What Is Chicken Tetrazzini?
Chicken Tetrazzini is an American casserole dish with several different variations, but it’s often made with some type of poultry like chicken or turkey, mushrooms and pasta in a creamy, buttery sauce and often topped with cheese.
Ingredients Needed
Here's what you'll need to make this ridiculously delicious chicken tetrazzini recipe:
- Chicken Breasts: I’m a chicken breast kind of girl so I prefer using shredded chicken breasts in my chicken casserole, but feel free to use chicken thighs or even a rotisserie chicken to make it really easy.
- Celery, Bell Pepper and Onion: A combination of chopped celery, green bell pepper and onion (often called the Holy Trinity of vegetables) adds the foundation and gives this recipe tons of flavor!
- Cream of Mushroom and Cream of Chicken Soup: Grab a can of both to add more flavor and a creamy texture to the casserole.
- Egg Noodles: My pasta of choice for this dish is egg noodles, but spaghetti pasta will also work just fine.
- Chicken Broth: Chicken broth is needed for extra moisture, flavor, and to help the ingredients come together.
- Sharp Cheddar Cheese: Definitely don't skip the cheese at the end and make sure it’s sharp cheddar cheese.
- Salt & Pepper: Just a little bit of seasoning is all you'll need since the recipe will have lots of flavor from the rest of the ingredients.
How To Make Chicken Tetrazzini
The full instructions are included in the recipe card below, but here’s a quick overview:
Step One: Boil your chicken breasts using the slow-boil method. This is a proven way to get the most tender, fall apart chicken breast meat. You can get the full instructions + a step-by-step video on how to properly boil chicken breasts here.
Step Two: In a really large bowl add cooked egg noodles, finely chopped veggies, shredded cooked chicken breast meat and the remaining ingredients (except the cheese). Gently mix everything together.
Step Three: Add everything to a buttered 9x13 casserole dish, bake in the oven until bubbly and lightly brown on top. Add the shredded sharp cheddar cheese during the last 5-10 minutes of cooking.
Step Four: Remove the casserole from the oven and allow it to rest for 5-10 minutes. Enjoy by itself or with your favorite salad!
Recipe Tips!
- Don’t forget to salt your water when boiling your egg noodles. It helps add flavor to the pasta while it's cooking.
- Short on time? Grab a cooked rotisserie chicken from your local grocery store. Pull apart the meat and shred it with a fork or your hands. Just make sure to get one without bold flavors so it doesn’t overpower the dish. I usually go for a lemon-pepper chicken or something similar when using this method.
- Don’t skip the sharp cheddar cheese at the end. It gives the casserole a rich flavor and extra goodness.
