Step‑by‑Step Instructions for Keto Creamy Pesto Chicken
Step 1: Preheat the Oven
Begin by preheating your oven to 400°F (204°C). This is crucial as it prepares the environment for your sweet cherry tomatoes, ensuring they roast beautifully as you prepare the rest of your Keto Creamy Pesto Chicken.
Step 2: Prepare Roasted Tomatoes
On a baking sheet, arrange the halved cherry tomatoes. Drizzle with one tablespoon of olive oil, and sprinkle them with sea salt and freshly ground black pepper. Roast in the oven for 15–18 minutes, until they become caramelized and tender, filling your kitchen with delightful aromas.
Step 3: Season Chicken
While the tomatoes are roasting, take your boneless skinless chicken breasts and season them generously with sea salt and pepper on both sides. This simple seasoning enhances the flavor of the chicken, which will pair beautifully with the creamy pesto sauce later on.
Step 4: Sear Chicken
In a large skillet, heat another tablespoon of olive oil over medium-high heat. Once the oil is shimmering, carefully add the seasoned chicken breasts, searing them for 3–4 minutes on each side until they turn golden brown. This step locks in the juices and adds a lovely color to your Keto Creamy Pesto Chicken.
Step 5: Create Pesto Cream Sauce
After removing the chicken from the skillet, lower the heat to medium. In the same skillet, combine the basil pesto and heavy cream, stirring gently. Let the mixture simmer for about 2–3 minutes until warmed through, then stir in the grated Parmesan cheese until melted and creamy, creating a luscious sauce to envelop your chicken.
Step 6: Finish Cooking Chicken
Return the seared chicken breasts to the skillet, making sure they’re well-coated in the pesto cream sauce. Cover the skillet and let them simmer for 8–10 minutes, or until the chicken reaches an internal temperature of 165°F (74°C). This step ensures the chicken is cooked through while absorbing all the delicious flavors.
Step 7: Plate and Serve
Once cooked, remove the skillet from heat and plate the chicken. Top each piece with the roasted tomatoes and garnish with fresh basil leaves for a pop of color. For an extra touch, sprinkle additional Parmesan cheese on top. Serve immediately and enjoy your flavorful Keto Creamy Pesto Chicken alongside your choice of low-carb sides!
