Béarnaise sauce is rich, buttery, and unapologetically herby. It’s like the sassier cousin of hollandaise sauce, built on egg yolks and melted butter, but with a sharp vinegar kick and loads of fresh tarragon.

The flavor is bold and bright, with just enough tang to cut through a juicy steak (or whatever you’re spooning it on). The texture? Silky, pourable, and straight-up decadent.

Here’s Why This Bearnaise Sauce Recipe Works

Immersion blender = no-fail emulsion: No whisking over a double boiler. This modern method nails the texture every time.

Two-stage tarragon hit: Infused early for depth, then chopped fresh at the end for brightness. (If you’re after a creamier, milder version, check out my tarragon cream sauce.

Hot butter does the heavy lifting: Melted butter “cooks” the yolks as it blends, thickening the sauce without fuss.

Built-in make-ahead option: The vinegar reduction holds fine until you’re ready to blend and serve.

Recipe Tips

Use a narrow container: A Mason jar or similarly tall container helps the immersion blender emulsify properly.

Don’t skip the strain: Removing the solids from the vinegar reduction keeps the texture smooth.

Keep butter hot, not sizzling: If it’s bubbling, let it cool a touch before blending to avoid curdling the yolks.

Thin at the end, not during: Add hot water after blending to adjust consistency without breaking the emulsion.

Salt to taste last: The acid and butter can mask salinity. Always finish with a final seasoning check.

Ingredients 

  • 3 tablespoons white wine vinegar
  • 3 tablespoons dry white wine
  • 1 shallot, thinly sliced
  • 3-4 sprigs fresh tarragon, (or 1 teaspoon dried)
  • 3 egg yolks
  • 2 sticks butter, (1 cup) cut into cubes
  • ¼ teaspoon salt, (or to taste)

Instructions 

  • In a small saucepan over medium-low heat, combine the vinegar, white wine, shallots, and about half of the tarragon. Simmer until reduced to about 2 tablespoon of liquid, about 2 to 4 minutes. Remove from heat and let steep for 5 minutes.

  • Set a fine-mesh sieve over a small bowl and strain the mixture, pressing on the solids. You should have about 2 tablespoons of liquid. Let cool slightly.

  • Melt the butter in a small saucepan over low heat. Once fully melted, remove from heat and pour into a pitcher, discarding the solids.
  • Insert an immersion blender into the egg yolk mixture and blend briefly. With the motor running, slowly drizzle in the hot butter and blend until smooth and thick.

  • Chop the remaining tarragon and stir it into the sauce along with a splash of hot water to adjust the consistency, if needed. The sauce should be pourable but not runny.

Notes

Use fresh tarragon if possible: It gives the sauce its signature flavor and brightness. Dried works in a pinch but is less aromatic.
Immersion blender tip: A tall, narrow container helps create a strong vortex for a smooth emulsion.
Make-ahead: The vinegar reduction can be made a day in advance and stored in the fridge.
Reheating: Gently warm the sauce in a bowl set over warm water. Avoid microwaving, which can break the emulsion.
Serving ideas: Spoon over steak, salmon, roasted potatoes, or asparagus. Great in eggs Benedict or steak Oscar.
