King Crab is renowned as one of the largest and most delectable crabs in the culinary world. Since it is pre-processed before freezing, it is incredibly easy to prepare at home. Steaming is the most common method to retain the crab's tenderness and natural flavor. For a zesty twist with lemon and other ingredients, baking in the oven is a great option. Grilling is an excellent way to enhance the crab's rich flavor, especially on warm days. Lastly, boiling is the quickest method to reheat the crab. Enjoy King Crab legs while warm, paired with melted butter, for a truly delightful meal.

Steps

Wash and Thaw the Crab Legs

Thaw the crab legs overnight in the refrigerator before cooking. It takes about 8 hours to thaw King Crab legs. You should only start thawing when you’re ready to cook. For a quicker thaw, place the crab legs under cold running water. Although you can cook crab legs while still frozen, they will cook faster and more evenly if thawed first.

King Crab legs spoil quickly, so avoid thawing them days in advance.
Most crab legs are frozen to preserve freshness. You won’t find many live crabs unless you’re near the ocean. If buying fresh crab, make sure to clean it thoroughly.

Use kitchen shears to cut the crab legs if necessary. Usually, you can place the crab legs whole in a steamer, pot, or baking tray. However, King Crab legs are quite large and may not fit as desired. To handle this, use a sharp tool like kitchen shears, a chef’s knife, or a paring knife to cut the crab legs at the joints and separate them into smaller pieces.

If you can keep the crab legs whole, avoid cutting them. This not only saves effort but also helps retain the crab’s tenderness and sweetness.

Use a knife to score the shell for easier opening. While optional, this step can help you handle the tough outer shell of the crab legs. Flip the crab legs to the underside (the white side) and use a sharp serrated knife to make a shallow cut along the length of the leg. Be careful not to cut into the crab meat.

Don’t remove the shell before cooking. Once cooked, you can open the shell along the scored line. This method makes it easier to access the meat.
Avoid removing the shell entirely or cutting too deep. Exposed crab meat can dry out during cooking. Be cautious not to cut through the shell while scoring.

Steamed Crab Legs

Pour 3 cups (700 ml) of water into a large pot. The water temperature doesn’t matter, but ensure the water only fills about one-third of the pot. Prepare a steamer basket that fits inside the pot but don’t place it in yet. A steamer basket is essentially a small metal rack that sits above the water level to cook food. Make sure the water doesn’t touch the steamer or the crab legs.

If you don’t have a steamer basket, you can use a metal colander as a substitute. Alternatively, you can use a cooling rack or tightly folded aluminum foil placed inside the pot.
The exact amount of water isn’t critical. The key is to ensure there’s enough water to last the steaming process without drying out, but not so much that it submerges the crab.

Add halved lemons and garlic to the water if you want to infuse flavor. While optional, this step enhances the taste of the steamed crab. Cut 3 lemons in half and add them to the water, then peel a bulb of garlic, separate the cloves, and add them to the pot.

You can adjust the amount of lemon and garlic to your preference. Pre-minced garlic or finely chopped garlic can also be used if desired.

Bring the water to a gentle boil over high heat. Heat the water to 100°C. When small bubbles start to form, it’s time to add the crab. This method uses minimal water, so don’t worry if it doesn’t boil vigorously. However, ensure there’s enough water to last for 5 minutes of steaming.

Check the water level one last time. The water should not touch the steamer basket when placed in the pot. If the water level is too high, let it cool slightly and pour some out.

Place the steamer basket and crab legs into the pot. Arrange the crab legs in the steamer basket as flat as possible. You can stack them if necessary, as long as they fit inside the pot. Typically, you can steam about 0.7 kg–1 kg of crab legs at once, depending on the size of your pot and steamer.

If you have more crab legs, consider steaming them in batches. This ensures even steaming and allows all the crab legs to cook uniformly. Overcrowding the pot may result in unevenly cooked crab.

Cover and steam for 5 minutes. Check all the crab legs once the time is up. When done, your kitchen will be filled with the rich aroma of crab. The legs will turn a uniform red color and be evenly heated.

