What Is Crème Fraîche?
Crème fraîche is a cultured cream originating from France and is made by inoculating heavy cream with specific strains of lactic acid bacteria. This process thickens the cream and imparts a delicate tang. It contains a high butterfat content (typically 30-45%), making it rich, smooth, and stable when heated. Unlike many other dairy products, crème fraîche does not easily curdle, even in hot dishes, making it highly prized in cooking .
Terminology
- The French term crème fraîche literally means “fresh cream.” However, in France, it may also refer to a liquid cream unless specified as crème fraîche épaisse (thick cream) or fermentée (fermented). Internationally, it usually refers to the thick, cultured version.
- Products similar to crème fraîche can be found in other cuisines, such as the Central American crema fresca .
History and Origins
Crème fraîche has deep roots in the dairy traditions of northern Europe, with a particularly strong association with French cuisine. It was first made by allowing fresh cream from cow’s milk to ferment naturally, thanks to the beneficial bacteria present in farm environments. Over time, this process was refined to ensure consistent quality and safety, evolving into the cultured product beloved today .
How Crème Fraîche Is Made
The modern production of crème fraîche involves introducing a specific starter culture (mainly Lactococcus cremoris, L. lactis, and L. lactis biovar diacetylactis) to pasteurized heavy cream. This mixture is left to ferment at a controlled temperature until the cream thickens and develops its characteristic flavor.
- Traditional recipe: Heavy cream is mixed with buttermilk or a commercial starter, then left at room temperature (20–22°C/68–72°F) for up to 24 hours until thickened .
- Commercial production: In Europe, only cream and starter culture are usually allowed; stabilizers are often prohibited .
- Low-fat options: In some countries, low-fat crème fraîche can be made using additives like xanthan gum, as the reduced fat content doesn’t provide the same stability and texture .

Key Characteristics and Physico-Chemical Properties
- Butterfat Content: Standard crème fraîche contains 30–45% fat; low-fat variants are around 15%.
- pH Level: The finished product has a pH close to 4.5, thanks to lactic acid bacteria .
- Texture: Its high fat and acid gel matrix produce a creamy yet firm consistency. Low-fat versions tend to be less stable, often requiring stabilizers for thickening.
- Stability: Crème fraîche is highly stable under heat, making it ideal for enrichment in hot dishes—unlike many other cultured dairy products.
Crème Fraîche vs. Sour Cream and Similar Products
| Aspect | Crème Fraîche | Sour Cream | Mascarpone/Cream Cheese |
|---|---|---|---|
| Fat Content | 30–45% | ~18–20% | ~40%/33% |
| Acidity (pH) | ~4.5 (mildly tangy) | Lower; sharper tang | Neutral |
| Texture | Thick, creamy, spoonable | Less stable, often lighter | Dense and spreadable |
| Cooking Stability | High—does not curdle easily | Low—may curdle when heated | High, but different flavor |
| Additives | Typically none (EU); sometimes stabilizers | May contain thickeners | Stabilizers, if processed |
| Flavor Profile | Rich and mildly tangy | Tart and tangy | Mild, slightly sweet |
Sour cream is more tangy and less rich than crème fraîche. While both are made by fermenting cream, crème fraîche’s higher fat content yields a more indulgent consistency and makes it less likely to separate in hot applications .
Benefits of Crème Fraîche
Though it’s an indulgence by caloric standards, crème fraîche offers numerous culinary and practical benefits:
- Culinary versatility: Enhances both sweet and savory dishes, from soups and sauces to desserts and spreads.
- Superior cooking stability: Due to its high fat content, it resists curdling—even when heated, baked, or vigorously stirred.
- Flavor enhancement: Its mild tangy profile brightens and balances other flavors in a dish.
Nutritionally, crème fraîche provides calcium, vitamin A, and beneficial fats. Unlike some industrial dairy products, traditional crème fraîche is free from artificial thickeners, and its fermentation introduces probiotics beneficial for gut health. However, due to its richness, moderation is recommended.
Culinary Uses of Crème Fraîche
The versatility of crème fraîche is legendary in both classic and modern cooking. It can be enjoyed:
- As a topping: Dolloped onto fresh fruit, pies, tarts, pancakes, or served with baked potatoes.
- In sauces: Swirled into pan sauces, cream sauces, veloutés, or gravies for silky body and delicate tang.
- With soups: Added at the end to enrich and garnish hot soups (e.g., vichyssoise, bisques, blended vegetable soups).
- Baked goods: Used in cakes, scones, or muffins for extra moisture and depth.
- In desserts: Paired with berries, poached fruit, or incorporated in trifles, cheesecakes, and parfaits.
- As a savory base: Mixed with herbs for quick dips, dressings, or served alongside smoked salmon or caviar.
- Finishing touch: Stirred into curries, stews, or pasta dishes for a smooth, rich finish.
Thanks to its heat stability, crème fraîche retains its creamy consistency even when added to simmering or boiling dishes .
Taste and Texture Profile
Crème fraîche is rich, creamy, and luxuriously thick, with a luscious mouthfeel. The taste is mildly tangy, subtly nutty, and less tart than sour cream. Its silkiness makes it easy to spread, dollop, or whisk into a dish, while its clean, fresh finish complements both sweet and savory foods. The higher butterfat content gives it a mellow roundness and opulent texture.
How to Make Crème Fraîche at Home
Making crème fraîche at home is simple and requires just two ingredients:
- 1 cup (250 mL) heavy whipping cream (avoid ultra-pasteurized)
- 2–3 tablespoons (30–45 mL) cultured buttermilk or sour cream with live cultures
- Gently stir together the cream and buttermilk in a non-reactive jar or bowl. Cover loosely with a clean cloth.
- Let stand at room temperature (20–22°C/68–72°F) for 12–24 hours, until thickened and fragrant (it should smell fresh and slightly nutty).
- Stir to blend, then refrigerate for 8+ hours before using. Homemade crème fraîche keeps for about one week in the fridge .
(Tip: If the mixture develops a very sour or unpleasant odor, discard and try again with fresh dairy.)
Frequently Asked Questions (FAQs)
Is crème fraîche healthy?
Crème fraîche is rich in fat and calories but also offers nutrients like calcium and vitamin A. Its fermentation process may provide beneficial probiotics, though it should be consumed in moderation as part of a balanced diet.
Can I substitute sour cream or yogurt for crème fraîche?
While sour cream or Greek yogurt can sometimes be used as substitutes, the taste and texture will differ—sour cream is tangier and more likely to curdle, while yogurt is less rich. For sauces or recipes requiring high heat, crème fraîche is superior.
Why does crème fraîche not curdle when cooked?
The high fat content of crème fraîche stabilizes its proteins, making it resistant to curdling, even at high temperatures—a big advantage for sauces and soups .
Can I freeze crème fraîche?
Freezing is not recommended as it can alter the texture, causing separation. For best results, use crème fraîche fresh from the refrigerator.
How long does crème fraîche last?
Store-bought crème fraîche typically lasts 1–2 weeks in the refrigerator. Homemade versions should be used within a week. Always check for unusual odors or mold before using.
