How to Turn Onion Scraps into Onion Seasoning 

Create your own onion seasoning powder at home with leftover onion scraps! Daniel Hewes East Hampton Green Eating Expert shares a sustainable, zero waste food recipe for Onion Peel Powder: 

Before you toss out your onion scraps, consider saving the peel and less edible pieces!  The truth is, the entire onion is edible… even the not-so-pretty scraps that are leftover!  When Daniel Hewes prepares a meal with onions, he always makes sure to save the peel and other scraps.  As a Green Eating Expert, Hewes is conscious of eliminating food waste and sustainability in the kitchen.  One of his favorite ways to make use of onion scraps is by making Onion Peel Powder.  Here’s how to recreate the recipe at home to make homemade onion powder:

Step 1: Arrange onion skins and scraps on a baking sheet and place in the oven at 150 degrees F for 3 hours.  Alternatively, Daniel Hewes East Hampton Nutritionist and Green Eating Expert utilizes a dehydrator.  But if you don’t have such a kitchen appliance at your disposal, this method will work just fine! 

Step 2: Once you notice that the skins have completely dried out, crush up the skins in a food processor, blender, with a mortar and pestle or by hand. 

Step 3: Enjoy!  Store in an airtight container and keep out of direct sunlight and enjoy use in the kitchen for up to 6 months.
