Plain yogurt is the closest substitute for most recipes
Plain yogurt works as a one-to-one replacement for sour cream in nearly every dish. The texture and tang are similar enough that most people won't notice the difference. Use full-fat yogurt if you have it—it's closer to sour cream's richness than low-fat versions.
The main difference is that yogurt is slightly thinner. If your recipe needs sour cream for thickness (like in a baked good or topping), strain the yogurt through cheesecloth for a few hours to remove whey and thicken it. If you're using it in a sauce or soup where consistency matters less, you can use it straight from the container.
Yogurt works in baking, dips, toppings, marinades, and sauces. It's especially good in recipes where the sour tang is important—like in baked goods where sour cream reacts with baking soda, or in dips where you want that sharp flavor.
Key Takeaways
- Plain yogurt is a direct replacement in most recipes and requires no adjustment to the amount you use.
- Greek yogurt is thicker than regular yogurt and closer to sour cream's texture, though it has a stronger tang.
- Cottage cheese blended smooth works in baking and sauces but changes the flavor slightly.
- Buttermilk mixed with butter or oil creates a substitute when you need both the liquid and fat properties of sour cream.
- Cream cheese thinned with milk works in baking but produces a denser, richer result than sour cream would.
Greek yogurt for a thicker texture
Greek yogurt is already strained, so it's thicker than regular yogurt and closer to sour cream's consistency without extra work. Use it one-to-one in most recipes. The trade-off is that Greek yogurt has a stronger, more sour taste than regular yogurt, so it can overpower delicate dishes.
Greek yogurt works best in recipes where a pronounced tang won't hurt—dips, marinades, baked goods, and toppings. It's less ideal in recipes where you want mild flavor, like in a creamy sauce for chicken or vegetables. If you use it in baking, the extra protein can make baked goods slightly denser, but the difference is usually small enough to ignore.
Cottage cheese blended for baking and sauces
Cottage cheese can replace sour cream, but you need to blend it first. Run it through a food processor or blender until it's smooth—this takes about two minutes. Once blended, use it one-to-one in recipes.
Blended cottage cheese works well in baking, casseroles, and creamy sauces. The flavor is milder and less tangy than sour cream, so baked goods won't have quite the same sharpness. In savory dishes like stroganoff or casseroles, the difference is barely noticeable. Cottage cheese is also higher in protein, which can make baked goods slightly denser if you use a lot of it.
The main drawback is the texture before blending—if you don't blend it smooth, you'll have lumps in your final dish. It's worth the extra step if you have cottage cheese on hand and need a substitute.
Buttermilk and butter for baking
Sour cream does two things in baking: it adds liquid and it adds fat. Buttermilk alone replaces only the liquid part. To replace sour cream fully, mix buttermilk with melted butter or oil.
For every cup of sour cream, use one cup of buttermilk plus two tablespoons of melted butter or neutral oil. Stir them together and use the mixture one-to-one in place of sour cream. This works in cakes, quick breads, biscuits, and pancakes.
The flavor will be slightly different—buttermilk is tangier and less rich than sour cream—but the texture of the finished baked good will be close. This substitute is especially useful if you have buttermilk in the fridge but no sour cream.
Cream cheese thinned with milk
Cream cheese is richer and denser than sour cream, so you need to thin it. Mix one part cream cheese with one part milk (or water) and stir until smooth. Use this mixture one-to-one in place of sour cream.
This substitute works in baking, dips, and sauces. The result will be richer and slightly less tangy than if you'd used sour cream. Baked goods made with this substitute tend to be denser and more tender. Dips and sauces will be creamier and less sharp-tasting.
Cream cheese is best when you want richness and don't mind a milder flavor. It's less ideal if the recipe relies on sour cream's tang to balance other flavors.
Lemon juice or vinegar with heavy cream
You can make a quick sour cream substitute by mixing heavy cream with lemon juice or vinegar. The acid curdles the cream slightly and adds tang. Mix one cup of heavy cream with one tablespoon of lemon juice or white vinegar, stir, and let it sit for five to ten minutes until it thickens slightly.
This substitute is closest to real sour cream in both flavor and texture. It works in any recipe—baking, toppings, sauces, dips. The main drawback is that you need heavy cream on hand, which is less common in many kitchens than yogurt or buttermilk.
The substitute will be slightly thinner than store-bought sour cream, especially if you use lemon juice instead of vinegar. If thickness matters, let it sit a bit longer before using it.
Mascarpone thinned for rich dishes
Mascarpone is an Italian cream cheese that's richer and less tangy than sour cream. Thin it with milk the same way you would cream cheese—one part mascarpone to one part milk. Use it one-to-one in place of sour cream.
Mascarpone works best in recipes where richness is welcome and tang is not—creamy pasta sauces, desserts, and toppings. It's less ideal in recipes where sour cream's sharpness is important, like in baking where it reacts with baking soda, or in dips where you want that distinctive sour flavor.
Frequently Asked Questions
Can I use milk and vinegar instead of sour cream?
Milk alone won't work—it lacks the fat and tang. But milk mixed with vinegar or lemon juice can work if you let it sit. Mix one cup of milk with one tablespoon of vinegar, let it sit for five to ten minutes until it curdles slightly, then use it. The result is thinner than sour cream and less rich, but it works in baking and sauces.
What's the best substitute for sour cream in baking?
Plain yogurt or Greek yogurt is usually best because the texture and tang are closest to sour cream. If you don't have yogurt, buttermilk mixed with butter works well. Avoid cream cheese or mascarpone in baking unless you want a denser, richer result—they don't react with baking soda the way sour cream does.
Can I use regular milk as a sour cream substitute?
No. Milk is too thin and lacks the tang and fat that sour cream provides. You need to add acid (lemon juice or vinegar) and fat (butter or oil) to make milk work as a substitute. Plain milk will change the texture and flavor of your recipe too much.
Is Greek yogurt thicker than regular yogurt?
Yes. Greek yogurt is strained to remove whey, so it's much thicker and closer to sour cream's consistency. Regular yogurt is thinner and may need to be strained if you need a thick substitute. Greek yogurt also has a stronger, more sour taste.
What if I need sour cream for a topping?
Plain yogurt, Greek yogurt, or heavy cream mixed with lemon juice all work as toppings. Greek yogurt is thickest and closest in texture. If you want something richer, use mascarpone or cream cheese thinned with a little milk. Cottage cheese blended smooth also works but has a different texture.
