Ingredients You’ll Need
Getting started with the Baked Tortellini Casserole Recipe means gathering a handful of straightforward ingredients, each one playing a vital role in building luscious taste and delightful texture.
- 20 ounces cheese tortellini: The star of the dish, bringing a burst of cheesy pockets that soak up all the rich sauce.
- 3 tablespoons olive oil: Provides a smooth base to sauté onion and garlic, adding depth to the flavor.
- 1 medium onion, diced: Adds sweetness and a soft bite that balances the hearty meat.
- 2 cloves garlic, minced: Infuses the dish with that irresistible aromatic punch.
- 1 pound ground beef or Italian sausage: Brings savory richness and a satisfying meaty texture.
- 1 teaspoon dried oregano: Offers subtle herbal warmth without overpowering the dish.
- 1 teaspoon dried basil: Adds a fresh, slightly sweet flavor that complements the tomato sauce.
- 1/2 teaspoon red pepper flakes (optional): A gentle kick to awaken your taste buds if you like a little heat.
- 24 ounces marinara sauce: The luscious, tangy base sauce that ties everything together.
- 1 cup heavy cream: Creates that creamy, dreamy consistency that makes the casserole so indulgent.
- 1 1/2 cups mozzarella cheese, shredded: Melts beautifully on top, giving you that golden cheesy crust.
- 1/2 cup parmesan cheese, grated: Adds a sharp, nutty punch as a perfect finishing touch.

- Fresh basil or parsley for garnish (optional): A fresh burst of color and herbaceous brightness before serving.
How to Make Baked Tortellini Casserole Recipe
Step 1: Prepare Your Oven and Tortellini
First things first, preheat your oven to 375°F (190°C). While it’s warming up, cook your cheese tortellini according to the package instructions. This usually takes just a few minutes – make sure to drain them well and set aside because they’ll soak up all the delicious sauce later!
Step 2: Build the Flavor Base
In a large skillet, heat the olive oil over medium heat. Toss in the diced onion and sauté until soft and translucent, about 5 minutes. This step unlocks natural sweetness and gives a wonderful foundation for the sauce. Then, add the minced garlic and cook for just another minute to ensure it’s fragrant without burning.
Step 3: Brown the Meat
Now, add the ground beef or Italian sausage to the skillet. Break it apart with your spatula and cook until it’s fully browned and cooked through. This meaty layer is essential to infuse hearty flavor and texture into your casserole.
Step 4: Season the Mixture
Sprinkle in the dried oregano, dried basil, and (if you like a little heat) red pepper flakes. Season generously with salt and pepper. Stir everything well to combine, letting those herbs bloom into the meat for around a minute to meld the flavors.
Step 5: Simmer the Sauce
Pour in the marinara sauce and heavy cream, stirring everything together. Let the mixture simmer gently for about 5 minutes, so the cream softens the acidity of the tomatoes and creates a rich, velvety sauce that coats every bite of tortellini beautifully.
Step 6: Assemble and Bake
Grab a large baking dish and combine your cooked tortellini with the sauce mixture, tossing to coat every piece evenly. Sprinkle the shredded mozzarella and grated parmesan cheese on top for that irresistible golden crust. Pop it in the oven for 20 to 25 minutes until the cheese bubbles and turns beautifully golden.
Step 7: Let It Rest and Garnish
Once baked, pull your casserole out of the oven and let it cool for a few minutes – this helps everything set so it’ll hold together when you serve. Finish with fresh basil or parsley for a pop of green and extra burst of flavor.
How to Serve Baked Tortellini Casserole Recipe

Garnishes
A sprinkle of freshly chopped basil or parsley adds not only a lovely color contrast but also brightens up the rich flavors of the baked tortellini casserole recipe. For a little extra indulgence, sprinkle some crushed red pepper flakes or drizzle a bit of good quality olive oil just before serving.
Side Dishes
This dish is rich and filling, so pairing it with light, fresh sides is a winning idea. Consider a crisp mixed green salad with a simple lemon vinaigrette or garlic-roasted vegetables to complement the creamy casserole without overwhelming your palate.
Creative Ways to Present
Turn your Baked Tortellini Casserole Recipe into a fun party dish by serving it in individual ramekins or skillets. You can also layer it with extra cheese in a clear glass casserole dish to showcase those inviting layers. Add some toasted breadsticks or focaccia on the side for a complete Italian-inspired feast.
Make Ahead and Storage
Storing Leftovers
If you have leftovers, store them in an airtight container in the refrigerator. The flavors actually deepen after a day, making it a perfect next-day meal. Leftover Baked Tortellini Casserole Recipe keeps well for about 3 to 4 days.
Freezing
This casserole is a great candidate for freezing. Prepare the dish as usual but skip the final bake step. Cover tightly with foil or plastic wrap and freeze for up to 2 months. When ready, bake it straight from the freezer, adding some extra baking time until heated through and bubbly.
Reheating
Reheat individual portions in the microwave or warm the whole casserole in the oven at 350°F (175°C) until heated through. To keep it moist, cover it with foil. The cheese may get a little crispy around the edges, which adds a delightful texture contrast!
