Set up large bowl with strainer inside. Set coffee filter or cheesecloth in the strainer.
Spoon yogurt into the filter and cover with a lid or plastic wrap.
Filter in the refrigerator for 24-72 hours, removing whey for discard or other use, and changing coffee filter halfway through.
Remove the thickened creamy yogurt cheese from the filter and store in an airtight container. Enjoy within 1-2 weeks.
Full batch of 5 cups yogurt makes about 2 cups of yogurt cheese, and about 3 cups of whey.
