I've been soaking nuts and seeds for years since I learned about the likely benefits. During that time, I've heard that it might not be as beneficial as I originally thought, but the soaked nuts are lighter and crispier, the touch of salt is just perfect, and they taste fantastic.

So the truth is, regardless of the benefits, I'll keep soaking our nuts and seeds no matter what.

Do You Need to Soak Nuts?

Good question and the short answer is: not always—but it can help in some situations.

Soaking nuts is often recommended to reduce compounds like phytic acid and make them easier to digest. However, there's more research on the benefits of soaking grains and beans than on soaking nuts, and not everyone notices a difference.

Here’s a simple way to think about it:

  • You might benefit from soaking nuts if:
    • nuts feel hard to digest
    • you eat them frequently or in large amounts
    • you’re following a traditional foods or gut-healing approach
  • You might not need to soak nuts if:
    • you tolerate them well
    • you eat them occasionally
    • you prefer the convenience of using them as-is

In other words, soaking nuts isn’t essential—but it can improve texture and digestibility for some people. And it definitely improves taste.

If you do want to soak nuts and seeds, it's super easy to do so. Here's how.

How to Soak Nuts and Seeds (Quick Method)

Here's all you need to do to soak your nuts and seeds.

  • Put nuts or seeds in bowl
  • Cover with water (filtered preferred)
  • Add salt (optional. Salt enhances the soaking procedure and gives your nuts great flavor.)
  • Soak
  • Drain
  • Dehydrate

Soaking Times for Nuts and Seeds

Use this quick chart to find the right soaking time for various nuts and seeds.

Nut / SeedSoaking TimeNotes
Almonds8–12 hoursOne of the longest soaking times
Walnuts4–8 hoursSofter, don’t over-soak
Pecans6–8 hoursHigh fat, moderate soak
Hazelnuts8–12 hoursLonger soak improves texture
Brazil nuts4–6 hoursShorter soak works well
Macadamia nuts2–4 hoursVery soft, don’t over-soak
Cashews2–4 hoursCan get slimy if over-soaked
Pumpkin seeds6–8 hoursCommon for soaking
Sunflower seeds4–6 hoursShorter soak is enough
Sesame seeds4–6 hoursSmall, soak less time

Soaking times aren’t exact—different sources recommend slightly different ranges. In practice, anything within these time frames works well.

Note that chia and flax seeds should not be soaked this way. Instead they are used as egg substitutes and are mixed with water right before using. Flax seeds are usually ground before mixing to make flax eggs while chia seeds can be used as chia eggs either whole or ground.

Special Notes About Cashews

Cashews are a bit different from other nuts. In their raw state, they contain naturally occurring undesirable compounds in the shell that are removed during processing, which is why cashews are typically sold pre-treated.

Because of this, they’re already ready to eat as-is and don’t behave the same way when soaking.

When soaked:

  • they soften very quickly
  • they can become slimy if soaked too long
  • they don’t dry into a very “crispy” texture
  • If you choose to soak cashews, keep the soaking time short—about 2–4 hours is usually enough.

Why You Should be Soaking Nuts and Seeds

  • It helps with digestibility
  • It's easier and takes less time than you think
  •  They just plain taste better this way!

Nuts and seeds are a wonderful addition to your diet. However, they can also be a bit rough on your stomach. That's because they contain phytic acid and enzyme inhibitors that may make them harder to digest for some people.

For some people, soaking nuts can make them easier to digest and improve texture. While it’s not essential for everyone, it’s a simple step that many find helpful.

When seeds and nuts are planted in the ground, the warmth and moisture in the soil around them break down their skins so that they can germinate and grow into plants.  Likewise, soaking nuts and seeds breaks down the encasing of these great sources of energy and make the nutrients more available.

Most of the time spent soaking and dehydrating is hands-off time.  You just put the seeds or nuts in a bowl, transfer them to the dehydrator (or oven), and then take them out when dry.

What About the Soaking Water?

After soaking, the water may look cloudy. That’s normal—it can contain small amounts of natural compounds from the nuts along with fine particles from processing.

Some people prefer to rinse nuts after soaking to remove this residue. Others skip this step, especially if they are drying the nuts afterward.

