- Chicken: I used boneless, skinless chicken breasts, but thighs or tenders will also work.
- Mushrooms: I like sliced cremini mushrooms, but white button or portabello mushrooms also work.
- Onion: Adds an earthy and sweet flavor.
- Garlic: Adds an earthy flavor and a pungent aroma.
- Italian Seasoning: A blend of herbs that adds depth to the dish.
- Salt + Pepper: Enhances the natural flavors of the dish.
- Chicken Broth: Creates a savory, umami base for the sauce.
- Cheese: Cream cheese, mozzarella, and Parmesan make this dish ultra gooey, creamy, and cheesy.
- Pasta: I like to use spaghetti, but any long pasta shape will work.
- Parsley: Adds a pop of color and freshness.
Pro Tip: Try adding some caramelized onions for even more flavor!

While the two dishes seem similar, they have different tastes. Chicken spaghetti has a Southwestern flair from the tomatoes and green chilies and cheddar cheese. Tetrazzini is much milder in flavor.
This dish is named after the Italian opera star Luisa Tetrazzini and was created by the lead chef at the hotel in San Francisco where she made her American debut.
I prefer to cook chicken on low because there is less of a risk of overcooked, dry chicken.
I always recommend opting to cook chicken on low in the crockpot, and don’t be afraid to check on it frequently. You’ll get the hang of how long it takes your crockpot to cook chicken to perfection after just a few tries!
If your chicken is tough, it was likely overcooked. Check for doneness earlier next time!
