What Can I Substitute for Sour Cream? Best Options

For a quick sour cream substitute, use plain Greek yogurt in equal measure; it has a similar creamy texture and pleasantly tangy flavor. This simple whisked mixture loosens thick yogurt with a little milk, and the guide below explains when other swaps work better in dips, baking, sauces, and toppings.

Ingredients

1 cup (245 g) plain full-fat Greek yogurt
1 tablespoon (15 ml) milk, preferably whole milk, to loosen the yogurt
1 teaspoon (5 ml) lemon juice, optional, for extra tang
⅛ teaspoon (about 0.7 g) fine salt, optional, for a savory dip or topping

Instructions

Add the Greek yogurt to a small bowl. Measure in the milk and, if you want a sharper sour-cream-like tang, the lemon juice. Add the salt only if the mixture will be used in a savory dish; leave it out for baking or a sweet topping.
Whisk for about 1 minute, scraping the sides of the bowl, until smooth and evenly loosened. For a thicker dip or dollop, start with 1 teaspoon of milk instead of the full tablespoon. For a pourable sauce, add milk a teaspoon at a time until it reaches the consistency you need.
Let the mixture stand for 10 minutes in the refrigerator so the flavors can settle. Taste it, then add a little more lemon juice or salt if appropriate. Use the finished mixture as a 1:1 replacement for sour cream in dips, toppings, and many recipes. This batch makes slightly more than 1 cup, so measure out 1 cup when a recipe calls for exactly that amount.

Tips

Choose the right yogurt. Plain, unsweetened Greek yogurt is the closest everyday match because it is thick and tangy. Regular plain yogurt is thinner; strain it through a fine-mesh sieve lined with cheesecloth in the refrigerator until it thickens, or use it as-is in smoothies, marinades, and looser sauces.
Adjust gradually. Yogurt brands vary in thickness and acidity. Add milk in small amounts rather than pouring it all in at once, and taste before adding lemon juice. Too much liquid can make a dip runny, while extra acid can make an already-tart yogurt taste harsh.
Be careful with heat. Yogurt can separate when boiled or added cold to a very hot sauce. Use full-fat yogurt when possible, bring it closer to room temperature, stir it in near the end, and keep the dish at a gentle simmer rather than a hard boil. For a hot recipe, a dairy alternative such as crème fraîche may tolerate heat better.
Keep it cold and clean. Refrigerate the mixture promptly and use a clean spoon each time. Do not leave it at room temperature for more than 2 hours; in a very warm room above 90°F (32°C), the limit is 1 hour.

Serving Suggestions

Use the yogurt mixture wherever sour cream is spooned on after cooking. It is good on baked potatoes, chili, tacos, quesadillas, and roasted vegetables, and it adds a cool, tangy contrast to spicy or richly seasoned food. For a garnish, keep it thick and add a small spoonful rather than thinning it with extra milk. If the food is very hot, let it stop steaming for a minute before adding the topping; the yogurt is less likely to loosen or split.

For dips, stir in chopped herbs, minced garlic, black pepper, or a little grated cucumber. The plain base also works as a quick topping for soups, but swirl it in off the heat instead of boiling it. If serving a crowd, set the bowl over ice or return it to the refrigerator between servings, particularly if it will be out for an extended meal.

Variations

Plain Greek yogurt, straight from the tub: This is the easiest swap for many uses. Replace sour cream with the same amount of plain Greek yogurt in dips, cold sauces, toppings, and many baking recipes. Choose full-fat yogurt for a rounder flavor and richer texture; nonfat yogurt works, but can taste sharper and may be less creamy. You can leave out both the milk and lemon when the yogurt already has the right consistency and tang.

Regular plain yogurt: Use it as a 1:1 replacement in smoothies, marinades, and recipes where a thinner texture is acceptable. For a thicker topping or dip, strain it until it resembles Greek yogurt. Straining takes additional time, so plan ahead and keep the yogurt refrigerated while it drains. Do not use sweetened or flavored yogurt in savory food.

Crème fraîche: Swap it cup for cup when you want a rich, mildly tangy substitute, particularly in warm sauces. It is generally less likely than yogurt to curdle when heated, though gentle heat is still a good idea. Its flavor is less sharp and its texture richer than sour cream, so it may change the character of a delicate dip or topping.

