Creating Creamy Pesto Chicken with Roasted Tomatoes is simple; just follow these steps for delicious results:

1. Preheat the Oven: Set your oven to 400°F (200°C).
2. Prepare the Tomatoes: Spread the cherry tomatoes on a baking sheet, drizzle with olive oil, and season with salt and pepper. Roast in the oven for 15-20 minutes until they are blistered and softened.
3. Season the Chicken: While the tomatoes roast, season the chicken breasts with salt and pepper on both sides.
4. Sear the Chicken: In a large skillet, heat olive oil over medium-high heat. Add the chicken breasts and cook for about 5-7 minutes on each side until golden brown and cooked through. Remove from the skillet and set aside.
5. Create the Sauce: In the same skillet, lower the heat and add minced garlic. Sauté for 1-2 minutes until fragrant. Then, add the heavy cream and pesto, stirring to combine.
6. Combine: Return the chicken to the skillet, allowing it to soak in the creamy sauce for an additional 5 minutes. Ensure the chicken is well coated.
7. Add Roasted Tomatoes: Gently stir in the roasted tomatoes, letting everything meld together for a few more minutes.
8. Garnish: Taste the sauce and adjust seasoning as needed, then remove from heat. If desired, garnish with fresh basil and grated Parmesan cheese.
9. Serve: Plate the chicken with a generous drizzle of sauce and tomatoes on top.
