Dehydrating Potatoes O'Brien, or even hash browns, is quick and easy to do from frozen! No prep work, quick set up and you're ready to have shelf-stable cooked potatoes ready for breakfast or soup anytime!
Pull frozen potatoes out of the freezer. There is no need to thaw. If they are in a clump, just bang the bag on the counter once or twice.
Open the bag.
Pour onto dehydrator trays lined with mesh or parchment paper.
Place into the dehydrator at 125°C/52°C or greater.
Dehydrate for 8-15 hours until fully dry. They should sound hollow when dropped onto a hard surface and shatter when crushed.
Condition for 5-7 days. Meaning place into a jar, shake for 5 days or so to make sure potatoes aren't sticking together or getting soft (if so, throw them back into dehydrator).
Store in an airtight container for up to 4-5 years.
Rehydrate
Soak in a jar of water for 1-2 hours. Rinse, pat dry, and cook as normal.Throw into a soup and let simmer for an hour or so.
Or, throw into a soup and let simmer for an hour or so.
Notes
Once rehydrated, make sure to pat dry if you want to try a breakfast hashbrowns dish in the skillet. But for soups, you can just toss in and let rehydrate and cook while your soup simmers. I've also throw them into a casserole with other vegetables for things like Shepherd's Pie.
