Season chicken breasts with salt and pepper.

In a large skillet, heat olive oil over medium-high heat. Add chicken breasts and cook until golden brown on both sides and cooked through, about 6-7 minutes per side. Remove chicken from skillet and set aside.
Add minced garlic to the skillet and saute for about 1 minute until fragrant.
Pour in chicken broth, scraping up any browned bits from the bottom of the skillet.
Bring to a simmer and cook for about 5 minutes until the liquid reduces slightly.
Stir in heavy cream, Parmesan cheese, and Italian seasoning. Simmer for another 2-3 minutes until the sauce thickens.
Return chicken breasts to the skillet and simmer for another 2-3 minutes to heat through and coat with the sauce.
Garnish with chopped parsley before serving.
