PM Update: Scattered showers and thunderstorms through the early evening. Much cooler on Monday. You may have to dodge some raindrops through about 8 tonight. A cold front moves through tomorrow morning and ushers in much more seasonable weather.
Only cook live crabs, because they deteriorate very quickly after they have expired. You can simply throw the crabs in a pot of boiling water to cook them. Depending on the size of the crabs, it will take between 6 and 10 minutes for them to cook thoroughly. If the crab is alive when you start, the amount of cooking time has very little to do with safety  it s more a question of whether the meat is underdone, overdone, or cooked just right.
Best Answer: yes you can cook them in an oven. Sear them off him a skillet first to get them brown on either side and then cook them in a 350 degree oven for about 30 minutes and they should be done. Cook them to an internal temp of 145 degrees. Source(s): Im a chef and this is how we cook our crab cakes all the time. It'll depend on the size of them, but until the outside is golden brown and the inside is piping hot - usually 2-3 minutes each side unless they're really big, or 12-15 minutes in a hot oven. use 350 degrees as a base temp.
