Follow these simple steps to create the delicious Creamy Pesto Chicken with Roasted Tomatoes:

1. Preheat the Oven: Preheat your oven to 400°F (200°C).
2. Prepare Chicken: Season the chicken breasts with salt and pepper.
3. Sear the Chicken: In a large skillet, heat 1 tablespoon of olive oil over medium-high heat. Add the chicken breasts and cook for about 4–5 minutes on each side until golden brown. Remove from the pan and set aside.
4. Roast the Tomatoes: In the same skillet, add the cherry tomatoes and the remaining olive oil. Roast them for 6–8 minutes until they start to blister.
5. Make the Sauce: Lower the heat and add the heavy cream to the skillet with the tomatoes. Stir in the basil pesto and let the sauce simmer for about 5 minutes, allowing it to thicken.
6. Combine Chicken and Sauce: Return the chicken breasts to the skillet. Spoon the sauce over the chicken, then cover and cook for an additional 8–10 minutes, until the chicken reaches an internal temperature of 165°F (74°C).
7. Garnish and Serve: Once cooked, sprinkle the dish with freshly grated Parmesan cheese and garnish with additional basil leaves.
