What is Chicken Tetrazzini Made of?
Chicken Tetrazzini is a classic American dinner recipe that is made with diced chunks of chicken breasts, mushrooms, and pasta in a creamy parmesan sauce! Over time there have been many adaptations of this recipe and some people turn it into a baked casserole, add diced tomatoes, or top it with sliced almonds.
My version is very similar to the classic, but with a much easier to make sauce! The noodles cook with the chicken and mushrooms in one pan. The remaining starchy liquid from the spaghetti makes for the base of the creamy and cheesy tetrazzini sauce!
How to Make One Pot Chicken Tetrazzini:
- The first thing to do is to heat a large soup pot, dutch oven, or deep skillet with olive oil over medium-high heat.
- Once your oil is warm, you can add your cubed chicken, sliced mushrooms, diced onion, and seasonings to the pan and cook for about 5-7 minutes.
- Once the chicken is seared on all sides and the vegetables are soft you will turn your heat to medium-low and add in your chicken broth and spaghetti noodles. I find it easiest to break the spaghetti noodles in half first.
- Now, the chicken mixture will simmer for 10-12 minutes until the noodles are soft. You will want to stir the pasta around with tongs every couple of minutes to make sure the spaghetti is all submerged under the broth, and that it doesn't stick to the bottom of the pan.
- After your spaghetti is cooked, remove your pan from the heat and turn the stove off. There will be some liquid left in the bottom of the pot, that is ok, that's what helps turn the cheese into a sauce!
- Add the cream cheese, parmesan, and parsley if using. Toss the pasta around with tongs until the cheese is melted.
- If desired, cover the tetrazzini and allow it to stand for 3-5 minutes until sauce thickens up more, stir before serving.
