Creating Italian Chicken with Basil Pesto & Grape Tomatoes is straightforward if you follow these easy steps:

1. Preheat the oven: Set your oven to 400°F (200°C).
2. Prepare the chicken: Season the chicken breasts with salt, black pepper, and garlic powder on both sides.
3. Sear the chicken: In a large oven-safe skillet, heat olive oil over medium heat. Add the seasoned chicken breasts and cook for about 5-7 minutes on each side, until golden brown.
4. Add pesto and tomatoes: Once the chicken is browned, spread basil pesto evenly over the top of each chicken breast. Scatter the halved grape tomatoes around the chicken in the skillet.
5. Bake: Transfer the skillet to the preheated oven and bake for 15-20 minutes. The chicken should be cooked through and reach an internal temperature of 165°F (75°C).
6. Serve: Remove the skillet from the oven. If desired, sprinkle grated Parmesan cheese over the chicken and tomatoes for added flavor.
7. Garnish: Finally, garnish with fresh basil leaves before serving.
