What You’ll Need for Pesto Tortellini
The beauty of pesto tortellini is how simple the ingredients are.
Cheese tortellini is the foundation of the dish. These small pasta pockets are already filled with creamy cheese, which gives the casserole a rich texture without needing a lot of extra ingredients.
Basil pesto is what gives the dish its signature flavor. The combination of basil, garlic, olive oil, and parmesan adds brightness and depth that pairs perfectly with the creamy tortellini.
A little cream is added to the pesto to loosen the sauce and help it coat the pasta evenly. This keeps the casserole creamy when it’s reheated later.
Mozzarella cheese melts over the top and creates that golden, bubbly finish that makes baked pasta so comforting.
Parmesan cheese adds a little salty richness that rounds everything out.
Simple ingredients that come together to make a pasta dish that feels much more impressive than the effort it takes.

Ingredients for Pesto Tortellini

The tortellini provides the pasta and filling, while the pesto and cheeses create a creamy sauce that holds everything together.
Ingredients For the Pesto Tortellini:

1 cup basil pesto
½ cup heavy cream
1½ cups shredded mozzarella cheese
½ cup grated parmesan cheese
½ teaspoon garlic powder
½ teaspoon black pepper

½ cup halved cherry tomatoes
¼ teaspoon red pepper flakes

How to Make Pesto Tortellini
Start by bringing a large pot of salted water to a boil. Add the cheese tortellini and cook according to the package directions until just tender. Tortellini cooks quickly, so keep an eye on it and avoid overcooking.
Drain the pasta and set it aside.
In a large mixing bowl, combine the basil pesto, heavy cream, garlic powder, black pepper, and half of the parmesan cheese. Stir everything together until the sauce is smooth and well blended.
Add the cooked tortellini to the bowl and gently toss until all of the pasta is coated in the creamy pesto sauce.
At this point the tortellini should look glossy and evenly coated.
Transfer the pasta mixture into a foil casserole dish and spread it into an even layer.
Sprinkle the mozzarella cheese evenly over the top of the casserole, followed by the remaining parmesan cheese.
Allow the dish to cool completely before covering it tightly with aluminum foil.
Label the casserole and place it in the freezer for later.
When you’re ready to eat, bake the casserole covered at 375°F for about 40–50 minutes until the center is hot and the cheese is melted and bubbly.
Remove the foil during the last 10 minutes of baking if you want a lightly golden top.
Substitutions and Variations
Once you’ve made pesto tortellini once, it’s easy to customize depending on what you have available.
Chicken Pesto Tortellini
Add cooked shredded chicken to the pasta mixture before assembling the casserole. This makes the dish more filling and adds extra protein.
Sun-Dried Tomato Pesto Tortellini
Stir in chopped sun-dried tomatoes for a slightly tangy flavor that pairs really well with pesto.
Vegetable Pesto Tortellini
Add sautéed mushrooms, spinach, zucchini, or roasted vegetables to make the dish more vegetable-forward.
Spicy Pesto Tortellini
Add a pinch of red pepper flakes or chili oil for a little heat.
Extra Cheesy Pesto Tortellini

This recipe is flexible and forgiving, which makes it easy to adjust based on what you have in your kitchen.
What to Serve With Pesto Tortellini
Pesto tortellini is rich and satisfying, so pairing it with lighter sides works really well.
A crisp green salad with a simple vinaigrette helps balance the richness of the pasta. The fresh vegetables add brightness that complements the pesto.
Garlic bread or toasted baguette slices are another great option. They’re perfect for scooping up any extra pesto sauce on the plate.
Roasted vegetables like broccoli, asparagus, or green beans also pair nicely with the dish.
If you’re serving it for a larger dinner, pesto tortellini fits perfectly into an Italian-style meal with bruschetta, antipasto, or caprese salad.
Comforting pasta with fresh flavor.
Leftovers and Storage
This pesto tortellini casserole is designed to be frozen, so storing it properly is part of the plan.
Once the dish has cooled completely, cover the foil casserole tightly with aluminum foil. For extra protection against freezer burn, you can wrap the dish in plastic wrap before covering it with foil.
The casserole will keep well in the freezer for up to three months.
When you’re ready to cook it, remove any plastic wrap and bake the casserole covered at 375°F for about 40–50 minutes, or until the center is hot and the cheese has melted.
If you’d like the top slightly browned, remove the foil during the final 10 minutes of baking.
If you have leftovers after baking, store them in an airtight container in the refrigerator for up to four days.
