Add the milk to the pot of the Ninja Foodi and lock the pressure lid. Set the valve to "vent".
Select the yogurt function and the time to 8 hours, then press the start button.
The Ninja Foodi will begin to boil the milk. After this is done, it will move to a cool down period. This can take several hours to cool down.
Once the milk is cooled back down, the Foodi will display "add & stir". This is where you will add your yogurt starter. Stir it in well with a silicone spatula.
Replace the pressure lid with the valve to vent and press the start button again. It will begin the incubation period for 8 hours.
Once this is done, transfer to individual glass jars, Mason jars, or glass bowl with a lid. Allow to rest in the refrigerator for about 8 hours or overnight.
Notes
You can make the yogurt thicker by choosing a specific starter and straining it overnight in the refrigerator with cheesecloth. If making another batch from your initial first batch, take about 3 tablespoons of your yogurt during the “stir & add” process.
