How to Dehydrate Rice [& Why You’ll Want To]

The first time I heard someone talk about dehydrating rice, I thought to myself:

“You’ve GOT to be kidding me. That’s taking it too far.“

What I failed to realize was that dehydrated rice = instant rice! Yes, just like the popular brand you get at the grocery store.

Why Dehydrate Rice?

It is SO convenient to have rice on hand that can be ready in less than 5 minutes—and you can achieve that at home with your dehydrator.

“Minute rice” is just cooked rice that’s been dehydrated.

When you’re ready to whip up a rice dish, it’s easy to rehydrate. Simply add boiling water or broth to the dried rice and let it sit for a few minutes until the rice has absorbed the liquid. 

We try to keep two, half-gallon jars of dehydrated rice on hand at all times for our “just add water” meals in jars. 

Preparing Rice for Dehydrating

Before you start dehydrating, you need to prepare the rice properly. Follow these steps to ensure your dehydrated rice turns out perfectly every time. 

Cooking the Rice

The first step is to cook the rice. You can use any type of rice you like, such as basmati, white rice, or brown rice. However, keep in mind that different types of rice have different cooking times and water requirements.

You can use either water or broth. If you use broth, the rice will have more flavor. I recommend adding a teaspoon of salt if you are using plain water. 

Here are the basic steps for cooking rice:

1. Rinse the rice well until the water runs clear.
2. Bring the water or broth to a boil.
3. Add the rice and salt if using plain water.
4. Cover with a lid and simmer for the recommended time according to the rice type. For example, white rice usually takes 18-20 minutes, while brown rice takes 35-40 minutes.

Alternatively, you can use a pressure cooker (like an InstantPot). Use equal parts rice and water, add a tablespoon of butter, and a teaspoon of salt. Seal and pressure cook for 6 minutes. Allow for a natural release of the steam. Done!

Adding Flavor

If you want to add more flavor to your dehydrated rice, you should do so before cooking. Here are some ideas:

• Add spices such as garlic powder, onion powder, or cumin to the cooking water or broth.
• Add diced vegetables such as carrots, onions, or celery to the cooking water or broth.
• Cook in beef broth instead of water.

How to Dehydrate Rice Two Different Ways

While a dehydrator makes it easy without heating your kitchen, an oven is certainly an option. First, let’s talk about using a dehydrator. 

Using a Dehydrator

1. Cook your rice as you normally would.
2. Spread the rice out on your dehydrator trays.
3. Set your dehydrator to 125°F (or follow your dehydrator’s instructions), and dry the rice for 8-10 hours or until it is completely dry and brittle. I usually let the dehydrator run overnight. 
4. Once the rice is dehydrated, store it in an airtight container with an oxygen absorber.

Using Your Oven

If you don’t have a dehydrator, you can still dehydrate rice using your oven. Here’s how:

1. Preheat your oven to the lowest setting it will go—preferably under 150 degrees F. 
2. Cook your rice as you normally would.
3. Spread the rice out on a baking sheet lined with parchment paper in a single layer.
4. Place the baking sheet in the oven, and leave the door slightly open to allow moisture to escape.
5. Dry the rice for 5-7 hours or until it is completely dry and brittle.
6. Once the rice is dehydrated, store it in an airtight container with an oxygen absorber.

When using your oven, keep a close eye on the rice to ensure it doesn’t burn.

Regardless of your dehydrating method, store your instant rice in an airtight container such as a Mason jar. For long-term storage, use an oxygen absorber or vacuum seal it. 

In an oxygen-free environment, instant rice can last several years. 

How to Use Your Homemade Instant Rice

Congratulations on successfully dehydrating your own rice! Now, it’s time to learn how to use it. 

When you’re ready to cook, use equal parts water and rice. Bring it to a boil, then lower to a simmer and cook for 5 minutes. Fluff with a fork and serve!

Your homemade instant rice can be used in any recipe that calls for cooked rice. Here are some ideas:

• Fried rice: Heat a little bit of oil in a pan, add your choice of vegetables and protein, and sauté until cooked. Add your rehydrated rice and stir until everything is well combined. Season to taste with coconut aminos or soy sauce, salt, and pepper.
  
• Curry-seasoned rice: Add your favorite curry seasonings to your rehydrated rice and stir until well combined. Serve as a side dish, or use as a base for a curry bowl.
  
• Sushi rice: Season your rehydrated rice with a mixture of rice vinegar, sugar, and salt to make sushi rice. Use it to make your favorite sushi rolls.

DIY instant rice is also the perfect addition to your meals in jars!

Frequently Asked Questions

How long does dehydrated cooked rice last?

Dehydrated cooked rice can last for years if stored in a vacuum-sealed Mason jar.

Keep the container in a cool, dry place away from direct sunlight and moisture. For regular use, you don’t have to vacuum seal it or use an oxygen absorber. It will last up to 6 months as-is when stored in a sealed container. 

What is the best type of rice to dehydrate?

White rice is the best type of rice to dehydrate because it rehydrates faster than brown rice. However, brown rice can also be dehydrated, but it takes longer to cook and rehydrate. 

It also doesn’t store well long-term due to the oils in it. 

Can I dehydrate other grains like brown rice or risotto?

Yes, you can dehydrate other grains like brown rice or risotto. However, the cooking time and dehydration time will vary depending on the type of grain and the moisture content. 

The dehydrating process will be the same though.

Enjoy!
