A microwave oven is a kitchen appliance that uses microwave technology to cook food faster than traditional ovens. There are three main types of microwave ovens: solo, grill, and convection. In this answer, we will focus on convection and grill microwaves.

Convection Microwave A convection microwave combines the standard features of a conventional microwave oven with an additional convection heating element that can help roast, bake, and crisp food. It uses a fan and a heating element to cook food, similar to a regular oven. The fan circulates hot air around the cavity, letting you bake and roast food with home-cooked results. You can expect faster cook times on certain items as the convection element and microwave cook simultaneously, and convection microwaves come with racks that let you microwave multiple dishes at once. Convection microwaves can cook food in many ways, such as baking, roasting, and grilling. They are good for cooking large meals and are more versatile than grill microwaves.

Grill Microwave A grill microwave is a type of microwave that has a heating element on the top of the microwave. It is used to grill food and give it a crispy finish. This model can grill food in addition to performing all of the usual functions of a single microwave oven. Grilling trays are sometimes included with the products of some manufacturers. Grill microwaves can only grill food from the top and are better for cooking small meals or snacks. They are perfect for reheating pre-cooked pastries and pizzas, as they can reach a high temperature in a short time.

In summary, the main difference between convection and grill microwaves is the way they cook food. Convection microwaves use a fan and a heating element to cook food, similar to a regular oven, and are more versatile than grill microwaves. Grill microwaves have a heating element on the top of the microwave and are better for cooking small meals or snacks.
