The best sour cream replacements depend on what you're making
Sour cream works in a recipe because it brings three things: tang, fat, and moisture. The best replacement depends on which of those matters most for your dish. For baking, you need something that adds moisture and lift. For toppings and dips, you need tang and creaminess. For cooking, you need fat and acidity. No single substitute does all three equally well, so matching the replacement to the dish is what makes the difference.
The most common replacements are Greek yogurt, regular yogurt, buttermilk, cream cheese, and cottage cheese. Each one works better in some recipes than others. If you have more than one option in your kitchen, you can usually find something that works.
Key Takeaways
- Greek yogurt is the closest match for sour cream in most baked goods and can replace it one-to-one, though it is thinner and less tangy.
- Regular yogurt works for baking and toppings but may make batters thinner, so reduce other liquids slightly.
- Buttermilk replaces sour cream in recipes where you also have baking soda, because the acid-base reaction is what makes the recipe rise.
- Cottage cheese blended smooth works for dips and sauces but not for baking, because it does not hold together the same way.
- Cream cheese mixed with milk or water creates a tangy, creamy substitute for sour cream in almost any recipe.
Greek yogurt for baking and toppings
Greek yogurt is the closest substitute for sour cream in most recipes. It has more protein and less liquid than regular yogurt, which means it behaves more like sour cream in batters and doughs. You can replace sour cream with Greek yogurt in a one-to-one ratio in cakes, muffins, quick breads, and brownies.
The main difference is that Greek yogurt is less tangy than sour cream. If the recipe depends on that sharp flavor — like in a sour cream coffee cake or a baked potato topping — the result will taste milder. Greek yogurt is also slightly thinner, so if your batter seems too loose, you can add a tablespoon of flour or reduce the milk slightly. For toppings, dips, and sauces, Greek yogurt works straight from the container.
Regular yogurt when Greek yogurt is not available
Plain yogurt (not vanilla or flavored) works in baking, but it has more water than Greek yogurt, so you need to adjust. Replace sour cream with yogurt at a ratio of about 7/8 cup yogurt for every 1 cup of sour cream, or reduce other liquids in the recipe by 2 to 3 tablespoons. This keeps your batter from becoming too thin.
Regular yogurt works well in pancakes, waffles, muffins, and cakes. It will not change the flavor much, though the result may be slightly less tangy. For cold toppings like baked potatoes or tacos, you can use it straight, but it will be runnier than sour cream. If you want it thicker, strain it through cheesecloth for 30 minutes to an hour to remove some of the whey.
Buttermilk for recipes with baking soda
Buttermilk is a good replacement when your recipe calls for both sour cream and baking soda. The acid in buttermilk reacts with baking soda to create lift, which is the whole point of using sour cream in those recipes. Use buttermilk in a one-to-one ratio, but keep the baking soda amount the same.
Buttermilk is thinner than sour cream, so if the recipe does not have baking soda, reduce other liquids by about 1/4 cup per cup of sour cream called for. Buttermilk works well in pancakes, biscuits, cakes, and quick breads. It will not work as a topping because it is too thin and not creamy enough.
Cream cheese mixed with milk or water
Cream cheese is tangy and rich, but it is too thick to use straight. Mix it with milk or water to reach the right consistency. Start with 8 ounces of softened cream cheese and 1/4 cup of milk, then whisk until smooth. Add more milk if it is still too thick. This mixture can replace sour cream in a one-to-one ratio in almost any recipe.
This substitute works especially well in baking, dips, sauces, and toppings. The flavor will be slightly different — cream cheese is tangier and richer — but most people will not notice the change. If you want it tangier, add a tablespoon of lemon juice or vinegar. If you want it thinner for a sauce, add more milk.
Cottage cheese for dips and sauces
Cottage cheese can replace sour cream in dips, sauces, and toppings, but not in baking. Blend it smooth in a food processor or blender with a little milk or water until it reaches the thickness of sour cream. Start with 1 cup of cottage cheese and 2 tablespoons of milk, then add more milk as needed.
Blended cottage cheese works well for baked potato toppings, tacos, and cold dips. It will not work in cakes or muffins because the texture does not hold together the same way during baking. For a tangier flavor, add a tablespoon of lemon juice or vinegar to the blended mixture.
Milk and vinegar or lemon juice as a quick fix
If you have milk and either vinegar or lemon juice, you can make a sour cream substitute in minutes. Mix 1 cup of milk with 1 tablespoon of white vinegar or lemon juice and let it sit for 5 to 10 minutes. The milk will curdle slightly and thicken. This mixture is thinner than sour cream, so it works best in recipes where sour cream is mixed into a batter rather than folded in.
This substitute works in pancakes, muffins, cakes, and quick breads. It will not work as a topping because it is too thin. The flavor will be tangy but not as rich as sour cream. If you want it thicker, use less milk or let it sit longer before using.
Frequently Asked Questions
Can I use mayonnaise instead of sour cream?
Mayonnaise is mostly oil and eggs, so it does not have the tang or the same moisture content as sour cream. It can work in small amounts in dips or salad dressings, but it will change the flavor noticeably. For baking, it will make the texture greasy rather than light.
What if the recipe calls for sour cream and baking powder, not baking soda?
Baking powder already has acid in it, so you do not need the tang from sour cream for the rise. Any of the substitutes above will work — Greek yogurt, regular yogurt, cream cheese, or cottage cheese. You can use them in a one-to-one ratio without adjusting other ingredients.
Will the recipe taste different if I use a substitute?
It depends on the substitute and the recipe. Greek yogurt tastes very similar to sour cream. Regular yogurt and buttermilk are slightly less tangy. Cream cheese is tangier and richer. In most baked goods, the difference is small enough that most people will not notice. In recipes where sour cream is the main flavor — like a topping or a dip — the difference will be more obvious.
Can I use heavy cream instead of sour cream?
Heavy cream is rich but not tangy, so it will not work in recipes where the tang matters. It also does not have the same thickness. You could whip it and use it as a topping, but for baking or cooking, one of the other substitutes will work better.
How do I make sour cream thicker if my substitute is too runny?
Strain it through cheesecloth or a fine-mesh strainer for 30 minutes to an hour to remove liquid. You can also add a tablespoon of cornstarch mixed with a little cold water and heat it gently on the stove, stirring constantly, until it thickens. Let it cool before using.
