How to Make Vanilla Yogurt in Your Crock Pot

5 from 16 reviews

Once you try this recipe for making homemade yogurt in your slow cooker, you’ll be amazed at simple and delicious it is.


  • 1/2 gallon milk
  • 1/2 cup yogurt starter
  • 1/2 cup sugar
  • 1 tablespoon pure vanilla extract
  • Cheesecloth and colander (Optional)


  1. Pour 1/2 gallon of milk into crock pot and turn it on low. Let it sit for 2 hours and 45 minutes. Set a timer and walk away from the crock pot at this point.
  2. When the timer dings, turn the crock pot off and unplug it. Whisk in sugar and vanilla. Let the yogurt sit for 3 hours. Again, set your timer and resume your regular activities.
  3. After the 3 hours are up, spoon 1 cup of the milk into a small mixing bowl. Whisk in your yogurt starter. Add this mixture back to the crock pot and whisk it all together.
  4. Put the lid back on the crock pot and wrap the entire crock pot in one or two beach towels. I wrap one around the outside and cover the top with another towel. (The reason being is that it allows the temperature of your yogurt to slowly cool and culture.)
  5. Let your wrapped crock pot sit for 8 to 12 hours while the yogurt cultures. The longer the yogurt cultures, the tangier the taste.
  6. After the 8 hours are up, enjoy your yogurt – or strain for a thicker yogurt. If you want it thicker, line a colander with 2 or 3 squares of cheesecloth. Place the colander on top of a metal bowl and pour the yogurt into the cheese-lined colander. Carefully place the bowl in the refrigerator for a couple hours. After trial and error, I believe 3 hours is the right length of time for this straining. You can check the thickness of your yogurt by stirring it. Whenever you think it is ready, scoop the yogurt out of the colander and put it in glass jars or storage containers.
  7. Enjoy your delicious yogurt…saving a half a cup for the starter in your next batch!
