Regarding cooking appliances, two popular options often leave consumers in a dilemma: the OTG microwave and the convection microwave. Both appliances offer unique features and capabilities, making them highly sought after in modern kitchens. A microwave cum OTG is a versatile kitchen companion that combines the functionality of an oven, toaster, and grill with a microwave in a single appliance. On the other hand, a convection microwave combines the convenience of a microwave with the baking and roasting capacity of a convection oven. In this article, we will delve deeper into the functionalities and advantages of both appliances to help you make an informed decision. 

Understanding OTG Microwave:

An OTG microwave, which stands for Oven, Toaster, and Grill microwave, is a versatile kitchen appliance that combines the functionalities of a microwave, oven, toaster, and grill in a single unit. This appliance offers a range of cooking options and is ideal for those who want a multi-purpose cooking device. The microwave function of an OTG microwave allows for quick and efficient heating and cooking using microwaves. The OTG function enables baking, roasting, and cooking dishes that require traditional oven cooking methods. With temperature control and adjustable racks, you can prepare various recipes.

Understanding Convection Microwave:

A convection microwave combines the functions of a microwave and a convection oven. It offers the convenience and speed of a microwave and the ability to perform baking, roasting, and other cooking tasks associated with a convection oven. The microwave function in a convection microwave uses microwaves to heat and cook food, providing quick and efficient heating, defrosting, and cooking of food. In addition to the microwave functionality, a convection microwave also features a heating element and a fan responsible for generating radiant heat. In contrast, the fan circulates the hot air within the appliance. This creates a convection effect that allows even cooking and browning, similar to a traditional convection oven.

OTG Microwave vs Convection Microwave - The Difference:

Which is More Versatile - OTG Microwave or Convection Microwave:

When comparing the versatility of an OTG microwave and a convection microwave, the latter generally offers more versatility. A convection microwave combines the functions of a microwave and a convection oven, allowing for a broader range of cooking methods. It can microwave, bake, grill, and roast. In contrast, a microwave cum OTG combines the functions of an oven, toaster, grill, and microwave, which limits its versatility compared to a convection microwave. A convection microwave utilizes both microwaves and convection heating. This combination enables quick heating with microwaves. The evenness of cooking is also improved in a convection microwave due to the hot air circulation, resulting in more consistent cooking and browning. However, if you are just starting out, we recommend you should choose the OTG microwave as they are budget-friendly and easier to use.
