PREP: Position a rack in the center of the oven and preheat the oven to 375ºF. Spray a nonstick 13x9 baking dish with cooking spray; set aside.
SAUTE: Heat the butter in a large saucepan and saute the mushrooms over medium-high heat until they brown; about 7-9 minutes. Then, stir in the alfredo sauce, chicken stock, and ricotta cheese. Season with garlic powder, basil, and red pepper flakes. When the sauce is smooth and heated through, stir in the peas and turkey (or chicken.) Then, fold in the prepared egg noodles and stir to combine.
BAKE: Add the prepared turkey pasta mixture to the baking dish and sprinkle with cheese. Bake the turkey pasta bake for 15-18 minutes or until the cheese is bubbly and golden brown on top. You could also give it a minute under the broiler at the end to help it along. Sprinkle with freshly chopped parsley on top if desired and serve!
