Chicken and Sausage Tortellini Casserole

What I Love About My Cheesy Tortellini Bake
This casserole brings together everything I love about Italian comfort food, from the savory sausage to the four melty cheeses.
- One dish, minimal cleanup: I brown the chicken and sausage, build the sauce, and toss everything together in the same pan and bowl. That means only one casserole dish to wash at the end.
- Big flavor from a shortcut sauce: I boost a jar of three-cheese pasta sauce with fresh basil, brown sugar, and a pinch of red pepper flakes. It tastes like it simmered for hours.
- Four cheeses, four jobs: I stir Asiago, Parmesan, and Romano straight into the sauce for sharpness. Then I finish with a blanket of mozzarella that turns golden and bubbly on top.
- Feeds a crowd and reheats well: This casserole holds up for game nights, potlucks, or a week of easy lunches.
Key Ingredient Notes
- Ground Italian sausage: I use mild sausage to keep this kid-friendly, though spicy works too if you want more heat. Either way, look for one seasoned with fennel and garlic, the classic Italian sausage flavor this casserole is built around.
- Refrigerated cheese tortellini: Refrigerated tortellini is already tender and cooks quickly, which is what this casserole’s quick bake depends on. A spinach and cheese tortellini is a good swap if you want a little extra color.
- Three-cheese pasta sauce: A jarred three-cheese pasta sauce gives this casserole a head start on flavor, since it’s already got cheese built in. Pick one you’d be happy eating on its own, since it’s the base of the whole dish.
- Vidalia onion: Its natural sweetness balances the acidity in the tomato sauce without adding a sharp onion bite.
- Brown sugar: Just a small amount rounds out the acidity in the tomato sauce. It’s not enough to make the dish taste sweet, just balanced.
- Asiago, Parmesan, Romano, and mozzarella: I mix the first three cheeses straight into the sauce for sharpness and depth. Then I save the mozzarella to melt on top. Grating your own cheese off the block gives the smoothest melt, since pre-shredded bags contain anti-caking additives that affect texture.

How to Make Chicken and Sausage Tortellini Casserole
- Boil the tortellini. Cook it in salted water until just al dente, then drain and set it aside in a large mixing bowl. Undercooking it slightly here keeps it from turning mushy once it goes back in the oven.
- Prep the chicken and sausage. Cut the chicken breast into small, even chunks and roll the ground sausage into small balls. Keeping the pieces similar in size helps everything cook through at the same rate.
- Brown the meat. Heat oil in a large pan over medium heat. Cook the chicken and sausage with a little salt until done. Transfer the meat to the bowl with the tortellini and keep the drippings in the pan.
- Build the vegetables. Dice the tomatoes and onion and add them to the same pan you used for the meat. Sautéing them right in those drippings for a few minutes builds a lot of flavor.
- Add the garlic. Stir in the crushed garlic and cook for about a minute, just until fragrant.
- Simmer the sauce. Pour in the pasta sauce, minced basil, brown sugar, salt, and red pepper flakes. Bring it to a simmer, then take it off the heat once everything is well combined.
- Preheat and prep the dish. Preheat the oven to 350°F and lightly grease a 1.5 to 2 quart casserole dish.
- Combine everything. Add the Asiago, Parmesan, and Romano cheeses to the bowl with the meat and tortellini. Pour in the sauce and mix until everything’s evenly coated.
- Assemble and bake. Spread the mixture into the prepared casserole dish, top with mozzarella, and bake for about 15 minutes. Since everything is already cooked, this bake is really just to melt the cheese. Watch it rather than going strictly by the clock.
- Serve. This casserole is best served right away, while the cheese is still bubbly. The tortellini hasn’t had a chance yet to soak up too much sauce.

Ways to Serve Chicken Sausage Tortellini Bake
- Crusty bread for scooping: A loaf of crusty Italian bread works great for scooping up the sauce. My homemade Parmesan garlic and herb breadsticks are another good option.
- A peppery green salad: A Caesar salad or a simple arugula salad with lemon cuts through the richness of all that cheese.
- Roasted vegetables: My roasted green beans and mushrooms or garlic butter roasted Brussels sprouts add color and a fresh bite next to all the cheese and pasta.
- A glass of red wine: A medium-bodied red like Chianti, Sangiovese, or Barbera pairs naturally with the tomato and Italian sausage flavors here.
How to Store, Freeze, and Reheat Chicken and Sausage Tortellini Casserole
- Store: in an airtight container in the refrigerator for 3 to 4 days.
- Freeze: I don’t recommend freezing this casserole. The tortellini is already fully cooked before it goes into the oven. Freezing and thawing already-cooked pasta tends to turn it mushy.
- Reheat: individual portions in the microwave in 30-second increments, or warm larger portions in a covered pan over medium-low heat. Either way, heat it until it’s steaming hot before eating.
Chicken and Sausage Tortellini Casserole Recipe FAQs
Refrigerated cheese tortellini is my go-to for this casserole since it’s already tender and cooks quickly in the oven. A spinach and cheese tortellini is a good swap if you want a little more color and flavor.
In this recipe, the tortellini needs to be boiled first. The casserole only bakes for about 15 minutes, just long enough to melt the cheese and heat everything through. That’s why the pasta has to already be cooked before it goes in the oven.
Since everything is fully cooked before baking, this casserole is easy to assemble ahead of time. I’ve covered and refrigerated it a few hours before dinnertime. Since it starts cold, I add a few extra minutes to the bake time. I haven’t tested holding it overnight, so I’d stick with same-day prep for the best texture.
A jarred three-cheese pasta sauce is what I use here, since it already carries plenty of cheesy flavor. A good marinara or homemade tomato basil sauce works well too if that’s what you have on hand.
