This creamy baked tortellini with ricotta and spinach is a cozy pasta dinner with a softer, creamier character than a traditional tomato casserole. Cheese tortellini are coated in garlicky marinara and ricotta, tucked under mozzarella, and baked until the edges bubble. Spinach adds color and balance, while a short bake turns the filling into a family-style dish that feels special without demanding much prep.
Why You’ll Love This Baked Tortellini
- Comforting and creamy: Ricotta melts into the sauce and gives the casserole a soft, spoonable texture.
- Weeknight practical: Refrigerated or frozen tortellini make the prep much quicker than homemade pasta.
- Vegetable-friendly: Spinach folds into the sauce without taking over the dish.
- Make-ahead capable: Assemble the casserole earlier in the day and bake when dinner is close.
- Easy to adapt: Add mushrooms, cooked sausage, roasted peppers, or herbs to suit the table.
Ingredients
This makes 6 servings in a 9-by-13-inch baking dish. Use refrigerated cheese tortellini if available; frozen tortellini also works with a few extra minutes of cooking.
- 20 ounces refrigerated cheese tortellini
- 2 tablespoons olive oil
- 3 garlic cloves, minced
- 1 jar marinara sauce, 24 ounces
- 1/2 cup low-sodium vegetable broth
- 1 cup whole-milk ricotta
- 1/2 teaspoon Italian seasoning
- 1/2 teaspoon kosher salt
- 1/4 teaspoon black pepper
- 5 ounces baby spinach
- 1 1/2 cups shredded mozzarella
- 1/4 cup grated Parmesan
- 2 tablespoons chopped fresh basil, optional
Whole-milk ricotta gives the smoothest sauce, but part-skim ricotta is fine. If the ricotta is very wet, drain it in a fine strainer for 10 minutes so the casserole stays creamy rather than watery.
How to Make It Step by Step
- Heat the oven. Set the oven to 375°F and grease a 9-by-13-inch baking dish. Put a large pot of salted water on to boil if you are using refrigerated tortellini.
- Cook the tortellini briefly. Boil the pasta for 2 minutes less than the package directions. It should be firm because it will finish cooking in the oven. Drain it well and set it aside. If using frozen tortellini, cook it according to the package and drain thoroughly.
- Build the sauce. Warm the olive oil in a large skillet over medium heat. Add the garlic and cook for 30 seconds. Pour in the marinara and broth, then stir in the ricotta, Italian seasoning, salt, and pepper. Simmer for 3 to 4 minutes, whisking until the ricotta is mostly blended.
- Wilt the spinach. Add the spinach a handful at a time and stir until it wilts, about 2 minutes. The sauce should be thick enough to coat a spoon. Taste and adjust the seasoning before adding the pasta.
- Combine. Fold the cooked tortellini into the sauce carefully so the pasta does not tear. Transfer the mixture to the baking dish and spread it into an even layer.
- Add the cheese. Sprinkle mozzarella over the top, followed by Parmesan. Cover the dish loosely with foil, keeping the foil from touching the cheese.
- Bake. Bake covered for 15 minutes, then uncover and bake for 10 to 15 minutes more, until the cheese is melted and the edges are bubbling. Broil for 1 minute if you want a more golden top.
- Rest and serve. Let the casserole rest for 5 minutes, then scatter over fresh basil. Spoon it into shallow bowls so the sauce and cheese stay together in every serving.
Tips and Variations
Keep the pasta from becoming soft
Undercook the tortellini slightly before baking. It continues to absorb sauce in the oven, and fully cooked pasta can become too soft after the casserole rests. Drain it well so extra water does not thin the ricotta sauce.
Add more vegetables
Sauté sliced mushrooms, diced zucchini, or chopped bell peppers with the garlic before adding the marinara. Roasted red peppers and artichoke hearts can be stirred in directly. If using frozen spinach, thaw it and squeeze out excess water first.
Make it meaty
Brown 1 pound of Italian sausage or ground beef before making the sauce. Drain excess fat, then continue with the garlic and marinara. Shredded rotisserie chicken is another easy addition and works especially well with a little extra Parmesan.
Plan a complete Italian-style meal
Serve a crisp green salad beside the casserole and offer warm bread for scooping up sauce. For another pasta bake, try the dump-and-bake chicken Alfredo tortellini. The creamy homemade Alfredo sauce can be used for a white-sauce variation, while summer tortellini pasta salad is a fresh option for warmer days. A beef manicotti dinner offers another hearty pasta centerpiece.
Storage and Reheating
Cool leftovers and refrigerate them in a covered container for up to 4 days. Reheat individual portions in the microwave in 60-second intervals, or cover the baking dish and warm it at 325°F for 20 minutes. Add a tablespoon of broth or marinara if the sauce has tightened.
To make ahead, assemble the casserole, cover it, and refrigerate for up to 24 hours. Let it sit at room temperature for 20 minutes before baking and add 10 minutes to the covered baking time. You can freeze the assembled casserole for up to 2 months, but the ricotta texture may be slightly grainier after thawing. Thaw overnight and bake until hot and bubbling.
This recipe contains dairy and wheat, and packaged pasta or sauce can include additional ingredients. Check labels and avoid cross-contact when serving someone with an allergy; the FDA food-allergy guide explains major allergens and label information.
If you are serving this for guests, assemble the dish in the afternoon and keep the topping cheese separate until just before baking. That keeps the mozzarella fresh and makes the finished top especially glossy. Put a bowl of red pepper flakes and grated Parmesan on the table so everyone can season their own serving without changing the whole casserole.

A final drizzle of olive oil or a few torn basil leaves gives the casserole a fresh finish. Let each serving stand for a minute in the bowl before eating; the sauce settles around the tortellini and the cheese becomes easier to scoop. This small rest also keeps the first spoonful from being too hot.

Frequently Asked Questions
What makes baked tortellini with ricotta and spinach creamy?
Whole-milk ricotta is stirred into the marinara before baking, so it melts into the sauce and coats the tortellini. Mozzarella and Parmesan add a stretchy, browned topping without needing a separate cream sauce.
Can I use frozen tortellini?
Yes. Cook it according to the package directions, drain it well, and fold it into the sauce. Frozen pasta may need a few extra minutes in the oven, so bake until the center is hot and the edges bubble.
Can I make this casserole without spinach?
Absolutely. Leave it out or replace it with sautéed mushrooms, roasted peppers, kale, or chopped broccoli. Cook firm vegetables before adding them so the sauce does not become watery.
How can I make the casserole less rich?
Use part-skim ricotta, reduce the mozzarella to 1 cup, and add extra spinach or vegetables. A bright green salad with lemon dressing also balances the creamy pasta.
Can I use tomato sauce instead of marinara?
Yes, but tomato sauce may need extra garlic, basil, oregano, and a pinch of salt. Taste the sauce before mixing in the tortellini so the finished casserole has enough seasoning.
