Oven Method: Preheat the oven to 450 F. Place the chicken breasts or cutlets in a baking dish and drizzle with some olive oil. Bake for 16-20 minutes or until the chicken is cooked through. Length of time will depend on the thickness of the breast. Use an instant read thermometer to check the thickest part of breast; it should register 165 F. You can turn the broiler on for 3-5 minutes if you'd like the chicken a little browned. Transfer the chicken to a plate, loosely tent with aluminum foil, and let rest for 5-10 minutes before serving.
