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.
Understanding What Sour Cream Actually Does
Before picking a substitute, it helps to know which of the two jobs your sour cream is doing in the recipe.
🔬 Two Jobs, Two Different Substitutes
In cooking and baking, sour cream adds acidity and fat to sauces, dips, marinades, and batters. That acidity reacts with baking soda to help cakes and quick breads rise, and it tenderizes gluten so baked goods come out softer. Under FDA rules, sour cream must contain at least 18 percent milkfat, and most commercial tubs sit close to that minimum. Crème fraîche typically runs higher, around 30 percent fat or more, which is why it holds together far better under heat than thinner options like buttermilk or plain yogurt.As a topping, sour cream needs to stay thick enough to sit on a taco, a baked potato, or a bowl of chili without running off or weeping liquid. This job calls for something with real body. Thin swaps like buttermilk work fine stirred into a sauce. But they turn into a puddle the moment you try to dollop them on top of anything. A milk and vinegar substitute for buttermilk, for example, handles baking well but has no place as a garnish.
The Best Sour Cream Substitutes
1. Greek Yogurt (Best All-Purpose Substitute)
Full-fat Greek yogurt is the closest match to sour cream in both tang and thickness, which makes it the most dependable all-purpose swap. Use it at a 1:1 ratio in dips, dressings, baked goods, and as a topping. Stir it in off the heat, or temper it first with a spoonful of the hot liquid. Do this if the recipe involves any cooking, since yogurt can still separate in a hard boil. Its thick texture also holds its shape well when dolloped, so it works as a topping just as easily as an ingredient.
2. Crème Fraîche (Best for Hot Sauces and Soups)
Crème fraîche is essentially French sour cream made from cream instead of milk, which gives it a higher fat content, typically 30 percent or more, and a milder tang. That extra fat means it can simmer directly in a hot sauce or soup without breaking, making it the safest substitute for anything that needs to cook on the stove. Swap it in at a 1:1 ratio. It also works beautifully stirred into mashed potatoes or spooned over roasted vegetables for a richer finish than sour cream alone provides.
3. Buttermilk (Best for Baking)
Buttermilk brings the same tang and acidity that makes sour cream useful in cakes, biscuits, and quick breads, though it is much thinner. Use 3/4 cup of buttermilk for every 1 cup of sour cream the recipe calls for, and consider cutting back slightly on other liquids to compensate for the added moisture. Save buttermilk for baking or for stirring into a dressing, since it curdles easily under direct heat. If a hot dish needs it, stir it in at the very end, off the burner, as more of a finishing touch than a cooking ingredient.
Ratio: 3/4 cup buttermilk per 1 cup sour cream
Note: Much thinner than sour cream. Curdles easily under direct heat, so add it last.
4. Plain Yogurt (Best Lighter Substitute)
Plain yogurt makes a lighter, slightly tangier stand-in for sour cream and works especially well in cold applications like dips and dressings. Swap it in at a 1:1 ratio, and strain it through a cheesecloth or coffee filter for an hour if the recipe needs something thicker for dolloping. Like buttermilk, plain yogurt curdles if it hits a hard boil. Keep it out of anything that needs to simmer for long. Or temper it first, the same way you would with Greek yogurt.
5. Cottage Cheese, Blended (Best High-Protein Substitute)
Blended cottage cheese brings significantly more protein than sour cream at a fraction of the calories, once you smooth out its characteristic curds. Combine 1 cup of small curd cottage cheese with 1/4 cup of milk and 2 teaspoons of lemon juice. Then blend in a food processor or with an immersion blender until completely smooth. Use the result at a 1:1 ratio. This swap works especially well in baked goods and blended soups, where its texture disappears entirely into the dish.
6. Cream Cheese (Best for Thick Dips and Baking)
Softened cream cheese thinned with a splash of milk makes a rich, thick substitute for sour cream in dips and baked goods. Whisk 1 cup of softened cream cheese with 2 to 3 tablespoons of milk and a teaspoon of lemon juice for extra tang, then use the mixture at a 1:1 ratio. It holds up well in baked dishes and spreads, though straight cream cheese without thinning is too dense to dollop or drizzle the way sour cream does.
