Kalakeitto or fish soup has been a staple of traditional Finnish cuisine for a long time. Although there are numerous ways to prepare this classic Finnish specialty, it typically consists of cleaned and filleted fish chunks and diced vegetables that are simmered in a rich, buttery fish broth.

Carrots, potatoes, onions, and leeks are among the most common vegetables used for the soup’s preparation, while the choice of fish includes salmon, rainbow trout, vendace, pike, perch, zander, or burbot. Traditionally, the soup is enhanced with the addition of butter and cooking cream (ruokakermaa), and it is usually flavored with dill, allspice, bay leaves, salt, and pepper. 

Lohikeitto is a creamy Finish salmon soup, similar to laxsoppa in Sweden. Apart from chunks of salmon fillet, it traditionally incorporates diced potatoes and carrots cooked in a flavorful, buttery broth infused with fish stock and cream.

This comforting winter dish is generously seasoned with dill and served alongside buttered rye bread or lemon wedges.

Tom Yum is one of the best known Thai dishes, a spicy, sour, and aromatic soup that is traditionally served with rice. It consists of shallots, lemongrass, fish sauce, minced fresh ginger or galangal, shrimps, mushrooms, kaffir lime leaves, lime juice, and minced Thai chili peppers.

Usually served as an appetizer, tom yum is traditionally garnished with coriander leaves on top. Due to its popularity, different versions of the soup started to appear over the years, such as tom yum gai, with added chicken, and tom yum talay, with mixed seafood. 

Chupe de camarones is a popular Peruvian shrimp (or prawn) chowder with a long and unusual history. The chowder is typically made with fish stock, fresh shrimps, onions, garlic, and yellow potatoes, while rice, beans, carrots, and peas are used often, but not always.

The dish is traditionally served in deep bowls and garnished with parsley. In recent years, food historians have revealed that chupe de camarones actually evolved from a thick Arequipeño stew made with potatoes, llama meat, and herbs. The dish was called chuwa misa (lit. deep bowl) and was prepared before the 16th century. 

Even though it has been traditionally prepared all along the coast, Cullen skink is a dish originating from the fishing village of Cullen in Northeastern Scotland. This thick and creamy fish soup is typically based on smoked haddock cooked with milk, leeks, onions, and potatoes which provide the filling bulk.

Some recipes specify the use of Arbroath smokies, although just about any smoked white fish will do. Cullen skink will go hand in hand with a glass of dry white wine, but to indulge in a true Scottish feast, try pairing it with Scotch whisky.

Shrimp bisque is a traditional Cajun dish originating from Louisiana. The soup is usually made with a combination of large shrimp, seafood broth, shrimp broth, butter, bell peppers, shallots, garlic, flour, cream, brandy, hot sauce, and seasonings.

The shrimps are simmered in the broth until the liquid is reduced, while a combination of butter, bell peppers, shallots, and garlic is sautéed and sprinkled with flour and mixed with brandy and cream until the combination becomes thick. The cooked shrimps are added to the pot and simmered until hot, and the dish is then served, often garnished with sliced green onions or parsley. 

She-crab soup, somewhat of a cross between a bisque and a chowder, is a soup made with heavy cream or milk, crabmeat, sherry, fish or crab stock, and roe—a key ingredient in the dish that improves the flavor and is responsible for the color.

The soup is thickened with a roux or puréed boiled rice, and it is usually seasoned with either mace, onions, or shallots. A regional specialty of Tidewater, Virginia, the South Carolina Lowcountry, and Georgia coast, it was first introduced to these parts by the Scottish settlers in the 1700s in the form of partan-bree, a famous seafood bisque, but it was not until the 1900s that the soup gained its present-day form.

Traditionally associated with the regions of Kelantan and Terengganu, this flavorful Malaysian soup consists of rolled rice noodles served in a creamy fish broth. The noodles are prepared with a thin rice flour batter that is poured on a flat surface, steamed, and then rolled and sliced into bite-sized pieces.

The broth served alongside the noodles is made with coconut milk and creamy fish paste, and is usually seasoned with ginger, shallots, and garlic. The whole dish is complemented by various vegetables such as sliced cucumbers or green beans and is usually accompanied by spicy sambal. 

Encebollado is the national dish of Ecuador, a fish soup that is characterized by a large amount of onions. Very useful in curing hangovers, the dish is made with fresh tuna meat, cassava root, tomatoes, onions, coriander, and various spices. Tomatoes, onions, chili, coriander, and cumin form a pungent mix and a base for the soup, called sofrito, while pickled onions go either on top of encebollado or into it, giving it its name that is literally translated to onioned.

The soup originates from Ecuador's coast during the time when the fishers were out at sea and made the soup out of necessity. As they had some spices, and fresh fish was readily available, encebollado was created and became widely consumed throughout the country.
