In making this shrimp bisque, we use the power of heat and boiling water to extract flavour and minerals from crustaceans’ shells and vegetables. It provides a large richness, because they contain hearty tasting amino acids. Raw shrimp contains roughly 50% meat and 50% head, tails and shells by weight. But we use the latter part for making the broth. Some cooked shrimp meat contributes, but the uncooked shells provide this dish with the deep taste.
Origin of the shrimp bisque
This soup originates from France. Bisque may refer to Biscay. The Bay of Biscaye is an often rough part of the Atlantic ocean bordering France’s south-west coast and Spain’s north-east coast. It is also a region in north-east Spain. Shrimp, crab and lobster soups are the most well known of the bisque family. As the taste is unique among all fish and shell fish soups.
The art of making shrimp bisque
Two things are important: heat to brown shrimp shells and vegetables and then simmering water to extract the flavorful vegetable juices and minerals. For making this soup, all the taste is actually extracted by the water and a little bit by the oil. All extracted solids such as the shrimp shells and heads but also the vegetables are discarded after a brief simmer.

Ingredient to make the final bisque
Instruction to make the broth
Wash the vegetables and herbs to ensure there is no sand or rubbish
Cut the onion (skin on), the leek, the cellery sticks, the fennel, the carrot (skin on), the tomato (skin on) in course pieces
Measure the anice liquor and ready the tomato paste
Heat up the olive oil in a pan on high heat
Add the shrimp shells and mix. The shells will become orange. Keep the high fire but ensure there is no black burning. But brown spots on the pan and shrimp shells are fine
Under stirring, add the onion parts
After one minute add the leek. Followed by the cellery parts, the carrot, and the fennel and the parsley stems, each added after 30-60 seconds
Add the tomato and the tomato paste and bring the fire to low-medium. Wait 2 minutes
Then add the anise liquor and the brandy, stir and scrap the bottom and add so much chicken broth that the mixture of shells and vegetables is almost submersed. Do not add too much broth!!! Err on the low side
Cook the raw shrimps in little water, until orange. Add the cooking water to the broth and reserve the shrimps
Add the salt, pepper, thyme and rosemary and continue to simmer for 25 min
After 25 minutes, strain the broth and press out the shell/vegetable mixture with a spatula. Take time to press, as there is a lot of great taste in the juices that are pressed out
Let the broth cool down a bit, taste and where needed correct the salt level and use for the next step
Instruction to make the beachamel thickened broth
In a separate pan, melt the butter and then add the flour. Mix with a whisk
Let heat through at low-medium fire for 1 minute
Add the milk on low heat and use the whisk to mix in the milk. A course non-fluid crumbly 'dough' is formed
To this add in portions the broth at medium heat. Every time let thicken and then add more broth while stirring often.
Cut the cooked shrimp in pieces and leave some whole. Mix the cut shrimp with the soup and let the lightly thickened bisque simmer (low heat!) for 15 minutes.
Instruction to finalize the bisque
Method: pan frying, simmering
Food allergy & intolerance information: shell fish, gluten, cow's milk
- Adding some cream is preferred, but not essential
- The bisque is lightly bound by making a béchamel sauce, which also makes the soup taste more gentle and soft.
- If you use the head, ensure they have been cleaned inside and taken off when the shrimp was freshly harvested. Otherwise only use (more of) the shells and tails.
