Steamed Lobster

Lobsters are a snap to cook. There are two schools of thought on how to best cook live Maine Lobster. One is boiling and one is steaming. (We’ll get to grilling in another section!). Steaming cooks whole lobsters more slowly than boiling, so it reduces the chance of overcooking. It also makes less of a mess, but heck, that’s what bibs are for.

For cooking a bunch of lobsters, boiling gives you even, fast cooking. Steaming can be a bit more tricky than boiling for most folks. We know a friend who loaded a tall, narrow pot with about 10 lobsters and wondered why the steam didn’t get all the way up the pot to cook the critters on the top of the pile. Remember to not overload your cook pot and that the size of the pot, as well as the ratio of water to lobsters is critical in steaming.

Steaming

The first word of caution is DO NOT OVERLOAD THE POT! We’ve seen too many people try to steam a large group of lobsters all at once in a big pot. They stacked them in deep and then wondered why the top ones were still alive! The steam will not rise up through a tall stack stuffed in a pot so don’t cook too many at once in a pot.

The ratio of lobsters to the pot is important; a 4-5 gallon pot is ideal for steaming 6-8 pounds (3-5 whole) of lobster. Put 2 inches of salted water in the bottom of a large kettle. Set a steaming rack inside the pot and bring to a rolling boil over high heat. Put in the live lobsters, one at a time, cover the pot, and start timing. Re-arrange the lobsters halfway through cooking. Steam a lobster for 13 minutes per pound, for the first pound. Add 3 minutes per pound for each additional pound thereafter. For example, a 2-pound lobster should steam for 16 minutes and a 1 ½-pound lobster should steam for 14½ minutes.

Cooking times are approximate based on stove and cooking conditions and the lobster-to-pot ratio mentioned above – the taller you’ve stacked the lobster in the pot, the longer they will take to cook. Check regularly. The lobsters are ready when they are bright red and the antenna pull out easily.

Preparation:
  • 1 pound -- 12 minutes
  • 1-1/4 pounds -- 13 minutes
  • 1-1/2 pounds -- 14 minutes
  • 1-3/4 pounds -- 16 minutes
  • 2 pounds -- 17 minutes

In the winter, lobsters have a harder shell and therefore require more time to cook. In the summer, the lobsters have a softer shell and require less time. Note: If the roe inside a female body is blackish instead of the customary red, it is undercooked. Put the lobster back into the pot until the roe is red.
