Difference Between OTG and Microwave Oven

Every kitchen has an Oven Toaster Oven (OTG) or a microwave. If you don't have one, your kitchen will appear incomplete. But, we get that choosing between a Microwave and an OTG can be a difficult task. So, here's everything you should know if you are thinking about buying one soon. To begin, there is a distinction to be made between an OTG and a microwave oven. Lets us get on the difference first!

What is an OTG, and How does it Work?

A smaller version of a typical oven is an Oven Toaster Grill (OTG). It cooks anything with heated coils and can reheat, grill, BBQ, keep meals warm, or bake. Depending on what you wish to cook, all OTGs have the choice to turn on one or both coils. You can prepare kebabs and grill food with the oven's rotisserie mode. Furthermore, an OTG can bake a cake perfectly. Cakes, cookies, muffins, pizza, bread, sourdough, tarts, rotisserie chicken, baked fish/chicken, baked veggies, kebabs, baked snacks such as baked samosas, baked cutlets, and more can all be made with an OTG.

What is a Microwave Oven?

As the name suggests, a microwave heats and cooks food by exposing it to microwave-frequency electromagnetic radiation. It generates thermal energy via a process known as dielectric heating, which is then utilized to heat meals. If you cook a range of dishes, a microwave is a good option.

Factors to Consider Before Buying a Microwave or an OTG

  • How much cooking would you do?

One of the most significant things to consider before purchasing an oven is how much cooking you will be doing. What you wish to cook will also be determined by the size of the oven. If you wish to roast or bake, you'll most likely need a larger oven. Purchase a smaller oven if you only use it sometimes.

  • Kitchen Space

Microwave ovens and OTGs come in a variety of sizes, so you'll need to figure out the amount of space you have in your kitchen to accommodate one. If you don't have adequate kitchen space, buying a large oven is pointless.

  • Electricity

Do you prefer an electric or a gas-powered oven? Determine how your oven will be powered in your kitchen. Then, depending on the same, choose an oven that best suits your needs.

  • Budget

What is the maximum amount you can spend on an oven? Also, think about the oven's energy efficiency. It would be a fantastic choice even if it is slightly more expensive upfront but saves you money in the long term.

  • Required Features

Do you want an oven that can roast and bake, one that heats food quickly, or helps you cook food more evenly? Consider all of the features and qualities you would like to see in an oven.  

Now, let at look at the differences between a Microwave oven and an OTG:

  • Differences in the USES:

Knowing what an OTG or a microwave oven is used for might help you decide whether or not you require one. An OTG's capabilities are restricted to baking, grilling, and toasting. You can't go wrong with an OTG if you want a specialized appliance for these three tasks or if you're into professional baking.

A microwave oven, on the other hand, a microwave oven is the best option if you want to create a variety of foods with a single piece of equipment. You may make various foods in a high-quality microwave oven, including cakes, pizza, muffins, pulao, chicken tikka, noodles, and rice. To put it another way, a microwave oven is a multi-purpose appliance.

  • Difference in TECHNOLOGY

An OTG works by heating the compartment within with nickel/chromium coils, then distributing the heat evenly with the help of a fan, replicating an actual charcoal oven. The coil’s temperature determines how much heat is generated, so pre-heating and thoroughly baking the dish takes time.

On the other hand, a microwave oven generates heat by absorbing electromagnetic waves absorbed by the food inside. These electromagnetic waves have a frequency range halfway between radio waves and infrared radiation.

  • Difference in Pre-heating TIME

An OTGs and microwave oven differ in food preparation and pre-heating time. Microwave ovens employ microwave heating, while OTGs use regular heatwave heating. As a result, microwave ovens are speedier than OTGs for food preparation and pre-heating. OTGs take roughly 14 to 15 minutes to heat, while newer microwave ovens only take 5 to 6 minutes to pre-heat.

  • Difference in SPACING

An Oven Toaster Grill (OTG) is equipped with racks that allow a number of trays to be placed on top of one another. In this way, you can easily bake many bread or cookies simultaneously. A turntable in a microwave, on the other hand, spins to cook the food uniformly. Only one thing can be used at a time in such an arrangement. Furthermore, unlike an OTG, a microwave cannot easily handle rectangular utensils.

  • Difference in UTENSILS USED

Aluminum, glass, and silicone utensils work well in an OTG. In contrast, plastic, silicone, and glass utensils work well in a microwave. On the other hand, metal utensils cannot be used in a microwave because water, fats, and sugars absorb electromagnetic waves. Still, they can be used in a conventional oven.

Pro tip: If you still cannot decide between a microwave and an OTG, choose a microwave with a conventional mode. In essence, this microwave oven comes with a heating coil pre-installed, similar to the ones seen on OTGs. In addition, multiple settings are available on convection microwave ovens, allowing you to heat or bake your food all in one product.
