Season the chicken breasts with salt and pepper on both sides.
In a large skillet, heat the olive oil over medium-high heat. Add the chicken breasts and cook for about 6-7 minutes on each side, or until golden brown and cooked through. Remove the chicken from the skillet and set aside.
In the same skillet, add the minced garlic and sauté for about 1 minute until fragrant.
Pour in the chicken broth and bring to a simmer, scraping up any brown bits from the bottom of the skillet.
Reduce the heat to low and stir in the heavy cream, thyme, oregano, and Parmesan cheese. Mix well and let it simmer for about 3-4 minutes until the sauce thickens slightly.
Return the chicken to the skillet, coating it in the creamy sauce. Let it cook for an additional 2-3 minutes to heat through.
Garnish with chopped parsley before serving.
