Freeze Drying Sweet Potatoes

The poor sweet potato. It’s not pretty so it’s often overlooked as the nutritional powerhouse that it is. Sweet potatoes are not only one of our favorite foods, dogs love them, kids love them, and they are the secret weapon of those in pursuit of weight loss without deprivation.

Sure they’re strangely misshapen, but are packed full of vitamin A, vitamin C, manganese, copper, pantothenic acid and vitamin B6. They are a good source of potassium (which can be hard to get), dietary fiber, niacin, vitamin B1, vitamin B2 and phosphorus.

Convinced? Freeze drying sweet potatoes is so easy. Just slice them about 1″ thick and place them in a single layer on the freeze drying trays. Store them in airtight containers until you’re ready for them.

One of the best ways to use freeze dried sweet potatoes is to make them into mashed sweet potatoes with butter and cinnamon. If that’s your plan, you can grind freeze dried slices into a powder then just add hot water. While you have a stash of sweet potato powder, sneak a couple of tablespoons into your smoothies for a nutritional boost.

Keep a stash of freeze dried sweet potatoes around for a low calorie, high fiber snack when the 3 o’clock munchies hit. Trust us, it works.

One of our favorite simple sweet potato dishes is just a combination of lentils, curry powder, sea salt, and diced sweet potatoes over rice. Sliced very thinly, they make delicious vegetable chips when sprinkled with savory seasoning, or a sweet treat tossed with cinnamon and sugar.

Enjoy the beautiful fall weather, and enjoy stashing some seasonal treats for the winter days ahead.

With fresh sweet potatoes we like to do a quick blanch before freeze drying. This helps retain color and flavor. Frozen vegetables have already been blanched and so we put them strait into the freeze freeze dryer.

My dad has been complaining about how hard it is to cook for one, so being able to make a batch and then split after cooking has been helpful.
I cooked and mashed sweet potatoes, butternut squash, and pumpkin and then put on trays. To speed drying, I put spoonfuls with space between them. I was amazed at how sweet the powder tasted when dried.
I gave him bags of powder with some small cans of coconut milk to make soup.

I did not blanch my sweet potatoes before freeze drying. I ground them into a powder and want to use as a puree. Can I do this even though I did not blanch them?

I’ve been making sweet potato powder for a long time . It’s a dense powder that makes a perfect bag to store. I steam my taters first, then put on trays to cool. My wife wants them straight, without any extras, which can be added later. But we have SO MANY fresh sweet taters that we never look for the FD ones. Oh well, someone in the future will be well fed!!
There are hundreds of sweet potato stews you can make, all yummy, esp. with lots of garlic and onions.

i cook them in a roaster with skins on. Once they’ve cooked the peel comes off super easy. I put the right onto the FD tray and mash with a fork. Takes about 34-37 hours to FD (I prefreeze mine). i have been breaking them into small 1” squares and pkg them in mylar bags or mason jars. I’ve rehydrated them and they taste fresh from the garden! I wondered how they would rehydrate if I powdered them… that would take way less space to store!
