Ingredients

  • 4 quarts water
  • 1 tablespoon kosher salt (for seasoning pasta)
  • 1 pound spaghetti
  • 2 tablespoons olive oil
  • ½ cup finely chopped yellow onion
  • 1 tablespoon minced garlic
  • 1 teaspoon Italian seasoning
  • 2 cups marinara sauce (store-bought or homemade)
  • ½ cup heavy cream
  • 2 cups cooked shredded chicken
  • 1 ½ cups shredded mozzarella cheese
  • ½ cup shredded parmesan cheese
  • 1 tablespoon chopped parsley

Directions

  1. Set the oven rack to the middle position and preheat the oven to 375 degrees Fahrenheit.
  2. In a large pot, bring 4 quarts of water to a boil. Add 1 tablespoon of kosher salt and stir to dissolve.
  3. Add in 1 pound of spaghetti and cook according to package directions until al dente, about 10 minutes. Drain the noodles in a colander and rinse with cool water for about 30 seconds to stop the cooking.
  4. Heat 2 tablespoons of olive oil in a large skillet or Dutch oven over medium-low heat. Add ½ cup of finely chopped yellow onion, 1 tablespoon of minced garlic, and 1 teaspoon of Italian seasoning. Sauté until the onions are translucent, about 3 minutes.
  5. Add in 2 cups of marinara sauce and stir to combine. Cook until the sauce is hot, about 2 to 3 minutes. Turn off the heat and stir in ½ cup of heavy cream. Season the sauce with more salt and pepper to taste.
  6. Add the drained spaghetti to the sauce and stir to combine. Mix in 2 cups of cooked shredded chicken.
  7. Transfer the pasta to a 9 x 13-inch baking dish.
  8. Sprinkle the pasta with 1 ½ cups of shredded mozzarella cheese and ½ cup of shredded parmesan cheese.
  9. Cover with foil and bake until the cheese melts and the pasta is hot, about 15 to 20 minutes. For a more browned surface, remove the foil and broil the casserole until lightly browned, about 2 to 5 minutes.
  10. Garnish with 1 tablespoon of chopped parsley and serve immediately.
