Melt the butter and minced garlic together in a small pan and keep warm on its lowest setting.
Set a steamer tray inside a large pot and pour enough water inside to steam the crab. You are only reheating the crab, so you will only need a couple inches of water.
Add a few cloves of garlic to the water, if desired.
Bring water to a boil before laying the crab legs on the steamer. Cover the pot and steam for 5 minutes.
Remove the crab legs and serve with melted garlic butter and lemon wedges. Enjoy!!!
