• 3 cloves garlic, minced
• 1 cup all-purpose flour
• 4 cups chicken broth
• 2 cups heavy cream
• 0.5 cup dry white wine (optional)
• 1 cup Parmesan cheese, grated
• 1 tsp salt
• 0.5 tsp black pepper
• 3 cups cooked turkey, shredded or cubed
• 8 oz mushrooms, sliced
• 1 cup frozen peas, thawed
• 1.5 cups shredded cheddar cheese
• 1 cup breadcrumbs
• 2 tbsp olive oil

Directions

Step 1

Preheat your oven to 375°F (190°C) and grease a 9x13-inch baking dish lightly with cooking spray or butter.

Step 2

Cook the spaghetti according to the package instructions until al dente. Drain and set aside.

Step 3

In a large saucepan, melt the butter over medium heat. Add the chopped onion and cook for 3-4 minutes until softened. Stir in the garlic and cook for an additional 1 minute.

Step 4

Sprinkle the flour over the onion mixture and stir well, cooking for 1-2 minutes to form a roux.

Step 5

Gradually whisk in the chicken broth, heavy cream, and white wine (if using), ensuring the mixture is smooth. Simmer for 3-4 minutes until the sauce thickens slightly.

Step 6

Add the Parmesan cheese, salt, and black pepper to the sauce and stir until the cheese melts. Remove from heat.

Step 7

In a large mixing bowl, combine the cooked spaghetti, shredded turkey, mushrooms, peas, and the prepared sauce. Toss until everything is evenly coated.

Step 8

Transfer the mixture into the prepared baking dish, spreading it out evenly.

Step 9

Sprinkle the shredded cheddar cheese over the top of the casserole.

Step 10

In a small bowl, mix the breadcrumbs with the olive oil until evenly coated. Sprinkle the breadcrumb mixture over the cheese layer.

Step 11

Bake the casserole in the preheated oven for 25-30 minutes or until the top is golden brown and bubbly.

Step 12

Remove the casserole from the oven and let it sit for 5-10 minutes before serving. Enjoy your Turkey Tetrazzini Casserole!
