Season the chicken breasts with salt and pepper on both sides.
In a large skillet, heat olive oil over medium heat. Sear the chicken for 5-6 minutes on each side until golden brown. Remove from skillet and set aside.
In the same skillet, sauté the minced garlic until fragrant, about 1 minute.
Add chicken broth and heavy cream to the skillet, stirring to combine.
Mix in sun-dried tomatoes, Parmesan cheese, thyme, and oregano. Let the sauce simmer for 3-4 minutes until slightly thickened.
Return the chicken breasts to the skillet, spoon the sauce over them, and simmer for an additional 5-7 minutes until the chicken is cooked through.
Garnish with fresh basil leaves and serve immediately.
