How-To: Dehydrating Frozen Vegetables

Frozen vegetables are usually picked and flash frozen immediately after the blanching process. The easy part of doing frozen vegetables is that they’ve already been washed, cut, and blanched for you. If you have a freezer full of blanched vegetables from your garden, this is an excellent way to clean it out and have more space for this year’s crops!

As long as these vegetables have been properly stored in your freezer, they will have the same dehydrated shelf life as fresh. Just make sure the store-bought bags do not have any additives/oils/fats that would impede the dehydrating process and cut down on the shelf life. Remember, anything with oils or fats will turn rancid eventually.

There are many reasons to dehydrate frozen vegetables.
1) Sometimes it is the only way you may be able to get a product that does not grow in your region.
2) You live in a metropolitan area and do not have a garden or access to Farmer’s Markets.
3) Since frozen vegetables are picked at the peak of flavor, already prepped, and then flash frozen, they are fresher and easier to prepare.
4) Some who would not be able to stand in the kitchen for all the prep work of the vegetable’s fresh counterpart CAN still dehydrate frozen foods.
5) There is far more nutrition saved in frozen foods then canned foods.
6) There are far fewer additives in frozen foods compared to canned.
7) Frozen foods mat be far less expensive than its fresh counterparts.
8) Dehydrating frozen vegetables allows you year-round access to many foods!

Thaw or partially thaw frozen vegetables that need to be cut up into uniform pieces (like broccoli and cauliflower florets). Otherwise, you should be able to hit the bag against the countertop a few times to loosen and separate the vegetables.

Spread on dehydrator trays in a single layer. For foods such as chopped broccoli or green peas, use a non-stick mesh sheet on the trays to keep drying vegetables from dropping through mesh sheets.

Dehydrate at 125 F/50 C for 6 to 12 hours or until crisp dry. Allow to cool.

Store vegetables in air-tight container(s) away from heat, humidity, and light.

      Although not considered optimal for dehydrating, you can do so AS LONG AS the ingredients do not contain oils or fats.

      Drain, rinse thoroughly, and dehydrate.

      Thank you! Glad you are enjoying it.

      If stored properly, up to 5 years.

      I have never found a frozen vegetable or fruit I have not been able to do this with as long as they do not have any additives.
