Ingredients
1/4 cup mayonnaise
2 tablespoons fresh lemon juice, plus lemon wedges for serving
Kosher salt
1/4 teaspoon Old Bay seasoning, plus more for serving
1/8 teaspoon cayenne pepper
1 pound jumbo lump crabmeat, drained and picked over
6 tablespoons melted unsalted butter
6 top-split buns
1 head butter lettuce (such as Boston), leaves separated, for serving
Chopped fresh chives and potato chips, for serving
Preparation
In a medium bowl, whisk together mayonnaise, lemon juice, 1 teaspoon salt, Old Bay, and cayenne. Gently fold in crabmeat.
Heat a large skillet (preferably cast iron) over medium, about 8 minutes. Generously brush top and sides of buns with butter. Place buns, flat-side down, in skillet and toast, flipping halfway through, until crisp and golden on both sides, about 3 minutes. Line inside of buns with 1 to 2 lettuce leaves; divide crabmeat among buns. Drizzle tops with remaining melted butter; sprinkle with chives and more Old Bay. Serve, with lemon wedges and potato chips.
