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 the garlic is lightly softened.
04 - Reduce the heat to medium. Pour in the heavy cream and chicken broth, stirring constantly to deglaze the pan and lift any browned bits from the bottom.
05 - Stir the basil pesto and grated Parmesan cheese into the cream mixture. Continue stirring until the sauce is smooth and the cheese has fully melted. 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 and reduce the heat to low. Simmer for 10 to 12 minutes until the chicken is cooked through to an internal temperature of 165°F and the sauce has thickened.
07 - Transfer the chicken to serving plates and spoon the remaining sauce generously over each portion. Garnish with torn fresh basil leaves and additional Parmesan cheese. Serve immediately alongside pasta, mashed potatoes, or sautéed greens.
