It’s the perfect accompaniment for steak, grilled fish, eggs, or vegetables. With its tangy, buttery flavor and silky texture, it’s the ultimate finishing touch for an elegant meal!

Ingredients

Scale
  • ½ cup (120 ml) white wine vinegar
  • ½ cup (120 ml) dry white wine
  • 2 tablespoons shallots, finely minced
  • 2 tablespoons fresh tarragon, chopped (plus extra for garnish)
  • 1 tablespoon fresh chervil (optional, for authenticity)
  • 3 large egg yolks
  • 1 cup (225 g) unsalted butter, melted and warm
  • ½ teaspoon Dijon mustard (optional, for stability)
  • Salt and black pepper, to taste
  • Lemon juice, to taste

Instructions

1. Make the reduction:

  • In a small saucepan, combine white wine vinegar, white wine, shallots, half of the tarragon, and chervil (if using).
  • Simmer over medium heat until the liquid reduces by half.
  • Strain the mixture and let it cool slightly.

2. Prepare the egg base:

  • In a heatproof bowl, whisk together the egg yolks and the strained vinegar reduction.
  • Place the bowl over a pot of simmering water (double boiler method), making sure the bowl doesn’t touch the water.
  • Whisk continuously until the mixture thickens slightly (about 3-4 minutes).

3. Add the butter:

  • Remove from heat and slowly drizzle in the melted butter, whisking constantly until the sauce is thick and creamy.
  • Stir in the remaining tarragon, and season with salt, black pepper, and a few drops of lemon juice.

4. Serve immediately:

  • Serve warm over steak, grilled fish, or vegetables. Garnish with extra tarragon if desired.

Notes

  • Keep the heat low during cooking to prevent the eggs from scrambling.
  • If the sauce becomes too thick, thin it out with a little warm water or more lemon juice.
  • Béarnaise sauce is best served fresh, but it can be kept warm for up to 30 minutes by placing the bowl over a warm water bath.
