Ingredients for the Best King Crab Legs Recipe

For the best king crab legs recipe, make sure you use high-quality ingredients. One low-quality ingredient can mess up the whole dish! The ingredients you’ll need are:

2 lb. of king crab legs
½ cup of butter (unsalted and melted)

In the US, getting fresh king crab legs is rare. Since the king crab season runs through fall and winter, you’re more likely to find fresh king crab (not frozen) from October to November.

Regardless of the king crab season, pre-cooked flash-frozen king crab legs are available throughout the year. Since these are frozen immediately after harvest, the flavor is retained.

Optional Flavor Enhancers

For more flavor, elevate the king crab legs experience by adding:

3 cloves of garlic (minced)
1 tbsp. of lemon juice (fresh)
1 tsp. of seasoning mix – Old Bay or Cajun, that’s up to you

King Crab Leg Preparation Before Cooking

For a king crab leg preparation, if you’re using frozen king crab legs, thaw them overnight in a refrigerator. If you’re in a hurry, submerge them in the cold water for about 30 to 45 minutes. Besides, since the crab legs were frozen on the boat using salty brine glaze, rinse them for 30 seconds under cold running water.

After you’ve thawed king crab legs (in a refrigerator or cold-water tap) and rinsed them, pat them dry with the paper towel. As the king crab legs are long for the standard pots, cut them at the joints to make segments. It’ll make them fit into your baking sheet. You can also pre-crack the shells for the seasoning to reach the king crab meat. That’s optional, though.

Cooking frozen king crab legs without thawing? You can definitely do so. It’s just that you’ll have to cook it a few more minutes than fresh or thawed king crab legs. However, I suggest thawed king crab legs if you’re cooking king crab legs when it’s not king crab season. It’ll ensure even cooking.

Cooking King Crab Legs: Step-by-Step

I tried various methods for cooking king crab legs, and baking seemed the easiest to me. So, the following are the directions for baking king crab legs:

Take a small bowl for the seasoning mixture. Add melted butter to it. If you’re going with the optional ingredients, add them too and mix well.
Line up the baking sheet with aluminum foil and arrange the king crab legs on it. It’ll help with the cleanup later.
Use half of the seasoning mixture to brush over the king crab legs generously.
Cover the baking sheet tightly with the foil in order to trap the steam.
Bake for about 15 minutes.
When the king crab meat turns opaque white and the shells look brighter, take the sheet out of the oven.
Pour the remaining seasoning mixture over the crab legs and serve!
