Soy yogurt is an easy dairy-free yogurt alternative. It’s the only dairy-free milk that will naturally thicken as it cultures! Make flavored yogurt by adding in flavor extracts, spices, and sweeteners. See the section above for 6 flavor suggestions.

Ingredients

Units Scale
  • 2 Tbsp of vegan yogurt with live culture
  • 4 cups of soy milk (see notes)

Instructions

With a yogurt maker

  1. If you have a yogurt maker, then you can simply mix the soy milk and yogurt culture, then let the yogurt maker heat it to the right temperature.
  2. Maintain at around 105F (40 C) until it is set (at least 4 hours, or if you like a strong yogurt then you can leave it for up to 24 hours). The soy yogurt should have thickened. 

Without a yogurt maker

  1. Pour the soy milk into a small saucepan and warm it up on medium-low. The soy milk needs to get to 105 F (40 C) without burning. So heat it slowly, and whisk occasionally to keep it from scalding on the bottom of the pot.
  2. When the soy milk is at 105 F (40C), stir in the yogurt culture making sure it is well mixed. 
  3. Pour the warm soy milk into mason jars or serving containers.
  4. Keep the yogurt warm until it is set (at least 4 hours). Wrapping it in sweaters and sticking it next to your hot water tank works well! The soy yogurt is done when it has thickened slightly. 

Notes

  • Using soy milk that is labeled as Preservative-Free is the best way to make sure that added preservatives don’t slow down or stop the culturing. However, I have never had an issue with using fresh soy milk, found in the refrigerated section of the grocery store. Alternatively, you could try homemade soy milk. Just avoid using shelf-stable soy milk.
  • Soy milk forms a fairly thick yogurt without any added thickeners. However, if you want really thick creamy yogurt, strain the extra liquid. Line a colander with two layers of cheesecloth and pour in the soy yogurt. Leave it to drain for 2-3 hours. The soy yogurt will be extra thick and creamy. And the liquid can be used as a probiotic culture for fermenting grains and vegetables. It’s also perfect for adding to a smoothie.
  • To make a flavored yogurt, stir in spices, flavor extracts, cocoa powder, etc. prior to fermenting. Fruit, nuts, and granola are better added when serving the yogurt. See the section above for 6 delicious flavor options.
