Pizza Tortellini combines cheese-filled pasta, pepperoni, and all those familiar pizza-shop toppings in one bubbly, cheesy casserole. The tortellini goes straight into the baking dish with pizza sauce, vegetables, and mozzarella, so there’s no separate pot of pasta to boil. It’s pizza night with a fork, and a generous layer of melted cheese!

Why You’ll Love This Recipe
This pizza tortellini bake keeps the prep simple: chop a few toppings, stir everything together in the baking dish, and let the oven do the cooking. No dough to stretch, no meat to brown, and no homemade sauce required.
The pepperoni does double duty here. Quartered pieces get stirred through the pasta, while whole slices go on top with mozzarella and black olives for that familiar pizza look. Green peppers, onions, and mushrooms give it a supreme-pizza feel, and a sprinkle of Parmesan and Italian seasoning finishes the top.
If you enjoy our penne pizza casserole, this is another way to bring pizza flavors to pasta night. The cheese-filled tortellini makes this version extra hearty without adding another cooking step.

Ingredients You’ll Need
You’ll find the complete measurements in the recipe card below. We’ve included our favorite pizza toppings but of course you can substitute any of the toppings (pepperoni, bells pepper, onion, mushrooms, and black olives) with what your family likes on their pizza.
- Tortellini – Fresh refrigerated or frozen tortellini is called for here. Cheese-filled tortellini pairs well with the pepperoni and pizza sauce; dried, shelf-stable tortellini isn’t a direct swap for this method.
- Mozzarella cheese – Some gets mixed into the casserole, and the rest goes on top. Shredded low-moisture mozzarella is a practical choice, and pre-shredded mozzarella is fine.
- Pizza sauce – Choose a sauce you enjoy, since it flavors the entire dish. Use the full amount called for so the pasta has plenty of sauce around it.
- Pepperoni – Regular sliced pepperoni works for both the quartered pieces inside and the whole slices on top. Turkey pepperoni is another option.
- Green bell peppers – Dice them into small, even pieces so they distribute throughout the pasta. Red bell pepper can be used for a sweeter flavor.
- Onion – A finely diced yellow onion adds savory flavor without leaving large chunks in the casserole.
- Mushrooms – Thinly sliced mushrooms mix easily with the tortellini. White button or baby bella mushrooms both suit these flavors.
- Black olives – Pitted, sliced black olives make an easy topping. Drain them well before adding them.
- Parmesan cheese – Grated Parmesan mixes with the herbs for a savory finish over the mozzarella.
- Italian seasoning – This dried herb blend adds another layer of pizza flavor to the topping.
How to Make Pizza Tortellini

Step 1 – Prepare the oven and baking dish. Preheat the oven to 400°F. Lightly grease a 9×13-inch baking dish.
Step 2 – Cut the pepperoni. Cut half of the pepperoni into quarters. Set the remaining whole slices aside for the topping.
Step 3 – Add the tortellini. Place the tortellini directly in the prepared baking dish.
Step 4 – Mix the casserole. Add 2 cups of mozzarella, the pizza sauce, quartered pepperoni, green peppers, onion, and mushrooms. Stir gently until the tortellini is coated in sauce and the vegetables and pepperoni are distributed throughout. Spread into an even layer, keeping the pasta nestled in the sauce rather than leaving dry pieces sticking up.
Step 5 – Mix the Parmesan topping. In a small bowl, stir together the Parmesan cheese and Italian seasoning.

Step 6 – Add the pizza toppings. Sprinkle the remaining 1 cup of mozzarella over the casserole. Arrange the whole pepperoni slices and black olives evenly over the cheese, just like topping a pizza.
Step 7 – Finish with the Parmesan mixture. Sprinkle the Parmesan and Italian seasoning over the top.
Step 8 – Cover and bake. Cover the dish with foil and bake for 30 minutes. Remove the foil and continue baking for an additional 15 minutes, or until the cheese is fully melted. Before serving, check a tortellini from the center of the dish: the pasta should be tender and its filling hot, with sauce bubbling around the casserole. If the pasta is still firm, cover again and continue baking until tender.
Step 9 – Serve hot. Scoop onto plates and serve with a side of garlic bread for the extra sauce.

Expert Tips & Tricks
- Seal the foil around the rim. The covered portion of baking helps hold moisture in while the pasta cooks.
- Keep the vegetables small. Finely dice the peppers and onion and thinly slice the mushrooms so they soften more evenly without a separate sautéing step.
- Be selective with extra toppings. Drain olives and other jarred additions well. A pile of extra wet vegetables can change the sauce consistency and how the casserole cooks.
Easy Variations
For a simpler pepperoni pizza version, leave out any vegetables your family doesn’t enjoy. Keep the tortellini, sauce, and cheese amounts the same.
For a little heat, use spicy pepperoni or add a pinch of crushed red pepper. You can also swap some of the pepperoni for cooked, drained Italian sausage, but that adds a separate browning step. Don’t stir raw sausage into the casserole.
If you’re making a meatless version, omit the pepperoni and use cheese tortellini. Check the tortellini and cheese labels if you need the finished dish to be strictly vegetarian.
What to Serve with Pizza Tortellini
I would keep the sides simple: Texas toast garlic bread for scooping up sauce and a crisp green salad with Italian dressing. Steamed broccoli or a plate of crunchy raw vegetables also works when you want something fresh alongside the cheesy pasta.

How to Store and Reheat
Refrigerate: Divide leftovers into shallow airtight containers and refrigerate within 2 hours, or within 1 hour if the temperature is above 90°F. Keep refrigerated at 40°F or below and use within 3 to 4 days.
Freeze: Pack cooled portions into freezer-safe containers and freeze for up to 2 months for best texture. Thaw in the refrigerator before reheating. The tortellini may be a little softer after freezing and reheating.
Reheat: For a single serving, use a microwave-safe dish with a vented cover and heat in short intervals, stirring gently between them. For larger portions, cover an oven-safe dish with foil and reheat at 350°F. Add a small splash of water or a spoonful of pizza sauce if the pasta looks dry. With either method, check that the center reaches 165°F, following USDA guidance for reheating leftovers.
Frequently Asked Questions
No separate boiling step is included in this recipe. The fresh or frozen tortellini goes into the baking dish with the sauce and cooks during the covered and uncovered baking stages. Check the pasta itself for tenderness before serving.
Dried tortellini needs a different amount of liquid and cooking time, so it isn’t a direct substitute in this no-boil casserole. Stick with the fresh or frozen type specified rather than using the same baking instructions for dried pasta.
Marinara can provide a similar tomato-and-herb flavor, but brands vary in thickness. A thinner sauce may leave the casserole looser, while a very thick sauce can make it harder for the pasta to cook evenly. Pizza sauce is the starting point for this recipe; a marinara substitution may affect the finished texture.
Yes! Dice the peppers and onion, slice the mushrooms, quarter half the pepperoni, and measure the cheeses ahead. Refrigerate the perishable ingredients separately, then assemble before baking. That gets the chopping out of the way without changing the pasta’s starting texture by letting it sit in sauce overnight.
Use two 9×13-inch baking dishes rather than piling a double batch into one pan. An extra-deep layer can cook unevenly. If both dishes are in the oven together, check each casserole for tender pasta and a hot center rather than relying only on the timer.
