How to freeze-dry chili

A big pot of chili is the classic freeze-dryer meal. Use lean meat, skim the fat, spread it thin, and you have just-add-water dinners.

Chili is the meal owners make again and again: one pot, several trays, and a shelf of complete dinners that need only hot water. Beans, tomatoes, peppers and lean meat all dry well together.

Write the fresh weight of each portion on the bag before drying. Rehydrating back to that weight gives the right thickness every time.

Safety: Cook and cool chili quickly; dry it within a few days of cooking.

Prep and loading

  1. Cook chili with lean ground beef or turkey. Skim any fat on top.
  2. Cool it in the fridge, then skim again; fat sets on top when cold.
  3. Spread ½ inch deep on lined trays. Weigh each tray’s portion first if you want portioned bags.
  4. Pre-freeze.
  5. Break the dried sheet into chunks before bagging.

How to tell it’s done

  • Chunks are dry and crumbly through; meat pieces are hard.

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

Problems and fixes

Greasy patches

Fat in the chili. Chill and skim before drying.

Too thin after rehydrating

Added too much water. Rehydrate by weight using the number on the bag.

Rehydrating and storing

Rehydrate: Boiling water to the original weight, stir, rest 10 minutes. By weight, 100 g of dried chili takes back about 322 g of water to return to fresh weight; the rehydration calculator does any amount.

Store: Mylar with oxygen absorbers, one meal per bag.

Ways to use it

  • Dinner with hot water
  • Chili dogs and nachos
  • Backpacking

How much fits per batch

At a normal single layer, chili load at roughly 2.6 lb of fresh food per square foot of tray. That works out to:

MachineFresh per batchDried per batch

Harvest Right Small7.8 lb1.86 lb
Harvest Right Medium12.2 lb2.89 lb
