Pan-Seared Day-Boat Scallops with Melted Leeks & Sparkling Wine Pan Sauce
There is something utterly magical about day-boat scallops. I remember standing at the Santa Monica Farmers Market last spring, chatting with my favorite fisherman, Mateo, who handed me a batch of scallops so fresh they practically whispered the ocean. That afternoon, I wanted something that felt like a breezy Parisian bistro but leaned into our glorious California sunshine. Enter this dish. Melted leeks are one of my absolute kitchen secrets—cook them down low and slow in a mountain of good butter until they turn sweet and silky. Then, you sear the scallops hard and fast to get that gorgeous golden crust. The real magic happens when you splash a bit of crisp, chilled pet-nat into the pan, letting it bubble up with all those delicious brown bits before swirling in a final pat of butter. It is sophisticated, yes, but remarkably fuss-free. My biggest tip? Don't crowd the pan, and please, open a second bottle of that sparkling wine to sip while you cook. After all, a little bubbly makes everything taste better.

Timeline
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
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
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.

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.

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
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.

French soul, California sun
I grew up in a small village outside Lyon, where my grandmother taught me that the best meals come from respecting your ingredients. After training at Le Cordon Bleu and spending years in Parisian kitchens, I moved to San Francisco and fell in love with California's farmers markets and wine country. Now I cook the food I wish my grandmother could taste—French technique with California abundance, where a perfect roast chicken might come with Meyer lemon and wild fennel instead of tarragon.
