An engine control method of a hybrid electric vehicle is provided. The method includes detecting a state of charge (SOC) of a main battery of the hybrid electric vehicle and detecting whether a brake requires operation when the main battery is in a fully-charged state or a charging-limiting state. An engine fuel cut of the hybrid electric vehicle is executed when a request for the engine brake is generated and an engine is operated to maximize an engine load of the hybrid electric vehicle.
