You can use sour cream instead of yogurt at a ratio of 1:1 — one cup of sour cream for one cup of yogurt. This is the reverse of the yogurt-for-sour-cream swap, and it is just as easy: sour cream is a little richer, a little milder and a little less tangy than yogurt, so everything you make with it will taste rounder and more luxurious. In a dip, a marinade or a topping, the swap is nearly invisible. In baking, it is just as good: sour cream's acidity gives the same lift with baking soda. This is the swap for the cook who has sour cream and no yogurt, and it works in almost every recipe that calls for yogurt — with the bonus that the result is usually richer.

The ratio, in a table

The ratio is 1:1. Cheeses swap 1:1 by weight; saltiness and melt are what change. The table below converts the amounts you are most likely to meet.

Yogurt called for Sour cream to use Notes
1 tablespoon 1 tablespoon
1/4 cup 1/4 cup
1/3 cup 1/3 cup
1/2 cup 1/2 cup
2/3 cup 2/3 cup
3/4 cup 3/4 cup

1 1/2 cups 1 1/2 cups
2 cups 2 cups

By weight, one cup of yogurt weighs about 245 grams (USDA, spooned and levelled), and one cup of sour cream weighs about 230 grams (USDA, poured). The two are close enough that a cup-for-cup swap works by volume, and the weights are useful when you want to be precise. All cup weights are approximate — densities vary by brand, by how the ingredient is packed, and by moisture — so verify with a kitchen scale where weighing matters, especially in baking.

Worked examples

A marinade that makes chicken juicier

A chicken marinade calls for 1 cup of yogurt with garlic, lemon and spices. Replace it with 1 cup of sour cream, and stir in the same garlic, lemon and spices. The sour cream's acidity tenderises the chicken just as yogurt's does, and its higher fat content coats the chicken more thickly, so the marinade clings better and the chicken stays juicier on the grill. Marinate for the same time — at least an hour, or overnight — and cook as usual. The chicken will be a touch richer and less tangy than the yogurt version, which suits a grilled chicken beautifully.

A creamy salad dressing that is rounder and richer

A salad dressing recipe asks for 1 cup of yogurt with herbs, lemon and garlic. Use 1 cup of sour cream instead, and whisk in the same herbs, lemon and garlic. The dressing will be thicker, richer and milder than the yogurt version, with a rounder flavour that coats salad leaves beautifully. Thin it with a tablespoon of milk or water if it is too thick to pour, and taste for salt — the milder flavour can make the dressing taste under-seasoned. Serve over a green salad or a grain bowl. The dressing is not just a substitute; it is a richer, more indulgent version of the same idea.

A yogurt cake that becomes a sour cream cake

A lemon yogurt cake calls for 1 cup of yogurt in the batter. Replace it with 1 cup of sour cream, stirred in at the same stage. The cake will be denser, richer and more tender than the yogurt version, with a finer crumb, and the lemon flavour will be rounder and less sharp. The sour cream's acidity gives the same lift with baking soda, so the cake rises just as well. Bake at the same temperature and check five minutes early. The result is a classic sour cream cake — a well-known style of cake in its own right — and the lemon still shines through.

What changes in the result

Two things change when you use sour cream instead of yogurt, and both are small. First, the flavour: sour cream is milder, rounder and richer-tasting than yogurt, which is sharper and fresher. In a marinade or a dressing, the difference is a matter of taste — the sour cream version is more indulgent, the yogurt version is brighter. Second, the richness: sour cream has about 20 percent fat against yogurt's 3 to 10 percent, so the result is noticeably richer and heavier. The texture is very close: both are thick and spoonable, so dips hold their shape and batters behave the same way. The chemistry is identical: both are acidic, so both react with baking soda to give lift. The stability is the same too: both curdle if you boil them, so both must be added off the heat in a sauce.

When not to substitute

Do not swap a hard aged cheese for a soft fresh one in a sauce — it will not melt the same way. Do not use sour cream instead of yogurt in a dish where the yogurt's sharp tang is the point — a raita, a tzatziki, or a marinade where the brightness matters. In those dishes the sour cream will taste too rich and too mild, and the dish will lose its edge. Do not use it in a sauce that needs to be boiled — both will curdle, so the swap does not fix that problem. And do not use it if you specifically want a light result: sour cream has far more fat than yogurt, so the swap makes a dish heavier, which is the opposite of what you want in a light summer dressing or a breakfast bowl.

Practical guidance

Use full-fat sour cream for the closest result, and stir it before measuring — it can separate slightly in the tub. In baking, add it at the same stage the yogurt would go in, and do not overmix. In a dressing, thin it with a tablespoon of milk or water if it is too thick to pour. Taste for acidity at the end: the dish will be milder than the yogurt version, and you may want a squeeze of lemon to replace some of the lost brightness. In a sauce, add the sour cream off the heat and never boil it afterwards. All amounts here are approximate, and the 1:1 ratio is by volume; a cup of sour cream weighs about 230 grams, so verify with a kitchen scale where weighing matters.

Frequently asked questions

How much sour cream do I use instead of yogurt?

Use the same amount: 1 cup of sour cream for 1 cup of yogurt. The result is richer and milder than the yogurt version, so it works well in dips, marinades, dressings and baking.

Can I use sour cream instead of yogurt in a marinade?

Yes. Sour cream's acidity tenderises meat just like yogurt's does, and its higher fat content helps the marinade cling to the chicken. Marinate for the same time and cook as usual.

Does sour cream taste the same as yogurt?

Almost. Sour cream is milder, rounder and richer, while yogurt is sharper and fresher. In a dip or a cake the difference is small, but in a raita or a tzatziki — where the tang is the point — the difference matters.

Can I use sour cream instead of yogurt in baking?

Yes. Sour cream is acidic just like yogurt, so it reacts with baking soda to give the same lift, and it keeps cakes just as moist. The result is usually denser and richer than the yogurt version.

Is sour cream healthier than yogurt?

No. Sour cream has about 20 percent fat, while yogurt has 3 to 10 percent, so sour cream is richer and higher in calories. The swap is an upgrade in richness, not in health — use it when you want a more indulgent result.
