Creating the perfect Creamy Pesto Chicken with Roasted Tomatoes is a simple process if you follow these steps carefully:

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 black pepper. Spread them evenly on a baking sheet.
3. Roast Tomatoes: Place the tomatoes in the oven and roast for about 15 minutes or until they are blistered and tender.
4. Prepare Chicken: While the tomatoes are roasting, season the chicken breasts with salt, black pepper, and Italian seasoning.
5. Sear Chicken: In a large skillet over medium-high heat, add a tablespoon of olive oil. Sear the chicken breasts for about 5-6 minutes on each side until they are golden brown and cooked through.
6. Add Garlic: Once the chicken is cooked, add minced garlic to the skillet and sauté for an additional 1-2 minutes until fragrant.
7. Create Sauce: Lower the heat, add heavy cream and pesto to the skillet. Stir well to combine all ingredients and let simmer for about 2-3 minutes until the sauce thickens slightly.
8. Combine Ingredients: Gently add the roasted tomatoes to the creamy pesto mixture and stir to coat them in the sauce.
9. Serve: Remove from heat and plate your creamy chicken.
10. Garnish: Top with grated Parmesan cheese and fresh basil, if desired, before serving.

By following these steps, you’ll ensure that your dish turns out not just incredible but also beautifully presented.
