In the never-ending quest to find recipes that my family can come together around the table and enjoy, I have a delicious casserole for you. This Chicken Tetrazzini is always a big hit with my whole family.

This recipe is easy to follow and results in a creamy noodle casserole. Big warm bowls of this chicken tetrazzini casserole are bite after bite of comfort.

One of my favorite things about this recipe is that you can prepare the whole thing the night before and then put it in the oven when you get home from work. You could even freeze this noodle dish and pull it out in the middle of a busy week.

I made this last week for dinner and it was INCREDIBLE!!! Thank you for this recipe, it will be made again and again at our house!

How to Make Chicken Tetrazzini

While this is an easy recipe, it does involve a few moving pieces, so I suggest reading this brief overview. Get the full ingredients and instructions at the bottom of the post.

Boil the Spaghetti

Bring a large pot of water to a roaring boil and add salt. Add the pasta, and drain it two minutes earlier than is suggested on the box.

Make the Sauce

Start by sauteing the mushrooms in butter. Then you will be whisking in flour to create a roux. Finally, you will add in chicken stock, milk, and spices.

Finish off the Sauce and Put it All Together

After simmering for five minutes, add cheese and sour cream and stir to combine. Mix everything together in the casserole dish, sprinkle the top with more cheese, and then bake for 30 minutes.

Tips and Tricks

  • Making a roux: A roux is the backbone of cream sauces. The fat coats the flour, suspending it in the sauce and preventing the sauce from separating when it is hit with high heat on the stovetop or in the oven. In this recipe, we combine the butter we used to sauté the mushrooms with flour. Then we add chicken stock and milk slowly at first (about two tablespoons at a time) and then more quickly.
  • Using cream of mushroom soup: If you want to use store-bought canned soup instead to speed things up, you will want to leave out the butter, mushrooms, flour, chicken stock, and milk. (I recommend still using the seasonings.) Replace them with two 10-ounce cans.
  • Using different noodles: You will notice that in my Turkey Tetrazzini we use egg noodles. For this one, I decided to go with spaghetti. You really can use any noodle you like. Just make sure that you cook for two minutes less than is listed on the package, as the noodles will continue cooking in the casserole.
  • Using cooked chicken: This recipe does call for cooked chicken and I have listed in the notes of the recipe card three methods: cooking it on the stovetop, using an instant pot to cook it, or using a rotisserie chicken from the store. I also love keeping shredded chicken in my freezer , just thaw in the refrigerator before overnight before making this.

Storing Leftovers

Leftovers can be stored in an airtight container in the refrigerator for up to four days. Reheat in the oven in a covered dish for 40 minutes, at 350 degrees Fahrenheit. You may need to add some milk or chicken stock so that it doesn’t dry out.

Making Ahead

My recipe for chicken tetrazzini is great to prepare the night before. Just wrap it in aluminum foil and put it right in the preheated oven when you are ready to eat. It will take a few extra minutes (5 to 10) to cook, but will be delicious. Store the uncooked recipe in the refrigerator for up to 24 hours before baking.

Freezing Chicken Tetrazzini

This is also a great recipe to make and stick in your freezer for a busy day. I like to store freezer casseroles in a disposable baking dish. Wrap it very well and store it in the freezer for up to three months. Thaw in the refrigerator overnight and then bake the following night, keeping in mind you will need to add a little bit of time as it will be going in the oven cold.

  • A simple chopped salad is fantastic to go with a pasta dish.
  • I adore this creamed spinach recipe and it’s a great way to add some veggies to dinner.
