What is crème fraiche and how do you make it?

In a nutshell, it’s thickened cream; a rich, thick, creamy wonderfulness.

Made with heavy whipping cream and buttermilk, this crème fraiche recipe is beyond easy to make. In my quest for a sour cream replacement (so I can stop bringing home those plastic tubs of store bought sour cream) I’ve experimented with a couple of different recipes. For topping tacos, this crème fraiche recipe got thumbs up as the best of the recipes I tried.

The homemade sour cream recipe I made results in a somewhat tangier, somewhat looser option than this creme fraiche.

These recipes are so similar, they’re kind of interchangeable in recipes. Which one you choose to make may just depend on availability of ingredients. You may not always have buttermilk on hand; if you don’t, use my sour cream recipe instead. (Lemon juice is a staple in most refrigerators, right?) That sour cream recipe is perfect for making dips and makes a fine creme fraiche substitute.

Here’s a trick, though. When you buy buttermilk to make these buttermilk biscuits, freeze the leftover buttermilk in ice cube trays. Measure two tablespoons into one cell of an ice cube tray, then pour buttermilk into the remaining cells to match that level. (That way you don’t need to measure each and every one!) When you’re ready to make a batch of crème fraiche, pop out a cube, let it melt, then stir it into the cream as directed.

Here’s how to make creme fraiche in a nutshell: combine two ingredients — that will take you five minutes or less. Let them stand at room temperature. I know, letting dairy products sit at room temperature goes against everything you’ve been taught. But trust me on this. Left to sit, the ingredients will thicken. Stir the mixture and store it in an airtight container in the fridge.

Making this recipe is as easy as can be and completely eliminates the need to buy sour cream in plastic containers. It’s an easy step to embrace on your path to using less plastic!

    Can you freeze heavy cream & then use it for this recipe as well?

      I have not tried this; let us know how it turns out if you do!

    I had made this once with store bought buttermilk and it came out perfectly! But recently I’d made some homemade butter that left me with plenty of buttermilk so I used that and this time it took almost 48 hours to even get moderately thick. What did I do wrong?

      Most store bought buttermilk is *cultured. I imagine that’s the difference.

      • SUZANNE Apr 11, 2020 @ 10:44

        What exactly do you mean by cultured when you refer to buttermilk. Is this a special process used to make commercial buttermilk?

  • Tracy Nelson Jun 23, 2019 @ 2:08

    This looks great. If I’m not able to use it all up in two weeks, will it freeze well?

    • Kris Bordessa Jun 23, 2019 @ 8:27

      I’d be more inclined to halve the recipe if you didn’t think you’d use it all. Freezing will work, but the texture will change slightly. (Good for baking with, though.)
