Creamy Chicken Tetrazzini starts with sautéed mushrooms, onions, freshly cooked chicken breasts, and al dente linguine; and ends up a delicious baked pasta dish with a crunchy cheesy bread crumb topping. You are going to love it!
Heat a large skillet over medium-high heat. Season chicken breasts with salt and pepper. Add 1 TB olive oil to pan and cook chicken, 5 to 7 minutes per side, until cooked through to an internal temperature of 165 degrees Fahrenheit. Remove chicken from pan, dice, and set aside.
Preheat oven to 350 degrees Fahrenheit and lightly grease a 9x13 pan.
Cook linguine for 2 minutes less than the package directions as the pasta will continue to soften in the oven.
Meanwhile, add 2 TB olive oil to a large pot over medium high heat. Add in onion and mushrooms cook until softened, about 5 to 7 minutes, stirring frequently.
Add butter in with mushrooms and onions and let melt. Stir in flour until combined. Add in garlic and cook 1 to 2 minutes more.
Pour in milk and chicken broth and bring to a simmer over medium-high heat. Just as it reaches a simmer the mixture should thicken. Stir in frozen peas and diced chicken, then immediately reduce the heat to low and stir in cream cheese until melted. Taste and season with salt and pepper as desired.
Stir cooked pasta in with the sauce until combined then transfer it all to the prepared 9x13 pan. In a small bowl, use a fork to toss together panko bread crumbs, parmesan cheese, and 3 tsp olive oil until combined. Sprinkle evenly on top of the pasta in the pan.
Bake in the preheated 350 degree oven for 25-30 minutes until the crumbs on top are golden brown. Serve hot.

Notes
Short on time? Instead of cooking the chicken breasts separately, you can use 2 cups of pre-cooked diced chicken or shredded rotisserie chicken.
