1. Cottage Cheese
Cottage cheese can make a healthier and lower-calorie substitute for sour cream in many recipes. Though different in flavor, cottage cheese mimics the texture and creaminess of sour cream remarkably well. The neutral flavor of cottage cheese also allows the other ingredients to shine.
Simply replace sour cream with an equal amount of cottage cheese that has been pureed or processed until smooth. Use it as a topping, in dips, in baked goods, or anywhere else you'd use sour cream. Give it a try in your next recipe that calls for sour cream.
