How to Make Turkey Tetrazzini
- Cook pasta. Cook pasta al dente, according to package directions. Then drain the pasta, reserving 1/2 cup pasta water.
- Make the sauce. Melt the butter over medium-heat in a skillet. Add in the chopped onions and cook for 3 to 5 minutes. Then add minced garlic and cook an additional minute. Next add in the turkey, cream of mushroom soup and sour cream. If you need to thin the sauce out a little, add in the pasta water.
- Combine. Toss together the sauce and noodles, then pour mixture in a buttered 8×8″ baking dish.
- Bake in the oven. Top with cheese and bake in oven at 350°F for 25-30 minutes, or until the top is bubbly and lightly golden.
Tips and Substitutions
This tetrazzini casserole dish is perfect for using leftovers and having an extra meal during the week.
- Use homemade cream of mushroom soup if you’d prefer to make your own.
- Add in 1/2 cup sliced mushrooms with the chopped onions.
- You can also use cooked chicken instead of turkey for a chicken tetrazzini.
- For more texture, feel free to sprinkle some bread crumbs on top. We love the crunch from Panko breadcrumbs.
- You can substitute chopped onions and minced garlic with 1/2 teaspoon both onion powder and garlic powder. Simply mix the seasonings with the melted butter.
- Frozen peas also taste yummy in this dish. Mix them in when you stir together the sauce and noodles.

Recipe FAQs
Tetrazzini is an American dish that is made with diced meat or seafood. It is known to have been originated in San Francisco. The dish is named after the famous opera singer Luisa Tetrazzini. It usually has a buttery cream sauce with mushrooms and topped with cheese.
We love to serve this pasta dish with a big chopped salad and leftover dinner rolls or French bread. Seriously so yummy!
Store leftovers for up to 3-4 days in an airtight container in the refrigerator. You can also freeze leftovers, cool completely then store in an airtight container for up 3 months. Thaw in the fridge, add additional milk, heavy cream or chicken broth when reheating.
This dish makes a great freezer meal. Sometimes I double the recipe and pop one in the freezer for busy weeknights.
To freeze before baking, mix together the noodles with the sauce, then pour into a buttered baking dish. Let cool completely, then add cheese on top. Cover tightly with foil or lid and place in the freezer. Thaw in fridge overnight, then bake in oven at 350°F according to directions.

Can this be made without the sour cream? I don’t have any.
It will change the texture, but you could try whisking in some greek yogurt, heavy cream or milk if you don’t have any.

I love this recipe and have made it 4x for myself and others. I did add a jar of sliced mushrooms like was recommended at the end of the recipe and I don’t use as much garlic as recommended – about 1/4 of a teaspoon.
