Is It Safe to Microwave Crab Legs?

The short answer is yes It is safe to reheat crab legs in the microwave

Microwaving crab reheats the legs quickly while keeping bacteria at bay. As long as you follow proper food safety rules, microwaved crab legs are good to go.

Make sure the crab legs are fresh before reheating. Check for any signs of spoilage like bad odors or sliminess. Discard any questionable crab legs to avoid foodborne illness.

Store cooked crab legs in the fridge at 40°F or below. Don’t leave them out for more than 2 hours. Refrigerate any leftovers within this time frame.

When ready to reheat, make sure the crab legs are thawed completely if frozen. Always reheat crab legs to an internal temperature of 165°F to kill any bacteria present.

Follow the microwave reheating instructions properly, and your crab legs will be safe to eat again.

How to Reheat Crab Legs in the Microwave

Reheating crab legs in the microwave is easy but there are some steps to follow:

1. Prepare the Crab Legs

  • Thaw frozen crab legs completely before reheating. Defrost in the fridge overnight. Microwaving frozen crab can create uneven hot and cold spots.

  • Give fresh or cooked crab legs a rinse under cool water. This removes any debris. Pat dry with paper towels.

  • Remove crab legs from the shell if desired. This allows for more even reheating.

2. Arrange in Microwave-Safe Dish

  • Place crab legs in a single layer in a microwave-safe dish. This allows for direct exposure to microwaves.

  • Don’t overcrowd. Legs should have a bit of space between them.

3. Add Moisture

  • Add a few tablespoons of water or lemon juice to the dish. This creates steam to keep crab meat moist.

  • For sauced crab legs, skip additional moisture. The sauce will provide enough.

4. Cover and Microwave

  • Cover the dish loosely with a lid or microwave-safe plastic wrap. This traps in steam.

  • Microwave for 2-3 minutes per 8 ounces of crab legs. Adjust time as needed.

  • Rearrange and rotate crab legs at the halfway point. This prevents cold spots.

5. Check for Doneness

  • Check if legs are heated through. Aim for an internal temperature of 165°F.

  • If needed, microwave in 30 second intervals until hot. Be careful not to overcook.

  • Let crab legs rest 2-3 minutes before serving. This finishes off cooking.

And that’s it! Follow these straightforward microwave steps for reheated crab leg perfection.

Microwave Power Level for Crab Legs

Choosing the right microwave power level is key. Here are some microwave power guidelines:

  • Use a lower power from 30-50% when reheating crab legs. This allows for gentle, even heating.

  • Higher power can cause overcooking, creating rubbery crab meat. Start lower and increase power if needed.

  • For a 1100-watt microwave, try power level 5 or 6. For a 700-watt microwave, go with power level 3 or 4.

  • Adjust the power level based on the amount of crab legs and your microwave wattage.

Following these microwave power recommendations prevents crab legs from getting tough and chewy.

How Long to Microwave Crab Legs

Microwave times for reheating crab legs depends on a few factors:

  • Amount of crab legs – The more crab legs, the longer the microwave time.

  • Thickness – Thicker legs need more time than smaller, thinner ones.

  • Wattage – Higher watt power microwaves heat faster than lower watts.

  • State of legs – Frozen legs take longer than thawed or fresh.

With those in mind, here are general microwave time guidelines:

  • 1-2 minutes per 8 ounces for thawed crab legs

  • 3-5 minutes per 8 ounces for frozen crab legs

  • Add 30 seconds to 1 minute for thicker crab legs pieces

  • Add 1-2 minutes if microwaving a full 1-2 pound crab leg cluster

Check for doneness and add heating time accordingly. Err on the side of caution to prevent overcooking.

Should You Microwave Crab Legs?

There are pros and cons to microwaving crab legs. Here are some things to consider:


  • It’s quick and convenient

  • Microwaves reheat evenly when done properly

  • Moisture can be added to prevent drying out

  • Safe to eat when fully reheated to 165°F


  • Can create rubbery, chewy texture if overcooked

  • Doesn’t impart flavor like oven roasting or grilling

  • Not the best for heavily sauced crab legs

For many folks, the speed and ease of the microwave outweighs the cons. But for the best texture and flavor, oven roasting or grilling may be preferable.

Tips for the Best Results

Follow these top tips for flawlessly reheated crab legs using the microwave:

  • Defrost completely first – Microwaving frozen crab leads to uneven cooking.

  • Use lower power – This prevents overcooking and rubbery meat.

  • Add moisture – A splash of water or lemon juice steams the crab legs.

  • Heat in intervals – Rearrange and rotate legs to prevent cold spots.

  • Check for doneness – Use a food thermometer to test internal temperature.

  • Let rest before eating – This finishes cooking and allows juices to set.

Signs of Overcooked Crab Legs

It’s easy to overdo it in the microwave. Here’s how to tell if your crab is overcooked:

  • Chewy, rubbery texture

  • Dry, flaky meat

  • Lack of moisture and juiciness

  • Loss of delicate crab flavor

  • Papery, thin appearance

  • Split, broken shell

Catch overcooking early by microwaving in short intervals. And err on the side of less time rather than more.

Alternative Reheating Methods

Microwaving offers speed and convenience. But it’s not your only reheating option. Consider these alternatives:


  • Preheat oven to 325°F.

  • Place crab legs on a baking sheet and roast 7-10 minutes until hot.


  • In a pan or pot, bring 1 inch water to a boil.

  • Place legs in steamer basket over water and steam 4-5 minutes.


  • Heat butter or oil in a pan over medium-high heat.

  • Sauté crab legs 2-3 minutes per side until heated through.


  • Oil crab legs lightly and grill over direct medium heat.

  • Grill 2-3 minutes per side until legs are hot.

While a bit more time consuming, these oven roasting, steaming, sautéing, and grilling methods may provide better texture and flavor.

Storing Leftover Crab Legs

Have leftover reheated crab legs? Here’s how to store them:

  • Let crab legs cool completely before storing.

  • Place in an airtight container or resealable plastic bag.

  • Refrigerate for up to 2 days.

  • Label container with date for easy tracking.

  • Discard if older than 2 days. Don’t risk eating spoiled crab.

  • Never re-freeze previously frozen crab legs. This creates unsafe texture changes.

Follow these storage tips for safe leftover crab legs after reheating.

Can You Reheat Crab Legs Again?

It’s best to avoid reheating crab legs more than once. Here’s why:

  • Multiple reheatings lead to incremental moisture loss. This turns crab meat dry and rubbery.

  • Flavor and texture degrade with each reheating session.

  • Bacteria have more opportunities to grow and multiply.

  • Previously frozen then thawed legs cannot be safely refrozen.

For food safety and quality, just reheat leftover crab legs one time. Then discard any remaining portions instead of trying to reheat again.
