Cơm cháy is a Vietnamese name for scorched rice, that is, cooked rice that has been browned and crisped by direct heat. It is typically fried in oil until golden brown, then topped with chà bông (pork floss) or tôm khô (dried shrimp), mỡ hành (chopped scallions cooked by pouring boiling oil over them to release their aroma), and chili paste to produce a popular dish called cơm cháy chà bông or cơm cháy tôm khô (although both the pork and shrimp may be used, in which case the dish is called cơm cháy chà bông tôm khô or cơm cháy tôm khô chà bông).
Cơm cháy may be made from the crust of rice left over from cooking rice in an iron pot, or, more commonly since the advent of electric rice cookers in the late 20th century, from leftover rice that is fried in oil over high heat to acquire a crispy texture.
