Begin by seasoning the chicken breasts with salt and pepper on both sides.
In a large skillet, heat the olive oil over medium-high heat. Once hot, add the chicken breasts and cook for about 6-7 minutes on each side, or until the chicken is golden brown and no longer pink in the center. Remove from the skillet and set aside.
In the same skillet, lower the heat to medium and add the minced garlic. Sauté for 1-2 minutes until fragrant, being careful not to burn it.
Pour in the chicken broth, scraping any browned bits from the bottom of the skillet. Bring to a simmer.
Stir in the heavy cream, dried thyme, and dried oregano. Allow the sauce to cook for about 2-3 minutes, or until it thickens slightly.
Add the grated Parmesan cheese to the sauce, stirring until melted and combined.
Return the cooked chicken to the skillet, coating it in the creamy sauce. Let it simmer for an additional 5 minutes to heat through.
Garnish with fresh parsley if desired, and serve hot.
