Prep & Cooking Time

Ingredients You Will Need

For the Crab Legs:

• 2 lbs Snow Crab Legs or King Crab Legs: Thawed if frozen, separated into clusters.
• 2 cups Water or Low-Sodium Chicken Broth: For the steaming pot.
• 1 Lemon (Sliced into rounds): Added to the steaming liquid.

For the Garlic Butter Drench:

• 1/2 cup (1 stick) Unsalted Butter: Melted to rich perfection.
• 5 Cloves Fresh Garlic: Minced or pressed finely.
• 1 tbsp Fresh Lemon Juice: Squeezed fresh.
• 1 tbsp Fresh Italian Parsley: Finely chopped.
• 1/2 tsp Old Bay Seasoning (or Cajun Seasoning): Adds classic seafood warmth.
• 1/4 tsp Red Pepper Flakes: For an optional touch of heat.

Step-by-Step Instructions

1. Thaw and Prep: If using frozen crab legs, thaw them completely in the refrigerator overnight or submerge them in cold water for 30 minutes. Rinse and pat dry.
2. Set Up the Steamer: Place a steamer basket inside a large pot or Dutch oven. Pour in 2 cups of water or broth, add lemon slices, and bring to a rolling boil over high heat.
3. Steam the Crab Legs: Arrange the crab clusters inside the steamer basket. Cover with a tight-fitting lid and steam for 5 to 7 minutes until the crab meat is piping hot throughout.
4. Make the Garlic Butter Sauce: While the crab steams, melt the unsalted butter in a small saucepan over medium-low heat. Add minced garlic and sauté for 1 minute until fragrant (do not let it burn).
5. Add Seasoning and Citrus: Stir in Old Bay seasoning, fresh lemon juice, chopped parsley, and red pepper flakes. Simmer gently for 1 minute, then remove from heat.
6. Serve and Drench: Transfer the hot Garlic Butter Crab Legs to a large serving platter or board. Pour the warm garlic butter sauce generously over the top or serve in individual bowls for dipping!

Chef’s Note: Most store-bought crab legs are flash-frozen and pre-cooked during processing. Do not boil them for a long time; simply steam or warm them briefly so the meat stays tender, juicy, and sweet.

Frequently Asked Questions

Can I bake the crab legs instead of steaming?

Yes! Place thawed crab legs on a foil-lined baking sheet, brush with melted garlic butter, cover tightly with foil, and bake at 375°F (190°C) for 12 to 15 minutes.

Should I thaw frozen crab legs before cooking?

Yes, thawing them ensures they heat evenly and prevents excess water from diluting your steamer and butter sauce.
