An on-demand automated aseptic fryer may be used to prepare multiple types of fried foods without requiring vats of hot oil. The fried foods that may be prepared include, for example, donuts or potatoes, or any other fried foods that can be prepared from a dry mixture that produces a dough when mixed with water. Alternatively, the dry mixture may include a dried, powdered or reconstituted fruits or vegetables that are subsequently mixed with water. The entire process is automated once the process is initiated by a user and thus does not require an attendant during the frying process, which in some implementations can be completed in less than about 1.5 minutes once initiated.
