You are elbow deep in a batch of chicken enchiladas for a dinner party and the sour cream tub in the fridge turns out to be empty. Maybe you are baking a cheesecake and the recipe calls for a cup you simply do not have. Or you just want a lighter topping for tonight’s tacos. Sour cream is one of the easier dairy staples to swap out. It has two main jobs: adding tangy richness to sauces and baked goods, and serving as a thick, cool topping. Both come down to fat and acidity, and you can cover either one with ingredients already sitting in most kitchens.
What Can You Use Instead of Sour Cream?
The Short Answer: Greek yogurt, crème fraîche, buttermilk, plain yogurt, blended cottage cheese, ricotta, and kefir all work well. So do cream cheese, mayonnaise, cashew cream, and coconut cream or coconut yogurt. Most swap in at close to a 1:1 ratio, though several curdle if they hit direct heat. The right choice depends on what the sour cream needs to do. Does it need to survive a simmer, blend into a baked good, or simply get dolloped on top of something?

Key Takeaways
Sour cream serves two distinct functions in cooking: adding tangy richness to sauces, dips, and baked goods, and acting as a thick, cool garnish that holds its shape when dolloped. The best substitute depends on which job you need.
For hot dishes, crème fraîche is the safest swap since its higher fat content lets it simmer without breaking. Buttermilk and plain yogurt both curdle easily under direct heat, so stir them in at the very end or off the heat entirely.
For baking, buttermilk and Greek yogurt both bring the acidity that reacts with baking soda, giving cakes and quick breads their rise and tender crumb.
For dolloping on tacos, baked potatoes, or chili, Greek yogurt, cashew cream, and coconut cream all hold their shape well. Plain yogurt, buttermilk, and kefir are all too thin for this job.
For a dairy-free or vegan substitute, cashew cream and coconut cream or coconut yogurt are the two most reliable options. A splash of lemon juice or vinegar helps either one mimic sour cream’s characteristic tang.
