A controlled cooking system (CCS) that monitors, measures, and controls the internal temperature of foods placed in an oven having a Radio Frequency Identification (RFID) antenna(s), a transmitter / receiver / interrogator / reader / microprocessor (TRIRM) module and an RFID tag with built-in temperature sensor. The RFID tag is buried in the food being cooked and is energized and enabled by an RF signal of pre-determined frequency. The tag output is an RF “backscatter signal” having encoded temperature data indicative of the internal temperature of the food that the tag is buried in. The backscatter signal is received and decoded by the antenna(s) and the TRIRM module incorporating a programmed cooking / baking temperatures for various foods. If the decoded temperature is below a user-set temperature, the TRIRM module allows the oven to remain on. Conversely, if the decoded temperature is at or exceeds the user-set temperature, the TRIRM module shuts off the oven and produces a signal that activates an alarm indicating that the cooking has been terminated.
