01 - Turn on oven broiler or preheat to 425°F for toasting bread and warming finished toasts.
02 - In a small bowl, combine softened butter, minced garlic, lemon juice, lemon zest, parsley, chives, salt, pepper, and cayenne. Mix until smooth and fully incorporated.
03 - Gently fold crab meat into garlic butter mixture, taking care not to break up the crab lumps.
04 - Arrange bread slices on a baking sheet. Toast under broiler or in oven for 2-3 minutes per side until golden brown and crisp.
05 - Spoon crab mixture generously onto each toast. Return to oven and broil 1-2 minutes until warmed through. Avoid overcooking to preserve crab texture.
06 - Remove from oven, sprinkle with additional fresh herbs, and serve immediately with lemon wedges on the side.