7. Mayonnaise (Best for Cold Dips and Dressings)
Mayonnaise is an unexpected but genuinely useful stand-in for sour cream in cold dishes like dips, dressings, and creamy salads. Choose a light-colored, mild-flavored mayonnaise so it does not overpower the dish, and use it at a 1:1 ratio. A squeeze of lemon juice helps mimic sour cream’s tang, since mayonnaise on its own is much milder. This swap is strictly for cold applications: mayonnaise breaks and turns oily under heat, so keep it out of anything that needs to cook.
8. Cashew Cream (Best Vegan Substitute)
Cashew cream is a reliable dairy-free option that many cooks reach for specifically because raw cashews carry a natural, faint tang of their own. Soak 1 cup of raw cashews in hot water for about 30 minutes, then drain. Blend with 3/4 cup of fresh water and a tablespoon of lemon juice or vinegar until completely smooth. Use the result at a 1:1 ratio in sauces, dips, and dolloped toppings. It holds a nicely thick, spoonable texture once chilled, making it one of the better vegan options for garnishing tacos or chili.
✅ Best for: Vegan tacos, dips, sauces, chili toppings.
Ratio: 1:1
Note: Blend with lemon juice or vinegar for tang. Vegan and dairy-free.
9. Coconut Cream or Coconut Yogurt (Best Dairy-Free Topping)
Chilled coconut cream, scooped from the solid layer at the top of a refrigerated can, makes a thick, dairy-free topping. Plain coconut yogurt works the same way for anything you would normally finish with sour cream. Whisk in a squeeze of lime or lemon juice to add back the tang that plain coconut cream lacks on its own. Use either option at a 1:1 ratio. The main tradeoff is a mild coconut flavor, which works well on tacos and curries but is more noticeable in a plain baked potato.
10. Ricotta (Best Mild, Cheesy Substitute)
Ricotta brings a similar thickness and mild flavor to sour cream, though it lacks the tang since it is not fermented the same way. Swap it in at a 1:1 ratio, and whisk in a teaspoon of lemon juice or vinegar per cup to build back some of that missing sourness. Choose whole-milk ricotta rather than part-skim for the richest result. Its fine, slightly grainy texture melts smoothly into sauces and batters, though it is not the best choice for dolloping straight onto a taco or baked potato.
Ratio: 1:1, plus a teaspoon of lemon juice or vinegar per cup for tang
Note: Use whole-milk ricotta for the richest result. Add acid to build back the missing tang.
11. Kefir (Best Thin, Drinkable Substitute)
Kefir is a fermented, drinkable dairy product with a tang similar to sour cream, sitting somewhere between yogurt and buttermilk in texture. Use it at a 1:1 ratio in soups, stews, and dressings, or cut the amount in half when a dip needs more body than kefir alone can provide. Choose plain, unsweetened kefir for the closest flavor match. Its thin, pourable consistency makes it a poor fit for dolloping, so save it for dishes where it can blend into a liquid rather than sit on top of one.
✅ Best for: Soups, stews, salad dressings, smoothies.
Ratio: 1:1 in soups and dressings, or half the amount in thick dips
Note: Choose plain, unsweetened kefir. Too thin for dolloping.

Frequently Asked Questions
What can I use instead of sour cream in baking?
Buttermilk and Greek yogurt are the two best substitutes for sour cream in baking. Buttermilk swaps in at 3/4 cup per 1 cup of sour cream and brings the acidity that helps cakes and quick breads rise. Greek yogurt swaps in at a 1:1 ratio and adds a similar tang with a closer thickness to the original. Blended cottage cheese also works well in cakes and quick breads once it is fully smooth.
What can I use instead of sour cream in a dip?
Greek yogurt, cream cheese thinned with milk, and mayonnaise all work well in dips. Greek yogurt comes closest to the original texture and tang. Thinned cream cheese makes a thicker, richer dip. Mayonnaise works especially well in cold dips like a classic French onion dip, though a squeeze of lemon juice helps balance its milder flavor against sour cream’s natural tang.
Can I use yogurt instead of sour cream?
