Ingredients
For the king crab legs
– 2–3 pounds (900 g–1.4 kg) king crab legs, thawed if frozen
– 1 lemon, cut into wedges
– 1 cup water, for steaming
– 2 lemon slices, optional
– 2 tablespoons fresh parsley, finely chopped
For the garlic butter sauce
– ½ cup (115 g) unsalted butter
– 6 cloves garlic, finely minced
– 1 tablespoon fresh lemon juice
– 1 teaspoon lemon zest
– ½ teaspoon paprika
– ¼ teaspoon red pepper flakes, optional
– ½ teaspoon freshly ground black pepper
– ¼ teaspoon salt, or to taste
– 1 tablespoon fresh parsley, chopped
– 1 teaspoon olive oil, optional
Instructions
1. Thaw and prepare the crab legs
If the crab legs are frozen, thaw them overnight in the refrigerator. For a quicker method, place them in a sealed bag under cold running water until thawed.
Rinse briefly under cold water and pat dry. Use kitchen scissors to cut lengthwise along the shells where practical, making the meat easier to access after cooking.
Most king crab legs sold commercially are already cooked, so the goal is to heat them thoroughly without drying out the delicate meat.
2. Steam the crab legs
Place a steamer basket inside a large pot and add about 1 cup of water. Make sure the water level stays below the basket.
Bring the water to a boil. Arrange the crab legs in the basket, cover tightly, and steam until hot throughout.
– Thawed, precooked crab legs: approximately 5–7 minutes.
– Frozen, precooked crab legs: approximately 8–10 minutes, depending on size.
Avoid steaming longer than necessary, as overcooking can make the meat tough. If the package gives specific reheating instructions, follow those directions.
3. Melt the butter
While the crab heats, place a small saucepan over low heat. Add the butter and allow it to melt gently.
If using olive oil, stir it in now. Keep the heat low to prevent the butter from browning too quickly.
4. Add the garlic
Add the minced garlic to the melted butter. Cook for about 30–60 seconds, stirring continuously, until fragrant.
Do not let the garlic turn dark brown, as burnt garlic can taste bitter.
5. Season the sauce
Stir in the lemon juice, lemon zest, paprika, black pepper, and red pepper flakes if using.
Add the salt gradually, tasting before adding more because crab meat can already be naturally salty.
Stir in the chopped parsley and remove the saucepan from the heat.
6. Coat the crab legs
Transfer the hot crab legs to a large serving platter. Spoon some of the garlic butter over the shells and exposed meat.
For extra flavor, carefully open the pre-cut shells and drizzle a little butter directly onto the crab meat.
Reserve the remaining sauce in small dipping bowls.
7. Garnish and serve
Sprinkle with fresh parsley and arrange lemon wedges around the platter.
Serve immediately while the crab is hot, accompanied by warm garlic butter for dipping.

Helpful Tips for the Best Garlic Butter King Crab Legs
– Use fresh garlic: Freshly minced garlic gives the butter a more aromatic, savory flavor.
– Avoid overcooking: Commercial king crab legs are generally precooked, so they only need reheating.
– Add lemon at the end: Fresh lemon juice brightens the buttery sauce without overpowering the sweet crab meat.
– Cut the shells carefully: Kitchen shears make it easier to access the meat without shredding it.
– Save the dipping butter: Serve extra sauce on the side so everyone can add as much as they like.
– Choose unsalted butter: This gives you better control over the final seasoning.
Delicious Variations

Storage and Reheating
– Refrigerator: Store leftover crab meat in an airtight container and refrigerate within 2 hours. Use within 3–4 days.
– Reheating: Gently steam the crab until heated through, or warm the meat in a covered pan over low heat with a splash of water or butter.
– Freezing: Freeze leftover cooked crab meat in a tightly sealed, freezer-safe container for best quality for up to 2–3 months.
– Food safety: Reheat leftovers to 165°F (74°C). Avoid repeatedly reheating the same portion.
Frequently Asked Questions
Are king crab legs already cooked when purchased?
Most commercially sold king crab legs are precooked before freezing. Check the package instructions, and reheat them gently rather than cooking them for an extended period.
Can I bake king crab legs instead of steaming them?
Yes. Place the legs in a baking dish with a splash of water, cover tightly with foil, and bake at 375°F (190°C) for approximately 10–15 minutes if thawed. Adjust the time according to their size and package directions.
Can I make the garlic butter ahead of time?
Yes. Prepare the sauce a day in advance, refrigerate it in a covered container, and gently reheat it over low heat before serving.
How can I tell when the crab is hot enough?
The meat should be hot throughout and steaming when opened. Use a food thermometer where practical, particularly when reheating leftovers.
Can I use snow crab legs instead?
Absolutely. Snow crab legs are smaller and generally need less reheating time, so check them earlier to prevent drying out.
Why is my crab meat tough?
The most common reason is overheating. Since most king crab legs are already cooked, use gentle heat and stop as soon as the meat is thoroughly hot.
Final Serving Idea
Arrange the glossy crab legs on a large platter with golden garlic butter, fresh parsley, and bright lemon wedges. Serve with warm dipping sauce and your favorite sides for an impressive seafood dinner that feels like a restaurant-quality feast at home.
