01 - Pat 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 chicken breasts for 4–5 minutes per side until golden brown. Remove from the skillet and set aside; they do not need to be fully cooked at this stage.
03 - In the same skillet, add minced garlic and chopped sun-dried tomatoes. Sauté for 1–2 minutes until fragrant.
04 - Reduce heat to medium. Pour in heavy cream and chicken broth, stirring to deglaze the pan and loosen any browned bits from the bottom.
05 - Stir in basil pesto and grated Parmesan cheese 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 and simmer on low heat for 10–12 minutes, or until the chicken is cooked through (internal temperature reaches 165°F) and the sauce has thickened.
08 - Transfer to plates and garnish with torn fresh basil leaves and extra Parmesan cheese. Serve immediately.
