The Best Lobster Bisque

Of all the dishes my Mom has ever made, her lobster bisque is the one that steals the show every time. Every person leaving the dinner party is either wanting more of it or trying to learn the recipe themselves. I will say this recipe takes some time and effort so be sure to only make it for the people who deserve it.

How to prepare lobsters for lobster bisque

One of the most important and time consuming parts of this recipe is separating and cleaning the lobster before it gets cooked in the wok. I will split this up into the different areas of the lobster.


The lobster tail requires the least amount of work. Using a pair of kitchen shears, cut from where the tail begins. This will be right under the upper portion of the lobster. The tail should easily dislocate and set this aside while we prepare the other sections.

The legs are located on the upper portion of the lobster and they are dangling down. The legs are relatively weak and can be cut off easily with kitchen shears.


The claws are connected to the upper portion of the lobster which is also very easy to cut off with a pair of kitchen shears. I would recommend making a crack in the claw because it will make it easier to extract the meat later.

The last body part remaining is the head and it also takes the most steps to prepare. First, you will want to cut it in half in between its eyes. This way you expose the center of the head and can begin to remove the “brain”. This is the green looking substance pictured below.

After the brain has been removed, there are a set of gills on the outside of each half of the head which I would recommend removing as well. The way to do this is by cutting them off with a pair of scissors.

The last step is to cut off the antenna because no one wants to deal with that thing dangling around. Once all of the lobsters are prepared, then we can begin cooking.

Corn starch slurry in lobster bisque

A corn starch slurry is used in this recipe as a thickening agent along with heavy cream. It is basically a mixture of corn starch with water. If you still feel as though the soup is not thick enough, continue to add more of the corn starch slurry to help thicken it.

Strain out all lobster bisque solids

After your soup has been simmering for 2.5 hours covered, make sure to run it through a fine sieve. Otherwise you will be left with solids in your soup and that is not the texture we want. We want a smooth and slightly creamy consistency with a ton of flavour.
