The science behind it: fermentation
The magic of crème fraîche happens through a simple fermentation process:
- Heavy cream provides the rich, fatty base (18-20% fat content)
- Plain yogurt introduces beneficial bacteria
- Time and warmth allow these bacteria to work their magic, naturally thickening the cream without spoiling it
Ingredients for creme fraiche
It’s like magic to watch creme fraiche thicken right before your eyes! All you need is 24 hours and a warm place. It’s a nice way to use up leftover cream, or perfect if you can’t find creme fraiche at the store and have 1 day to wait. Here’s what you need to make creme fraiche (go to the recipe for instructions):
- 1 cup heavy cream (with 18-20% fat content)
- 1 tablespoon plain yogurt (Greek or regular)

Ways to use homemade crème fraîche
Creme fraiche is a French version of sour cream, but it’s even richer and thicker. Creme fraiche has a higher fat content and a less tangy flavor than sour cream. This velvety cultured cream is used in many ways: as a creamy dip for veggies, for dolloping soups, or even a spoonful over fruit or a dessert. It doesn’t separate or curdle when heated, ideal for making creamy sauces. Here are some of our favorite ways to use it:
Savory dishes
- Swirl into hot soups for added richness; try it in potato soup or butternut squash soup
- Stir it into marinara sauce to make a creamy pasta sauce that won’t separate when heated
- Add to vegetarian lasagna instead of ricotta
- Dollop onto spicy dishes for cooling contrast
- Enhance potato dishes, from mashed to gratins
- Add luxury to scrambled eggs or omelets
Sweets
- Top fresh berries or stone fruits
- Garnish warm desserts like apple crumble or bread pudding
- Whip with a little sugar for a sophisticated cake frosting
- Serve alongside scones or quick breads
- Blend into smoothies for extra richness
Dietary notes
This homemade creme fraiche recipe is vegetarian and gluten-free.
Frequently asked questions
After 24 hours, it should be noticeably thicker but may still be slightly fluid. It will continue to thicken in the refrigerator. If it’s still very liquid after 24 hours, your room temperature might be too cool – try moving it to a slightly warmer spot.
Plain yogurt (regular or Greek) works best. Avoid flavored varieties or those with added stabilizers. The yogurt just needs to contain live cultures to start the fermentation process.
Common culprits include:
Ultra-pasteurized cream (though it can still work, it may take longer)
Room temperature too cool
Yogurt without active cultures
Container not clean enough
