What is an OTG oven

An OTG oven, short for ‘Oven, Toaster, and Griller’, is a versatile kitchen appliance that combines the functions of a traditional oven, a toaster, and a grill. It is designed for baking, toasting, grilling, and reheating food. OTG ovens are compact and user-friendly, making them ideal for small kitchens or anyone looking for a multi-purpose cooking solution.

What is a convection microwave

A convection microwave is more sophisticated than a regular microwave and has many additional features apart from reheating and boiling. It uses both microwave technology and hot air circulation (convection) to cook food quickly and evenly. This enables users not only to reheat or defrost but also bake, roast, and grill, making it a versatile choice for efficient and convenient cooking.

Difference between a microwave and an OTG oven

Whether heating your food or baking cookies and cakes, a microwave oven and an OTG are both very helpful. However, based upon your usage, you can easily understand the difference between an OTG and a microwave oven. By knowing these differences, you can make the right decision to buy either of the two appliances for your kitchen.

Best for Baking, toasting, grilling Simple baking and defrosting

Can a microwave be used as an oven

The simple answer is yes. You can use your microwave as an oven, but it has to be a convection microwave. A microwave with a convection mode functions like any regular oven and can be used to bake bread, cakes, cookies, or anything else you would want to bake.

Factors to consider before a purchase

Before you shop for either an OTG or a microwave, consider these six aspects to decide what is best suited for your cooking needs:

Science behind cooking

When cooking with an OTG, the heat is radiated by the coils and absorbed by the food. A fan is present to distribute the heat, but most of the heat is dispensed directly below the coils. On the other hand, convection microwaves heat the water molecules present in food, thereby cooking it. A rotating plate and the microwaves ensure that the food is cooked evenly.

What to cook

An OTG is best used for baking, toasting, and grilling. For example, you can bake cakes, grill meat, and toast bread with ease. A convection microwave can perform all these functions and reheat, cook, and de-freeze as well, which an OTG cannot.


An OTG’s capacity may reach up to 60 litres, whereas convection microwaves reach a capacity of just 32 litres. So, for large batches of food, an OTG might be a better option. Additionally, the rotating surface in a microwave is relatively small, making it a problem to put large dishes on it. Moreover, though OTGs have larger capacities, they are much easier to handle owing to their lightweight.

Temperature range

The temperature range of both a convection oven and an OTG is almost the same, but the preheat time varies. While an OTG can take up to 20 minutes to preheat, the convection oven only takes 5 minutes. This can considerably decrease the cooking time.

Ease of use

Convection microwaves have a digital display, which allows you to keep track of the temperature and time easily compared to the knobs on an OTG.


The upfront cost of buying an OTG is around Rs. 10,000 for 42 litres, whereas a convection microwave costs around Rs. 16,000 for 30 litres. Although an OTG seems to be a cheaper option as it uses 20% less energy than a microwave oven, saving money in the long run.

Frequently asked questions

Is an OTG better than a convection microwave?

Choosing between an OTG (Oven Toaster Grill) and a microwave convection depends on your specific cooking needs. An OTG is ideal for baking, grilling, and toasting, offering better browning and crispiness. On the other hand, a microwave convection combines microwave and convection capabilities, allowing for baking, grilling, reheating, and defrosting. It offers faster cooking with even heating. Convection microwaves are versatile and efficient, while OTGs consume less energy. Consider your cooking preferences and the types of dishes that you make frequently before deciding which appliance suits you the best. Both options have their advantages, so choose based on your requirements.

Can a convection microwave work as an OTG?

Yes, a convection microwave can function as an OTG as well. Convection microwaves come equipped with both microwave and convection heating capabilities, making them versatile appliances for various cooking needs.

Can I use an OTG to reheat food?

Yes, you can use an OTG to reheat food. While it is primarily designed for baking, toasting, and grilling, an OTG can also be used to reheat leftovers or dishes.
