Start by cutting chicken breasts into 1 inch pieces. Season with 1/2 a teaspoon of kosher salt and a few turns of pepper.
Brown chicken in 2 tablespoons of olive oil over medium high heat, depending on how big your pan is you may need to brown in two batches to prevent over crowding.
It does not need to be cooked through at this point, it will continue cooking as it simmers.
Once chicken is browned, add two more tablespoons of olive oil and minced garlic and saute for about one minute.
Add chicken broth, heavy cream, 1 teaspoon kosher salt, and 1/2 teaspoon freshly ground black pepper, and uncooked pasta to pan and stir.
Once mixture starts to bubble, cover and reduce to a simmer.
Simmer for 15-20 minutes or until pasta is tender.
Remove from heat and stir in shredded parmesan cheese.
Season with additional salt and pepper as needed and sprinkle with fresh parsley.
