Ingredients

• 3 cups turkey (cooked and shredded)
• 12 ounces spaghetti
• 4 tablespoons unsalted butter
• 0.25 cup all-purpose flour
• 2 cups chicken broth
• 1 cup whole milk
• 0.5 cup heavy cream
• 1 cup Parmesan cheese (grated)
• 1 cup mozzarella cheese (shredded)
• 2 cloves garlic (minced)
• 4 cups baby spinach (fresh)
• 1 medium onion (finely chopped)
• 0.25 cup dry white wine (optional)
• 2 tablespoons olive oil
• 1 teaspoon salt
• 0.5 teaspoon ground black pepper
• 1 cup panko breadcrumbs
• 2 tablespoons fresh parsley (chopped, for garnish)

Directions

Step 1

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

Step 2

Cook the spaghetti in a large pot of salted boiling water until al dente. Drain and set aside.

Step 3

Heat the olive oil in a large skillet over medium heat. Sauté the onion and garlic until the onion is translucent, about 3-4 minutes.

Step 4

Add the baby spinach to the skillet and cook until wilted, about 2 minutes. Remove from heat and set aside.

Step 5

In a medium saucepan, melt the butter over medium heat. Whisk in the flour and cook for 1-2 minutes to remove the raw flour taste.

Step 6

Gradually add the chicken broth, whisking constantly to prevent lumps. Stir in the milk, heavy cream, and white wine (if using). Continue to cook, stirring, until the sauce thickens, about 5-7 minutes.

Step 7

Stir in 3/4 cup of Parmesan cheese, salt, and black pepper into the sauce. Remove from heat.

Step 8

In a large mixing bowl, combine the cooked spaghetti, shredded turkey, sautéed spinach mixture, and the sauce. Mix until evenly coated.

Step 9

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

Step 10

Top with the remaining Parmesan cheese, mozzarella cheese, and panko breadcrumbs evenly.

Step 11

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

Step 12

Remove from the oven and let the casserole rest for 5 minutes before serving.

Step 13

Garnish with chopped fresh parsley and serve warm. Enjoy!
