This classic French Lemon Beurre Blanc is a smooth, delicate butter sauce that is perfect on top of seafood or chicken.

Ingredients

  • 9 Tbsp unsalted butter divided, cold, cubed
  • 1 medium shallot finely chopped
  • ½ cup dry white wine
  • 2 Tbsp white wine vinegar
  • 2 Tbsp fresh lemon juice about ½ large lemon
  • 2 Tbsp heavy cream
  • Kosher salt to taste

Instructions

  • Sweat the shallot. Heat 1 Tbsp butter in a nonreactive saucepan over medium heat. Add minced shallot and cook until translucent, about 2-3 minutes.
  • Add liquid. Pour in ½ cup white wine, 2 Tbsp white wine vinegar, and 2 Tbsp fresh lemon juice. Cook over medium-high heat till the mixture reaches a simmer. Reduce temperature to medium, then let the sauce thicken and reduce, about 4 minutes. Add the heavy cream, stir, then turn the heat down to low.
  • Emulsify with butter. Add 2-3 Tbsp of cold, cubed butter. Swirl the pan (or whisk) until the butter has emulsified into the sauce. Repeat with remaining butter. Taste, then season with a pinch or two of Kosher salt, as needed. Serve immediately.

Notes

  • Leftovers: When stabilized with heavy cream, beurre blanc will last for up to 3 days in a fridge. While beurre blanc can technically be frozen for up to 1 month, it just won't have the same smooth consistency when thawed. I recommend enjoying it fresh.
