3. Preparing Crab Legs for Boiling

Before you boil crab legs, it’s important to prepare them properly to ensure they cook evenly and taste their best. Here's what you need to do:

Thaw the Crab Legs:

If your crab legs are frozen, place them in the refrigerator to thaw overnight. For a quicker method, run them under cold water for about 20 minutes until fully thawed.
Thawed crab legs cook more evenly and absorb seasonings better.

Rinse the Crab Legs:

Rinse the crab legs under cold water to remove any dirt or sand. This is especially important if you're working with fresh or wild-caught crab.

Pre-Cut the Shell (Optional):

For easier eating, use kitchen shears to cut a slit along the length of the shell on each leg. This makes it easier to access the crab meat after boiling.

4. How to Boil Crab Legs: A Step-by-Step Guide

Follow these steps to boil crab legs perfectly every time.

Step 1: Prepare the Pot

Fill a large pot with water, leaving enough room for the crab legs so the water doesn’t overflow.
Add a pinch of salt and any desired seasonings to the water. Many people like to add Old Bay seasoning, garlic cloves, or lemon wedges to infuse extra flavor.

Step 2: Boil the Water

Bring the water to a rolling boil over high heat.

Step 3: Add the Crab Legs

Once the water is boiling, carefully add the crab legs to the pot. You can do this in batches if your pot isn’t large enough to hold all the crab legs at once.

Step 4: Boil the Crab Legs

Boil the crab legs for 5-8 minutes, depending on their size. Snow Crab legs typically take 5-6 minutes, while King Crab and Dungeness Crab legs may take up to 8 minutes.
You’ll know the crab legs are done when they turn bright orange or red and the meat is opaque.

Step 5: Drain and Serve

Remove the crab legs from the boiling water using tongs and let them drain in a colander for a minute.
Serve hot with melted butter, garlic butter, lemon wedges, or your favorite dipping sauce.
