Classic béarnaise is already a beautiful thing, but this version layers in the subtle anise sweetness of fresh fennel for a sauce that feels both familiar and quietly special. The reduction starts with white grape juice and water instead of wine, coaxing all that aromatic depth from the tarragon stems and finely chopped fennel before they're strained away entirely. What's left is a clean, fragrant base that carries the richness of the butter and egg yolks without any heaviness. Because the ingredient list is built entirely around eggs, butter, fresh herbs, and a simple reduction, there's nothing here that sneaks in a legume derivative — no hidden soy lecithin, no bean-based thickeners, just honest classical technique. The double-boiler method and the step-by-step butter incorporation are what make the texture silky and stable rather than greasy or broken. Spoon it over grilled steak, roasted asparagus, or poached fish and it will absolutely steal the show.

Ingredients

4 servings

For the reduction

3 tbsp white grape juice
3 tbsp water
1 tbsp fresh tarragon stems, roughly chopped
2 tbsp fennel bulb, finely chopped

For the sauce

3 pasteurized egg yolks
½ cup unsalted butter, cut into 1-tbsp pieces
¼ tsp salt
2 tbsp fresh tarragon leaves, finely chopped

Instructions

1
Combine the white grape juice, water, chopped tarragon stems, and fennel in a small saucepan over medium heat. Bring to a simmer and cook until the liquid reduces to about 2 tablespoons, 5–7 minutes. Pour through a fine-mesh strainer into a heatproof bowl, pressing the solids to extract all the liquid; discard the solids.
2
Add the pasteurized egg yolks to the strained reduction in the heatproof bowl and whisk until the mixture is smooth and slightly thickened.