Melt butter if you want to make a dipping sauce for the crab. Making a basic sauce is simple—just melt some butter to dip the crab meat. Melt 1/2 cup (120 g) of butter in a saucepan on the stove. For added flavor, mix in 2 tablespoons (30 ml) of lemon juice and 2 teaspoons of garlic powder. You can drizzle the sauce over the crab or dip the meat directly.

The sauce is optional, as the crab legs are delicious on their own without any seasoning.

Oven-Baked Crab Legs

Preheat the oven to 177°C. Prepare the crab legs while the oven heats up. Allow at least 5-10 minutes for the oven to reach the desired temperature. Keep the oven door closed until you’re ready to place the crab inside.

Pay attention to temperature settings. The heat level will affect the baking time, and higher temperatures can dry out the crab meat.

Arrange the crab legs in a single layer on a shallow baking tray. Choose a wide tray with enough space to lay out the crab legs. Avoid using deep trays, as they can cause uneven cooking. Lay the crab legs flat on the tray. Typically, you can fit up to 1 kg of crab legs on one tray.

If the crab legs don’t fit, consider baking them in batches or using multiple trays. Avoid stacking them, as this will result in uneven cooking.

Boil ½ cup (120 ml) of water and pour it into the baking tray. You can heat the water in a microwave or kettle. Be cautious when pouring to avoid burns. Pour the water directly into the tray so that it forms a thin layer, about 0.3 cm deep. You may need more or less water depending on the size of your baking tray.

Wear oven mitts or rubber kitchen gloves to protect yourself from hot water.
Adding water to the tray is optional, but it helps keep the crab moist during baking. Without water, the crab meat may become dry and tough.

Mix lemon juice, garlic, and other seasonings to flavor the crab. One advantage of baking is the ability to add a variety of ingredients. For a simple recipe, combine ¼ cup (60 ml) of lemon juice, 3 tablespoons (45 ml) of olive oil, ¾ cup (170 g) of butter, 3 garlic cloves, and 1 teaspoon of parsley in a separate bowl.

Feel free to adjust the seasoning to your taste. For example, you can add salt, Cajun seasoning, or herbs like dill. If you prefer the natural flavor of crab, you can skip this step entirely.

Use a brush or drizzle the seasoning mixture over the crab legs if desired. Use a kitchen brush to coat all the crab legs evenly with the mixture. If you don’t have a brush, you can pour the mixture over the tray, ensuring it spreads evenly across the crab legs.

Consider saving half of the butter sauce to serve with the crab after baking. This step is optional but adds extra flavor to the dish.

Cover the tray with aluminum foil. Use the foil to trap moisture and flavor inside the tray. Seal the tray tightly, folding the edges of the foil over the sides. Be careful when placing the tray in the oven to avoid spilling the water.

This step ensures the crab stays juicy and flavorful during baking.

Bake the crab in the oven for about 15 minutes. Set a timer and wait. When the time is up, remove the foil to check the crab. The legs should turn a vibrant red color when fully cooked. You can touch them to ensure they’re evenly heated. The aroma of the crab will fill your kitchen.

Note that baking times may vary depending on your oven type and heat settings.

Using a Grill

Preheat the grill to around 163°C. Use a medium-low heat setting if your grill has adjustable temperature controls. Allow 15 minutes for the grill to reach the appropriate temperature. You can prepare the crab legs while waiting for the grill to heat up.

If your grill has limited temperature settings, use a medium heat level. Keep a close eye on the crab to prevent overcooking.

Brush oil onto the crab legs if you plan to place them directly on the grill. Pour about ¼ cup (60 ml) of olive oil into a bowl. Use a kitchen brush to coat the crab legs evenly with oil. This will prevent the crab from sticking to the grill.

If you don’t have a brush, you can use your hands to rub the oil onto the crab legs or roll them in the oil.
Alternatively, you can wrap the crab legs in aluminum foil. This is a safe way to grill and prevents sticking. If you plan to season the crab before grilling, use foil instead of oil.

