A cucumber is about 95% water, so a pound of slices dries down to under an ounce. That makes them a poor way to stock up on cucumbers but a good way to make chips.
Plain cucumber chips are mild and airy. Season them before drying with salt, dill or ranch seasoning and they become a snack. They will not rehydrate into a crisp cucumber; the cell walls do not recover. If you want them back in food, grind them into powder for tzatziki, ranch dip or dressing.
Pickle chips are the version people ask about most. Drain the pickles, pat them dry and lay them out like cucumbers. They come out crunchy, salty and sour, and they are popular at markets next to freeze-dried candy.
Prep and loading
- Wash and slice about ¼ inch thick. Peeling is optional.
- For pickles, drain well and pat dry on towels; extra brine slows drying.
- Season fresh slices before drying if you want chips.
- Single layer. Slices shrink but do not stick much.
How to tell it’s dry
- Chips snap and feel weightless.
- Pickle slices are crisp all the way through, not leathery.
A steady weight only shows the drying has stopped; breaking the thickest piece is the check that counts. Neither is a safety test. Safety comes from tested prep, safe cooking temperatures where needed, complete drying and airtight packing. See what a kitchen scale can and cannot tell you.
Not sure? The weight check compares two weighings and the expected dry weight for cucumbers.
Problems and fixes
Soggy after rehydrating
That is expected. Use them dry, or as powder.
Pickle chips went chewy in the bag
Salt pulls moisture from the air. Bag right after the cycle ends and seal well.
Rehydrating and storing
Rehydrate: They do not come back crisp. Eat dry as chips, or powder into dips. By weight, 100 g of dried cucumbers takes back about 1840 g of water to return to fresh weight; the rehydration calculator does any amount.
Store: Mylar with an oxygen absorber. Chips crush easily, so use rigid jars or fill bags loosely.
Ways to use it
- Seasoned cucumber chips
- Pickle chips
- Powder for tzatziki and dips
How much fits per batch
At a normal single layer, cucumbers load at roughly 1.8 lb of fresh food per square foot of tray. That works out to:
| Machine | Fresh per batch | Dried per batch |
|---|---|---|
| Harvest Right Countertop 360 | 4.5 lb | 3.7 oz |
| Harvest Right Small | 5.4 lb | 4.5 oz |
| Harvest Right Medium | 8.4 lb | 7.0 oz |
| Harvest Right Large | 13.8 lb | 11.4 oz |
| Harvest Right X-Large | 28.1 lb | 1.45 lb |
