Learn how to dry green onions in the oven or dehydrator! Drying green onions is a great way to preserve them or to make green onion powder. The prep time is minimal and most of the time will be used for drying. This is an ideal project for a rainy weekend!
Prepare your baking tray by adding a piece of parchment paper.
Rinse your green onions. Remove any decaying parts.
Using your scissors, trim the onion greens into 1 cm pieces directly over your baking tray. Spread the green onion pieces evenly on the tray.
Place the tray in the oven. Crack the oven door open to reduce the temperature by placing a wooden spoon or ball of aluminum foil between the oven and the door.
Allow to dehydrate for 3-5 hours. Consider stirring every hour.
Check the dryness by crushing the pieces between your fingers. If they crumble, they are done.
Remove from oven when fully dried. Allow to cool completely before storing in an airtight container.
Notes
This recipe recommends enough green onion powder to fill a small spice jar. Once you grind down your dehydrated green onions into a powder, you'll be surprised at how little it makes!Feel free to dry however many green onions you have on hand.*A note on using a silicone tray liner.* Although we love our silicone tray liners for many reasons, the fine green onion powder will stick to the liner and can be hard to remove.
