Easy Chicken Tetrazzini
Easy Chicken Tetrazzini is one of those cozy casseroles that works especially well when you already have cooked chicken waiting in the fridge. Tender spaghetti and chicken are coated in a rich, creamy sauce, then topped with mozzarella and cheddar cheese and baked until hot and bubbly. It’s filling, family-friendly, and a great way to turn leftover or rotisserie chicken into dinner.
Just about any plain cooked chicken will work. You can use baked chicken, slow cooker chicken, leftover chicken breasts or thighs, or shredded rotisserie chicken. Chop or shred it before adding it to the sauce.
Yes. Assemble the casserole, cover it tightly, and refrigerate it until you’re ready to bake. Since it will be starting cold, it may need a little additional baking time. I would wait to bake it until shortly before serving for the best pasta texture.
Yes. Spaghetti is traditional for this recipe, but linguine, fettuccine, or another pasta with a similar texture can work. Short pasta such as penne or rotini can also be used. Cook whichever pasta you choose just until al dente before adding it to the casserole.
Yes. Let leftovers cool, then store them in an airtight freezer-safe container. Keep in mind that creamy pasta sauces can change slightly in texture after freezing and thawing.
Ingredient Notes
- Spaghetti: The pasta base for the casserole.

- Cream of chicken soup: Helps create the creamy sauce.
- Cream of mushroom soup: Adds another layer of savory flavor.
- Sour cream: Makes the sauce extra creamy.
- Butter: Adds richness to the sauce.
- Chicken broth: Loosens the sauce so it coats the chicken and pasta.
- Salt and pepper: For seasoning.
- Mozzarella cheese: Melts beautifully over the casserole.
- Cheddar cheese: Adds plenty of cheesy flavor.
- Parsley: Optional for a little color before serving.

I loved how easy this was. My family loved it.
Loved it! Will definitely make it again. Next time I’ll cut it in half though. The recipe was just too much for me and my husband. But, was delicious!
Could this be frozen?
I freeze chicken pasta recipes with no problem!
Could you keep this in the crock pot on warm , without the spaghetti getting mushy? Thinking of making this for Election Day to take for my Workers,do it would have to be in the crock pot from 5 am to 7 pm
That should work out ok Trudy. It really depends on how your “warm” setting runs.
I just made this tonight! I shredded my chicken after I baked it in butter and seasonings. I then shredded it and pan fried it. It was amazing will totally be a new favorite.
My chicken breast are defrosting right now. I have everything but sour cream so can I leave that out?
