Learn how to make homemade yogurt with just milk and a yogurt starter culture. This simple step-by-step method shows how to culture yogurt at home using a yogurt maker, Instant Pot, slow cooker, or oven proof setting. Includes tips for choosing milk, starter cultures, and getting thick, creamy yogurt every time.
Warm the milk to 110°F if using ultra-pasteurized milk. If using regular pasteurized milk, heat to 160°F, then cool to 110°F.
64 oz whole milk (1 half gallon)
In a small bowl, mix the starter with a few tablespoons of the warm milk until smooth.
1 envelope yogurt starter cultures
Whisk the starter mixture back into the warm milk.
Pour the cultured milk into the jars of a yogurt maker.
Incubate for 8 to 12 hours, depending on how mild or tangy you want the yogurt.
Refrigerate for at least 4 hours before serving.
Save 3 tablespoons of yogurt as starter for your next batch.
Alternate Incubation MethodsInstant Pot: Use the yogurt setting and incubate for 8–12 hours.Slow cooker: Use the warm setting with jars raised off the bottom.Oven proof setting: Use only an oven proof setting around 110–120°F.
Notes
Alternate incubation options: Instant Pot, slow cooker, or an oven with a proof setting.
Milk choice: Whole milk makes thicker yogurt, but lower-fat free milk also works.
Starter: Use plain unsweetened yogurt with live cultures or a dehydrated yogurt starter.
Incubation time: Longer incubation makes tangier, firmer yogurt.
Save starter: Freeze small portions if needed so you always have some on hand.
