Ingredients
  

Chicken

  • 2 chicken breasts
  • 1 teaspoon salt
  • 1 teaspoon garlic powder
  • ½ teaspoon pepper
  • 1 teaspoon dried oregano
  • 3 tablespoons olive oil

Pasta

  • 3 cups penne pasta cooked to al dente

Alfredo Sauce

  • 1 tablespoon olive oil
  • 3 tablespoons butter
  • 5 cloves garlic minced
  • ¼ cup flour
  • 1 ½ cups chicken stock
  • 2 cups milk
  • 1 cup heavy cream
  • 1 ¼ cups shredded parmesan plus more for topping (optional)
  • ¼ cup grated parmesan
  • ¾ teaspoon salt
  • pepper as needed
  • 1 teaspoon fresh or dried parsley chopped
  • 1 ½ cups mozzarella shredded
I always use Kosher salt in my kitchen! If using table salt, start with half the amount and adjust to taste, as it is much "saltier" by volume.

Instructions
 

  • Season the chicken with the salt, pepper, garlic powder and dried oregano. Heat a large skillet over medium heat and add in the olive oil. Pan sear the chicken until the internal temperature reaches 165° F. Remove from the pan and set aside. Cut (or shred) the chicken into bite sized pieces.
  • While the chicken is cooking start the sauce. In a medium saucepan over medium heat, add the olive oil and butter. Add the minced garlic to the pan and cook for thirty seconds. Add in the flour and make the roux.
  • Next, slowly pour in the chicken stock, whisking to prevent the roux from clumping up. Once the chicken stock has been fully incorporated add in the milk and heavy cream.
  • Bring to a simmer, stirring regularly to prevent sticking, then add all of the parmesan cheese, parsley, salt and pepper. Stirring until the liquid reaches sauce consistency. Remove from the heat. Preheat the oven to 350°F.
  • Add the cooked pasta and chicken to a 9x13 baking dish. Pour over the sauce and mix well to combine.
  • Top with mozzarella cheese and a little parmesan cheese. Cover with foil and bake for 20 minutes.
  • Remove the foil and bake for an additional 5 minutes or until the cheese is melted and bubbly. Garnish with parsley is desired. Enjoy!
