How they compare, per 100 g
Most substitute guides tell you what works and stop there. If you are choosing partly on macros, here are the numbers side by side.
Greek yogurt and blended cottage cheese both roughly quadruple the protein, which is the whole argument of this page. Watch the other direction too: cream cheese, crème fraîche and coconut cream are all richer than the sour cream they replace, so reaching for one of those costs you fat rather than saving any.
| Per 100 g | kcal | Protein | Carbs | Fat |

| Sour cream | 198 | 2.4 g | 4.6 g | 19 g |
| Plain Greek yogurt | 59 | 10 g | 3.6 g | 0.4 g |
| Plain regular yogurt | 61 | 3.5 g | 4.7 g | 3.3 g |

Every option, and when to use it
ReciPop picks one swap because it is optimising for your macro goal. Cooking is broader than that, so here is the full list including the ones the app does not reach for.
| Use | How much | Best for |
|---|---|---|
| Plain Greek yogurt | 1:1 | dips, toppings, baking, and anything cold Watch out: split it into a hot sauce and it can curdle, so take the pan off the heat first |
| Plain regular yogurt | 1:1, drained if you can | dressings, marinades, and baking Watch out: thinner than sour cream, so batters loosen slightly |
| Cream cheese | 1:1, softened and loosened with a splash of milk | cheesecake, frosting, and thick dips |
| Creme fraiche | 1:1 | hot sauces and pan sauces, because it does not split Watch out: higher in fat than sour cream, so it moves the macros the wrong way |
| Buttermilk | 3/4 cup per 1 cup, and cut other liquid | cakes, pancakes, and soda bread Watch out: pourable, so useless as a topping |
| Cottage cheese, blended | 1:1, blended smooth with a squeeze of lemon | high-protein dips and baking Watch out: must be blended properly or it stays grainy |
| Coconut cream | 1:1, chilled and the thick part spooned off | dairy-free curries and soups Watch out: tastes of coconut, so it does not disappear into everything |
If you are shopping in the UK, soured cream is the same thing under a different name, and everything below applies to it unchanged.
Which one for which job
The right substitute depends less on flavour than on heat and thickness. That is the whole decision, and it takes about ten seconds once you know it.
For baking
Plain yogurt, Greek yogurt, or buttermilk. Sour cream does two things in a batter: it adds fat for tenderness and acid to react with raising agents. Yogurt covers both. Buttermilk covers the acid well but is much thinner, so reduce the other liquid by roughly a quarter cup per cup used.
For tacos, nachos, and anything you spoon on top
Greek yogurt, straight swap. It is thick enough to hold its shape on a taco and tangy enough that most people do not notice. This is also where the protein difference is worth the most, because a topping is usually a decent dollop.
For pasta and hot sauces
Creme fraiche. This is the one case where Greek yogurt is the wrong answer: yogurt splits when it hits a simmering pan, and a split sauce cannot be rescued. Creme fraiche has enough fat to stay smooth. If you only have yogurt, take the pan off the heat, wait a minute, then stir it through and do not let it boil again.
For soup
Same rule as pasta. Stir it in off the heat, or use creme fraiche. A spoonful swirled on top at the table avoids the problem entirely.
For cheesecake
Cream cheese or Greek yogurt. Cheesecake is forgiving here because it bakes low and slow, so the splitting risk is small. Greek yogurt makes a slightly lighter, tangier cheesecake.
What actually changes when you swap
Sour cream is roughly 20 percent fat and low in protein. Greek yogurt inverts that. Swapping one for the other in a dish serving four is worth about 6 g more protein and 6 g less fat per serving, and around 45 fewer calories.
Those are estimates, calculated from typical ingredient values rather than measured in a lab, and they move with the brand you buy. A zero-fat Greek yogurt swings further than a 5 percent one. The direction is reliable even when the exact number is not.
Two of our recipes carry this swap already, with the numbers worked out per serving: the ground turkey chili, where a spoonful goes on top, and the high-protein breakfast burritos, where it goes inside and the wrap swap stacks on top of it.
Where the swap matters most
Mashed potatoes are the clearest case on this page. The sour cream goes in off the heat so nothing splits, and the tang is the whole reason it is there, which means Greek yogurt does the same job for roughly 2 g more protein and 5 g less fat a serving. The method, and the two things that actually ruin mash, are on lighter mashed potatoes.
Crème fraîche, Greek yogurt and sour cream, which is which
Three cultured dairy products that look alike in the tub and behave completely differently in the pan. Worth ten lines, because swapping one for another is the most common way this goes wrong.
Greek yogurt is the high-protein, low-fat one, and it is the swap this page recommends. It also splits the moment it boils, which is why every section here tells you to stir it in off the heat.
Sour cream sits in the middle on fat and will also split if you let it boil, though it is a little more forgiving than yogurt.
Crème fraîche is the rich, stable one. It has the most fat of the three and it does not split in a simmering pan, which makes it the safest in a hot sauce and the worst for your macros.
So if you are asking whether you can use crème fraîche instead of Greek yogurt, the answer is yes and it will work better in heat, but you are going the wrong way on both numbers this page cares about. You gain reliability and lose protein and lose the fat saving. Going the other direction, yogurt for crème fraîche, is a genuine macro win as long as the pan comes off the heat first.

Soured cream and yoghurt, if you are shopping in Britain
Two of the words on this page change on a UK label, and one of those changes matters more than a spelling.
Soured cream is sour cream. Yoghurt is yogurt. Nothing about the swap moves.
Greek yoghurt is the one to read carefully. In Britain the shelf carries both Greek yoghurt and Greek style yoghurt, and they are not the same product. Greek yoghurt is strained, which is where the protein comes from and the reason this page recommends it at all. Greek style is thickened to feel similar, often with cream or added starch, and it has not been strained. Pick up the wrong tub and you get the texture you wanted while the protein gain that motivated the swap quietly does not happen, and the fat can go up rather than down.
The label settles it in about five seconds. Turn the pot over and compare the protein per 100 g against the plain yoghurt next to it. If it is not meaningfully higher, it was not strained, whatever the front of the tub says.
The one that is not really a substitute
Mayonnaise gets recommended a lot and it is worth being clear: it works texturally in cold dips and nowhere else. It is higher in fat than sour cream, has almost no protein, and tastes distinctly of mayonnaise. If the goal is a lighter or higher-protein dish, it moves you backwards.
Common questions
Plain Greek yogurt, used 1:1. It is the closest match on thickness and tang, works hot or cold if you are careful with heat, and adds protein rather than fat. If you are baking, plain yogurt or buttermilk both work, and buttermilk means cutting other liquid slightly.
One cup of plain Greek yogurt, one cup of creme fraiche, or one cup of softened cream cheese loosened with a tablespoon or two of milk. For baking specifically, three quarters of a cup of buttermilk works if you reduce the other liquid in the recipe by about a quarter cup.
Yes. Stir one teaspoon of lemon juice or white vinegar into one cup of heavy cream and leave it at room temperature for about 30 minutes until it thickens. It behaves like sour cream in cooking, though it is higher in fat than the shop-bought version.
Blended cottage cheese, then Greek yogurt. Both roughly double the protein of the same weight of sour cream while cutting fat. This is the swap ReciPop applies when your goal is more protein, and it shows the estimated change per serving before you commit to it.
It can. Yogurt splits when it hits high heat because it is lower in fat than sour cream. Take the pan off the heat, let it cool for a minute, then stir the yogurt through. If the dish has to simmer afterwards, use creme fraiche instead, which holds together.
