Season the chicken breasts evenly on both sides with salt, black pepper, garlic powder, and paprika.
Heat olive oil and butter in a large skillet over medium heat until hot.
Add the chicken breasts and sear for four to five minutes per side until golden brown, then remove and set aside.
Add the minced garlic to the same skillet and cook briefly until fragrant.
Pour in the chicken broth and scrape the bottom of the pan to release any browned bits.
Stir in the heavy cream, Parmesan cheese, Italian seasoning, and red pepper flakes if using.
Simmer the sauce for three to four minutes until it begins to thicken.
Return the chicken breasts to the skillet and spoon the sauce over them.
Simmer for eight to ten minutes until the chicken is fully cooked and the sauce is creamy.
Remove from heat and garnish with fresh parsley before serving.
