Frequently Asked Questions (FAQs)

Why do you put sour cream in mashed potatoes?

Most mashed potato recipes call for milk and butter, but sour cream makes them so creamy with just enough tang. It also helps to cut down on the rich flavor.

Can I substitute sour cream for milk in mashed potatoes?

Yes, you can substitute sour cream for all milk. But you won’t get that “tang” associated with sour cream. Also, the milk quantity is really just a starting point. You can add more milk for thinner potatoes or less milk for thicker mashed potatoes.

What happens when you cook with sour cream?

Sour cream adds moisture without thinning your batter the same way that a liquid would. That fact that sour cream delivers moisture without further thinning out a batter results in a cake with a very tender, very fine crumb.

How to store sour cream mashed potatoes?

You can absolutely freeze any extras you make for later. Freezer bags –  Put  2 cups of sour cream mashed potatoes into each freezer bag, flatten it with your hands then squeeze out any extra air, zip up the bag, and then store in your freezer.


Sour cream mashed potatoes are so good. The tangy flavor of the sour cream cuts down the richness. Homemade fluffy mash is truly the best!
