Ingredients

• 12 ounces spaghetti
• 6 tablespoons unsalted butter
• 1 cup all-purpose flour
• 4 cups chicken broth
• 2 cups whole milk
• 1 cup heavy cream
• 2 teaspoons salt
• 1 teaspoon ground black pepper
• 0.25 teaspoons nutmeg (optional)
• 3 cups cooked chicken breast, shredded or cubed
• 8 ounces mushrooms, sliced
• 1.5 cups Parmesan cheese, grated
• 1 cup sharp cheddar cheese, shredded
• 1 cup breadcrumbs
• 1 tablespoon olive oil
• 2 tablespoons fresh parsley, chopped (optional, for garnish)

Directions

Step 1

Preheat your oven to 375°F (190°C). Grease a 9x13-inch baking dish with nonstick spray or butter and set aside.

Step 2

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

Step 3

In a large skillet or saucepan over medium heat, melt 4 tablespoons of butter. Add the flour and whisk constantly for 1-2 minutes to make a roux.

Step 4

Gradually pour in the chicken broth, whisking constantly to avoid lumps. Add the milk and heavy cream, continuing to whisk until the mixture is smooth and begins to thicken, about 5 minutes.

Step 5

Stir in the salt, black pepper, and nutmeg (if using). Reduce the heat to low and simmer for another minute.

Step 6

Add the shredded chicken and mushrooms to the sauce, stirring until evenly coated. Remove from heat.

Step 7

In a large mixing bowl, combine the cooked spaghetti, the sauce mixture, 1 cup of Parmesan cheese, and the cheddar cheese. Toss until well combined.

Step 8

Transfer the mixture to the prepared baking dish and spread it out evenly.

Step 9

In a small bowl, mix the breadcrumbs with the remaining 2 tablespoons of melted butter and 0.5 cup of Parmesan cheese. Stir in the olive oil until the breadcrumbs are coated and crumbly.

Step 10

Sprinkle the breadcrumb mixture evenly over the pasta in the baking dish.

Step 11

Bake in the preheated oven for 25-30 minutes, or until the top is golden brown and the casserole is bubbling at the edges.

Step 12

Remove the tetrazzini from the oven and let it rest for 5 minutes before serving. Garnish with chopped parsley, if desired, and serve warm.
