How to Dehydrate Onions (Flakes, Minced, and Powder)
Learn how to dehydrate onions at home to make onion flakes, minced dried onions, and onion powder. This simple method helps preserve onions for long-term storage and easy cooking.
Ingredients
- 6 medium onions or as many as desired
Instructions
To Dehydrate the Onions:
- Peel the onions, trim the ends, and slice them into even pieces.
- Separate the onion layers and spread them in a single layer on dehydrator trays.
- Set the dehydrator to 125°F and dry the onions until they are completely dry and brittle, 3 to 9 hours.
- Rotate trays as needed for even drying.
- Let the onions cool completely before processing or packaging.
To Make Onion Flakes, Minced Onions, or Powder:
- Leave the dried onions as-is for flakes, or crush them into smaller pieces.
- For minced onions or onion powder, grind the dried onions using a spice grinder, coffee grinder, or blender.
- Use a fine mesh strainer over parchment paper to separate minced onions from onion powder, if desired.
To Store:
- Transfer to airtight containers, label, and store in a cool, dark place.
- Check jars after a few days for moisture. If needed, return onions to the dehydrator and dry further.
Notes
- Onions are fully dried when they are crisp and snap easily when broken.
- Store in airtight containers to prevent moisture and clumping.
- For best flavor, use within 6–12 months.
- Yield: ~1 to 1½ cups dried onions.
