This is our step-by-step guide on how to dehydrate frozen spinach. Spinach is one of the best foods to dehydrate for long-term storage, offering a quick and convenient way to add greens to your dehydrated camping food or homemade backpacking meals. It’s pre-washed,pre-blanched, and ready to dehydrate, saving you time and effort compared to working with fresh spinach. Once dehydrated, it becomes lightweight, compact, and shelf-stable, making it a great ingredient option in our Dehydrator Chef recipes. Properly dehydrated and stored, dehydrated spinach should keep for at least 12 months in your pantry.
Empty the contents on the fruit roll sheets. Break apart the larger frozen pieces of spinach into smaller fragments.

Inspect the frozen spinach pieces for anything that shouldn't be there.
Prepare the Dehydrator
Spread the frozen spinach in a thin layer on the removable fruit roll sheet to promote even drying; one 16-ounce bag will fill two Nesco 13.5-inch round dehydrator trays.
Dehydrate the Spinach
Set the dehydrator thermostat temperature to 135 °F (57 °C). Dry for 18 to 24 hours until done.
Check on the spinach every few hours and break apart the bigger pieces into smaller fragments to help prevent case hardening.
When is the Dehydrated Spinach Done
When done, the dehydrated spinach will be crisp and brittle and will crumble into smaller pieces when crushed. There should be no wet or mushy pieces.
Equalizing and Conditioning Dehydrated Spinach
After a short cooling period, loosely pack the dehydrated spinach into a clean, dry canning jar with a tight-fitting lid, leaving some headspace.
Every day, for 7 to 10 days, check the jar for moisture. Roll the jar contents around and note any clumping or sticking. If seen, put it all back on the dehydrator for several more hours.
If you notice any mold at all, even the slightest bit, throw it all out.
Storing the Dehydrated Spinach
Use appropriate-sized canning jars for storage. Depending on how well you dehydrate the hash browns and your pantry storage conditions, it should keep for at least 12 months.
An optional food-safe desiccant packet will aid with moisture control.
Attach or include a label describing the jar contents and the date the product was dehydrated. The label identifies the canning jar contents, and the date helps with the rotation schedule. A first-in, first-out rotation helps us to use items that have been on the shelf the longest, so we're using the oldest food first.
Notes
Drying times will vary depending on your dehydrator and environmental conditions. Refer to your dehydrator owner’s manual for recommended temperatures and times for dehydrating specific foods. Remember to use drying times as a guide.
