheating

To reheat leftovers, I pop portions into the oven at 350°F for about 15 minutes or until warmed through, which keeps the cheese melty and the casserole moist. Microwaving works too, but I recommend adding a splash of water and covering loosely to avoid dryness.
