Learn how to make thick, creamy Greek yogurt with just two ingredients and no special equipment. Most of the time is hands-off as the yogurt cultures, chills, and strains until it is as thick as you like.
1/4cupplain yogurt with live active cultures, at room temperature
Instructions
Heat the milk. Rinse the inside of a heavy 3- to 4-quart pot with a lid with cold water to help prevent scorching. Add the milk and place the pot over medium heat. Bring to a gentle simmer, stirring occasionally, about 15 minutes. When bubbles begin forming around the edges, check the temperature. Once the milk reaches 190°F to 200°F, remove the pot from the heat.
Cool the milk. Let the milk cool in the pot, stirring occasionally, until it reaches 105°F to 115°F. If it drops below that range, gently reheat it. Place the room-temperature yogurt in a small heatproof bowl.
Temper the starter. Slowly stir 1/2 cup of the warm milk into the yogurt to thin it. Slowly stir this mixture back into the pot, distributing the cultures throughout the milk.
Incubate the yogurt. Cover the pot and place it in a warm spot. Leave it undisturbed for at least 6 and up to 10 hours. The exact time will depend on the temperature of the room. It is ready to chill when it looks somewhat set rather than liquid.
Chill without disturbing. Transfer the covered pot to the refrigerator and chill for at least 6 hours and up to 2 days. The yogurt will continue to thicken and develop its tangy flavor.
Strain the yogurt. Set a fine-mesh strainer or colander over a large bowl and line it with finely woven cheesecloth. Spoon in the chilled yogurt and return it to the refrigerator. Let it drain for 2 to 8 hours, depending on how thick you like your Greek yogurt.
Store and enjoy. Transfer the strained yogurt to airtight containers. Cover and refrigerate for up to 2 weeks.

Why heat the milk? Heating pasteurized milk to 190°F to 200°F changes its proteins, helping the finished yogurt set with a thicker, smoother texture.
To cool the milk faster: Place the pot in an ice bath. Remove it when the milk reaches 112°F.
To make regular yogurt: Skip the straining step. This recipe will yield about 8 cups of unstrained yogurt. Pour off any whey that separates or stir it back in.
To save starter: Reserve 1/4 cup of the finished yogurt in an airtight container. Refrigerate and use it within one week.
To store: Keep the finished Greek yogurt covered and refrigerated for up to 2 weeks.
