Chicken Spinach Rigatoni is an ultra creamy and rich pasta casserole with tons of gooey cheese. So good, the kids won’t mind the spinach!

Super Creamy Pasta Casserole

A container of chive and onion cream cheese plus some heavy cream creates a super creamy base for this casserole. It’s a rich and indulgent recipe so a little goes a long way and you will probably want to serve it with something light like a salad.

How To Make Chicken Spinach Rigatoni

More detailed directions in recipe card below.

Cook the pasta.

Make the sauce. Cook some onion in butter until soft. Add the cream cheese and heavy cream and cook until cream cheese is melted. Stir in salt, pepper, crushed red pepper flakes, diced tomatoes, chicken, and spinach.
Assemble. Mix in the pasta and half of each cheese. Transfer to a greased 9×13-inch baking dish. Sprinkle remaining cheese on top.

Bake. Bake for 20 minutes or until hot throughout.

Recipe Tips

Be sure to add salt to the pasta water. This is the number one way to ensure your casserole does not turn out bland.

Only cook the pasta to al dente. It will cook a little more in the oven and you don’t want it to get mushy in texture.

You can use rotisserie chicken or any leftover chicken for this recipe.

Variations and Substitutions

Use another pasta shape. Penne, ziti, and cavatappi work well.

Add a few minced garlic cloves or some garlic powder.

Add a few sun-dried tomatoes.
