  • 1/2 gallon milk
  • 2 tablespoons prepared yogurt with cultures


  • Pour milk into inner pot of Instant Pot. Push yogurt button until the screen reads "boil." (Usually you will need to hit the yogurt button two times) This will take about an hour. 
  • Once the Instant Pot beebs that the boil cycle is complete, carefully remove the lid and test the temperature. It should be around 180 degrees. Let inner pot sit in instant pot for 5 minutes and then remove inner pot. 
  • Allow the milk to cool to 105-115 degrees. This will take an hour on the countertop or about 15 minutes if you place your inner pot into an ice bath. 
  • Gently skim off the "skin" on the yogurt and discard.  
  • Whisk in the prepared yogurt. 
  • Place inner pot (be sure to dry off well if you had in ice bath),put lid on and press yogurt button again and then adjust until screen reads 8:00. (The pressure should also read normal--if it reads less, hit adjust again until normal is lit up.)
  • Once yogurt beeps that it is complete, store in glass jars or a large plastic container in the fridge.
  • This is a great time to freeze some yogurt for future yogurt making. 


  • Instead of prepared yogurt as your starter, you can use a yogurt starter. Just follow directions to determine how much starter to add to 1/2 gallon milk (each brand is a bit different.)
  • You can use any percentage of fat to make homemade yogurt.
  • To make Greek yogurt, strain the yogurt in a strainer lined with cheesecloth overnight in the fridge (be sure to place over large mixing bowl while draining.)
  • Homemade yogurt should last for about 10-14 days. 
  • If sweetening yogurt, I have found it is best to add in sweeteners/vanilla after yogurt has set up in fridge for at least 8 hours, or after straining.