In my experience, both approaches work. I usually skip rinsing for simplicity and flavor.

How to Dry Soaked Nuts

After soaking, drying the nuts is what gives them that crisp texture and helps them store well.

Spread the soaked nuts in a single layer on dehydrator trays or baking sheets. If you're drying seeds, they can be piled a bit more since they dry faster than larger nuts.

Dry at a low temperature until completely crisp. In a dehydrator, this is typically around 115–125°F. Drying time varies depending on the type of nut, but most take anywhere from 12–24 hours (sometimes longer).

You can also use an oven set to its lowest temperature. Just keep in mind that ovens tend to run hotter and may not dry as evenly.

So while you don't need a dehydrator to dry soaked nuts, it's a much easier way to do it than using an oven. In my post about the benefits of dehydrating I share a lot of tips including how to choose a dehydrator that meets your needs.

Notes and Tips

  • Temperature control is one way in which the dehydrator is a much better option than the oven. Typically the lowest temperature for an oven is high enough to destroy the enzymes in the nuts/seeds, therefore diminishing their healthful qualities. However, if you're not ready to invest in a dehydrator, using your oven is a great starting point.
  • Dehydrator Temperature.  There is debate about what temperature to dehydrate at to preserve the enzymes in your food. For now, I am comfortable with 125. I am not an ardent raw foodist, and after researching this I found that the temperature of the food in most dehydrators is significantly below the temperature of the air around it. Thus, if the setting of the dehydrator is 125, your food temperature is almost certainly in the raw food range which is 115 or below.

Roasting Nuts and Phytic Acid

Roasted nuts are popular because they taste great—but roasting and soaking are not the same thing.

Roasting may reduce some compounds like phytic acid and can make nuts easier to digest. However, it’s unclear how much of a difference it really makes, and results vary depending on temperature and cooking time.

In contrast, soaking is designed specifically to help break down enzyme inhibitors and support digestibility before drying.

Another thing to consider is how store-bought nuts are processed. Many “roasted” nuts are actually cooked in oils, which may not be ideal depending on the type of oil used (most often they are cooked in seed oils).

If you enjoy roasted nuts, a better option is to roast them yourself at a lower temperature. This gives you more control over both the ingredients and the process. Nuts can be more prone to going rancid when roasted at higher temperatures (source). Also, roasting almonds at a higher temperature causes almonds to form a significant amount of cancer-causing acrylamide (source).

Should You Soak Nuts Before Roasting?

If you plan to roast nuts, you may wonder if soaking them first is worth the extra step.

There isn’t strong evidence comparing soaking vs. roasting directly. However, soaking and drying nuts first is a simple way to support digestion—and it gives you flexibility.

You can:

  • eat them as “crispy nuts” after drying
  • or roast them afterward for additional flavor

In my experience, soaking first and then roasting gives the best balance of texture and digestibility.

How to Use Soaked & Dried Nuts aka “Crispy Nuts”

I'm sure you'll agree that your nuts and seeds are much tastier and lighter than before. You will never go back again.

This simple method works for most nuts and seeds. See the soaking chart above for specific timing.

Ingredients

  • 4 cups nuts or seeds
  • water
  • 2 teaspoons salt

Instructions

  • Add nuts or seeds to a bowl. Use about 4 cups, or whatever amount fits your dehydrator.
  • Cover completely with filtered water.
  • Add salt.Use about 2 teaspoons salt per 4 cups of nuts or seeds.
  • Soak for 7–12 hours (overnight works well).
  • Drain (and rinse if desired).
  • Spread in a single layer on dehydrator trays or baking sheets (nuts should be in a single layer, whereas seeds can be piled slightly).
  • Dry at low temperature: Dehydrator: ~125°F Oven: lowest setting
  • Dry until completely crisp. Cool and store for later use.

Notes

  • Salt Amount: Some sources recommend different salt amounts for different nuts/seeds. I just keep it simple and use the same for all of them.
  • Cashews: Soak only 2–4 hours—they soften quickly and can become slimy.
  • Seeds dry faster: Pumpkin, sunflower, and sesame seeds may be slightly piled on dehydrator trays whereas nuts should be dried in a single layer.
  • Drying tip: Nuts should be fully dry and crisp before storing to prevent spoilage.

