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

IngredientTips & Swaps
Frozen cheese tortelliniUse a 16-ounce package straight from the freezer. Don’t thaw or boil it first.
Rotisserie chickenMy favorite shortcut. Leftover cooked chicken works too. Chop it fairly small so you get chicken in every bite.
BroccoliCut it into very small florets so it becomes tender while the casserole bakes.
Sharp cheddar and parmesanSharp Cheddar gives the sauce more flavor than mild cheese. Freshly grated is best!
Sour creamMakes the sauce creamy while adding a little tang to balance all the cheese.
Dijon mustardYou won’t taste mustard. It adds depth and helps balance the richness of the sauce.
Chicken bouillonAdds a big boost of savory flavor. Since bouillon and Parmesan are both salty, season with additional salt at the end.
Panko breadcrumbsToast them in butter before adding them to the casserole for the best crispy topping.

    Chicken Tortellini Casserole

    This Chicken Tortellini Casserole combines delicious cheese-filled tortellini pasta, tender bites of chicken, and fresh broccoli, tossed in a cheesy sauce and baked until hot and bubbly. This easy casserole is comforting, flavorful, and satisfying.
    Prep Time: 25 minutes
    Cook Time: 37 minutes
    Total Time: 1 hour 2 minutes
    Servings: 6 servings

    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
    Topping
    • 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.
    Final step! Please let us know how it was by leaving a review.

    Recipe Notes

    Storage: Store leftovers in an airtight container in the fridge for up to 3 days. Reheat in the microwave or oven until warmed through. If the sauce thickens, stir in a splash of milk before reheating.
