Directions
Prepare the Crab Legs
If using frozen crab legs, thaw them overnight in the refrigerator or under cold running water. Using kitchen scissors or a sharp knife, cut along the top of the crab shells to make them easier to access.
Cook the Crab Legs
Bring a large pot of salted water to a boil. Add the crab legs and cook for 5–7 minutes until heated through. Drain and set aside.
Make the Garlic Butter Sauce
In a small saucepan over medium heat, melt the butter. Add minced garlic and cook for 1–2 minutes until fragrant but not browned. Stir in lemon juice, Old Bay seasoning (if using), chopped parsley, salt, and pepper. Simmer for an additional minute.
Serve
Arrange crab legs on a serving platter. Drizzle generously with garlic butter sauce, ensuring each piece is coated. Garnish with extra parsley and serve with lemon wedges.
