This chicken tetrazzini is spaghetti, mushrooms, peas, chicken and cheese, all tossed together in a homemade creamy sauce and baked to perfection. The ultimate comfort food classic that’s perfect for feeding a crowd!
When I’m looking for a dish that I know will please both kids and adults, I turn to baked pasta recipes such as buffalo chicken pasta, pasta al forno and this easy and delicious chicken tetrazzini.
Chicken and pasta are always a winning combination in my book. Whenever I have leftover chicken on hand, I put it to good use in this creamy, cheesy chicken tetrazzini.
Why is it called chicken tetrazzini?
Chicken tetrazzini is named after the Italian opera singer Luisa Tetrazzini, but is actually a dish that originated in America. This recipe features chicken and pasta in a creamy sauce, often with the addition of mushrooms and sometimes peas. The dish is finished off with either a layer of breadcrumbs or melted cheese.
How do you make chicken tetrazzini?
Start by cooking onions, mushrooms and garlic with butter. Whisk in flour, then add half and half and chicken broth to form the base of the sauce. Next, stir in cream cheese and parmesan cheese, along with some seasonings. Place spaghetti in a bowl along with chicken, the mushroom sauce and peas. Toss until everything is well combined, then place the pasta mixture in a baking dish. Add a layer of buttered breadcrumbs, then bake until everything is hot and the sauce is bubbly. Add a sprinkling of fresh parsley, then serve and enjoy.
Tips for the perfect pasta dish
- You can use any type of cooked chicken in this recipe – diced roasted chicken, shredded chicken, leftover chicken or even rotisserie chicken. They all work just fine!
- This casserole can be assembled up to 8 hours before you plan to bake it. Store the covered pan in the fridge, then bake for an additional 10-15 minutes to compensate for starting with a cold dish.
- While I typically use button mushrooms, other varieties also work such as cremini, portobello or chanterelle. Buy pre-sliced mushrooms to save on prep time.
- No need to thaw your peas before you mix them into the pasta, they’ll cook through in the oven.
- This dish will stay fresh in the refrigerator for up to 4 days, and can be frozen for 2 months. Reheat any leftovers covered in the oven, or heat individual portions in the microwave.
Flavor variations
This is a classic version of chicken tetrazzini, but you can absolutely add other ingredients to customize the flavors to your tastes.
- Protein: Instead of diced chicken, try ground chicken, sliced steak, turkey or sliced smoked sausage.
- Pasta: Spaghetti is traditional in this dish, but you can also use linguine, fettuccine, penne, farfalle or even macaroni.
- Add-Ins: You can add a variety of ingredients to this recipe such as sauteed bell peppers, green beans, bacon, kale, spinach or olives.
- Toppings: Instead of Italian breadcrumbs, try panko breadcrumbs, or skip the bread and add a layer of shredded mozzarella cheese instead.
Chicken tetrazzini is a popular dish for good reason – it’s loaded with flavor and is always a hit!

Have you tried to his with zoodles? Wondering how that would turn out to cut out some carbs!
The only thing to consider is that the zoodles may release a lot of liquid as they bake!
