Instructions

Preheat oven to 350°F (175°C). Lightly grease a 9×13-inch baking dish.
Cook pasta according to package directions. Drain and set aside.
In a large skillet, melt butter over medium heat. Add onion and cook for 3 minutes until softened.
Add garlic and mushrooms; cook 5–6 minutes until mushrooms are tender and moisture has evaporated.
Sprinkle flour over the mixture and stir to coat. Cook for 1–2 minutes to eliminate raw flour taste.
Gradually whisk in broth. Bring to a simmer and cook 3–4 minutes until thickened.
Stir in cream (and sour cream, if using) and Parmesan. Season with salt and pepper to taste.
In a large bowl, combine cooked pasta, turkey, sauce, and half of the mozzarella or Swiss cheese.
Transfer mixture to the prepared baking dish. Top with remaining cheese.
Bake uncovered for 25–30 minutes or until bubbly and golden on top.
Garnish with parsley before serving, if desired.

Notes

Use rotisserie chicken instead of turkey for convenience.Add vegetables like peas, spinach, or broccoli for extra nutrition.Top with buttery breadcrumbs or crushed crackers for a crunchy finish.Swap in cream of mushroom soup for a shortcut version of the sauce.Can be assembled ahead and refrigerated or frozen before baking.
