Plain Greek yogurt is the best sour cream substitute, working one to one in both cooking and baking with a similar tang and thickness. Buttermilk, creme fraiche and blended cottage cheese also work. For baking, these keep cakes moist and add the acidity that helps them rise.
Best swap: plain Greek yogurt, 1 to 1. Also buttermilk, creme fraiche, or blended cottage cheese.
Sour Cream Substitutes
- Plain Greek yogurt: the closest match, swapped one to one.
- Creme fraiche: richer and less tangy, great in sauces.
- Buttermilk: thinner, best where a little extra liquid is fine.
- Cottage cheese: blend until smooth for a similar body.
Cooking vs Baking
In baking, sour cream adds moisture and acidity, so yogurt or buttermilk substitute well and even help the rise. In hot sauces, stir dairy substitutes in off the heat to prevent curdling, and avoid boiling. For more swaps, see the heavy cream substitute guide. Good measuring cups keep proportions right.