  1. Can any nuts be used or must they be raw?
    Do you have to use salt in the water soak? my household is a low sodium home and we leave salt out whenever possible

    1. I don’t believe that soaking a roasted nut serves much purpose. But I could be wrong. You could leave the salt out but it does make them very tasty. Soaking and roasting both address digestibility issues but roasting apparently creates free radicals that would not be desired. I hope that helps.

      1. Hi

        I’m not sure if I’m actually worried about a real scenario but……

        The food safety danger zone is the temperature range between 40 °F (4.4 ºC) and 140 °F (60 ºC) in which bacteria can grow rapidly.

        I want to soak walnuts and then dehydrate them at a low temperature so that I don’t damage the fats but that temperature will inevitably be within the food safety danger zone

        What is to stop the walnuts harbouring dangerous bacteria due to being kept at this temperature for so long? Or is there something about the dehydration process that prevents such a thing?

          1. Ah but to dehydrate at a higher temperature would no longer be dehydration. It would be cooking. I must admit I have never heard of an instance where dehydration has caused a food safety concern.

            1. Hi again. Well, I guess that depends on your definitions. I hope it works for you in either case. Thanks!

    1. I soak at room temp. I believe I answered about covering and non after your previous comment. Thanks!

  2. After soaking and dehydrating the nuts how do you store them and for how long? Thank you for sharing all these great recipes.

    1. Yes, if you like. I don’t like my nuts and seeds not dried or roasted, but you can do that.

      1. So it’s basically a texture/preference thing and also for longer (much) storage purposes.
        I will do a dehydrated batch but I think the day to day will often just be
        soaked seeds and nuts with fruit for breakfast.

        Thanks

  3. I understand why to soak them – but can’t find any info about why the need to dehydrate after? I don’t bother with this phase. It just add complexity as far as I can see. I Just let them air dry for a few hours spread out on a clean tea towel and store them in an air tight container in the fridge. they keep a week like this.

    1. I don’t think the nuts would dry completely by doing only this….and they would mold. I don’t really like the nuts when they aren’t dried but of course that’s just personal taste :). If you want them for butters or long term snacking of course drying is the way to go.

  4. Well hello there and a big fat thanks for your time & information 🙂
    I do not have a dehydrator yet, one day I will be contacting you to get that Excalibar however right now, don’t ask me why because I don’t know that answer Ha ha ha but I have a Mac daddy Oven evidently because it goes to a very low temperature of 100*
    So I soaked the Brazil nuts overnight then put them in the oven on 125* at around 10am today…. I had to leave the house at that time and so I left the oven door a little open… ?question? Am I supposed to close Oven door while the nuts are in there dehydrating or leave the door open a bit?? Is it safe for me to leave Oven on when I am not home or when I sleep through the night….. I read to dehydrate them for 18hrs that would end up being 5am, I have to be up at 5:30 to get ready to go so good timing I suppose;) but just wondering if people just leave the Oven on while they are not home or sleeping? 🙂 🙂 🙂 🙂

    1. Hi there. I could not recommend leaving an oven on while sleeping or away from home. I am sure people do it but I don’t think it’s recommended for safety reasons. Sorry :).

  5. How do I dehydrate sunflower seeds and not have them fall through the mesh of the excaliber tray? Ive been using parchment paper on top of the mesh but wondered what other options there were. Thanks.

    1. They have paraflexx sheets which go on top. I can get you a good deal on them if you would like – :).

      1. Yes I’d be interested in finding out how much they are. Then I’d have to see if I can fit it in the budget.

      2. Good Day Adrienne,

        I don’t have a dehydrator yet. I’m soaking some raw sunflower seeds now.
        My toaster oven setting is 200. How long do would i need to toast them? When I dry coconut shreds I do it for 4 hours.

        Thank you for all your amazing recipes and posts!

        1. Hi there. I’m sorry but I haven’t tested it that way – sunflower seeds dry out very quickly so I would check maybe every 20 min or so? Thanks for the kind words.
