The most popular size overall, 1.5-pound lobster “halves” are still sweet, tender, and reasonably easy to cook while still yielding a reasonable amount of protein for a full meal. We still recommend serving plenty of sides for group events where there will inevitably some guests with bigger appetites than the rest, especially if you’re also serving alcohol at the event. If you know a few of your guests tend to be heartier eaters, you might order and set aside a few 2-pound lobsters for these guests.
More Tips for 1.5 lb Lobster
Along with quarters, the 1.5-pound lobster is the most affordable choice for live lobster. You can still make an 8-quart cooking pot work, but it’s not ideal. We recommend a full 16- or 20-quart cooking pot for this size lobster, and you should have little trouble fitting 3-4 lobsters in these pots, respectively. Given that the rule for cooking lobster is 7 minutes for the first pound and about 3 minutes for each additional pound, our advice is to cook the lobster between 9-10 minutes.
A 1.5-pound lobster should yield about 5-5.5 oz of cooked lobster with the following nutritional information:
140-150 grams, 5-5.5 oz
27-29 grams of protein
90-100 mg of cholesterol
1.5-1.75 grams of fat
Some lobster companies also offer a 1.75-pound lobster category. Others go straight from 1.5 to 2-pound lobsters, which means you might also get a little extra if you order a 1.5-pound lobster and the company happens to grab a slightly bigger one when preparing your order.
