Bearnaise Sauce Recipe UK: Classic French Emulsion With Tarragon

There’s a reason béarnaise has endured as a classic—this rich, tarragon-infused sauce elevates steak, fish, and eggs to restaurant quality. The key is patience and precision.

With double cream and fresh herbs, this version delivers the authentic French flavor you expect. The emulsion comes together beautifully with careful temperature control.

Ingredients for Bearnaise Sauce Recipe Uk

Ten ingredients for that rich, tarragon-kissed French classic everyone loves.

The tarragon is non-negotiable here—fresh only, no dried stuff. Waitrose or M&S usually have the best bundles. If you can’t find chervil (totally fair, it’s elusive), just double the tarragon. The shallots should be super fine—almost paste-like—so they melt into the reduction. For the vinegar, a proper tarragon vinegar (from Sainsbury’s Taste the Difference range) takes this to another level.

No double cream? Heavy cream works, but the UK version is thicker and richer. Out of tarragon? A pinch of dried in the reduction, but fresh at the end is a must. For the clarified butter, melt slowly and skim off the milk solids—don’t rush this part (worth the extra minute). If you’re nervous about raw eggs, pasteurized yolks are fine, but the texture might be slightly less silky.

Béarnaise doesn’t keep long—2 days max in the fridge. Reheat gently in a bain-marie, but it might split. Best made fresh. Leftovers? Stir into mashed potatoes for a next-level side.

Step-by-Step Instructions for Béarnaise Sauce

Master this classic French emulsion with precise technique and perfect timing.

Step 1: Infuse the Vinegar Reduction

Combine the 3 tbsp White Wine Vinegar, 2 tbsp Shallots, 1 tsp Black Peppercorns, 2 tbsp Fresh Tarragon Leaves, and 1 tbsp Fresh Chervil Leaves in a small saucepan. Simmer over medium heat until the liquid reduces by half—you’ll see it turn syrupy and the shallots become translucent.

This step concentrates the flavors and mellows the sharpness of the vinegar. Remove from heat and let it steep for 5 minutes to deepen the tarragon and chervil infusion. Strain through a fine-mesh sieve, pressing gently on the solids to extract all liquid. Discard the solids.

Step 2: Temper the Egg Yolks

In a heatproof bowl, whisk the 2 whole Egg Yolks, 1 tsp Dijon Mustard, 1 tsp Lemon Juice, and 0.25 tsp Salt until pale and slightly thickened. Place the bowl over a pot of barely simmering water, ensuring the bottom doesn’t touch the water (a double boiler setup).

Whisk constantly for 2-3 minutes until the mixture thickens enough to leave a visible trail when you lift the whisk. This is your base for the emulsion. Remove from heat immediately if it starts to look grainy—this means you’ve overheated the yolks.

Step 3: Emulsify with Clarified Butter

Slowly drizzle in the 0.5 cup Unsalted Butter (melted and clarified) while whisking vigorously. Start with a thin stream, then increase to a steady pour as the sauce begins to thicken. The mixture should turn pale and creamy, coating the back of a spoon.

If the sauce starts to separate, don’t panic. Remove the bowl from heat and whisk in 1 tsp of cold Double Cream to bring it back together. Keep the sauce warm but not hot—egg yolks will scramble above 120°F.

Step 4: Finish with Cream and Herbs

Gradually whisk in the remaining 0.5 cup Double Cream until fully incorporated. The sauce should now have a velvety texture and a light, airy consistency. Stir in any reserved tarragon or chervil from the infusion for extra herbaceousness.

Taste and adjust seasoning with a pinch more Salt or a drop of Lemon Juice if needed. The sauce should balance rich, tangy, and slightly peppery notes. Use immediately, or keep warm in a thermos or double boiler for up to 1 hour.

Dietary Considerations for This bearnaise sauce recipe uk

Gluten-Free Friendly

This sauce is naturally free from gluten, making it perfect for those avoiding wheat or with coeliac disease. Just ensure your Dijon mustard is certified gluten-free, as some brands use wheat flour as a thickener. Maille is a safe bet I always keep in my pantry.

Dairy Considerations

The double cream and unsalted butter make this a rich, dairy-heavy sauce. For lactose intolerance, you can try lactose-free heavy cream, though the texture might differ slightly. Unfortunately, there’s no perfect vegan substitute for the egg yolks in this classic version.

Egg Allergy Warning

This recipe contains raw egg yolks, so it’s not suitable for anyone with an egg allergy. If you’re concerned about salmonella, use pasteurized egg yolks—they’re widely available in UK supermarkets like Tesco or Sainsbury’s. 💡

Low-Carb & Keto

With only 3g net carbs per serving (mostly from shallots), this fits perfectly into low-carb or keto diets. The fat content is high, which aligns well with keto macronutrient goals. Just watch your portion size if you’re counting calories.

Pregnancy Note

Due to the raw egg yolks, pregnant women should avoid this sauce unless made with pasteurized eggs. The risk of salmonella is low but not zero, and it’s always better to err on the side of caution during pregnancy.

Storage Caution

Because of the raw eggs, this sauce doesn’t keep long. Consume within 2 days when refrigerated, and reheat gently to avoid breaking the emulsion. Never freeze béarnaise—it separates irreparably. 🥛
