Course: Pantry Staple

  • onions
  • mandoline slicer or sharp knife and cutting board
  • dehydrator
  • tray liners for the dehydrator trays or parchment paper cut to fit


  • Peel the onions and cut off any bad spots.
  • Set up your mandoline with the julienne blade or use the blade that will give you the thinnest slices. Or use a knife and cutting board and cut the thinnest slices you can.
  • Cut the slices (or julienne pieces) into a fine mince.
  • Put the liners or parchment paper on your dehydrator trays.
  • Spread the onions out as evenly as you can on the trays.
  • Put the trays in the dehydrator and set the temperature to 145°F.
  • After 2 hours, turn it down to 125°F. Break up any large clumps of onions at this time. Drying time will depend on the size of your onion pieces, how much moisture is in them, and the humidity level.
  • When the pieces are completely dry, let them cool before you put them in a storage container.

How to rehydrate dried minced onions

  • I use the boiling water method to rehydrate most of the things I use. The basic formula is 1 cup boiling water (or other liquid) to 1 cup dried food.


One onion makes about 1/4 cup of dried minced onions. So, if your recipe calls for a whole onion, you would take 1/4 cup of minced onions and add 1/4 cup of boiling water and soak for 5 to 20 minutes. Just leave it in the water until it's absorbed all or most of the liquid. Then use just like you normally would.
