My Kids Favorite Dinner, Maybe Ever!
There isn’t much better than pasta covered in a creamy cheese sauce (or mashed potatoes!), especially when the pasta is already stuffed with cheese.
When I was working on this casserole, I wanted to make it as easy as possible without cutting corners on the final dish. I didn’t want to boil a separate pot of tortellini, cook the broccoli in another pan, and then assemble everything before putting it back in the oven.
So I started testing it with the tortellini straight from the freezer and chopped the broccoli small enough to cook right alongside it. It worked perfectly.
From there, I added rotisserie chicken to keep things simple and made a quick homemade cheese sauce. And since a creamy casserole needs a little texture, I finish it with buttery toasted panko.
It ended up being a dinner my whole family devoured and I knew I needed to share!
Chicken Tortellini Casserole Ingredients
| Ingredient | Tips & Swaps |
|---|---|
| Frozen cheese tortellini | Use a 16-ounce package straight from the freezer. Don’t thaw or boil it first. |
| Rotisserie chicken | My favorite shortcut. Leftover cooked chicken works too. Chop it fairly small so you get chicken in every bite. |
| Broccoli | Cut it into very small florets so it becomes tender while the casserole bakes. |
| Sharp cheddar and parmesan | Sharp Cheddar gives the sauce more flavor than mild cheese. Freshly grated is best! |
| Sour cream | Makes the sauce creamy while adding a little tang to balance all the cheese. |
| Dijon mustard | You won’t taste mustard. It adds depth and helps balance the richness of the sauce. |
| Chicken bouillon | Adds a big boost of savory flavor. Since bouillon and Parmesan are both salty, season with additional salt at the end. |
| Panko breadcrumbs | Toast them in butter before adding them to the casserole for the best crispy topping. |

Storage
Leftovers?
- Preparing Ahead: Assemble the chicken tortellini casserole (save the panko topping) and refrigerate for up to 2 days. When ready, let it sit at room temp while preheating to 375°F. Add panko, cover with foil, and bake for 45-50 minutes until bubbly.
- Reheating: Cover leftovers with foil and bake at 375°F for 30 minutes, or microwave individual servings.
- Freezing: Assemble up to the panko step, cool, then wrap tightly. Freeze for up to 3 months.
What To Serve With Chicken Tortellini:
Chicken Tortellini Casserole
Ingredients
- 2 cups broccoli chopped into very small pieces
- 2 cups cooked chicken like rotisserie, chopped into small pieces
- 1 pound cheese-filled tortellini 16 ounces, frozen, not fresh or dried
- 3 tablespoons unsalted butter
- 1/3 cup all-purpose flour
- 1 cup milk 1%, 2% or whole; I use 1%
- 1 cup chicken stock or chicken broth
- 1 cup freshly shredded sharp Cheddar cheese
- 1 cup freshly grated Parmesan cheese divided
- 1/2 cup sour cream I use fat-free
- 2 teaspoons chicken bouillon powder
- 1-1/2 teaspoons Dijon-style mustard
- 1 teaspoon dried parsley flakes
- 1 teaspoon roasted garlic powder
- 1/4 teaspoon granulated onion
- Salt and pepper
- 2 tablespoons unsalted butter
- 3/4 cup panko breadcrumbs next to breadcrumbs
Instructions
- Preheat oven to 375°F. In a 9×13-inch baking dish, combine chopped broccoli, chicken, and frozen tortellini (no need to thaw). Toss everything together.
- Melt 3 tablespoons butter in a small pot over medium heat. Once melted, gradually add in flour, while whisking constantly, until a thick paste forms. Whisk for 1 minute to cook out the raw flour taste, then gradually add in 1/3 cup of the milk while whisking constantly. Gradually add 1/3 cup chicken stock while continuing to whisk. Add in another 1/3 cup milk, another 1/3 cup stock, remaining 1/3 cup milk, and remaining 1/3 cup stock. Whisk after each addition until completely smooth and sauce is thickened.
- Add sharp Cheddar and 1/2 cup Parmesan and whisk until completely smooth. Add sour cream and whisk again until smooth. Stir in the chicken bouillon powder, Dijon mustard, dried parsley, garlic powder, granulated onion, and salt and pepper to taste. (I add 1/2 teaspoon salt and 1/4 teaspoon pepper; add to taste preference—the Parmesan cheese adds a good amount of saltiness.)
- Pour the sauce over everything in the casserole dish and toss ingredients to coat evenly. Make sure the tortellini is covered with the sauce. Sprinkle remaining 1/2 cup Parmesan over the casserole. Cover with foil and bake for 30 minutes.
- Meanwhile, in a saucepan over medium-high heat, melt the 2 tablespoons butter for the topping. Add the panko and toast, stirring constantly, until panko is light brown and toasted. After casserole has baked for 30 minutes, remove and sprinkle the topping evenly over the cheese. Bake, uncovered, for another 8–10 minutes or until warm and bubbly. Remove and serve hot.

Delicious!
This recipe is definitely a keeper!
SO happy to hear this! 🙂
Can u use fridgerated tortellini???
I haven’t tested this recipe with refrigerated tortellini, sorry!
I made it tonight with refrigerator tortellini and it was perfect. I followed the recipe exactly and it tasted the same as when I’ve used frozen.
Amazing, it has just become a regular in our home
I am so happy to hear this! Thanks Jaynie! 🙂
10/10!! I accidentally put all the Parmesan into the sauce but it still turned out great thankfully. Fed 4 people and the pan was totally empty by the end.
Made this a few nights ago and it was delicious! Like an extra special mac and cheese.
I found this recipe when I was looking for something different for my husband who has pretty severe GERD. I was tired I grilled chicken and fish. This was just what we needed! It had so much flavor and so easy! Definitely going into our rotation ❤️
excellent recipe except i would not get rotisserie already cooked chicken. i cooked in my air fryer b4 baking drying it out too much. i imagine small cut up bits of uncooked chicken would be better also the sauce was cooked out with 40min baking. i would make a little more sauce and add it last 10 minutes.
I made this tonight and the flavors were on point but my tortellini was too hard. Any suggestions?
Did you use frozen tortellini? Or fresh?
How would you recommend adapting this recipe using fresh tortellini instead of frozen?
Thanks! 🙂
I have made it a few times with frozen. Tonight I only had fresh so I tried it. I didn’t change a thing and it turned out perfectly. I thought it might be mushy but it wasn’t at all.
I am so happy to hear this! Thanks Kay! 🙂
