How to Make Instant Pot Crab Legs
Follow these step-by-step instructions to make Instant Pot crab legs in no time:
Set out the crab legs at room temperature for 15-20 minutes to allow them to partially thaw, just enough so you’re able to able to bend the legs a bit.
Add the water, salt, and Old Bay seasoning to the Instant Pot, then place either the strainer or a trivet in the bottom of your Instant Pot.
Place the frozen crabs, lemon, and garlic on top of the trivet, bending the legs a bit to allow the crabs to fit into the inner pot.

Secure the lid, then set the Instant Pot to High Pressure for 3 minutes. It usually takes 10-15 minutes to get up to pressure and begin cooking.
Once the cook time is done, carefully quick release the pressure by turning or pressing the steam release valve. Be careful while doing the quick pressure release so as not to burn or scald your hands!

Once all the pressure is released, open the lid. The crabs can sit in the inner pot for a few minutes to rest and keep them warm until you’re ready to eat them.
Carefully use tongs to remove the crab legs from the Instant Pot and set them on a platter. Spoon some of the liquid from the bottom of the pot and pour it over the crab legs. This helps to keep the crabs moist and flavorful!
Then use a nutcracker, crab cracker, or your hands and break apart the legs to remove the pieces of meat, discarding the shells as you go.
Serve with melted butter and sprinkle a little lemon juice on top. Eating crabs is messy! Make sure you have extra napkins on hand, and maybe a bib, too!

How to Store Leftover Instant Pot Crab Legs
Transfer leftover crab legs to an airtight container or bag. Store in the refrigerator for 3-4 days. You can also freeze leftover crab meat. Transfer to a freezer safe container or bag and store for 2-3 months.
What to Serve with Instant Pot Crab Legs
I always recommend serving crab legs with melted garlic butter for dipping the meat! If you’re following Whole30, serve with melted ghee instead of butter. It’s also great served over some spaghetti squash
or jasmine rice.
Add some tasty sides like bacon wrapped asparagus or tomato & avocado salad. This easy recipe goes great with some air fryer baby potatoes too.
Tips for Success
These few tips will help ensure success with this Instant Pot crab boil recipe:
- The amount of crabs that will fit depends on the size of your Instant Pot. An 8 qt. Instant Pot will fit approximately 2.5-3 pounds of snow crab legs (7-8 clusters), while a 6 qt. Instant Pot will fit approximately 2 pounds of crab legs (about 5-6 clusters).
- Snow crabs can be a little pricey. I recommend that you stock up on snow crab legs at Costco or when they’re on sale, then store in the freezer until you’re ready to cook them.
- Make sure you clean the lemons well and fully peel the garlic before adding them to the Instant Pot and pressure cooking your crab leg clusters.
FAQ
No, crabs can be cooked directly from frozen, but partially thaw the crab legs at room temperature for 15-20 minutes to make the legs easier to bend and fit inside the pot.
I recommend preparing 2-3 snow crab clusters per adult. This is the average serving size, but you can absolutely make more if you’d like!
