Best Sour Cream Substitutes
Out of Sour Cream? Here are 3 real substitutes, ranked and ratio-backed.
1. Greek yogurt
Ratio: 1:1
Very close in tang and thickness; slightly less fat, so baked goods can be marginally less rich, but the swap is close to seamless.
Best for: baking, dips, toppings
2. Plain yogurt
Ratio: 1:1
Thinner and less tangy than sour cream — works, but the result is noticeably looser as a topping.
Best for: baking
3. Cream cheese + milk
Ratio: 8 oz cream cheese thinned with 2-3 tbsp milk per 1 cup sour cream
Rich and tangy but denser; blend until smooth to avoid a lumpy texture.
Best for: dips, baking
Sour cream substitutes are some of the closest, most reliable swaps on this whole site — Greek yogurt in particular is close enough to sour cream in tang and thickness that many cooks use it as a permanent lower-fat alternative rather than just an emergency substitute.
All three options below lean on the same basic logic: something tangy and thick enough to mimic sour cream's texture, whether that's another cultured dairy product (yogurt) or a combination that gets there through blending (cream cheese thinned with milk).
The choice between them mostly comes down to what you already have and how close a match you need — Greek yogurt for the closest all-around swap, plain yogurt if that's what's on hand and a slightly thinner result is acceptable, or cream cheese and milk if you want something richer and don't mind a bit more blending work.
Crème fraîche stands apart from all three options ranked above for one specific reason: unlike sour cream, it can go directly into a simmering pan sauce without curdling, since its slightly different culturing process and higher fat content make it far more heat-stable — a genuine advantage for a hot sauce, though its milder tang means it's a less obvious pick for a cold dip or a baked good where sour cream's sharper flavor is the point.
Mayonnaise sometimes gets suggested online as a sour cream substitute, and it's worth being direct about why this site doesn't rank it here — mayonnaise is built from oil and egg rather than cultured dairy, so it lacks sour cream's tang entirely and behaves quite differently under heat, making it a poor stand-in for nearly everything sour cream is actually used for.

Frequently asked questions
Is Greek yogurt really a near-seamless substitute for sour cream?
It's arguably the strongest 1:1 swap anywhere on this site's substitution index — dolloped on chili, folded into a dip, or baked into a cake, it holds onto enough of sour cream's tang and body that the difference mostly shows up as a touch less richness rather than anything a taster would flag outright.
Why does plain yogurt make a thinner substitute than Greek yogurt?
Greek yogurt is strained to remove much of its whey, concentrating both its tang and its thickness — plain yogurt skips that straining step, so it's naturally looser and less tangy, which carries through into how it performs as a sour cream substitute.
Can I use the cream-cheese substitute for both baking and as a topping?
It works better in baking, where its extra richness blends into the batter — as a standalone topping it can taste noticeably denser and less tangy than real sour cream unless it's thinned and seasoned carefully.
Does the substitute change if the sour cream is going into a cold dip versus a baked dish?
Somewhat — Greek yogurt holds up well in both, but the cream-cheese-and-milk option is noticeably better suited to baking, where its extra richness blends into a batter, than to a cold dip, where its denser texture is more noticeable on its own.
Does the Greek yogurt substitute change the tanginess of a finished dish noticeably?
Only slightly — Greek yogurt is close enough in tang to sour cream that most people can't distinguish the swap in a finished dish, especially once other ingredients and seasonings are factored in.
