Lobster soup


Swedish style lobster soup

Hummersoppa (lobster soup) is regarded as the king of soups in Sweden. It is also a superb way of using up left over lobster shells!

For a special occasion, garnish it with some fresh lobster to make a sumptuous starter or a luxurious light lunch. In Sweden, this is one of the most popular ways of enjoying lobster in the autumn and on festive occasions such as on New Year's Eve.

Our recipe was given to us by Johan Sköld, the Head Chef at Hotell Koster on the island of Sydkoster off the west coast of Sweden. It is one of the sunniest spots in Sweden and produces some of the country's finest lobsters. (To read more about lobster click here.)


Recipe summary for lobster soup


• This makes a wonderfully rich soup, but if you are concerned about the amount of cream you can either serve very small portions or replace all the cream with a good quality fish stock and then add four tablespoons of cream in step 10. (For health reasons this is how I normally make it.)
• Serve the soup with dill toast as shown above or cut into heart shapes as shown below.
• You can freeze lobster shells until you want to make this soup, but do this as soon as possible after cooking the lobsters and use them within two weeks. To use them, defrost them for 30 minutes and then, whilst they are still in the freezer bag, break them up into really small pieces using a mallet.
• Try cooking lobster yourself. It really is quite easy! For our recipe click here.

Crushed lobster shells make a good base for lobster soup

3. When the shells are cold enough to handle, break them up as much as possible with a mallet. (The smaller the pieces the better the flavour.)

4. Heat a tablespoon of butter in a large pan. When melted, add the crushed lobster shells. Sauté for a few minutes until it begins to smell quite lobsterish, then remove from the heat, add 2 tablespoons of brandy and flambé the shells.

Luxury version

Lobster meat in a soup bowl

Roughly chop the tail meat from two lobsters and add four claws to an oven proof dish. Cover with foil and place in a warm oven for a few minutes to warm through. (The meat only needs to be gently warmed through and not cooked because otherwise it will become rubbery.) Divide the meat between four dishes and carefully pour the soup around the meat. Garnish with dill if desired.

Dill toast

Dill toast cut into heart shapes

Dill toast makes an attractive garnish and for a special occasion it looks really nice when cut into heart-shapes. It is also easy to make!

8   slices of white sourdough bread
2   garlic cloves, peeled
40 g (⅓ stick) butter, softened
4 tbsp   finely chopped fresh dill


1. Preheat the over to 220°C (425°F, gas 7, fan 190°C).

2. Cut the bread into heart shapes.

3. Halve the garlic cloves and then use the cut faces to wipe one side of each slice of bread.

4. Mix the butter and chopped dill together. Spread the mixture over each piece of bread.

5. Bake for 3-5 minutes until golden brown at the edges.
