When searing the chicken breasts, make sure the skillet is hot enough before adding the olive oil. This ensures a nice golden brown crust, which locks in the juices and enhances the flavor. Additionally, when cooking the vegetables for the ragout, avoid overcrowding the skillet to ensure even cooking and to prevent steaming instead of sautéing.
