Lacassá Soup[1] (Portuguese: Sopa de lacassá,[2] traditional Chinese: 鮮蝦濃湯; simplified Chinese: 鲜虾浓汤[3]) is a Macanese soup.

[4] The word Lacassá is noted to be a Macanese term for vermicelli, with roots in Indian languages.

[5] As it contains no meat, Lacassá Soup is traditionally consumed on Christmas Eve, historically a day of abstinence for Catholic faithfuls.

[6] Lacassá Soup is also featured in a proper Cha Gordo, a social event that has been likened to high tea, and features multiple dishes.

[7] Lacassá Soup contains vermicelli (hence its name, as explained above), shrimp, and balichão.
