Queso Oaxaca is a white, semihard cheese from Mexico, similar to unaged Monterey Jack, but with a mozzarella-like string cheese texture. It is named after the state of Oaxaca in southern Mexico, where it was first made. It is available in several different shapes. It is also known as quesillo Oaxaca or thread cheese when shaped like a ball. Shaped in bricks for slicing, it is called asadero (meaning "roaster" or "broiler") or queso quesadilla.
