📝 About This Recipe

Considered the sophisticated child of Hollandaise, Béarnaise is a cornerstone of classic French gastronomy, originating from the outskirts of Paris in the 1830s. This luxurious emulsion marries the richness of clarified butter and egg yolks with a sharp, aromatic reduction of shallots, peppercorns, and fresh tarragon. It is the ultimate accompaniment for a perfectly seared steak, offering a creamy texture and a bright, herbaceous finish that elevates any meal to a fine-dining experience.

🥗 Ingredients

The Reduction

  • 1/4 cup Dry White Wine (such as Sauvignon Blanc or Chardonnay)
  • 1/4 cup White Wine Vinegar (high quality)
  • 2 tablespoons Shallots (very finely minced)
  • 2 tablespoons Fresh Tarragon (stems reserved, leaves finely chopped)
  • 1 tablespoon Fresh Chervil (finely chopped (optional))
  • 1/2 teaspoon Black Peppercorns (coarsely cracked)

The Emulsion

  • 3 large Egg Yolks (at room temperature)
  • 1 cup Unsalted Butter (clarified and kept warm (approx. 225g))
  • 1 teaspoon Lemon Juice (freshly squeezed)
  • 1/4 teaspoon Kosher Salt (or to taste)
  • 1 pinch Cayenne Pepper (for a subtle warmth)
  • 1 teaspoon Warm Water (to adjust consistency if needed)

👨‍🍳 Instructions

  1. 1

    In a small heavy-bottomed saucepan, combine the white wine, white wine vinegar, minced shallots, cracked peppercorns, and the reserved tarragon stems.

  2. 2

    Place the saucepan over medium heat and bring the mixture to a simmer. Reduce the liquid by about two-thirds until you have approximately 1.5 to 2 tablespoons of concentrated liquid remaining.

  3. 3

    Strain the reduction through a fine-mesh sieve into a small bowl, pressing on the solids to extract every drop of flavor. Discard the solids and let the liquid cool slightly.

  4. 4

    Prepare a bain-marie (double boiler) by bringing an inch of water to a gentle simmer in a medium pot. Ensure the bottom of your heatproof mixing bowl will not touch the water.

  5. 5

    Place the egg yolks and the strained reduction into the heatproof bowl. Whisk vigorously for about 1-2 minutes until the yolks become pale, frothy, and slightly thickened.

  6. 6

    Place the bowl over the simmering water. Continue whisking constantly in a figure-eight motion. Do not let the eggs get too hot or they will scramble; lift the bowl occasionally to regulate the heat.

  7. 7

    Whisk until the yolks have doubled in volume and are thick enough that the whisk leaves a visible trail (ribbon stage). This usually takes 3-5 minutes.

  8. 8

    Remove the bowl from the heat. Begin adding the warm clarified butter, literally one drop at a time at first, whisking constantly to establish the emulsion.

  9. 9

    Once the sauce begins to thicken and stabilize, you can start pouring the butter in a very slow, thin, steady stream while continuing to whisk vigorously.

  10. 10

    If the sauce becomes too thick, whisk in a teaspoon of warm water or lemon juice to thin it out before continuing with the butter.

  11. 11

    Once all the butter is incorporated, fold in the finely chopped fresh tarragon leaves and chervil.

  12. 12

    Season with kosher salt, cayenne pepper, and a few drops of lemon juice to brighten the flavors. Taste and adjust seasoning as necessary.

  13. 13

    Keep the sauce in a warm spot (like near the stove) until ready to serve. Do not refrigerate or overheat, as the emulsion will break.

💡 Chef's Tips

Always use clarified butter for the smoothest texture; the milk solids in whole butter can make the sauce greasy. If the sauce breaks (separates), whisk a fresh egg yolk in a clean bowl with a teaspoon of warm water, then slowly whisk the broken sauce into it. Temperature control is vital; your clarified butter should be warm to the touch (about 110°F/43°C), not piping hot. For the best flavor, use only fresh tarragon; dried tarragon lacks the essential oils and anise-like punch required for this dish. Never make this sauce too far in advance; it is best served within 30-60 minutes of preparation.

🍽️ Serving Suggestions

Serve generously over a grilled Filet Mignon or Chateaubriand. Pair with blanched asparagus or roasted long-stemmed broccoli for a vegetarian treat. Drizzle over poached eggs and smoked salmon for a luxurious 'Eggs Royale' twist. Accompany with a crisp French fries (Frites) for the classic Steak-Frites experience. Enjoy with a glass of structured Cabernet Sauvignon or a buttery oaked Chardonnay.
