Common Mistakes When Cooking Precooked Crab Legs from Costco

Cooking pre-cooked crab legs can be tricky, and certain common mistakes can ruin the entire experience. But don’t worry – with a few simple tips, you can avoid these mistakes and enjoy perfectly cooked crab legs every time.

Mistake #1: Overcooking the Crab Legs

The most common mistake people make when cooking pre-cooked crab legs is overcooking them. Since they’re already cooked, all you need to do is heat them up. Overcooking can cause the meat to become tough and chewy, ruining the delicate texture. To avoid this mistake, steam or boil the crab legs for just a few minutes until they’re heated through. Alternatively, bake them in the oven for 10-12 minutes at 350°F.

Mistake #2: Improper Thawing

Thawing crab legs properly is crucial to maintain their quality and freshness. Thaw them overnight in the refrigerator or by placing them in a sealed plastic bag and submerging them in cold water for 30 minutes to an hour. Avoid thawing at room temperature or under hot water as this can cause bacteria growth and spoilage.

Mistake #3: Using Too Much Seasoning or Sauce

The delicate flavor of crab meat can easily be overpowered by too much seasoning or sauce. Keep it simple with just a sprinkle of salt and pepper or a light butter sauce. Moreover, avoid using metal utensils such as tongs or forks that can damage the delicate meat.

Mistake #4: Not Serving Immediately

Timing is everything when it comes to serving cooked crab legs. Serve them hot with melted butter on the side for dipping. Leaving them out for too long can cause them to dry out and lose their flavor.
