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 during the middle of a busy week.

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.

  1. Boil the spaghetti. Bring a large pot of water to a roaring boil and add salt. Add the pasta, and drain it 2 minutes earlier than is suggested on the box.
  2. Make the sauce. Start by sauteing the mushrooms in butter. Then you will be adding flour and to create a roux. (Read more about rouxs below.) Finally you will add in chicken stock, milk, and spices.
  3. Finish off the sauce. After simmering for 5 minutes add cheese and sour cream.
  4. Combine the remaining ingredients. Mix everything together in the casserole dish, top with more cheese and then bake for 30 minutes.

Making a Roux

I use rouxs in a lot of my recipes. It is such a great kitchen skill to have learn and practice. A roux is a thickening agent made from flour and fat. It is the back bone of cream sauces. The fat coats the flour, suspending it in the sauce and prevents 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. This results in a rich and creamy sauce.

It is the same technique used in my Homemade Condensed Cream of Mushroom Soup, which can be used as a substitute here. 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.

Keeping Cooked Chicken on Hand

One of my favorite hacks is to keep cooked shredded chicken in my freezer. It is a lifesaver for dishes like this or my Chicken Noodle Casserole. Follow the steps below and you can always have chicken on hand.

How to Cook Chicken

  1. Place boneless skinless chicken breasts in a saucepan and cover with water.
  2. Bring to a boil and cook for 4 to 7 minutes or until the chicken registers 165 Fahrenheit.

Freezing Shredded Chicken

You can always have chicken on hand by freezing it after cooking it. This works great with the above method, and also with a store-bought rotisserie chicken.

  1. Line a baking sheet with wax paper.
  2. Add the shredded chicken in a single layer and freeze for one hour.
  3. Break up and put in a ziplock bag, putting it back in the freezer for up to 3 months.

Using this method, it will be easy to pull out just a few cups of chicken at a time. The chicken thaws in the refrigerator overnight before using, or quickly on the counter top. I have even thrown it into soups straight from the freezer.

Freezing Cooked Chicken

Freezing cooked chicken to keep on hand is the perfect short cut for dinners during a busy weeknight! Learn how to freeze cooked chicken with these simple easy steps.

Using Other 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 2 minutes less than is listed on the package, as the noodles will continue cooking in the casserole.

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. Here are a few tips:

  1. Make the recipe in a disposable casserole dish to avoid it breaking when it goes from the freezer to the hot oven.
  2. Make the recipe as directed, stopping before you put it in the oven.
  3. Wrap it three times with aluminum foil or plastic wrap.
  4. Store it in the freezer for up to three months.
  5. Unwrap before baking.
  6. Bake right from frozen at 350 degrees for 45 to 55 minutes or until the casserole is bubbly and golden brown.

What to Serve with Chicken Tetrazzini

Here are a few recipes that would go great with this delicious casserole.

  • My roasted broccoli is a great way to add in some vegetables to this recipe.
  • A simple chopped salad is fantastic to go with a pasta dish.
  • I adore this creamed spinach recipe and its a great way to add some veggies to dinner.

    I used to make a version of this, long ago. But l used only turkey breast to “escape” from the chicken routine. In addition to the mushrooms, l also sautéed onion, celery, and garlic. Occasionally, l also included green peas for color and vegetables, making this a one-dish meal.

    I made this, halved, and it made enough for 4 people. Followed recipe, using Costco rotisserie chicken, to the the letter except I added some frozen peas. Sauce is delicious, better than taking the cream soup route which many recipes call for. I will definitely be making this again.

    It’s in the oven right now!!! Could have eaten it before baked! This is different from other chicken tet recipes and we like this much better! Maybe it’s the types of cheese… others has used Velveeta, but I don’t use Velveeta anymore. At the last minute I added some spinach to it! Yumm!!!

      I’m so happy that you loved it!

    I added about a quarter cup sherry to sauce. I needed to because I used homemade stock which I did not chill to take the fat off. So tasted a bit oily. Sherry cut that. So good!

    Hi I love your recipes. How do I find the nutritional information. I’ve tried hitting the arrow both up and down, neither provide any information. What am I doing incorrectly?

    • Lisa Longley says

      I apologize. It is in there now. Some of our older recipes just don’t have it in there and it still needs to be added. Thank you for bringing this to my attention!

    I have been receiving your emails for at least a year, saving many in a folder until felt ready to cook like I used to, until I got the email with this recipe, it just spoke to me. LOL I guess it is because this was unlike anything my mother ever made. We were a steak and potatoes family.
    Today I made this recipe, and I love it! It is a comfort food that needs to come with a warning. It is very filling so when going back for seconds people need to be aware of how big that second portion is. Or, they can wear sweatpants.
    If I could suggest one thing, the recipe calls for 2 cups of mozzarella divided but in
    steps 6 and 7 both steps say 2 cups of mozzarella. So I was afraid I didn’t have enough cheese. given how the sauce tastes, I can only assume it is a typo. but an inexperienced cook may not understand and add way more cheese than what is called for. As a cheese lover, I don’t mind a bit extra but 4 cups of cheese would ruin this dish.
    Also, the amount of ads made reading this extremely difficult, and writing this ridiculous.


    • Lisa Longley says

      I’m so glad you enjoyed this! The way the software works, it only allows for you to pull in the amount called for in the recipe into each step, if that makes sense. But I can clarify in the step itself that it is one cup here, and one cup there. As for the ads, I can appreciate your annoyance, and at the same time, the only way I’m able to provide free recipes to readers is through having ads on my website.
