Ingredients

  • 12 oz spaghetti or other pasta
  • 2 cups shredded rotisserie chicken
  • 1 teaspoon onion powder
  • 1 teaspoon garlic powder
  • 1 teaspoon salt
  • 1/2 teaspoon black pepper
  • 2 cups heavy cream
  • 4 cups shredded cheese cheddar cheese, mozzarella cheese, or a mix
  • 1 can 10 oz Rotel diced tomatoes and green chilies
  • 1 can 10.5 oz cream of chicken soup

Instructions

  • Fill a large pot with water and bring it to a boil. Add a pinch of salt to the boiling water, then add the spaghetti. Cook the spaghetti until it is al dente, about 8-10 minutes, or according to package instructions. Drain the spaghetti and then set it aside.
  • In a large bowl, combine the shredded chicken with onion powder, garlic powder, salt, and pepper. Mix them well. Add the heavy cream, Rotel, 1 ½ cups of cheese and cream of chicken soup to the bowl. Stir until all ingredients are well combined. Add the cooked spaghetti to the creamy sauce and gently toss to coat the pasta evenly.
  • Preheat your oven to 350 degrees F (175 degrees C). Transfer the spaghetti and chicken mixture into a 9x13-inch baking dish. Sprinkle 2-2 ½ cups of the remaining shredded cheese evenly over the top of the mixture.
  • Place the baking dish in the preheated oven. Bake for 15-20 minutes, or until the cheese is melted and bubbly. If you like, you can broil the casserole dish until the top is golden brown.
  • Remove the chicken casserole from the oven and let it cool for a few minutes. Serve warm and enjoy your delicious chicken tetrazzini on its own or with a side of green beans!

Notes

  • Make this recipe ahead by mixing all ingredients together in a baking dish and cover in the fridge up to 24 hours ahead of time. When ready, bake it at 350 degrees F until hot and bubbly.
  • Reheat leftovers in the microwave or in an oven at 350 degrees F until warmed.
  • Feel free to change up the cream of chicken for cream of mushroom, cream of celery, or bechamel sauce.
  • Use chopped fresh tomatoes and/or green chili in place of the can of Rotel tomatoes.
