Freeze Dry Math

Can you freeze-dry bacon?

Cooked bacon is mostly fat and only about 12% water. Freeze-drying barely changes it and the fat goes rancid. Fine for a short trip, not for the pantry.

Bacon looks like a great candidate until you look at what it is made of. Pan-fried bacon is about 12% water and around 40% fat, so there is almost nothing for a freeze dryer to remove. The fat stays, and fat at room temperature goes rancid.

Owners who dry bacon bits for camping trips report they keep a few weeks to a couple of months. That is useful, but it is not what most people buy a freeze dryer for.

USDA’s own storage chart for bacon makes the point. Bacon you cook yourself keeps 4 to 5 days in the fridge and about a month in the freezer. Store-bought bacon bits made with real bacon are good until the date on the jar unopened and up to 6 weeks in the fridge once opened. Canned bacon is the long-keeping option, at 2 to 5 years in the pantry. A home freeze dryer cannot turn bacon into anything like canned bacon, because it takes out water and leaves the fat behind.

Lean cured pork is a different story. Canadian bacon and lean ham have far less fat and freeze-dry well once cooked and cut small. The ham page covers how.

Safety: Cook bacon before drying, as with all meat. Treat home-dried bacon bits like cooked bacon: keep them cool and sealed, and throw them out if they smell stale or sharp.

What to do instead

  1. If you want bacon bits for a trip: cook crisp, blot hard on paper towels, crumble, dry, and eat within weeks.
  2. For long storage, buy commercial shelf-stable bacon bits or canned bacon.
  3. Or dry lean Canadian bacon or ham instead.

Bag smells stale

Rancid fat. Throw it out.

Oil pooled in the bag or on the tray

The bacon was not blotted enough. Fat that melts out during drying stays in the food. Blot again on fresh paper towels before bagging, and use those bits first.

Can I freeze-dry raw bacon?

No. Like any raw meat, cook it first. Freeze-drying does not kill bacteria, and raw bacon would still be mostly fat.
