This is an oldie but goodie family recipe that my mom shared with me years ago. It’s creamy, a little cheesy and packed with tender chicken breast meat. It’s hands down one of my favorites and the best part is it makes a lot! So there’s always leftovers.
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 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.
