Homemade Béarnaise Sauce Recipe: Tarragon-Infused Emulsion Perfection

This tarragon-infused sauce transforms steak and vegetables into restaurant-quality dishes with minimal effort. I’ve perfected the emulsification process to ensure a silky, stable result every time.

Using butter, egg yolks, and fresh herbs, this homemade version captures the classic French flavor without compromising on texture. Serve immediately or store briefly—it’s that versatile.

Ingredients for Homemade Bearnaise Sauce

Nine ingredients create this silky, tarragon-kissed French classic sauce with professional precision.

The butter quality is non-negotiable here. European-style unsalted butter (like Plugrá or Kerrygold) delivers the rich, creamy base this sauce demands. Clarifying it removes milk solids that could break your emulsion. Use fresh tarragon—dried simply won’t deliver the bright, anise-like flavor essential to béarnaise. Whole Foods or Farmer’s markets often carry the French variety, which is more delicate and aromatic.

No tarragon vinegar? White wine vinegar with an extra pinch of dried tarragon works. Shallots can be swapped for finely minced red onion if that’s what you have, though the flavor will be slightly sharper. For a non-alcoholic version, rice vinegar is a suitable substitute. The egg yolks must be room temperature—cold yolks resist emulsification. If you’re nervous about raw eggs, pasteurized yolks are an option.

Béarnaise is best served immediately—it’ll hold at warm room temperature for 1-2 hours. Refrigerate in a sealed container for up to 2 days, but reheat gently (or risk breaking the emulsion). Freezing isn’t recommended—it’ll separate. Always make this fresh for restaurant-quality results.

Step-by-Step Instructions for Homemade Béarnaise Sauce

Master the classic French technique for a velvety tarragon-infused emulsion that never breaks.

Step 1: Reduce Aromatics in Vinegar

In a small saucepan, combine the 2 tbsp white wine vinegar, finely minced shallots, 0.5 tsp black peppercorns, and 2 tbsp fresh tarragon. Bring to a gentle simmer over medium heat.

Reduce the mixture by half, until it becomes syrupy and the shallots appear translucent—this typically takes 3-4 minutes. This concentration step is crucial for developing the sauce’s signature depth of flavor. Strain through a fine-mesh sieve into a heatproof bowl, pressing gently to extract all liquid.

Step 2: Clarify the Butter

Melt the 1 cup unsalted butter in a small saucepan over low heat. As it melts, the butter will separate into three layers: foam on top, clarified butter in the middle, and milk solids at the bottom.

Carefully skim off the foam with a spoon. You want only the clear golden liquid—about ¾ cup—for your sauce. Keep the clarified butter warm (not hot) in a small pitcher near your workstation. Discard the milk solids, as they would cause the emulsion to break.

Step 3: Temper the Egg Yolks

Whisk the 3 whole egg yolks and 0.25 tsp salt in a heatproof bowl until pale and slightly thickened, about 1 minute. Place the bowl over a saucepan of barely simmering water (bain-marie), ensuring the bottom doesn’t touch the water.

Slowly drizzle in the warm vinegar reduction while whisking constantly. Continue whisking over the bain-marie for 2-3 minutes until the mixture thickens enough to leave a ribbon trail when the whisk is lifted. This tempering process prepares the yolks to accept the butter without scrambling.

Step 4: Emulsify with Clarified Butter

With the bowl still over the bain-marie, gradually drizzle in the warm clarified butter, starting with a few drops at a time while whisking vigorously. As the emulsion begins to form and thicken, you can increase to a thin stream.

After incorporating about half the butter, remove from heat and continue whisking as you add the remainder. If the sauce becomes too thick, whisk in 1 tsp warm water to adjust consistency. The finished sauce should coat the back of a spoon and have a velvety texture.

Step 5: Finish and Adjust Seasoning

Stir in the 1 tbsp lemon juice and 1 tsp fresh chervil to the sauce. Taste and adjust seasoning with additional salt or lemon juice as needed.

If the sauce breaks (appears greasy or separated), immediately place the bowl in ice water and whisk vigorously to re-emulsify. Serve warm but not hot, as excessive heat will cause separation. The sauce will hold for 1-2 hours at room temperature or can be gently reheated in a bain-marie.

Perfect Pairings for This Recipe

Protein Pairings

This sauce was born to elevate grilled steak, especially a medium-rare ribeye or filet mignon. I also love it with pan-seared salmon—the buttery richness complements the fish beautifully. For a budget-friendly option, try it with grilled chicken breasts or pork tenderloin. 💛

Vegetable Sides

Drizzle over steamed asparagus or roasted broccoli to transform simple veggies into gourmet sides. It’s also divine with grilled artichokes or a warm potato purée. The tarragon notes pair especially well with spring vegetables like fresh peas or roasted carrots.

Egg Dishes

Béarnaise turns breakfast into a luxury. Spoon it over poached eggs on toast or a classic Eggs Benedict. I also add a dollop to scrambled eggs for extra richness. The acidity cuts through the richness perfectly.

Starch Partners

Toss with hot buttered pasta for a quick, elegant meal. It’s also fantastic with crispy roasted potatoes or a simple baked potato. For a French bistro touch, serve with classic fries for dipping. 🍷

Beverage Pairings

A crisp Sauvignon Blanc or Chardonnay balances the sauce’s richness. For red wine lovers, a light Pinot Noir works beautifully. Non-alcoholic? Try a sparkling water with lemon to cleanse the palate between bites.
