Electric ovens and microwaves meet different but complementary needs. A traditional oven is suitable for more complex cooking, such as roasts, vegetables, desserts, and gratin dishes; a microwave is useful for reheating, defrosting, and speeding up many everyday tasks. Before purchasing, it's helpful to consider capacity, power, programs, grill, ventilation, external dimensions, and ease of cleaning. In small spaces, a compact model can improve space management without sacrificing essential functions.
