Khao piak khao is a thick Laotian rice soup that is traditionally served for breakfast. It is considered a comfort food staple that is often made in vast quantities and served to a large group of people. The base of the soup is made with chicken stock and various chicken parts (either thighs, bone-in breasts, or wings), but other versions use pork instead.

The broth is seasoned with galangal, lemongrass, and kaffir lime leaves, but most eateries also offer condiments and flavorings such as fish sauce, chili sauce, and sugar. Garnished with chopped scallions, fried garlic slices, and coriander leaves, the soup is served hot and makes for an affordable and filling breakfast.
