How to freeze-dry ground beef

Cooked, well-drained ground beef is a pantry staple for chili, tacos and pasta. Fat is the enemy of storage, so use lean beef and get the grease out.

Eat straight from the bag?No: cook or rehydrate

Browned ground beef is one of the most practical things to keep on the shelf. It rehydrates in about 10 minutes and goes straight into tacos, spaghetti sauce, chili and casseroles.

The difference between beef that keeps and beef that goes rancid is fat. Lean beef (90% or leaner) cooked, drained, and blotted dries well. Some owners also rinse the cooked crumbles with hot water to remove more fat, which works but takes some flavor with it.

Safety: Cook ground beef to 160 °F before drying, as USU Extension advises. Freeze-drying does not kill bacteria.

Prep and loading

  1. Brown the beef in small crumbles until it reaches 160 °F with no pink.
  2. Drain in a colander. Rinse with hot water if you want the leanest result, then drain again.
  3. Blot on paper towels until no grease shows.
  4. Spread ½ inch deep. Break up clumps; clumps hold fat and moisture.
  5. Season after rehydrating, not before; salt and spices taste stronger when dried.

How to tell it’s done

  • Crumbles are hard and dry, with no soft or greasy centers.
  • A paper towel pressed on the tray picks up little or no grease.

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

Problems and fixes

Greasy bag or rancid smell later

Too much fat left on the meat. Use leaner beef, drain and blot more, and rotate within a year.

Chewy after rehydrating

Use hot liquid and give it the full 10 minutes, or simmer it in sauce.

Rehydrating and storing

Rehydrate: Cover with hot water or broth 10 minutes. By weight, 100 g of dried ground beef takes back about 131 g of water to return to fresh weight; the rehydration calculator does any amount.

Store: Mylar with oxygen absorbers. Leaner beef keeps longer.

Ways to use it

  • Tacos and burritos
  • Spaghetti sauce
  • Chili
  • Shepherd’s pie

How much fits per batch

At a normal single layer, ground beef load at roughly 2.2 lb of fresh food per square foot of tray. That works out to:
