• Sliced Baby Bella Mushrooms – They lend umami deliciousness; any mushroom variety works, or skip them if you want a simpler dish.

How to Make Chicken Tetrazzini Casserole
-
Preheat Oven: Begin by setting your oven to 350°F (175°C). Grease a 9×13-inch baking pan with a little cooking spray or butter to prevent sticking.
-
Cook Pasta: Boil the fettuccine according to the package instructions until it is al dente. Once done, drain it and cool it under running cold water to stop the cooking process.
-
Sear Chicken: In a frying pan, cook the boneless, skinless chicken breasts until they reach an internal temperature of 165°F (74°C). This ensures they are beautifully cooked and juicy—slice them thin for quicker cooling.
-
Shred Chicken: Using a stand mixer with a paddle attachment or simply chop it with a knife, shred the cooked chicken into bite-sized pieces for even mixing.
-
Combine Ingredients: In a large mixing bowl, combine the shredded chicken with the cream of chicken soup, sour cream, 1 cup of mozzarella cheese, salt, pepper, dry white wine, frozen peas, and sliced mushrooms. Mix until everything is well incorporated.
-
Add Pasta: Gently fold the cooked pasta into the chicken mixture. Be careful not to break up the pasta too much as you combine them, ensuring a hearty texture.
-
Transfer and Bake: Pour the entire mixture into the prepared baking dish. Sprinkle the remaining mozzarella and grated Parmesan cheese on top, then bake for 30-35 minutes, or until it’s bubbly and golden brown.
Optional: Garnish with fresh parsley for a pop of color before serving.
