A cooking apparatus, as in a domestic fryer, includes a stacked shell, cooking pot and basket combination. A heater element extends into the cooking pot and has a generally horizontal portion suspended above the pot bottom and supported by a support platform as in a volume reduction step-in region in the cooking pot and/or a removable basket support platform. The pot holds sufficient cooking fluid to provide for deep frying large food items as in a whole turkey (e.g., 3.63 Kg to 8.16 Kg). An embodiment includes a drain spigot with adjustable drain spigot cover assembly. The heating device includes a combination control unit and heating element that is releasably supported by the shell with a fail-safe electrical disconnect connection. The basket support platform and one or more temperature sensors are connected to the heating element and thus removable as well. The cooking pot has an edge recess for receipt of the heating element and for pot drainage.
