Abstract: During microwave oven heating periods of sauces, gravies, custards, soups, eggs, chili and other foods warmed up, heated, or cooked, their required stirring is automatically undertaken by utilizing a microwave cooking assembly of a mixing bowl, a top assembly serving as a cover thereof, and a self contained stirrer power assembly thereof, supported by the top assembly. During the stirring of the food, a paddle of the stirrer power assembly, in moving through the food to stir or to mix the food, also substantially wipes and almost fully scrapes the food from the inner surfces of the mixing bowl, thereby eliminating any possibility of the creation of any hot spot portions in the food being heated by the microwave energy. Preferably, the top assembly serving as the cover is locked on the mixing bowl during the heating and stirring of the food, by utilizing interfitting and locking handles of both the bowl and top assembly.
