Homemade Plain Whole Milk Yogurt in the Instant Pot

When it has finished, press Cancel until the display reads “Off.” Use oven mitts to remove the inner pot (be careful—it’s hot!) and place it on a trivet or other heat-resistant surface.

Allow the milk to cool, stirring occasionally, until the temperature drops to 110°F as measured on an instant-read thermometer, about 1 hour. (If you do not have a thermometer, use a small spoon to drip a few drops of the milk on the inside of your wrist.

It should feel just above body temperature—very slightly warm but not hot.

Err on the side of too cool, since too much heat will kill the necessary bacteria in the yogurt in the next step.).

Add the yogurt to the inner pot and stir thoroughly.

Return the inner pot to the Instant Pot.

Press the Yogurt button and use the Yogurt or Adjust button to select the middle temperature (“Normal”).

Use the − or + button to set the time to 8 hours.

Close and lock the lid.

Set the valve to Sealing.

When the cycle ends, press Cancel and remove the lid.

Stir the yogurt and then use a large spoon to scoop it into a container with a lid or single-serving containers with lids.

Place the covered container(s) in the refrigerator to cool, about 3 hours, before serving.

Whole Milk Yogurt will keep, in an airtight container in the refrigerator, for up to 2 weeks.
