How to freeze dry cheese
A typical batch of cheese runs about 30 hours in a home freeze dryer, plus about 4 hours of extra dry time. Plan on about 3 months of good quality for freeze-dried cheese, as long as the food is fully dry, sealed in an airtight container or mylar bag with an oxygen absorber and stored cool and dark. These are typical estimates from the FreezeLog guide, not exact times or a safety limit. Read the safety note below before you start.
General guidance only. Follow your freeze dryer manufacturer's instructions and current food-safety guidance. These are rough figures, not a promise that any food is safe to store or eat. Actual results depend on your machine, load, packing and storage.

Safety note
High-fat foods can turn rancid even when dried. Treat the shelf life as a short default, keep the product cool and dark, and discard anything that smells sharp, soapy or stale. Cheese is also perishable dairy.
How do you prep cheese for freeze drying?
Use pasteurized cheese only. Shred it or cut it into very small cubes. Melt or blend high-fat cheese and spread it thin so it dries evenly.
How do you load cheese on the trays?
Spread small pieces with space between them.
How long does it take to freeze dry cheese?
A typical batch of cheese runs about 30 hours in a home freeze dryer, plus about 4 hours of extra dry time. Your machine and load will differ, so check that the batch is dry before you pack it. Here is how to tell when a batch is done.
How do you store freeze-dried cheese?
Pack immediately in a sealed mylar bag with an oxygen absorber and keep it cool and dark. Dairy takes up moisture quickly, so work fast and avoid opening the bag often.
What is the shelf life of freeze-dried cheese?
Plan on about 3 months of good quality for freeze-dried cheese, as long as the food is fully dry, sealed in an airtight container or mylar bag with an oxygen absorber and stored cool and dark. That is an estimate of quality, not a safety limit.
How do you eat or rehydrate freeze-dried cheese?
Use dried cheese in sauces and baking, or crumble over dishes.
