Ingredients You’ll Need
Don’t be fooled by the simplicity of this dish—the ingredients are straightforward but each plays a vital role in building the rich layers of flavor, texture, and color that define this recipe.
- 20 ounces refrigerated cheese tortellini: The cheesy pasta pillows form the hearty base of the casserole, offering a luscious texture.
- 2 cups marinara or pizza sauce: This sauce brings that classic tangy, herby tomato flavor that ties everything together.
- 1.5 cups shredded mozzarella cheese: Melts into a gooey, stretchy topping that’s synonymous with pizza goodness.
- 0.5 cup mini pepperoni slices: Adds that savory, slightly spicy punch that pep’s up your palate.
- 0.25 cup grated Parmesan cheese: Gives a sharp, nutty brightness that balances the richness.
- 1 teaspoon Italian seasoning: A blend of herbs that lifts the tomato sauce and warms the whole dish.
- 0.5 teaspoon garlic powder: Boosts depth with its subtle aromatic kick.
- 0.25 teaspoon crushed red pepper flakes (optional): For a gentle heat that awakens the taste buds.
- 1 tablespoon olive oil: Adds moisture and richness, helping the sauce cling to the tortellini.
- Fresh basil or parsley (optional): A fresh garnish that brings color and a pop of herbal brightness to finish.
How to Make Cheese Tortellini Pepperoni Pizza Casserole Recipe
Step 1: Prepare and Cook the Tortellini
Start by preheating your oven to 375 degrees Fahrenheit, then grease a 9×13-inch baking dish to make sure your gooey creation doesn’t stick. Cook the refrigerated cheese tortellini according to package directions, until just al dente—meaning they still have a slight bite to hold their shape without becoming mushy. Once cooked, drain them well to avoid excess moisture in your casserole.
Step 2: Combine Sauce and Seasonings
In a big bowl, toss the cooked tortellini with the marinara or pizza sauce, olive oil, Italian seasoning, garlic powder, and, if you like a bit of heat, the crushed red pepper flakes. This step ensures every cheesy pasta pillow is nicely coated and flavorful, setting the stage for that delicious pizza-inspired taste.
Step 3: Layer the Casserole
Place half of the tortellini mixture into your greased baking dish. Then sprinkle with half of the shredded mozzarella, mini pepperoni slices, and Parmesan cheese. Repeat this layering once more, because twice the cheese and pepperoni means twice the delight.
Step 4: Bake to Perfection
Bake your casserole uncovered for 25 to 30 minutes, until the cheese is melted, bubbling, and lightly golden on top. This step melds all those flavors and textures into one irresistible dish. When done, remove from the oven and let it rest for about 5 minutes—this little pause helps everything set nicely before serving.
How to Serve Cheese Tortellini Pepperoni Pizza Casserole Recipe

Garnishes
Adding fresh herbs like chopped basil or parsley just before serving gives a lovely color contrast and adds a bright, fresh flavor that complements the richness of the casserole perfectly. Sprinkle some extra Parmesan if you’re feeling indulgent!
Side Dishes
This casserole is a satisfying meal on its own, but pairing it with a crisp green salad or a side of garlic bread can elevate your dinner to restaurant-quality. The fresh crunch and vibrant veggies balance the cheesy comfort wonderfully.
Creative Ways to Present
For a fun twist, serve the casserole in individual ramekins for personalized portions. You can also add a drizzle of balsamic glaze or a pinch of red pepper flakes on top for a refined touch, making it perfect for casual dinners or special gatherings.
Make Ahead and Storage
Storing Leftovers
Your Cheese Tortellini Pepperoni Pizza Casserole Recipe leftovers are just as delicious chilled and stored in an airtight container in the refrigerator for up to 3 days. It’s a perfect make-ahead meal that heats back up beautifully.
Freezing
If you want to save some for later, this casserole freezes well. Wrap it tightly with plastic wrap and aluminum foil or use a freezer-safe container, then freeze for up to 2 months. Just remember to thaw it overnight in the refrigerator before reheating.
Reheating
Reheat leftovers in the oven at 350 degrees Fahrenheit for about 15 to 20 minutes until warmed through and bubbly again. Alternatively, a microwave works if you’re short on time, but the oven will keep that crispy top intact and cheese perfectly melty.
FAQs
Can I use frozen tortellini instead of refrigerated?
Yes, you can definitely use frozen cheese tortellini; just adjust the cooking time as per the package instructions so they cook evenly before assembling the casserole.
Is there a vegetarian option for this casserole?
Absolutely! Simply omit the pepperoni or substitute with plant-based pepperoni or veggies like mushrooms and bell peppers to keep it vegetarian-friendly without sacrificing flavor.
Can I make this casserole spicy?
Yes, the crushed red pepper flakes add a gentle heat, but you can increase the amount or add sliced jalapeños or spicy sausage for an extra kick.
How can I make the top extra crispy?
For a crispier cheese topping, broil the casserole for the last 2 minutes of baking, but watch closely to prevent burning.
Can I prepare this recipe ahead of time and bake later?
Definitely! Assemble the casserole in the baking dish, cover tightly, and refrigerate up to 24 hours before baking. Just add a few extra minutes to the baking time if it’s coming straight from the fridge.
