Packed with nutrients and practical applications, onion skins can serve a variety of purposes for your health, home, and garden. Here are 15 unexpected ways to put those discarded skins to good use.

Add onion skins to your soups and broths. Not only do they enhance the flavor, but they also contribute a golden hue and extra nutrients to the mixture. - Compost Booster
