Ingredients List

Here’s everything you need to pull together this cheesy, bubbly, pizza-inspired casserole. Most can be found in your pantry or fridge:

1 (20 oz) package cheese tortellini (fresh or refrigerated recommended)
1 jar (24 oz) marinara or pizza sauce (use your favorite brand)
1 to 1½ cups shredded mozzarella cheese, divided
½ cup shredded Parmesan cheese
1 teaspoon Italian seasoning
½ teaspoon garlic powder
20-30 slices pepperoni (mini or regular works great)
Optional toppings: Sliced black olives, chopped green peppers, red onion, mushrooms
Salt and pepper to taste
Cooking spray

Note: Feel free to swap in plant-based cheese or vegan pepperoni if you’re going meatless!

Step-by-Step Directions

Ready to get cooking? Here’s how to build your pepperoni pizza pasta casserole masterpiece:

Preheat oven to 375°F (190°C).
Boil the tortellini according to package directions, then drain.
Grease a 9×13 baking dish lightly with cooking spray.
In a large mixing bowl, combine cooked tortellini, marinara sauce, Italian seasoning, garlic powder, ¾ cup of the mozzarella, and all of the Parmesan. Mix until well-coated.
Spread the mixture into the baking dish, leveling it out with a spoon or spatula.
Top with remaining mozzarella and arrange pepperoni slices evenly across the top.
Optional: Add any extra toppings now (olives, mushrooms, onions).
Bake for 20–25 minutes, or until cheese is melted and bubbly. You’ll see golden edges when it’s ready.
Let it cool for 5 minutes before serving—trust me, it’s worth the wait!

Isn’t it amazing when your kitchen smells like your favorite pizzeria?

Common Mistakes to Avoid

Even simple recipes can go sideways sometimes. Here’s what to watch out for:

Overcooking the tortellini: It will turn mushy. Cook just until al dente before baking.
Forgetting to grease the baking dish: This can make cleanup a nightmare—don’t skip it!
Using too much sauce: Sounds strange, but too much can make everything soggy. Stick to about 24 oz.
Skipping the seasoning: A pinch of garlic powder and Italian herbs takes the flavor up a notch.
Not covering to store: Always use foil or an airtight lid to avoid drying out leftovers.

A little care goes a long way toward casserole perfection.

Best Side Dishes

While this is a hearty main dish, adding a complementary side really rounds out the meal. Here are a few favorites:

Garlic bread or cheesy breadsticks: Because you can never have too much cheese and carbs, right?
Caesar salad: Crisp romaine, creamy dressing, and crunchy croutons balance the rich pasta flavors.
Roasted vegetables: Think zucchini, cherry tomatoes, or broccoli tossed in olive oil and herbs.
Caprese salad: Fresh mozzarella, tomatoes, and basil—light and fresh for a touch of contrast.

Pairing pasta casserole with something fresh or crunchy makes the whole meal feel intentional (and extra delicious).

Expert Recipe Tips

Want to impress even the pickiest eaters or elevate your casserole game? These tips will help:

Swap in spicy pepperoni or sausage for a little heat if your crowd can handle it.
Add a layer of ricotta cheese in the middle for a lasagna-style richness.
Use chopped fresh basil as a garnish after baking for a fragrant finish.
Make it vegetarian: Just skip the pepperoni and go heavy on veggies like mushrooms, peppers, and spinach.
Try smoked mozzarella or provolone: Adds a flavor twist pizza lovers will appreciate.

Small tweaks, big flavor payoffs.

Storage and Reheating Instructions

This casserole is just as delicious the next day—maybe even better. Here’s how to store and bring it back to life:

Refrigerate: Store leftovers in an airtight container or tightly covered with foil for up to 4 days.
Freeze: Wrap the entire baked casserole in foil, then place in a freezer bag. Keeps up to 2 months.
Reheating in oven: Cover with foil and bake at 350°F for 15–20 minutes, until warmed through.
Microwave option: Heat individual portions on high for 2–3 minutes, stirring halfway through.

Pro tip: Add a spoonful of marinara and a sprinkle of fresh cheese when reheating to keep it moist and fresh-tasting.
