Create a sophisticated and tender vegetable side dish by slow-braising leeks and finishing them with a light, classic white wine butter sauce. This recipe delivers gourmet results with simple steps.

Ingredients

Scale
  • 4 large leeks, white and light green parts only
  • 2 tablespoons unsalted butter
  • 1 tablespoon olive oil
  • 1 shallot, finely minced
  • 1/2 cup dry white wine (like Sauvignon Blanc)
  • 1/2 cup low-sodium chicken or vegetable broth
  • 1/4 cup heavy cream
  • 2 tablespoons cold unsalted butter, cut into small cubes
  • 1 teaspoon Dijon mustard
  • Salt and freshly ground black pepper to taste
  • Fresh parsley, chopped, for garnish

Instructions

  1. Prepare the leeks: Trim the root ends and the dark green tops. Slice the white and light green parts lengthwise and rinse thoroughly under cold water to remove all grit. Cut the leeks into 2-inch pieces.
  2. Sauté aromatics: In a large, heavy-bottomed pot or Dutch oven, melt 2 tablespoons of butter with the olive oil over medium heat. Add the minced shallot and cook until softened, about 2 minutes.
  3. Braise the leeks: Add the prepared leek pieces to the pot. Season lightly with salt and pepper. Cook, stirring occasionally, for 5 minutes until the leeks begin to soften slightly.
  4. Deglaze and simmer: Pour in the white wine and let it bubble and reduce by half, scraping up any browned bits from the bottom of the pot. Add the broth. Bring the liquid to a gentle simmer, cover the pot, and reduce the heat to low. Cook for 20 to 25 minutes, or until the leeks are very tender.
  5. Prepare the beurre blanc: Carefully remove the tender leeks from the pot using a slotted spoon and set them aside in a warm bowl. Keep the remaining cooking liquid in the pot.
  6. Reduce the sauce base: Bring the liquid in the pot to a steady simmer over medium heat. Let it reduce until you have about 1/4 cup of concentrated liquid remaining.
  7. Emulsify the sauce: Reduce the heat to low. Whisk in the Dijon mustard. Gradually whisk in the cold butter cubes, one or two at a time, allowing each piece to incorporate fully before adding the next. Do not let the sauce boil; it should remain creamy and emulsified.
  8. Finish the sauce: Stir in the heavy cream. Taste the sauce and adjust seasoning with salt and pepper. If the sauce is too thick, add a teaspoon of warm water.
  9. Serve: Gently return the braised leeks to the sauce just to coat them, or spoon the sauce generously over the leeks in a serving dish. Garnish with fresh parsley. Serve immediately as an elegant side dish.

Notes

  • For a vegan braised leeks side, substitute the butter with olive oil or vegan butter blocks, use vegetable broth, and replace the cream and butter in the sauce with a plant-based cream alternative and a vegan butter substitute, ensuring the sauce emulsifies correctly.
  • To clean leeks properly, soak the cut pieces in a bowl of water; the grit will sink to the bottom. Lift the leeks out gently.
  • This dish pairs well with roasted chicken or pan-seared fish.
