How to Dehydrate Vegetable Stock

Dehydrate vegetable stock (or broth) to create a shelf-stable soup base for meals in a jar recipe, hiking and camping meals, and having long-term food storage from homemade stock. It’s a great way to use leftovers and avoid food waste, too!

How to Dehydrate Vegetable Stock

Start with the veggie broth of your choice. If you need a basic recipe, you can get one here to print off.

Starting with your homemade broth, follow these steps:

Step One: Condense Broth

• Place broth into a saucepan or stockpot
• Simmer on medium to medium-low until the broth becomes a thick liquid. You don’t want a thick molasses type syrup but think pancake syrup instead. This could take two hours to eight hours depending on your temperature and the amount of stock you are trying to simmer down.
• Check hourly until you are down to the last inch of liquid and begin checking more often as the last few minutes change quickly.

Step Two: Dehydrate Broth

• Pour the thickened liquid onto fruit leather sheets of your dehydrator. A lipped tray like this one works great, or you can make your own like this, or just using a shallow pan or dish will work.
• Dry at 140°F / 60°C until you get what looks like hard candy. No tackiness, breaks easily, glassy surface.
• Break broth into shards and store in an airtight container until you want to powder it.

Step Three: Powder Broth

• Place shards of broth into a small grinder. A coffee grinder or a bullet blender work best for this work. Large blenders and food processors will likely be too big to work effectively
• Plus until the shards have broken into small pieces, then whirl until powder. It may take a time or three to get it completely broken down, depending on your machine. You can sift it if you need to, but I find that having it completely powdered is not important as it will still measure and melt fine.
• Condition the powder.
  • Place powder on a cookie sheet in an oven that has been preheated to its lowest temperature, and then turned off.
  • Sit for 20 min.
  • Allow to powder to cool, break up any clumps with a fork.

Store Dehydrated Vegetable Broth

Because of the sugars that can develop with this powder from the simmering process, vegetable stock powder can become clumped pretty quickly. Here are some helps:

• Store in an airtight container that is similar in volume to your powder (no large containers for small amounts of powder)
• Store in a zipper-top freezer bag inside an airtight container.
• Use arrowroot powder to help work as a desiccant. Know that it may cloud your stock when reconstituting, and work as thickener in what you put it in, so don’t use this stock to can with later.
• Use a moisture absorber in the jar.

Reconstitute Vegetable Broth Powder

To reconstitute the powdered vegetable broth,

Ingredients:

• 1 cup boiling water
• 1 teaspoon vegetable broth powder

Directions:

1. Place 1 teaspoon of vegetable broth powder into a heat-safe container.
2. Pour 1 cup of boiling water over broth
3. Stir until powder is dissolved.
4. Add any additional seasonings you would like. This is a good time to add salt to taste for your final product.

Notes:

You can use more powder to create a more intense broth depending on your taste. Since powder will always be a little different from batch to batch, and concentration, you’ll just adjust to taste.

Dehydrate Vegetable Broth Leftover Vegetables

Yes! You can dehydrate the vegetables left from making vegetable broth! If you are wanting to not waste a thing, and don’t compost or have stock animals that you can feed this to, you can certainly dehydrate the vegetables to add to your vegetable powder!

Unlike making a meat broth, the vegetables still contain flavor, while many vitamins and minerals will have been transferred to the broth.

While the overall flavor of the individual pieces is best described as ‘soup’, you can still taste the individual notes of each piece. So the carrot pieces still taste of carrot in the background.

Directions:

• Place vegetables on fruit leather sheets or parchment paper on your dehydrator trays.
• Dry at 140°F / 60°C along with your broth.
• If you are doing this separately from the broth, you can drop the temperature down to 125°F / 57°C as you would other vegetables.
• Dry until crisp.
• Condition
• Store in an airtight container until you are ready to powder
• Powder as you would vegetable powder and store accordingly.

Frequently Asked Questions:

What should be in vegetable broth?

You can get a full recipe here for a basic vegetable stock mix, but you can use just about any ‘soup’ vegetable, but stay away from starchy ones that can cause cloudiness or strong-flavored ones like broccoli.

What kind of dehydrator do I need?

I happen to use an Excalibur dehydrator, but you can use any dehydrator. A Nesco or Cosori are other great options for most folks.

If you need help choosing which to get, I have the best dehydrator resource for you here with breakdowns of types and best ones in every budget.

How long will Vegetable Stock Powder last?

By best standards, powders are good from six to nine months. However, I would encourage you to store the shards as they are less susceptible to clumping. However, with enough arrowroot and moisture absorbers, you will get a good six to nine months out of your powder easily.

Can I do this with chicken, beef or brone broths?

You can dehydrate chicken, beef, and other protein-based broths, as well! The only thing that will be different is how you store it. By the safest dehydrating standards, these broth powders should be stored in your freezer for storage.

Create your broths, allow to cool and defat, follow the rest of the procedures and store in the freezer when done.
