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 to the skillet and cook for about 6-8 minutes per side, or until golden brown and cooked through. Remove the chicken from the skillet and set it aside on a plate.
In the same skillet, add the minced garlic and chopped sun-dried tomatoes. Cook for about 2 minutes, stirring occasionally, until the garlic becomes fragrant and the tomatoes soften.
Pour in the chicken broth and bring it to a simmer. Let it cook for about 5 minutes, allowing the flavors to meld together.
Reduce the heat to low and stir in the heavy cream, dried basil, dried oregano, and red pepper flakes (if using). Cook for an additional 2-3 minutes, stirring occasionally, until the sauce thickens slightly.
Return the chicken breasts to the skillet, nestling them into the sauce. Cook for another 2-3 minutes to warm the chicken through and allow it to absorb some of the sauce.
Serve the chicken with creamy sun-dried tomato sauce hot with your choice of sides, such as rice, pasta, or roasted vegetables.