Full-fat cottage cheese: Blend 1 cup (about 225 g) until smooth, then use it as a dip or topping substitute. It is milder and less tangy than sour cream, and blending removes the curds but does not make it identical. A small squeeze of lemon can brighten it. This is a practical option for cold preparations, but it is not the most predictable choice for cakes or delicate baking.

For dairy-free cooking: Use an unsweetened, unflavored dairy-free sour cream product in a 1:1 ratio when available. Unsweetened soy or coconut yogurt can work in dips and toppings, but check the label: vanilla flavoring or added sugar will be noticeable, and coconut can bring a distinct flavor. A plant-based yogurt may also be thinner, so add it gradually in sauces and choose a thicker style for dolloping.

For baking: Plain full-fat Greek yogurt is usually the most straightforward substitute, measured cup for cup. It brings moisture and acidity, but the final crumb can be a little less rich or tender than a recipe made with sour cream. Crème fraîche can be a closer rich-textured option. Avoid assuming that every dairy-free yogurt or blended cottage cheese will behave the same way in a cake or quick bread; their fat, water, and acidity vary.

Storage and Reheating

Store the prepared mixture in a clean, covered container in the refrigerator and use it within 3 to 4 days, or sooner if the yogurt package has an earlier use-by date. Refrigerate it within 2 hours of mixing. Stir before serving if a little liquid separates; discard it if it develops an off smell, unusual discoloration, or mold. Do not freeze this mixture for use as a fresh topping, because thawing can leave it grainy or watery.

This is a cold substitute, so it does not need reheating. If you are using it in a cooked dish, warm the dish itself gently and stir in the yogurt near the end, or temper it by whisking a spoonful of warm sauce into the yogurt before adding the mixture back to the pan. Avoid bringing a yogurt-based sauce to a boil. For leftover cooked food, refrigerate within 2 hours and use within 3 to 4 days; reheat leftovers to 165°F (74°C), then add fresh yogurt after reheating if you want a cool topping.

Frequently Asked Questions

Can I use plain yogurt instead of sour cream?
Yes. Plain Greek yogurt is usually the closest easy swap, and it can replace sour cream in equal amounts for many dips, toppings, sauces, and baked goods. Regular plain yogurt is thinner, so use it where that texture is suitable or strain it first. Check that it is unsweetened and unflavored.

What is the best substitute for sour cream in baking?
Full-fat plain Greek yogurt is a practical 1:1 option for many cakes, muffins, and quick breads. It provides moisture and acidity, although the result may be slightly less rich or have a different crumb. Crème fraîche can provide more richness. Because recipes differ, avoid changing several other ingredients at the same time when making the swap.

Can I replace sour cream with mayonnaise?
Mayonnaise can work in some savory dips, dressings, and sauces, but it is not a close flavor match: it is richer, less tangy, and usually made with oil and egg. Start by replacing only part of the sour cream with mayonnaise, then taste and add lemon juice or vinegar if the recipe needs more acidity. It is not a dependable choice for sweet baking.

How much Greek yogurt replaces 1 cup of sour cream?
Use 1 cup (245 g) plain Greek yogurt as a starting point for 1 cup of sour cream. If it is too thick for the recipe, stir in milk a teaspoon at a time. Add lemon juice only if you want more tang; some Greek yogurt is already quite tart. For this article’s mixed substitute, measure 1 cup of the finished mixture because the added milk makes the batch a little larger than a cup.

Can I use sour cream substitutes in a hot sauce?
Often, but the method matters. Yogurt is more prone to separating under high heat than crème fraîche, so use full-fat yogurt, avoid boiling, and stir it in at the end. If the recipe calls for prolonged simmering, choose a heat-friendlier substitute or follow the recipe’s directions for adding dairy gradually.

What can I use if I need a dairy-free sour cream substitute?
A plain, unsweetened dairy-free sour cream is the most direct option. Unsweetened soy yogurt can work in many dips and sauces, while coconut yogurt may add a noticeable coconut flavor. Look for a thick, unflavored product and taste it before using; sweetness, acidity, and thickness vary considerably between brands.
