In a large 12 inch skillet stir together chicken, olive oil, and all chicken seasoning spices over medium-high heat. Toss chicken so it’s evenly coated in spices. Cook until chicken pieces are thoroughly cooked, with an internal temperature of 165F. Set cooked chicken pieces aside in a separate bowl.
In the same skillet, cook onion and minced garlic over medium-high heat under onions are tender.
Add cream cheese and butter to the skillet. Cook just until melted.
Add chicken broth, heavy cream, parsley, garlic powder, and dried oregano. Cook over medium-high until boiling. Stir in 1/2 cup of Parmesan. Add the box of pasta and bring it back to a slow simmer. Simmer about 8 minutes or until pasta is done, stirring occasionally.
Add chicken back to the skillet, make sure to use a spatula to get all those spices from the chicken bowl back into the skillet, and stir to mix well. Simmer over low heat for 5 minutes stirring often to reheat the chicken.
Before serving, sprinkle the remaining 1/4 cup Parmesan cheese and minced basil over top.
Serve hot.
