Preheat your oven to 375°F (190°C). Grease a 9x13-inch baking dish and set aside.
Cook the spaghetti according to the package instructions until al dente. Drain and set aside.
In a large skillet, melt the butter over medium heat. Add the chopped onion and cook for 2-3 minutes until softened.
Add the sliced mushrooms to the skillet and sauté for 5-7 minutes until tender and browned.
Sprinkle the flour over the mushrooms and onions, stirring constantly for 1-2 minutes to create a roux.
Slowly pour in the chicken broth, whisking to combine, and let simmer until the mixture thickens, about 3-4 minutes.
Stir in the heavy cream and grated Parmesan cheese until the sauce is smooth and creamy.
Add the cooked turkey, thawed peas, salt, and black pepper to the sauce, stirring to combine.
In a large bowl, combine the cooked spaghetti with the sauce mixture, tossing to coat the pasta evenly.
Transfer the mixture to the prepared baking dish, spreading it out evenly.
In a small bowl, mix the breadcrumbs with the olive oil, then stir in the shredded mozzarella cheese.
Sprinkle the breadcrumb and cheese mixture over the top of the casserole.
Bake in the preheated oven for 20-25 minutes, or until bubbly and the top is golden brown.
Let the Turkey Tetrazzini cool for 5 minutes before serving. Enjoy!
