Much of the cuisine has its origins in Malay, Indonesian, and Indian food. Favourite dishes from the south include Indian-style Muslim curry (massaman), rice noodles in fish curry sauce (khanom chin), and khao mok kai (chicken biryani). Unsurprisingly for a coastal region, seafood features prominently on the menu. Traditional southern Thai food includes milder coconut-milk based curries popularly associated with Thailand: the dry, Malaysian-influenced Panang curry and Indian-influenced massaman (Muslim) curry with potatoes and nuts.

The wing shell (หอยชักตีน) is Krabi's best-known dish. In addition, stir-fried spotted Babylon (หอยหวาน) with chilies and basil is also noteworthy.
