You don’t need to spend a ton of time and lots of big bulky equipment in order to cook blue crabs. Grab your Instant Pot and get ready for the quickest and easiest way to cook blue crabs.
The best way to get blue crabs is to catch them
Guarantee the freshest crabs by catching them yourself! Read our Crabbing on the Gulf Coast post to find out how. But if that is not an option, check your local seafood section at the grocery or order online.
Use live blue crabs
According to Science Focus, blue crabs have a harmful bacteria that multiplies and releases toxins very quickly as soon as the crab dies. Cooking does not always eliminate the toxin so it is recommended to boil or steam live crabs.
The most important thing about cooking blue crab to note is that you cannot cook crabs that are dead; as soon as they die they start to rot and become toxic.Cameron’s Seafood
TIP: Placing the crabs on ice for a short time before cooking slows them down and makes them easier to handle.
Prepping the pot for the crabs
For this recipe, we used our 6 qt Instant Pot. Place the trivet on the bottom of the pot and pour in one can of your preferred beer. Then add about a half a cup of vinegar (this helps the meat come out of the shell easier). Cut up an onion and a lemon into large chunks and toss in the pot.
Add the crabs and lots of Old Bay Seasoning
Preferably with tongs, grab the crabs and place them in the pot. As you place each one in the pot, liberally sprinkle Old Bay Seasoning on the crab. For this size Instant Pot, we can easily fit 8 crabs.
Place the cover on your InstantPot and set it on manual pressure for 5 minutes. When it is finished, do a quick release of the pressure.
Properly cooked crabs will have a bright red shell
Remove the cover of your Instant Pot and the crabs are ready for you to enjoy! A properly cooked crab will have its shell turn from the green/blue colors to a bright orange/red hue.
