What Is Onion Powder Made From? A Surprising Twist Using Onion Skins
When most people think of onion powder, they imagine it being made from the whole onion bulb. Traditionally, that’s true—onions are dried and ground into a fine powder to add flavor to a wide range of dishes.
But there’s a lesser-known and surprisingly clever alternative: using onion skins.
A New Way to Use Something You Usually Throw Away
The outer layers of onions—the thin, papery skins—are often discarded without a second thought. However, these skins actually contain a concentrated amount of flavor and nutrients.
Instead of throwing them away, you can dry and grind them into a fine powder. The result is a unique seasoning with a slightly deeper, more robust taste than traditional onion powder.
Why Use Onion Skins?
Using onion skins isn’t just creative—it’s also practical:
Reduces food waste by making use of parts that are normally thrown away
Rich in antioxidants, which are beneficial for overall health
Adds a deeper flavor to soups, sauces, and marinades
Budget-friendly, since you’re using something you already have
