Ingredients:
- 4 tbsp unsalted butter
- 1/4 cup all-purpose flour
- 2 cups whole milk
- 1 cup low-sodium chicken broth
- 1 tsp garlic powder
- 1/2 tsp salt
- 1/4 tsp black pepper
- 3 cups cooked chicken, shredded
- 8 oz mushrooms, sliced
- 12 oz spaghetti
- 1 cup shredded mozzarella cheese
- 1/2 cup grated Parmesan cheese
- 2 tbsp fresh parsley, chopped
- 1/2 cup Panko breadcrumbs
- 2 tbsp melted butter
- 2 tbsp grated Parmesan cheese
Instructions:
- Bring a large pot of salted water to a boil. Cook pasta for 2 minutes less than the package instructions for al dente.
- In a large skillet over medium heat, melt 4 tbsp of butter. Whisk in the flour and cook for 1-2 minutes.
- Slowly pour in the milk and chicken broth, whisking constantly. Simmer until the sauce thickens enough to coat the back of a spoon.
- Stir in the garlic powder, salt, and pepper.
- Fold the shredded chicken, sliced mushrooms, and half of the mozzarella and Parmesan into the sauce.
- Stir in the under-cooked pasta and parsley until coated, then pour the mixture into a 9x13-inch baking dish.
- Mix Panko, melted butter, and the remaining Parmesan in a small bowl and sprinkle evenly over the top.
- Bake at 375°F (190°C) for 20-25 minutes until the edges are bubbling and the top is deep gold.
