Ingredients

• 3 cups Cooked rotisserie chicken (shredded)
• 12 ounces Uncooked spaghetti
• 4 tablespoons Butter
• 4 tablespoons All-purpose flour
• 2 cups Chicken broth
• 2 cups Milk
• 4 ounces Cream cheese (softened)
• 2 cups Shredded cheddar cheese
• 1 teaspoon Salt
• 0.5 teaspoons Black pepper
• 1 teaspoon Garlic powder
• 0.5 teaspoons Paprika
• 2 tablespoons Chopped parsley (optional, for garnish)
• 1 as needed Cooking spray

Directions

Step 1

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

Step 2

Cook the spaghetti according to package directions in a large pot of salted boiling water. Once cooked, drain and set aside.

Step 3

In a large skillet or saucepan, melt the butter over medium heat. Once melted, whisk in the all-purpose flour and cook for 1-2 minutes, stirring constantly, to form a roux.

Step 4

Gradually pour in the chicken broth while whisking to prevent lumps. Follow with the milk, continuing to whisk until the mixture is smooth and starts to thicken, about 3-4 minutes.

Step 5

Reduce the heat to low and stir in the cream cheese until it’s melted and combined. Then add 1 1/2 cups of shredded cheddar cheese, the salt, black pepper, garlic powder, and paprika. Stir until the cheese is completely melted and the sauce is smooth.

Step 6

In a large mixing bowl, combine the cooked spaghetti, shredded chicken, and the prepared cheese sauce. Toss everything together until evenly mixed.

Step 7

Transfer the mixture to the prepared baking dish, spreading it out evenly. Sprinkle the remaining 1/2 cup of shredded cheddar cheese on top.

Step 8

Bake in the preheated oven for 20-25 minutes, or until the cheese on top is bubbly and golden brown.

Step 9

Remove from the oven and let the casserole cool for 5 minutes. Garnish with chopped parsley if desired.

Step 10

Serve warm and enjoy your comforting Rotisserie Chicken Spaghetti Casserole!
