Chicken Tortellini Casserole

When dinner needs to be comforting and easy, this Chicken Tortellini Casserole checks all the boxes. It’s creamy, cozy, and made with cheese tortellini, tender chicken, and a rich Alfredo-based sauce that bakes up bubbly and golden.

Everything gets stirred together in one bowl and baked until perfectly melty, making this a great option for busy weeknights or low-effort family dinners. Add a simple salad and some garlic bread, and you’ve got a meal that feels a little special without a lot of work.

This is one of those dinners I make when I don’t feel like cooking, but still want something warm and comforting on the table. It looks like you put in way more effort than you actually did — my favorite kind of recipe.

Why This Chicken Tortellini Casserole Works

• Creamy and comforting. Cheese tortellini, ricotta, and Alfredo sauce bake into a rich, cozy casserole that feels like comfort food done right.
• Minimal prep. Everything gets stirred together in one bowl before baking — no complicated steps or extra dishes.
• Family-friendly. Mild flavors, cheesy goodness, and tender chicken make this a dinner everyone will eat.
• Flexible. It works with rotisserie chicken, leftover chicken, or even different sauces if that’s what you have on hand.
• Perfect for busy nights. From fridge to oven to table with very little effort.

Ingredients You’ll Need

For specific amounts, please refer to the printable recipe card at the bottom of the post.

Pasta & Protein
Fresh cheese tortellini and cooked chicken make up the base of this casserole. Rotisserie chicken works great here and keeps prep to a minimum.

Creamy Sauce
Alfredo sauce and ricotta cheese combine to create a rich, creamy base that coats every bite.

Flavor & Greens
Fresh spinach adds a pop of color and helps balance the richness of the sauce.

Topping
Shredded mozzarella cheese bakes up bubbly and lightly golden on top.

Simplified Directions

When you are making this recipe, you’ll want to use the full recipe at the bottom of the page.

Stir the tortellini, chicken, Alfredo sauce, ricotta, and spinach together in a large bowl until everything is evenly coated. Transfer the mixture to a prepared baking dish, sprinkle with mozzarella, and bake until hot, bubbly, and lightly browned on top. Serve warm.

I’ve tried mixing everything directly in the baking dish, and let’s just say… it wasn’t my best idea. Using a bowl first makes this recipe much easier (and a lot less messy).

Substitutions & Variations

• Switch the sauce. Tomato-based sauces work great if you want to change things up.
• Change the cheese. Cottage cheese is a good substitute for ricotta.
• Add extra flavor. A little garlic, fresh basil, or a pinch of red pepper flakes adds a nice boost.
• Make it bigger. This recipe doubles easily and fits perfectly in a 9×13-inch baking dish.

How to Store Chicken Tortellini Casserole

Refrigerator:
Let the casserole cool completely, then store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat in the oven or microwave until warmed through.

Freezer / Make-Ahead:
This casserole freezes well. Assemble it in a freezer-safe dish without baking, cover tightly, and freeze for up to 3 months. Bake straight from frozen, loosely covered, until hot and bubbly, then uncover to finish baking.

This is one of those casseroles that reheats really well, which makes leftovers something to actually look forward to instead of forget about in the fridge.

Frequently Asked Questions

Can I use frozen tortellini instead of fresh?

Yes. Frozen tortellini works, but you’ll need to add extra baking time. If the cheese starts to brown too much, loosely tent the dish with foil.

What kind of chicken works best?

Any fully cooked chicken works here. Rotisserie chicken is the easiest option, but leftover chicken or cooked chicken thighs are great too.

Can I make this casserole ahead of time?

Absolutely. Assemble the casserole, cover tightly, and refrigerate for up to 24 hours before baking.
