How to freeze dry broccoli
A typical batch of broccoli runs about 30 hours in a home freeze dryer, plus about 3 hours of extra dry time. Plan on about 12 months (1 year) of good quality for freeze-dried broccoli, 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.
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.

How do you prep broccoli for freeze drying?
Cut into small florets and blanch briefly, then cool and pat dry.
How do you load broccoli on the trays?
Spread florets with space between them. Thick stems should be sliced thin. Run broccoli in its own batch, because its odor carries to other foods.
How long does it take to freeze dry broccoli?
A typical batch of broccoli runs about 30 hours in a home freeze dryer, plus about 3 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 broccoli?
Pack right after the batch finishes, while the pieces are still crisp. For long-term storage, use a mylar bag or a jar with an oxygen absorber. A jar without an absorber is short term, about a month. Keep it somewhere cool and dark.
What is the shelf life of freeze-dried broccoli?
Plan on about 12 months (1 year) of good quality for freeze-dried broccoli, 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 broccoli?
Soak in warm water ten minutes or add to soups and casseroles.
