01 - Pat the chicken breasts dry and season both sides evenly with salt, black pepper, and garlic powder.
02 - Heat olive oil in a large skillet over medium-high heat. Sear the chicken breasts for 4 to 5 minutes per side until a golden crust forms. The chicken does not need to be fully cooked at this stage. Remove from the skillet and set aside.
03 - In the same skillet, add the minced garlic and chopped sun-dried tomatoes. Sauté for 1 to 2 minutes until fragrant and slightly softened.
04 - Reduce the heat to medium. Pour in the heavy cream and chicken broth, stirring to deglaze the pan and lift any browned bits from the bottom.
05 - Stir in the basil pesto and grated Parmesan cheese, mixing until the sauce is smooth and well combined. Bring to a gentle simmer.
06 - Place the seared chicken breasts back into the skillet, spooning sauce over each piece to coat evenly.
07 - Cover the skillet with a lid and simmer on low heat for 10 to 12 minutes, or until the chicken is cooked through to an internal temperature of 165°F and the sauce has thickened.
08 - Transfer to plates and garnish with torn fresh basil leaves and additional Parmesan cheese. Serve immediately.
