Can You Microwave Crab Legs

You can microwave king crab legs for a quick, easy dinner or appetizer. However, you must exercise caution, or the meat will dry and toughen.

So, why exercise caution?

Well, first, they overcook easily. King crab legs are a delicate dish and thus should be handled with care. Their meat is softer than other crustaceans such as lobster and shrimp and should not be cooked any longer than necessary.

Second, they come pre-cooked. Due to their scarcity, king crab legs often come pre-cooked and flash-frozen to preserve freshness. As a result, they only require reheating before serving. Subjecting them to heat for too long or at too high a temperature will dry out the flesh and make it tough.

Third, microwaves tend to cook unevenly. This means cold and hot spots in your food, resulting in undercooked or overdone pieces. Also, the high microwave temperatures can break down proteins in crab legs, causing them to become mushy.

Finally, because king crab legs are categorized as meat, improper cooking may increase the risk of foodborne illness. As a result, you must thoroughly cook them to eliminate any potentially harmful bacteria. The disadvantage is that they could lose texture and flavor in the process.

So, how do you strike the perfect balance between overcooking the meat and preserving its natural flavors?

Tips for Microwaving King Crab Legs

How to Microwave Frozen King Crab LegsEvery cooking process or recipe has a set of rules that you must follow, and microwaving frozen king crab legs is no exception. So, here are some tips for reheating them in the microwave:


  • Purchase only vacuum-sealed king crab legs from reputable seafood suppliers. Check the package for tears or ice crystals, as these can indicate freezer burn or spoilt meat.
  • Do not microwave your crab legs in their original packaging because they’ll melt, leaching toxins into the food. Instead, use a microwave-safe plate large enough to hold all the pieces without overlapping.
  • If the legs don’t fit on the plate, split them so that each one can heat evenly. A nutcracker makes quick work of this task, but if you don’t have any on hand, a sharp knife will suffice.
  • King crab eggs come frozen; therefore, the need to thaw them first before microwaving. The best way to do so is by leaving them overnight in the fridge or microwave on defrost. If you choose the latter, heat in short bursts to avoid drying them out.
  • Wrap your crab legs in a damp paper towel or napkin to keep them moist while they cook. If desired, cover with microwavable plastic wrap to trap moisture and reduce splatter.
  • Throw some tarragon sprigs over the legs before microwaving. The herb’s flavor will complement the dish well. Serve with lemon wedges, melted butter, and salt and pepper to taste.

In the absence of paper towels, add a tablespoon of water to the bottom of the dish. Use the ratio of 1 tablespoon of water per 8 ounces of seafood.

Remember not to overfill your dish with too many legs at once, as it will take longer to cook—instead, microwave in batches of 8 ounces (1 pound) of crab legs at a time.

Step 5: Set your microwave to high power and cook for 2 minutes. See if they’re hot enough by poking one of the legs with a fork. If not, put them back in the microwave and heat in 30-second intervals until a temperature of 165 degrees Fahrenheit is reached.
