It isn't every day you get a chance to enjoy the richness of lobster meat, and with the critters being so expensive, every cook should have a recipe to make use of the leftover bodies and shells.

This recipe is for lobster stock, but you can concentrate it and add a bit more salt to make a rich lobster broth, too. Use this as a soup base or for a fantastic lobster risotto or just have a cup of it on a cold day. It freezes well for up to six months.

Like many deep-sea creatures, lobsters are low in fat, but they are very high in cholesterol, with a whopping 212 milligrams. They're high in protein and vitamin B-12 also. It's usually the way we prepare lobster — with butter — that makes them a less-healthy option. But if you're looking for a special occasion meal, lobster is a delicious choice. 


  • 2 to 4 lobsters (leftover bodies and shells)
  • 4 tablespoons olive oil
  • 2 medium onions (chopped)
  • 4 stalks celery (chopped)
  • 3 carrots (chopped)
  • 2 cloves garlic (chopped)
  • 1 bulb fennel tops (chopped)
  • 1/2 pound mushrooms (chopped)
  • 4 tablespoons parsley (chopped)
  • 4 bay leaves
  • 4 to 5 plum tomatoes (chopped)
  • 1/2 cup white wine (or dry sherry)
  • 1 gallon water
  • Salt (to taste)

  12. Cook until it tastes full-flavored and then strain. Do this by turning off the heat, then grabbing all the big chunks with tongs and tossing them in the trash. Strain the rest through a fine-meshed sieve with a piece of cheesecloth set inside it.

  • This will keep for up to 10 days in the fridge or 6 months in the freezer.
  • There are a lot of ways to use your lobster stock (probably more than you think). One particularly decadent yet easy-to-make dish is lobster risotto. This traditional dish from Sardinia uses "leftover" lobster meat from the body as opposed to the claws and tail, which usually get eaten first.
