Sometimes we buy packaged food for convenience, and sometimes we believe that prepare them ourselves have to be difficult and expensive. This homemade soy yogurt is a clear example of how easy it can be to prepare food at home and in addition, we can save money.
To make homemade soy yogurt you're gonna need only two ingredients: soy milk and a starter (you can use store-bought or previously homemade soy yogurt or a yogurt starter powder). So simple and cheap.
I used to buy organic soy yogurt and it was quite expensive, but now I only need homemade soy milk and a homemade yogurt. That's all!
You only need to buy a store-bought yogurt or a yogurt starter powder for the first time, then you can use your own homemade soy yogurt as a starter.
You can also make homemade yogurt with others plant milks, we also make yogurt with coconut milk and a yogurt starter powder (we couldn't find coconut yogurt), it's really creamy, sweet and delicious.
We've used homemade soy milk, it's so cheap and easy to make, and it tastes so much better than store-bought, you should try! We'll share the recipe soon. Use not transgenic or genetically modified soy milk and with no additives, preservatives or sugar, you can add healthy sweeteners such as dates, stevia, coconut sugar, maple or agave syrup, etc.
We've used a teaspoon of agar agar powder for a thicker yogurt, but you can use other thickeners such as tapioca flour, carrageenan, corn starch or corn flour, xanthan gum, flax seed, etc. You can add more or less thickener, it depends on the consistency you want.
I have good news for you, you don't need any equipment, if you have an oven, you can make homemade yogurt! You only need to preheat the oven at 50 º C or 120 º F for a few minutes, turn off the oven and place the yogurt inside for about 8 hours.
You can add fruits, seeds and nuts to your yogurt, so it will be even healthier and more nutritious. This time we've added nuts, sesame seeds and goji berries, we love them!
We recommend you to make homemade soy yogurt, it's cheap and easy, and also it's healthy, creamy and it tastes amazing! If you don't like the soy flavor you can make homemade yogurt too, you only need your favorite plant milk and a yogurt starter powder and you'll make the best yogurt you can imagine. Seriously, it's awesome!

Soy Yogurt
Ingredients
- 4 cups soy milk
- 1 teaspoon agar agar powder
- ½ cup soy yogurt, or yogurt starter powder (the amount may vary, follow the package instructions)
Instructions
- Preheat the oven at 50º C or 120º F.
- Pour the soy milk in a saucepan, add the agar agar, stir and heat the mixture to 90º C or 195º F, but be careful because it shouldn't boil. You can use a thermometer, but it's not necessary.
- Pour the mixture in a bowl and let it cool to 40 or 50ºC (105º F or 120º F). If you don't have a thermometer you can put your finger in the mixture and when it's hot but not burn it's ready.
- Add the starter (soy yogurt or yogurt starter powder), stir and pour the mixture into glass jars or containers.
- Turn off the oven, place the glass jars or containers (without lids) inside and let stand for at least 8 hours. You mustn't open the oven during this process.
- Now you can cover the jars or containers and keep the yogurt in the fridge.
Anjani says
Can I use probiotics capsules instead of yogurt starter? If so, how many should I use?
Iosune says
Hi Anjani! I think it should work, but I can't help you because I've never used them to make this recipe, sorry!
Georgina Shoebridge says
Hi I have just found your great blog! 😊
I have already purchased a 1.2 litre yogurt maker as think it would me easier than filling lots of small pots and have made my first batch. It was quite thick but stage two after the 8 hour fermentation requires putting it through the strainer to achieve “Greek yogurt” (institutions are based on cows milk. This is a pain and also makes the process much longer!
I prefer the idea of just throwing the ingredients in, stir and go and not have to heat up before hand (plus not sure if would be too hot for the plastic inserts). I have tapioca flour too so if used this how much would I need based on 1ltr of milk and could I just pop it in before turning it on?
Many thanks
Georgina
Iosune says
Hi Georgina! I'm so sorry, but I can't help you, as I've only made the recipe as you can read on the post. Have a nice day!
Sofia says
Hi,
I followed all your instructions and my yogurt didn't set. Will there be a reason why?
Thanks
Iosune says
Hi Sofia! Use a milk with healthy ingredients, no preservatives, additives or sugar 🙂
Camile Ayre says
Simple, easy and works as well as more pretentious recipes.
Iosune says
Hi Camile! Thanks a lot 🙂
katykat1982 says
Hi! Thank you for the recipe 🙂 Im not vegan, Im just trying not to eat gluten or dairy as I find I feel better when those are not a part of my diet. I still consume meat, so for my thickener I used gelatin powder and my yogurt is currently in the oven for the night. Fingers crossed! I had a store bought soy yogurt by Silk today and was instantly hooked! I dont like sour yogurt so the comments that say their didnt come out sour has me excited! I used organic vanilla soy milk, a vanilla soy store bought yogurt as the starter and gelatin as a thickening agent. If I can remember to follow up, I'll let you know how it turns out 🙂 Thank you again!
Iosune says
Hi! You're so welcome 🙂 Hope you enjoy it!
Jane Kingston says
Hi. I had a go at making the soy yoghurt. I used a dairy free yoghurt starter and followed the recipe but it did not thicken. I used xanthum gum as the thickener. It is only my first time but I would like to try again. What am i doing wrong?
Iosune says
Hi Jane! You should use agar powder instead of xanthum gum and follow all the steps 🙂
Allegra says
You can use soaked cashews as a thickener too and for an added nutrient boost! We make ours with a cup or cashews soaked overnight in warm water and then pulses with the ingredients. It helps it get more or a Greek yogurt flavor and texture.
Iosune says
Hi Allegra! Thanks for your comment 🙂
Ashley Abbott says
I followed this recipe to a T and though it firmed up, it didn't taste like yogurt. It tasted like coagulated soy milk. What could've happened? The tangy sour yogurt flavor wasn't there.
Iosune says
Hi Ashley! Was your soy milk made with just soybeans and water? Did you use a thermometer? I'm so sorry the recipe didn't work for you.
Antoinette Heilman says
This is a great recipe. I have questions though. How long does this yogurt last? When you use the left over yogurt from last bath does it spoil when it goes into your new batch?
Iosune says
Hi Antoinette! Thanks a lot 🙂 It lasts up to a week. No, it doesn't 🙂
v says
I'm making the soy yogurt, it's in the oven now. My question has to do with the nutrition info for the recipe. It specifies 4 servings, each with 52 calories, 2g protein. The 4 c. soy milk & half c. soy yogurt I used to make the recipe had a total of 470 cal. & 33 g. protein. Divided by 4 equals approx. 117 cal. & 8g. protein per serving. I don't believe you could have found that much soy TOTALING only 8g. protein 208 calories. Please explain.
Iosune says
Hi V! The info was wrong, sorry! I've used this web this time: https://www.verywellfit.com/recipe-nutrition-analyzer-4157076
Judit says
Hola!
Podrias decirme que marca de starter utilizas? Y donde lo compras?
Muchas gracias!
Iosune says
Hola Judit! Lo compré hace años en una farmacia y no recuerdo el nombre, lo siento! Ahora prefiero usar yogur de soja 🙂 Un saludo!
Yareli says
Would it be okay if I freeze some of the yogurt to use later as starter?
Iosune says
Hi Yareli! I've never frozen it myself, so I don't know, sorry!
Fabio says
Hi
I'm a huge yoghurt fan and letting it go after veganism was a "sacrifice".
Thank you so much for sharing this recipe!
Just a question: how do they last in the fridge?
Iosune says
Hi Fabio! You're so welcome 🙂 They last pretty well, for a few days. Have a nice day!
