- 3 mediumyellow onions(sliced into thin rings)
- 4 tablespoonsbutter(divided)
- 2fresh lemon(zested and juiced)
- 3garlic cloves(minced)
- 118¼ mldry white wine
- 3 sprigsfresh thyme
- 2 tablespoonsextra virgin olive oil
- 1 teaspoonkosher salt
- ½ teaspoonblack pepper
- 1 tablespoonvegetable oil(for grill)
Instructions
- 1
Heat 2 tablespoons of butter in a large skillet over medium heat. Add sliced onions and cook for 15-18 minutes, stirring occasionally, until golden brown and caramelized. Season with a pinch of salt and set aside.
Tip: Low and slow is key—resist the urge to increase heat, as this develops the natural sweetness of the onions.
- 2
While onions cook, pat scallops completely dry with paper towels and season both sides with kosher salt and black pepper about 10 minutes before grilling.
Tip: Dry scallops are essential for achieving a proper sear and preventing them from steaming on the grill.
- 3
Preheat your grill to high heat. Lightly oil the grates with vegetable oil using a paper towel held with tongs.
Tip: A well-oiled grill prevents sticking and creates beautiful caramelization marks.
- 4
Place scallops on the grill in a single layer without moving them. Grill for 3-4 minutes on the first side until they develop a golden crust.
Tip: Resist the temptation to flip or move the scallops—let them sit undisturbed for optimal browning.
- 5
Flip scallops carefully and grill for another 2-3 minutes on the second side until cooked through. Transfer to a plate.
Tip: Scallops cook quickly; overcooked scallops become rubbery, so watch them closely.
- 6
In a small saucepan, melt the remaining 2 tablespoons of butter over medium heat. Add minced garlic and cook for 30 seconds until fragrant.
Tip: Watch the garlic carefully to prevent burning, which would create a bitter flavor.
- 7
Pour in the white wine and add the fresh thyme sprigs. Simmer for 2 minutes to reduce slightly, then remove from heat.
Tip: The wine adds acidity and depth that complements the sweet caramelized onions.
- 8
Stir in the lemon zest and lemon juice, then season the sauce with salt and pepper to taste.
Tip: Taste as you go—adjust lemon juice to your preference for brightness.
- 9
Plate the grilled scallops and top with a generous spoonful of caramelized onions. Drizzle with the lemon butter sauce and garnish with fresh thyme if desired.
Tip: Serve immediately while the scallops are still warm for the best flavor and texture.