Yes. Full-fat Greek yogurt is the closest match and swaps in at a 1:1 ratio in nearly any recipe. Plain yogurt also works but is thinner and slightly tangier, so straining it through a cheesecloth for an hour helps it hold up better as a topping. Both curdle if they hit a hard boil, so stir them in off the heat or temper them first with a spoonful of the hot liquid.
Can I use mayonnaise instead of sour cream?
Yes, but only in cold applications. Mayonnaise works well in dips, dressings, and creamy salads at a 1:1 ratio, especially with a squeeze of lemon juice added for tang. It is not a good substitute for hot dishes, since it breaks and turns oily under direct heat.
What is the difference between sour cream and crème fraîche?
Sour cream comes from milk cultured with bacteria, while crème fraîche comes from cream soured the same way. That process gives crème fraîche a noticeably higher fat content, typically 30 percent or more. Sour cream’s FDA minimum, by comparison, is just 18 percent. That extra fat makes crème fraîche milder in flavor, thicker in texture, and far more stable under heat, so it rarely curdles the way sour cream can in a simmering sauce.
What is the difference between sour cream and Greek yogurt?
Cultured cream forms the base of sour cream, which under FDA rules must contain at least 18 percent milkfat, giving it a rich, mild tang. Straining cultured milk produces Greek yogurt instead, generally lower in fat unless you buy the full-fat version, with a sharper, more pronounced tang. In most recipes the two swap for each other at a 1:1 ratio with only a small difference in richness and acidity.
What can I use instead of sour cream for tacos or as a topping?
Greek yogurt, cashew cream, and coconut cream all hold their shape well when dolloped on tacos, chili, or baked potatoes. Greek yogurt is the closest in flavor to sour cream. Cashew cream and coconut cream both work for a dairy-free version, and a squeeze of lime juice helps either one taste closer to the tangy original. If Mexican crema is already in your fridge, it works too, though its thinner, slightly sweeter profile means it drizzles more than it dollops. Plain yogurt and buttermilk are both too thin to use as a topping without straining first.
What is a dairy-free or vegan substitute for sour cream?
Cashew cream and coconut cream or coconut yogurt are the two best dairy-free substitutes for sour cream. Cashew cream comes from raw cashews soaked, drained, and blended with water and a splash of lemon juice or vinegar for tang. Coconut cream comes from the solid layer of a chilled can of full-fat coconut milk and adds a mild coconut flavor. Both work at a 1:1 ratio in sauces, dips, and toppings.
Can I use buttermilk instead of sour cream?
Yes, especially in baking. Use 3/4 cup of buttermilk for every 1 cup of sour cream called for, and consider reducing other liquids in the recipe slightly to account for the added moisture. Buttermilk is much thinner than sour cream and curdles easily under direct heat, so it works best in baked goods, dressings, and pancake batter rather than hot sauces or dolloped toppings.
Can I make my own sour cream at home?
Yes. Combine 1 cup of heavy cream with 2 tablespoons of buttermilk in a clean jar, cover loosely, and let it sit at room temperature for 12 to 24 hours until it thickens. Once it reaches a thick, tangy consistency, refrigerate it and use it just like store-bought sour cream. See what can I use instead of heavy cream if you are also short on the heavy cream this method requires.
What can I use instead of sour cream in stroganoff?
Crème fraîche is the best substitute for sour cream in stroganoff, since the sauce needs to simmer without breaking. Greek yogurt also works if you stir it in off the heat at the very end of cooking rather than letting it simmer with the meat and mushrooms. Both swap in at a 1:1 ratio.
Can I use ricotta instead of sour cream?
Yes, especially in baked goods and pasta sauces. Ricotta swaps in at a 1:1 ratio and has a similarly mild flavor and creamy texture, though it lacks sour cream’s characteristic tang since it is not fermented. Whisk in a teaspoon of lemon juice or vinegar per cup to bring the flavor closer to the original. Choose whole-milk ricotta for the richest result.
Can I use kefir instead of sour cream?
Yes, particularly in soups, stews, and dressings where a pourable consistency is not a problem. Use plain, unsweetened kefir at a 1:1 ratio, or cut the amount in half in a dip that needs more body. Kefir is much thinner than sour cream, so it is not a good choice for dolloping on tacos or baked potatoes.
