I love having jars of dehydrated corn in my pantry.

It takes up less space than canned or frozen corn, does not require freezer space, and is easy to add to soups, stews, casseroles, and other cooked meals.

Dehydrating corn is also a practical way to preserve a good sale, use an abundant garden harvest, or make room in your pantry and freezer.

You can dehydrate fresh, frozen, or canned corn. Each one requires slightly different preparation, but the process is simple once you know what to do.

Why Dehydrate Corn?

There are several reasons I dehydrate corn:

• It takes up very little pantry space.
• It is shelf-stable when dried and stored properly.
• It is easy to add to cooked meals.
• It helps me use canned foods before their quality begins to decline.
• It frees up valuable freezer and pantry space.
• It allows me to stock up when I find a great price.

Years ago, a friend found several #10 cans of corn marked down at Walmart and grabbed them for me.

Even with 12 children, a #10 can was more corn than we needed for one meal. Dehydrating it allowed me to preserve that bargain without wasting the corn.

Supplies You Will Need

• Fresh, frozen, or canned corn
• Food dehydrator
• Dehydrator mesh screens or tray liners
• Colander
• Large pot and bowl of ice water for fresh corn
• Sharp knife and cutting board
• Clean, airtight storage containers
• Labels and marker

Small corn kernels can fall through dehydrator trays, so mesh screens or tray liners are especially helpful.

How to Dehydrate Canned Corn

Canned corn is one of the easiest options for a beginning dehydrator.

Because commercially canned corn has already been heated during processing, it does not need to be blanched again.

Step 1: Drain the Corn

Open the cans and pour the corn into a colander.

Drain it thoroughly. You may also rinse the corn if you want to remove some of the added salt.

Allow as much water as possible to drain away before placing the corn on your trays.

Step 2: Fill the Dehydrator Trays

Spread the corn in a single, even layer.

Separate any clumps and avoid piling the kernels on top of one another. Good airflow helps the corn dry evenly.

Step 3: Dehydrate the Corn

Set your dehydrator to approximately 140°F.

Drying time can vary based on your dehydrator, humidity, tray load, and how much moisture remains in the corn. Begin checking it regularly after several hours and rotate the trays if your dehydrator requires it.

The corn is finished when the kernels are hard, crisp, and completely dry. Properly dried corn should shatter when struck with a blunt object.

How to Dehydrate Frozen Corn

Frozen corn is another convenient option because commercially frozen vegetables have generally been blanched before freezing.

Check the package to be certain that the corn was blanched or precooked. If it was, you do not need to blanch it again.

Step 1: Break Apart the Corn

Break up any large frozen clumps.

You can place the corn on the dehydrator trays while it is still frozen, but separating the kernels will help it dry more evenly.

Step 2: Arrange It on the Trays

Spread the corn in a single layer on lined dehydrator trays.

Step 3: Dry Until Crisp

Dehydrate at approximately 140°F until every kernel is hard, crisp, and completely dry.

Frozen corn may release extra moisture as it begins to thaw, so drying time will vary. Check several of the largest kernels before deciding that the entire batch is finished.

How to Dehydrate Fresh Corn

Fresh corn requires a little more preparation because it must be blanched before drying.

Blanching slows the enzyme activity that can affect the corn’s flavor, color, texture, and quality during storage.

Step 1: Prepare the Corn

Choose fresh, tender ears of sweet corn.

Remove the husks and silk, then wash the ears thoroughly.

Step 2: Blanch the Corn

Place the ears in boiling water and blanch them for three minutes.

Immediately transfer the corn to a bowl or sink filled with ice water to stop the cooking process. Allow it to cool, then drain it thoroughly.

Step 3: Remove the Kernels

Use a sharp knife to carefully cut the kernels from the cobs.

Do not scrape the cobs. Separate any large clumps of kernels.

Step 4: Fill the Trays

Spread the corn in a single layer on mesh-lined dehydrator trays.

Step 5: Dehydrate the Corn

Dehydrate the corn at approximately 140°F.

Corn commonly takes about 6 to 10 hours to dry, but your time may vary. Humidity, kernel size, dehydrator style, and tray load can all affect the drying time.

The finished kernels should be hard, crisp, and brittle—not soft, chewy, or damp.

Cooling and Checking Dehydrated Corn

Allow the corn to cool completely before placing it in storage containers.

Warm food can create condensation inside a container, adding moisture back into the corn.

After the corn has cooled, check several of the largest kernels. If you find any softness or moisture, return the entire batch to the dehydrator.

Never package corn that is still warm or not completely dry.

How to Store Dehydrated Corn

Place the cooled corn in clean, airtight containers that protect it from moisture and insects.

Good options include:

• Glass canning jars with tight-fitting lids
• Vacuum-sealed jars
• FoodSaver bags
• Mylar bags intended for food storage
• Other food-safe, moisture-resistant containers

Label every container with the contents and the date.

Store the corn in a cool, dry, dark location. Heat, light, air, and moisture can reduce the quality of dried food.

Package the corn in amounts you are likely to use at one time. Every time you open a container, the food is exposed to additional air and moisture.

Check your containers during storage. Discard the corn if you notice condensation, moisture, mold, an unusual odor, or any other sign of spoilage.

How to Use Dehydrated Corn

Dehydrated corn works best in cooked dishes.

You can add it directly to soups and stews that contain plenty of liquid. Give it enough time to soften as the meal cooks.

You can also rehydrate it before using it in other recipes.

To rehydrate dried corn, you can:

• Soak it in cold water for one to two hours, keeping it refrigerated if soaking it longer.
• Add it directly to boiling water or broth.
• Soak approximately one cup of dried corn in 2¼ cups of water for about 30 minutes before cooking.

Drain away any water that your recipe does not need.

Rehydrated corn will not have exactly the same texture as fresh corn, but it is a convenient pantry ingredient for soups, casseroles, chowders, and other cooked meals.
