Preparing Creamy Pesto Chicken with Roasted Tomatoes can be done seamlessly if you follow these simple steps:

1. Preheat Oven: Begin by preheating your oven to 400°F (200°C).
2. Prepare Tomatoes: In a mixing bowl, toss the halved cherry tomatoes with olive oil, salt, and pepper. Spread them on a baking sheet.
3. Roast Tomatoes: Place the baking sheet with tomatoes in the oven and roast for about 15-20 minutes, or until they are soft and caramelized.
4. Cook Chicken: While the tomatoes are roasting, season the chicken breasts with salt and pepper. In a large skillet over medium heat, cook the chicken for about 6-7 minutes per side, or until golden brown and cooked through.
5. Make the Sauce: In the same skillet, reduce the heat to low. Add the heavy cream and pesto to the pan, stirring until well combined. Allow the sauce to simmer for a few minutes to thicken.
6. Combine Ingredients: Once the chicken is cooked, return it to the skillet with the creamy pesto sauce, ensuring each piece is well coated.
7. Add Roasted Tomatoes: Carefully fold the roasted tomatoes into the sauce, mixing gently to combine flavors.
8. Finish with Cheese: Sprinkle grated Parmesan cheese over the chicken and let it melt slightly before serving.
9. Garnish: Remove from heat and garnish with fresh basil leaves if desired.

These clear steps will guide you in creating this delightful dish with ease, ensuring a satisfying meal for you and your loved ones.