Wrap the crab legs in foil if you plan to season them. Lay out 4 sheets of aluminum foil on the kitchen counter and evenly distribute the crab legs on top. Typically, you can wrap about 1.5 kg of crab legs, so use additional foil if needed. Take 4 more sheets of foil to cover the crab legs.

You don’t need to use foil if you’re grilling the crab without seasoning. Simply brush oil to prevent sticking.

Spread butter and seasonings over the crab to enhance the flavor. For example, use 1/4 cup (55 g) of butter and rub it onto the crab legs with your hands. Then, cut a lemon into quarters and squeeze the juice over the crab.

To add more flavor, mince 5 garlic cloves and sprinkle them over the crab. Add 1/2 cup of parsley, 1 teaspoon of sea salt, and 1 teaspoon of black pepper.
You can also melt some butter and drizzle it over the crab after grilling.

Grill the crab legs for about 5 minutes. Place the crab legs near the edge of the grill, avoiding direct heat or hot coals to prevent overcooking. Keep the crab legs about 13 cm away from the heat source, close the grill lid, and let them cook.

If grilling the crab legs in foil, ensure they are tightly sealed to retain the seasoning. Butter and other seasonings will be wasted if they leak out!

Flip the crab legs and grill for another 5 minutes. Use tongs to turn the crab legs, keeping them in the same position. Close the grill lid after flipping. When done, the crab legs will turn a vibrant red and emit a rich crab aroma. The entire crab legs will be evenly heated.

Note that grilling times may vary significantly depending on the grill and heat settings. Each grill operates differently, so keep an eye on the crab legs to avoid burning.

Boiled Crab Legs

Fill a large stockpot halfway with cold water. The amount of water needed depends on the size of your pot. An average stockpot can hold about 6 liters of water, but adjust as necessary. This amount is sufficient to boil 1.8 kg of crab legs.

Ensure the crab legs are fully submerged; otherwise, they may cook unevenly. If the pot is too small, you’ll need to boil them in batches or use multiple pots.

Season the water with salt or spices if you want more flavorful crab. For example, start by dissolving 1 tablespoon of salt in the water, then add 2 tablespoons of seafood seasoning. You can also mix in herbs like parsley or dill, add garlic and lemon to the pot, or include any other ingredients you prefer.

Salt is essential for boiling crab legs and helps them cook more evenly. Even if you skip other seasonings, don’t forget to add salt.

Turn the heat to high until the water begins to boil. Set the heat to high and wait for the water to boil. Watch for continuous bubbling. It may take some time, so don’t rush to lower the heat.

The water must be boiling when you add the crab. If the water isn’t boiling, it will be difficult to determine when the crab is fully cooked.

Submerge the crab legs in the water. Carefully place the crab legs into the boiling water, avoiding splashes. Use tongs to press the crab legs down as much as possible. Arrange them so they are fully submerged before cooking.

Parts not submerged won’t cook evenly. For consistent results, ensure the crab legs are completely covered.
If the pot is too small, boil the crab legs in batches.

Reduce the heat to medium and wait for the water to return to a boil. When the crab legs are added, the water temperature will drop, and bubbling will stop. Wait a few minutes until the water starts bubbling rapidly again. At this point, the water will cook the crab legs quickly and evenly.

Maintain a gentle simmer until the crab is cooked. Look for small, steady bubbles and steam. Set a timer once the water reaches this stage.

Boil the crab for 5-7 minutes until fully cooked. Keep the lid off while boiling and watch for the crab legs to change color. They will turn a vibrant red, and the rich aroma of crab will fill the kitchen. Once done, use tongs to remove the crab legs and serve them warm.

Serve the crab legs hot with melted butter and lemon juice. You can also enjoy them plain if preferred.

Tips

King Crab legs are typically pre-cooked, so you mostly just need to reheat them at home. Check the crab when the timer goes off to avoid overcooking!
You don’t need to season the crab meat after cooking, but it pairs wonderfully with melted butter.
