Boneless chicken breasts are a staple for any time-pressed cook's kitchen because they're quicker to cook than bone-in chicken breasts.
Chicken breasts are susceptible to drying out, so they're best cooked quickly using high heat. That means skillet-cooking, stir-frying, roasting, or grilling chicken breasts are the best routes. Skillet-cooking is particularly easy because you can make a sauce in the same pan.
When it comes to cooking boneless chicken breasts, the terms "saute," "pan-fry," and "skillet-cook" all refer to the same basic preparation: Cooking chicken breasts in a skillet in a small amount of fat (such as cooking oil, olive oil, or butter) or in a skillet sprayed with nonstick cooking spray.
Boiling, or poaching, chicken breasts is perfect when chicken is part of a larger recipe.
