Step-by-Step Cooking Instructions
Method 1: Steaming (Best for Flavor and Texture)
-
Thaw crab legs (optional): If time permits, thaw in the refrigerator overnight.
-
Set up steamer: Add 1–2 inches of water in a large pot and place a steamer basket.
-
Season water: Toss in lemon wedges and Old Bay into the water.
-
Steam crab legs: Place frozen crab legs in the basket, cover, and steam for 7–10 minutes until heated through.
-
Serve with garlic butter: Melt butter in a pan, add garlic, and serve on the side or drizzle over the crab.
Method 2: Boiling (Fast and Easy)
-
Boil water: Fill a large pot with water, add salt or seasoning, and bring to a boil.
-
Add crab legs: Submerge frozen crab legs and cook for 5–6 minutes.
-
Drain and serve: Use tongs to remove and serve with melted butter and lemon.
Method 3: Oven Baking

Common Mistakes to Avoid
-
Overcooking: Crab legs are already cooked—just reheat!
