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 4–5 minutes per side until a golden crust forms. The chicken does not need to be fully cooked at this stage. Remove and set aside on a plate.
03 - In the same skillet, add the minced garlic and chopped sun-dried tomatoes. Sauté for 1–2 minutes until fragrant and lightly 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, whisking gently until the sauce is smooth and evenly combined. Bring to a gentle simmer.
06 - Nestle the seared chicken breasts back into the skillet, spooning sauce over each piece to coat generously.
07 - Cover the skillet with a lid and reduce the heat to low. Simmer for 10–12 minutes until the chicken is cooked through to an internal temperature of 165°F and the sauce has thickened.
08 - Transfer the chicken to serving plates, spoon the creamy pesto sauce over each portion, and garnish with torn fresh basil leaves and additional grated Parmesan.
