Ingredients
  

  • 8 oz spaghetti
  • 2 tbsp butter
  • ½ cup finely chopped yellow onion
  • 2 cups shredded cooked chicken
  • 1 can (10.5 oz) cream of chicken soup
  • 1 cup sour cream
  • ½ cup chicken broth
  • ½ cup grated Parmesan cheese
  • 1 tsp garlic powder
  • ½ tsp onion powder
  • ½ tsp salt
  • ¼ tsp black pepper
  • 2 cups shredded mozzarella cheese

Method
 

  1. Cook spaghetti in salted boiling water until al dente, about 8 minutes. Drain well. Meanwhile, melt butter in a skillet over medium heat and sauté onion for about 5 minutes until soft.
  2. Remove skillet from heat, add soup, sour cream, broth, Parmesan, garlic powder, onion powder, salt, and pepper. Whisk smooth, then warm over low heat for 2 minutes. Stir in chicken.
  3. Toss drained spaghetti into the sauce until evenly coated. Transfer to a greased 9x13 inch baking dish and spread evenly. Top with mozzarella.
  4. Bake at 375°F (190°C) for 20 minutes, then broil 2 to 3 minutes until golden and bubbly. Let rest 5 minutes, then scoop into bowls and serve.

Notes

Rotisserie chicken shaves about 10 minutes off the prep time. You can assemble the casserole a few hours ahead and keep it covered in the refrigerator until ready to bake; add 5 to 10 minutes to the bake time if starting cold.
