This classic, creamy butter-tarragon sauce is fancy, but effortless thanks to this simplified blender preparation. Be sure the butter is hot when you add it to the blender; adequate heat allows the butter to cook the eggs as they blend together.
Ingredients List
- 1/4 cup Champagne or white wine vinegar
- 1/4 cup dry white wine, such as sauvignon blanc or pinot grigio
- 1 shallot, minced
- 2 Tbsp chopped fresh tarragon, plus a bit more for garnish
- sea salt and freshly ground pepper
- 4 large egg yolks
- 2 sticks (8 oz) butter, melted and hot
Instructions
- In a small saucepan, combine the vinegar, white wine, shallot, 1 tablespoon of the tarragon, 1/4 teaspoon salt and 1/4 teaspoon pepper. Bring to a boil and lower to a simmer over medium heat until the mixture is reduced to a few tablespoons, about 5 minutes. Cool slightly.
- Transfer the cooled mixture to a blender and add the egg yolks and 1 teaspoon salt. Blend for 30 seconds. With the blender on, slowly pour the hot melted butter through the opening in the lid. Add the remaining tarragon leaves and pulse for a few times.
- If the sauce is too thick, add a tablespoon of water to thin. Garnish with a little chopped tarragon and serve immediately.

Thank you for allowing me to access them.
I’ve made bernaise and hollandaise sauce many times the Julia Child’s way, but not in that quantity. It would behelpful to know how long it keeps and how to reheat it,
Hi Bob – It’s best to serve Bearnaise sauce immediately, but if you have extra you can store it in the fridge and reheat it in a double boiler and whisk before serving.
Storing Bernaise or hollandaise in a thermos is a great way to make it many hours before needed and it stays warm and perfect.
I am abstaining from alcohol & won’t even go in a liquor store. Is there something else I could use for the wine?
Hi Lisa – we suggest you make the hollandaise sauce instead which does not have any alcohol, and add tarragon to it.
Thank you for asking this question. I’m allergic to wine sulfates and was wondering the same.
