Instructions
Cut and peel onions. Slice into consistent size pieces no thicker than 1/4 inch.
Separate slices and place evenly in a single layer on mesh dehydrator tray. Some overlapping is okay.
Set dehydrator to 155°F or 68°C and dry for 7-10 hours or as needed until onions are crunchy and crumbly.
Check for dryness at 6 hours and rotate trays. Onions should be brittle and crumbly. If they're just bendable, dry them a little more.
Cool completely (let rest for 2 hours) then pour into a air tight container just large enough to hold all the dried onions (avoid large airspace). Do not crumble until ready to use.

Notes
For me, 5lbs/2.2kg sliced onions filled one 1qt/l jar.When drying onions do so outside because they release a very strong odour.Slice in uniform sized pieces for even drying.When storing dried food, larger pieces retain flavour longer, so don't crumble til ready to use.To rehydrate onions, place amount needed in bowl, cover with boiling water and let soak until soft (~30 min).1/4 cup dried onion flakes = 1 diced medium, fresh onionAfter dehydrating onions, clean dehydrator trays well and follow with another savoury vegetable to avoid cross contamination of flavours.
