Ingredients

  • 1 1/2-2 lbs Boneless/SkinlessChicken Breasts* cut into bite sized pieces
  • 1 -1 oz packet Italian Dressing Mix
  • 2 tsp Italian Seasoning
  • 3 Tbsp Olive Oil
  • 6 cloves Garlic finely minced or pressed

  • 1/2 tsp Kosher Salt
  • 1/4 tsp Pepper
  • 3 oz Cream Cheese room temperature
  • 2 cups Italian Cheese Blend mozzarella, provolone, etc., divided

Instructions

  • Add the chicken to a bowl and sprinkle on the Italian dressing, olive oil, and Italian seasoning. Mix well. Let marinate from an hour up to 24 hours.
  • Heat oven to 350 F. Lightly grease or spray a deep 9"x13" baking dish.
  • Bring a pot of salted water to boil and cook the pasta. Drain it and set it aside in the same pot you cooked it in.
  • Heat a skillet over medium high heat and add the chicken and garlic. Cook until about half done. Then add to the pasta and stir.
  • Place the skillet back on the stove and lower the heat. Melt the butter, then whisk in the flour and cook, stirring constantly, until foamy and light.
  • Whisk in the half and half. Keep stirring until the mixture thickens (bump up the heat a little if needed).
  • Whisk in the salt and pepper.
  • Stir in the cream cheese and let it melt.
  • Pour the Alfredo sauce into the pasta and chicken.
  • Add half of the Italian Cheese blend and half of the parmesan. Stir in well. Pour into the prepared baking dish and top with the remaining cheeses.
