Melt 4 tablespoons butter in a cast-iron or ovenproof skillet. Stir in wine and next 5 ingredients. Add scallops, turning to coat. Remove from heat.
Melt remaining 1 tablespoon butter in a small bowl in the microwave, and stir in panko and nuts. Sprinkle mixture over scallops. Bake at 375° for 10 to 12 minutes or until bubbly and golden brown. Serve with hot cooked pasta. Garnish, if desired.
