01 - Pat the chicken breasts dry with paper towels. 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 on a plate.
03 - In the same skillet, add the minced garlic and chopped sun-dried tomatoes. Sauté for 1 to 2 minutes until fragrant and softened.
04 - Reduce the heat to medium. Pour in the heavy cream and chicken broth, stirring well to deglaze the pan and lift any browned bits from the bottom.
05 - Stir in the basil pesto and grated Parmesan cheese until the sauce is smooth and well combined. Bring to a gentle simmer.
06 - Return the seared chicken breasts to the skillet. Spoon sauce over each piece to coat evenly. Cover with a lid, reduce heat to low, and simmer for 10 to 12 minutes until the chicken is cooked through and the sauce has thickened.
07 - Transfer to plates and garnish with torn fresh basil leaves and additional Parmesan cheese. Serve alongside pasta, mashed potatoes, or sautéed greens.
