01 - Turn on your oven broiler or set oven to 425°F for optimal toasting temperature.
02 - Combine softened butter, minced garlic, lemon juice, lemon zest, parsley, chives, salt, black pepper, and cayenne in a small bowl. Mix thoroughly until completely smooth and well incorporated.
03 - Gently fold the crab meat into the garlic butter mixture using a light touch to preserve the lump texture of the crab.
04 - Arrange bread slices on a baking sheet in a single layer. Broil or bake for 2–3 minutes per side until golden brown and thoroughly crisp.
05 - Spoon the crab mixture generously onto each toast. Return to the oven and broil for 1–2 minutes until heated through, being careful not to overcook the crab.
06 - Remove from oven, sprinkle with additional fresh herbs, and finish with fresh lemon juice. Serve immediately alongside lemon wedges.
