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 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.

This recipe looks awesome. Can’t wait to try it.
One question… The calorie count, is that for the whole recipe or per serving?
Per serving. I hope you love it Sheryl!
How did you cook the chicken? Bake or boil it?
You can use whatever cooked chicken you have on hand. I usually make a batch in my crockpot, or bake it.
Can you freeze this
Do you cover dish while baking?
No you do not.
Can you just throw everything in the crockpot and cook it? Adding noodles in later of course.
I’ve made it both in the oven and the crockpot and both turned out well! Great recipe!
What crockpot setting did you use and for how long? Want to make this tomorrow, but don’t want to use the oven. I live in Palm Springs. Too hot!
