How to Make Homemade Soy Milk

Picture of How to Make Homemade Soy Milk
Soy milk is a very healthy addition to anyone's refrigerator. It is filled with nutrients and a great beverage for work, school, or anytime. Store-bought soy milk can get pretty expensive especially compared to regular cow's milk. Soybeans, on the other hand, can be found for a much better price and can even be bought organically. I will show you how to make your own (organic) soy milk and the great thing is you don't even need to spend money a soy milk machine. Soy milk is very simple and easy to make and can be used in many other yummy, healthy desserts, too.

Step 1: Ingredients

To make about 2 quarts and 1 1/2 pints of soy milk, you will need:
  • 1 cup of soybeans (I bought my soybeans for $0.89 a pound- so this recipe would only cost about 2 quarters :)
  • 11 total cups of water (this will be added two to three cups at a time)
  • 1/4 cup of sugar (this probably will be adjusted according to your tastes- not pictured)
Some equipment is also needed but nothing you can't find in your kitchen :)
  • A blender
  • A pot (should be fairly big and be able to hold at least 11 cups)
  • Multiple bowls
  • A cheesecloth (this is for straining the mixture so other items could be used in place of this, like a strainer)
  • A wooden spatula for stirring
  • A container for holding the finished soy milk

Step 2: Preparation

Pour the soybeans and 2 of the 11 cups of water into one of the bowls (make sure there is enough room for the soybeans and 1 cups of water and the water covers the top of the beans). Soak the soybeans for at least 8 hours (if I have the time, I would even soak it overnight). Be sure to add more water if the water level falls below the level of the soybeans.

I made this and it's great. I hate buying store products that are often laced with sugar, preservatives and oil. I made mine sugar free and use it with smoothies and make porridge with it. Thanks again.

Thanks for this. I haven't tried your recipe yet, but it sounds good. The reason I'm writing, though, is to remind people that soy milk can boil over really quickly, so you need to pay close attention at this step if you don't want a mess!

I just made the milk but was wondering if it is ok to eat the soy paste? Any opinions?

how long does this last in the fridge

Could you use canned soybeans?

joy.shipeolu2 months ago

How long can it stay,could it be up to 30 days

no only keep it for 2 to 3 days but trust me we drink it so fast that our house can barely keep up with the demand. In our fridge is a mason jar of almonds soaking and a jar of almond milk being consumed. we add 1/4 cup organic sugar and 2 teaspoons of vanilla and blend one more time before storage.

thanks for this!

What kind of soy beans you're using? it seems that the ones I use look different. Whiter and smaller I think. Are you using the green soy beans?

i made this and was thrilled , but the soya milk is no good in coffee, even if put in before the hot water, it curdles and forms a curd, any ideas? would this recipe be better as a smoothie ? i really want to move from dairy to soya because of animal abuse.

try homogenizing it with some coconut oil(refined). To do so, put the milk into the blender and slowly drizzle the oil in. Taste here and there for consistency but for a coffee creamer, a good start is around 1/2 a cup or so. This is especially good if you add the sweetener to the milk and a little bit of vanilla. With that, you have a nice vanilla flavored creamer for your coffee. Add a little cinnamon and it changes the whole game. Not into vanilla, use some cocoa powder or hazlenut extract. I hope this helped!

When you bake with this do you use the same amount you would use of cowmilk?

yup! soymilk is the standard over almond milk and the likes because it is able to sub out the same. It also curdles like regular milk, so if you need a quick buttermilk, add some lemon juice and you're set!

If you want to thicken it a bit, get some organic refined coconut oil and add a fat content. Each quart, maybe a 1/4 to a 1/2 cup of the oil. When doing it, keep the milk in the blender and slowly add the oil until it is incorporated. You can add more to make it thicker. It's just like the fat content in dairy milk! I think soymilk is somewhere around skim and 2% fat content.

I think so...I haven't done that before, but I've heard the proportions are the same. If you want whole milk, maybe add some butter but other than that, go for it!

These instructions are great! Is the sugar (or any sweetener) actually required? I'm on a diet where I can't have any kind of sugars or sweeteners.
jen7714 (author)  mccreeryj13 months ago

It is definitely not required, so it's up to you and your tastes.

Thank you for sharing the procedures. Do we need to wash the soy beans first before soaking it? Some of the beans float, are these okey to include?
jen7714 (author)  mnesperos3 months ago

You can definitely do an initial rinse, but no intense washing is necessary. And floating beans are fine!

Thanks for the information! I have just some questions. How many days will it take before it spoils? And how to prolong? Thanks again and GOD BLESS!!

I would probably say that it's the safest to consume it within a week. However, definitely complete the boiling step while you're making the batch and also refrigerate it. Thanks for the nice comment!

Does the "boil" step have to be followed? Doesn't this destroy some of the natural enzymes?
jen7714 (author)  Berbatiotis2 years ago
I am not sure if it destroys natural enzymes, but it is much safer to boil the soy milk. Consuming raw soy milk can be dangerous because of possible dangerous bacteria.
mhippo jen77142 years ago
There are certain enzymes in raw soymilk that reduce your body's abbility to digest the milk (trypsin inhibitors, if you care).

By that same logic, one should avoid lima beans as they contain trypsin inhibitors as well.

I made soy milk this morning, my first time actually. Only, I did not strain it. the whole thing was a disaster! Now I know What I did wrong.

Smeiyappan1 year ago
Thanks for the recipe. Yet to make it. How long can we refrigerate this?
jen7714 (author)  Smeiyappan11 months ago
It's the safest to only keep it for a week, but if you don't notice anything different about it and you heat it up, it can be kept for longer.
This is great! A real money saver! Is the sugar necessary?
jen7714 (author)  genies jinn11 months ago
Nope! It's just according to your taste!

Can I use roasted soy beans to make soy milk?
jen7714 (author)  sschrybu11 months ago
Unfortunately, you cannot :(
Sue19651 year ago
Thank you very much for this helpful instructions, I just I made my first soya milk today based on your steps provided. My question is what am I going to do with the extra pulp, I already blended up to 11 cups, that includes the 2 cups for soaking. Will i still blend it with additional cups of water? How many cups.

am excited -Sue
jen7714 (author)  Sue19651 year ago
If you find that adding water and blending again does not water down the soy milk too much, go for it! I would try to go for 1 cup at a time.

This is my second batch of soy milk with this recipe. Thank you so much for posting it! My boyfriend and I really liked the last batch, but I'm substituting sugar with agave to see how it goes because we both found the original recipe a bit sweet.

I have trouble telling when it is ready though! I find I have to boil and then simmer it for closer to 5-10 minutes to get rid of that raw beany taste. What's your clue for when it is best to take it off the stove? :)

jen7714 (author)  emilyrhorn1 year ago
Hey! Thanks so much for the nice comment! As for the boiling time, it really is up to your taste. Just make sure it boils for a bit for health reasons (to ensure that you're not drinking raw soy milk).
I just made my first batch of soya milk.I flavored it with cinnamon and i enjoyed it thank you for sharing with me.
jen7714 (author)  Blackbeauti1 year ago
Awesome! Thanks for trying it out!
Thank you!!! I just finished my first homemade soy milk. It taste really good. My kids will love it!
Thanks for sharing. Just made my first batch and it turned out great! :)
