How to freeze-dry ham

Diced lean ham freeze-dries well and adds flavor to soups and breakfast dishes. Trim the fat and expect it to taste saltier.

Eat straight from the bag?No: cook or rehydrate

Ham is cured and cooked, which makes it easy: dice and dry. It rehydrates quickly and brings a lot of flavor to bean soup, scalloped potatoes, fried rice and omelets.

It is salty, and drying concentrates salt. Use a little less ham than you would fresh, or rinse it after rehydrating.

Safety: Use fully cooked ham, or cook fresh ham to 145 °F with a 3 minute rest before drying.

Prep and loading

  1. Use cooked ham. Trim visible fat.
  2. Dice ½ inch.
  3. Spread in a single layer.

How to tell it’s done

  • Cubes are hard and dry in the center.

Not sure? The weight check compares two weighings and the expected dry weight for ham.

Problems and fixes

Greasy cubes

Fatty ham. Use lean ham or trim more.

Rehydrating and storing

Rehydrate: Hot water 10 minutes; it rehydrates fast. By weight, 100 g of dried ham takes back about 177 g of water to return to fresh weight; the rehydration calculator does any amount.

Store: Mylar with oxygen absorbers.

Ways to use it

  • Bean soup
  • Scalloped potatoes
  • Omelets and fried rice

How much fits per batch

At a normal single layer, ham load at roughly 2.4 lb of fresh food per square foot of tray. That works out to:
