Follow these easy steps to create your Creamy Pesto Chicken with Roasted Tomatoes:

1. Preheat Oven: Preheat your oven to 400°F (200°C).
2. Prepare Chicken: Season the chicken breasts with garlic powder, salt, and black pepper.
3. Sear Chicken: In a large oven-safe skillet, heat olive oil over medium heat. Add the chicken breasts and sear for about 3-4 minutes on each side until golden brown. Remove them from the skillet and set aside.
4. Roast Tomatoes: In the same skillet, add cherry tomatoes. Roast them in the oven for about 10 minutes or until they begin to blister.
5. Combine Ingredients: While the tomatoes are roasting, mix heavy cream and basil pesto in a bowl until well combined.
6. Return Chicken: After the tomatoes have roasted, return the chicken to the skillet, and pour the creamy pesto mixture evenly over the top.
7. Bake: Place the skillet back in the oven and cook for an additional 10 minutes, or until the chicken is fully cooked and reaches an internal temperature of 165°F (75°C).
8. Garnish: Remove the skillet from the oven and garnish with fresh basil leaves and grated Parmesan cheese, if desired.
9. Serve: Let the dish cool for a few moments before serving.
