Steamed King Crab Legs with Garlic Lemon Butter

Why You’ll Love This Recipe

I love this recipe because it is incredibly quick and easy to prepare. Since king crab legs are typically pre-cooked, I only need to gently steam them until heated through. The garlic lemon butter adds a bright, savory flavor that complements the natural sweetness of the crab without overpowering it. I also appreciate that this dish feels restaurant-quality while using just a handful of ingredients.

Ingredients

(Here’s a tip: Check out the full list of ingredients and measurements in the recipe card below.)

2 pounds king crab legs (fresh or frozen, pre-cooked)

2 cups water

1 lemon, sliced

1 teaspoon Old Bay seasoning (optional)

½ cup unsalted butter

3 garlic cloves, minced

1 tablespoon fresh lemon juice

1 teaspoon lemon zest

1 tablespoon fresh parsley, chopped

Pinch of cayenne or paprika (optional)

Salt, to taste

Directions

I rinse the crab legs under cool running water to remove any ice and separate the legs.

I use kitchen shears to cut the crab legs into smaller sections so they fit comfortably in the steamer basket.

I fill a large pot with 2 cups of water and 1 cup of white wine, or additional water if I prefer.

I add the lemon slices and Old Bay seasoning to the steaming liquid.

I place a steamer basket or metal colander above the water line, making sure it does not touch the liquid.

I bring the liquid to a rolling boil over medium-high heat.

I add the crab legs to the steamer basket, cover the pot, and steam for 6 to 8 minutes if thawed or 8 to 10 minutes if frozen.

While the crab steams, I melt the butter in a small saucepan over low heat.

I add the minced garlic and cook for about 30 to 45 seconds until fragrant.

I stir in the lemon juice, lemon zest, parsley, cayenne or paprika, and a pinch of salt.

I transfer the steamed crab legs to a serving platter, brush them lightly with the garlic lemon butter, and serve with extra butter and lemon wedges.

Servings and Timing

This recipe makes 2 servings.

Preparation time: 5 minutes

Cooking time: 10 minutes

Total time: 15 minutes

Variations

I add a splash of white wine to the butter sauce for extra depth of flavor.

I substitute fresh dill or chives for the parsley when I want a different herb profile.

I increase the cayenne pepper for a spicier version.

I serve the crab with drawn butter only when I want to highlight the natural sweetness of the meat.

I add a sprinkle of grated Parmesan to the butter sauce for a richer finish.

Storage/Reheating

I store leftover crab legs in an airtight container in the refrigerator for up to 2 days.

To reheat, I steam the crab legs for 3 to 5 minutes until warmed through. I avoid overheating because it can make the meat tough.

I store any leftover garlic lemon butter separately in the refrigerator for up to 5 days and gently reheat it before serving.

Freezing is not recommended after reheating, as the texture of the crab may suffer.
