I have always wanted to learn how to make chicken tetrazzini for our recipe vault, that is this blog. So glad I finally tried this dish. Everyone in the family loved it.
Its a really yummy comfort food dinner that, with a few adjustments becomes a healthier comfort food dinner than you would first suspect.

The adjustments I made were less cheese and salt, and the results were still fabulous.
How to make Cheesy Chicken Tetrazzini?
- Preheat oven to 350 degrees.
- Add 2T butter to a large saucepan on medium-high heat. After butter melts, add mushrooms and ¼ cup chicken stock. After about 10 minutes, the mushrooms should be nicely browned and the liquid should have mostly evaporated.
- While mushrooms are cooking, tear thin spaghetti noodles in thirds and place in boiling water. Cook for about 5 minutes.
- Remove mushrooms from saucepan, and set aside.
- Return pan to heat and add 6T butter. Melt butter, then whisk in flour for about one minute.
- Slowly mix in chicken stock and milk. Cook over medium-high heat until bubbly. Cook for additional 2 minutes once bubbly.
- Add in ¼ cup shredded parmesan and ¼ cup shredded mozarella, stir. Once cheese is melted add in chicken, mushrooms, salt and pepper.
- Add chicken/milk/mushroom mixture to noodles and stir.
- Scoop into 13x9 baking dish and cover with 1 ½ cups shredded mozzarella.
- Cook for 30 minutes in preheated oven. Enjoy!

Tips for this easy cheesy chicken tetrazzini:
- Use rotisserie chicken for a faster prep time. You only need 2 cups of shredded rotisserie chicken for this dish, and you can usually get just a little more than 2 cups from one chicken, so its perfect.
- If you do not have shredded parmesan on hand, this dish works great with only mozzarella. We've cooked it this way, and it's still amazingly delicious.
- If you would like to add another vegetable besides mushrooms, you can try broccoli or green beans cut short.
- Be sure to tear the thin spaghetti noodles in thirds. This size of noodle works really well for this dish.
What to serve with Chicken Tetrazzini?
This is a good size chicken tetrazzini for a crowd. The dish is rich, but not too rich. You can cut a small to medium size piece for one person and it will most likely be enough, especially when combined with a healthy side. You can serve 10-12 people with this recipe. Here are some side ideas:
- Large Green Salad
- Sauteed zucchinis
- Sauteed spinach
- Roasted Broccoli
You should make this tonight. It's so good.
