About this recipe

It's very easy to make sour cream at home. Add buttermilk to heavy cream or half-and-half. Let it rest for about 24 hours until it thickens to the consistency you like.

The mixing process takes about 30 seconds, while the resting process takes 24 hours. I typically mix up my homemade sour cream the night before I intend to use it. 

Ingredients for homemade sour cream

Heavy cream vs. half-and-half for sour cream

Heavy cream and half-and-half produce slightly different types of sour cream.

Heavy cream

The heavy cream variation (pictured above) is rich and buttery, but it still retains the tang that makes sour cream so delicious. It has the consistency of thick yogurt and makes a wonderful topping for everything from soups to nachos.

Half-and-half

The flavor of the sour cream made with half-and-half (pictured above) is also excellent, but it tends to be slightly thinner than a batch made with heavy cream. Still, it can be used in dips and in baking exactly the same way as store-bought sour cream.

Which is better?

I prefer the heavy cream variation of this recipe. It feels rich and decadent on your tongue, almost like eating a good ice cream. It is so rich that I actually use less of it with my dishes (and feel much more satisfied) than I would with a store-bought "low-fat" sour cream product. It is worth the splurge!

It also happens to be quite convenient for me, as I tend to have heavy cream in my refrigerator on a regular basis, since I make homemade ice cream frequently. 

Recipe for homemade sour cream

Makes about 1 cup

Ingredients:

  • 1/4 cup buttermilk
  • 1 cup heavy cream or 1 cup half-and-half

Step 1:

In a sealable container, such as a mason jar, combine buttermilk and heavy cream or half-and-half. Seal the container and shake well to combine. Keep out at room temperature, out of direct sunlight, for 24 hours.

Step 2:

Open your container and scoop out the sour cream. If using heavy cream, a layer of clear whey may form at the bottom of the container and should be drained off. Transfer sour cream to a clean, sealable container and refrigerate until ready to use.

After the sour cream has thickened, transfer it to the refrigerator and keep it chilled until you are ready to use it. Both varieties of sour cream will thicken slightly as they chill. I typically use mine within 1-2 days of making it, but it will keep in an airtight container for at least 5 days.

Sounds very interesting and yummy. Can you use powdered buttermilk instead of fresh?
Thanks.

Hello Mary,
I’m no expert but powdered milk is non-fat and this recipe needs a lot of fat to work. Notice that the half and half will produce a more liquid result.
You would probably end up with sour milk if you used the powdered version. Not recommended.

I would like to use fresh goats milk but will probably have to add heavy cream at around 50%. My goats only have 7 to 8% milk fat.

This sounds great! Sour cream is hard to come by sometimes where i live so a homemade recipe is pretty handy. However i can’t get buttermilk where i am either, do you think using the milk and lime juice/vinegar replacement would work for this?? Thanks!
