  • 2 tablespoons unsalted butter
  • 2 cloves garlic smashed
  • 3 sprigs fresh thyme
  • Fleur de sel or Maldon sea salt for finishing
For the Brown Butter and Garnish
  • 3 tablespoons unsalted butter
  • 1 tablespoon fresh lemon juice
  • 1 tablespoon fresh chives finely sliced
  • 1 tablespoon micro greens or pea shoots optional

  • High-powered blender or food processor
  • Fine-mesh strainer
  • Paper towels
  • Instant-read thermometer
  • Fish spatula

Method
 

Prepare the Parsnip Purée
  1. Place peeled and cut parsnips in a medium saucepan. Add milk and enough water to just cover the parsnips. Add 1 teaspoon kosher salt.
  2. Bring to a simmer over medium heat, then reduce heat to maintain a gentle simmer. Cook until parsnips are completely tender when pierced with a knife, approximately 20-25 minutes.
  3. Drain parsnips, reserving 1/2 cup of the cooking liquid. Transfer parsnips to a high-powered blender.
  4. Add heavy cream and blend on high until completely smooth, about 2 minutes. With the blender running, add cold butter one cube at a time until fully incorporated and silky.
  5. Pass the purée through a fine-mesh strainer for ultimate smoothness. Season with white pepper and nutmeg. Adjust salt to taste. Keep warm, covered, until ready to serve.
Prepare the Scallops
  1. Remove the small side muscle from each scallop if still attached. Pat scallops thoroughly dry with paper towels on all sides. This step is critical for achieving a proper sear.
  2. Place scallops on a paper towel-lined plate, uncovered, and refrigerate for 15-20 minutes to further dry the surface. Remove from refrigerator 5 minutes before cooking.
  3. Season scallops on both flat sides with a light, even coating of kosher salt immediately before cooking.
Sear the Scallops
  1. Heat a 12-inch stainless steel or cast iron skillet over high heat until very hot, about 2-3 minutes. The pan should be just beginning to smoke.
  2. Add high-heat oil to the pan, swirling to coat. The oil should shimmer immediately and show wisps of smoke.
  3. Carefully place scallops in the pan, flat side down, leaving at least 1 inch between each. Do not move them once placed. Work in batches if necessary to avoid crowding.
  4. Sear without moving for 2 minutes. A deep golden-brown crust should form. If the scallop releases easily from the pan, it is ready to flip. If it sticks, give it another 15-30 seconds.
  5. Flip scallops using a fish spatula. Add butter, smashed garlic, and thyme sprigs to the pan. Tilt the pan and baste scallops with the foaming butter for 1-1.5 minutes.
  6. Remove scallops when the center reaches 115-120°F for medium-rare, or 125°F for medium. The center should be slightly translucent. Transfer to a warm plate to rest.
Make the Brown Butter Sauce
  1. Wipe out the skillet and return to medium heat. Add 3 tablespoons butter and cook, swirling occasionally, until the milk solids turn golden brown and smell nutty, about 2-3 minutes.
  2. Remove from heat immediately and add lemon juice. The butter will foam vigorously. Swirl to combine.
Plate and Serve
  1. Spoon a generous mound of warm parsnip purée onto the center of each warmed plate. Use the back of the spoon to create a shallow well or swoosh.
  2. Arrange 3 scallops per plate, seared side up, atop the purée. Drizzle with brown butter sauce.
  3. Garnish with sliced chives and micro greens if using. Finish with a few flakes of fleur de sel. Serve immediately.

Notes

Dry-packed scallops are essential. Wet-packed scallops contain sodium tripolyphosphate, which causes them to absorb water and prevents proper browning. Look for scallops labeled "dry" or "dry-packed" at quality seafood counters.
U-10 refers to scallop size, meaning fewer than 10 scallops per pound. These large scallops are ideal for searing as they develop a beautiful crust while remaining tender inside.
The parsnip purée can be made up to 2 days ahead and gently reheated with a splash of cream. The scallops must be cooked just before serving.
For an elegant variation, add a drizzle of aged balsamic reduction or truffle oil before serving.
