Ingredients

  • 1.5 lbs dry-pack sea scallops(side muscles removed, patted thoroughly dry)
  • 4 tbsp unsalted butter(divided)
  • 2 tbsp extra virgin olive oil(divided)
  • 2 medium leeks(white and pale green parts only, thinly sliced into half-moons)
  • 2 medium shallots(finely minced)
  • 2 cloves garlic(finely minced)
  • 0.5 cup dry sparkling wine(such as California Blanc de Blancs or French Crémant)
  • 2 tbsp fresh lemon juice(freshly squeezed)
  • 1 tbsp fresh tarragon(finely chopped)
  • 2 tbsp fresh chives(finely chopped)
  • 1 tsp flaky sea salt(divided)
  • 0.25 tsp freshly cracked black pepper

Instructions

  1. 1

    Pat 1.5 lbs dry-pack sea scallops completely dry with paper towels. Season both sides with 0.5 tsp flaky sea salt and 0.25 tsp freshly cracked black pepper. Thinly slice 2 medium leeks and finely mince 2 medium shallots and 2 cloves garlic.

    10 min

    Tip: Dry scallops are essential! Any surface moisture will steam them instead of creating that gorgeous golden crust.

  2. 2

    In a large skillet, heat 1 tbsp extra virgin olive oil and 2 tbsp unsalted butter over medium-low heat. Add sliced 2 medium leeks with a small pinch of salt and cook slowly, stirring occasionally, until tender, translucent, and sweet, about 8-10 minutes. Transfer the melted leeks to a warm serving platter.

    10 min

    Tip: Take your time with the leeks—letting them sweat gently coaxes out their subtle natural sweetness without scorching.

  3. 3

    In the same hot skillet, add remaining 1 tbsp extra virgin olive oil over medium-high heat until shimmering. Add 1.5 lbs dry-pack sea scallops in a single layer, ensuring they don't touch. Sear undisturbed for 2 minutes until a deep golden crust forms. Flip and sear for 1 to 1.5 minutes more until just opaque. Transfer scallops immediately to the platter over the leeks.

    5 min

    Tip: Don't crowd the pan! If needed, cook in two quick batches so the scallops sear properly rather than steaming.

  4. 4

    Lower heat to medium. Add minced 2 medium shallots and 2 cloves garlic to the residual pan juices, cooking for 1 minute until fragrant. Deglaze with 0.5 cup dry sparkling wine, scraping up all those caramelized bits from the bottom of the pan. Simmer rapidly for 2 minutes until reduced by half.

    4 min

    Tip: The high acidity of sparkling wine cuts right through the sweet richness of the scallops and butter.

  5. 5

    Pour in 2 tbsp fresh lemon juice, then pull the pan off the heat. Immediately swirl in the remaining cold 2 tbsp unsalted butter piece by piece until the sauce becomes silky and glossy. Stir in 1 tbsp fresh tarragon and 2 tbsp fresh chives. Spoon sauce over scallops, finish with 0.5 tsp flaky sea salt, and serve warm.

    3 min

    Tip: Off-heat butter swirling (mounting with butter, or monter au beurre) creates a velvety emulsion without splitting.

Chef's Notes

Always buy 'dry-pack' scallops—wet scallops treated with sodium tripolyphosphate will release water in the pan and prevent browning. Pair this dish with a crisp California Blanc de Blancs or a chilled glass of dry French rosé.
