  • Total Time: 18 hours 15 minutes
  • Yield: approximately 1/4 cup onion powder

Ingredients

Ingredients

  • 3 small yellow onions

Instructions

  1. Prepare Onions: Peel the onions thoroughly and dice them into small, even pieces to ensure uniform drying.
  2. Arrange on Dehydrator Trays: Spread the diced onions evenly across dehydrator trays, filling each tray without overlapping pieces to allow proper air circulation.
  3. Dehydrate: Set the dehydrator temperature to 125°F (52°C) and dehydrate the onions for 18-24 hours until they are completely dry and brittle.
  4. Grind into Powder: Transfer the dried onions into a food processor or use a mortar and pestle to grind them until a fine powder is formed.
  5. Store: Place the onion powder in an airtight container to maintain freshness and use it to season your favorite dishes as needed.

Notes

  • Ensure onions are fully dried to prevent mold during storage.
  • If you don’t have a dehydrator, you can dry onions in an oven at the lowest setting with the door slightly open, checking regularly.
  • Store the onion powder in a cool, dark place for up to 6 months.
  • Use gloves when handling large quantities of onions to avoid irritation.
  • Adjust the quantity according to your usage needs; the recipe scales easily.
