Plan on serving 1 lb of crab legs per person. If you’re serving a larger group, this recipe is easy to double or even triple, but don’t crowd the stockpot; cook the crab legs in batches.
Frozen crab legs are typically precooked, so you’re simply reheating them in the boiling water. Be careful not to overcook them, as they will lose their delicate flavor.
Add some finely chopped garlic to the melted butter for extra flavor.
