Best subs for sour cream in mashed potatoes

Creme fraiche

Don’t have sour cream? Creme fraiche is a suitable way to replace sour cream in mashed potatoes. Creme fraiche is a thick, creamy soured cream that has a slightly tart flavor and thus can easily replace sour cream in any recipe, including mashed potatoes. It is a french product so this will add abt of a french twist to your mash.

Crème fraîche is both thicker and fattier than the more tangy sour cream which is low in fat and more liquid-like. However, not only will you get a nice subtly tartness in a creme Fraiche mashed potatoes, but you’ll also have some very fluffy mash too!

Since creme fraiche and sour cream are alike, a 1:1 substitution can be used (that is, if a recipe calls for ½ cup of sour cream, replace it with ½ cup of sour cream).

Greek Yogurt

Vegan sour cream

Whether you use homemade vegan sour cream or store-bought vegan sour cream, this is another great sour cream substitute for mashed potatoes. While vegan sour cream does not taste exactly like full-fat sour cream, it is a nice vegan alternative that will work quite well in place of full-fat sour cream, especially when used together with a rich, slightly tangy vegan butter like Miyoko’s.

Heavy cream

Heavy cream

While heavy cream will not produce a slightly tangy mashed potato recipe, it can be used in a pinch to make some delicious creamy mash, which will be way creamier than the lighter mash made with sour cream. And if you want that nice tangy flavor that you’d get with sour cream, squeeze some lemon juice in the mash then mix.

Heavy whipping cream

Heavy whipping cream is very much like heavy cream and is often used to make mashed potatoes too. Use it in a pinch as an alternative to sour cream in mashed potatoes if you don’t mind not having that tangy flavor.

Milk and butter

Another great replacement for sour cream in mash potatoes is a combination of non-dairy milk and butter. This substitute makes for a less creamy mash recipe, however, with a few additions, this recipe can taste very good! Also, if you want to make this recipe completely vegan, then use a combination of non-dairy milk and vegan butter instead.
