In healthy cooking, the choice of cooking method is as important a consideration as the ingredients used in the dish. Fortunately, with the exceptions of deep-frying and pan-frying, most familiar cooking techniques are well suited to a menu built around healthy cooking goals. Some of these techniques need a few minor adaptations, while others work as is.
The following cooking methods such as sauteing, stir-frying, grilling, broiling, roasting and baking, smoke-roasting, steaming, shallow-poaching, deep-poaching, stewing and braising, and microwave cooking can be used with great success in healthy cooking. Each technique increases the quality and flavor of the finished dish in several ways. When ingredients and preparation are handled properly, great-tasting, healthy foods are sure to follow.
