Baked Turkey Tetrazzini

Step 1
Heat 3 tablespoons butter in a large skillet over medium heat; cook and stir mushrooms, onion, and celery until tender, 5 to 10 minutes. Sprinkle flour over mushroom mixture and stir to coat.

Step 2
Mix milk, cream cheese, Worcestershire sauce, salt, pepper, and nutmeg into mushroom mixture; cook, stirring occasionally, until cream cheese is melted and sauce is warmed, 5 to 10 minutes. Add turkey and peas to sauce.

Step 3
Preheat oven to 350 degrees F (175 degrees C). Grease a 9×13-inch baking dish.

Step 4
Bring a large pot of lightly salted water to a boil. Cook egg noodles in the boiling water, stirring occasionally until cooked through but firm to the bite, about 5 minutes. Drain and mix noodles into turkey mixture; pour into the prepared baking dish.

Step 5
Combine Parmesan cheese, bread crumbs, and 3 tablespoons melted butter together in a bowl until crumbly; sprinkle over noodle mixture.

Step 6
Bake in the preheated oven until top is browned and sauce is bubbling, about 30 minutes.
