OTG vs Microwave Oven

OTG and Microwave ovens are two excellent kitchen appliances that are extremely important to certain people because they are used to bake and cook numerous meals during the day.

But many individuals, are unaware of how different they are! Once you have a thorough understanding of the appliances, you will be able to decide which one to purchase.

Despite the fact that these goods appear to be identical and conduct the same type of work, they can have major distinctions. Today, we’ll look at the difference between OTG and Microwave oven so you can figure out one is right for you.

What is ‘OTG Oven’?

Microwave Oven vs OTG

The full form of OTG Oven is ‘Oven, Toaster, Grill’. The OTG (Oven, Toaster, Grill) is a small version of a conventional oven. As the name indicates, you can also bake, toast, and grill in it.

However, the majority of them lack the ability to reheat, cook, or defrost. Heated coils are used to cook dishes in this sort of oven. The thermostat and the fan within, help to spread the heat and manage the temperature.

A heating coil regulates the temperature in an OTG. This coil can be located on the device’s top and bottom, ensuring even heat transfer. A thermostat allows you to choose how much heat you desire.

The coils convert electricity into heat, which you may aim in whatever direction you want. For example, if you want to learn how to bake with an OTG oven, For example, if you want to bake a cake in an OTG oven, you’ll need to heat both the bottom and top coils.

Also, if you want to grill some food, just turn up the top coil. Temperature knobs and Automatic timers, as well as other knobs that let you to switch between specific functionalities, are included in today’s OTGs.

OTG ovens can be used for reheating food and toasting bread in addition to baking cakes and pastries and grilling meats.

Have you ever observed that heating takes longer than that of a microwave? This is due to the fact that the electric coils require time to warm up. As a result, the cooking time increases.

What is Microwave Oven?

Microwave Oven vs OTG

Electromagnetic waves are used in microwave ovens, and these waves are absorbed by the food. These electromagnetic waves have a frequency range of 300 MHz to 300 GHz and include radio waves and infrared radiation.

In comparison to OTG, the pre-heat time is less. Instead of a fan, there is a plate that revolves to ensure that food is cooked uniformly.

When you place food in a microwave oven, the microwaves are directed toward the food, and after absorption, the energy is converted to heat.

The heat then radiates outward, heating the rest of the food as well. Microwave ovens are ideal for quick cooking and reheating. The microwave oven takes pride in its “instant” cooking/baking label. Idlis, dhoklas, pastries, mug pizzas, quick mac n cheese, instant omelet, and more! Oh, my goodness!

Difference Between OTG and Microwave Oven

Both microwave and OTG are now almost regularly used for similar reasons, although there are notable distinctions. So, in order to make the comparison more convenient and understandable, we’ll go through some of the similarities and differences between the two devices.


Electricity is used to power both ovens. However, the way these devices receive and utilize power is a little different.


In an OTG, electricity is used to heat up certain nickel or chromium coils. The heating components then evenly distribute heat throughout the oven’s capacity, finally cooking the food inside.

However, when compared to microwave ovens, one of the biggest disadvantages of OTGs is that food takes longer to cook.

Microwave Oven

The microwave oven distributes heat evenly throughout your meal by using waves of electromagnetic radiation. In some circumstances, you can have your food ready to eat in just minutes.

When you’re pressed for time and only have a few minutes, the microwave is a fantastic choice. The temperature in a microwave is normally controlled automatically.


The temperature range of an OTG and a microwave is nearly the same; both devices can reach temperatures of above 100 degrees Celsius. You don’t have to be concerned about this.


It’s the activity of preheating the oven before cooking the food. It speeds up the cooking process. Though the temperature range is consistent, OTG and microwave pre-heating differs significantly.


In comparison to the microwave, OTG normally takes 10 to 15 minutes to preheat.

Microwave Oven

Preheating a microwave can take up to 5 minutes.

Utility (Baking and Cooking Time)


An OTG bakes, toasts, grills, and broils meals. In an OTG, there is no actual “cooking.”

A recipe’s baking time will be the same in both ovens. Cooking times will vary. Also, OTGs don’t have the ‘Auto Cook Menu’ options.

Microwave Oven

When it comes to cooking, a microwave oven cooks food more faster than an OTG. In addition, modern microwave ovens, such as this one, feature distinct grilling and air-frying/low-oil frying modes.

In addition, some microwave ovens, such as this one, have fascinating auto-cook menu options that allow you to cook food with pre-set cooking time and temperature settings.



OTG has a capacity ranging from 15 to 60 litres. In terms of inner spacing, OTG has many racks where trays can be accessed and stacked one on top of the other.

Microwave Oven

Microwaves have a capacity of up to 42 litres. When it comes to interior spacing, the microwave’s rotating disc/plate is quite small, making it impossible to fit large dishes inside.



Non-reactive metal containers, glass (borosilicate glass), and silicon are all good choices for OTG.

Microwave Oven

Silicon, paper, glass, Styrofoam, ceramics, and tempered glass (Pyrex) are just a few of the utensils that can be used in the microwave and are excellent choices.

Metal utensils, on the other hand, should be avoided since they do not absorb electromagnetic radiation and might cause a short-circuit, which is quite dangerous.

Inner Spacing


An OTG, is equipped with racks that allow many trays to be stacked on top of one another. In this manner, you can easily bake many batches of bread or cookies at the same time.

Microwave Oven

A Turntable in a microwave, spins to uniformly cook the food. Only one thing can be placed at a time in such an arrangement.

Furthermore, unlike an OTG, it cannot easily handle rectangular dishes.



While an OTG allows you to toast, grill, and bake your food, it does not allow you to reheat or defrost it.

Microwave Oven

You can cook, reheat, grill, defrost, and bake in the microwave.

Ease Of Use


The manual controlling system is always available in OTG. Because, unlike the microwave, the OTG does not have a display timer, you will have to be accurate with your timer when using it.

OTG has various racks, so you’ll have to figure out which one is perfect for you. It also has several baking and heating element modes.

Microwave Oven

Microwaves are significantly easier to use because they only have one rack and a single baking option.

The settings as well as display in a microwave are mostly digital.


Because the microwave is considerably heavier than the OTG, you will need to locate a permanent location for it, whereas the OTG may be moved wherever you like.



OTG is less expensive than a microwave; you can acquire a 30- or 42-liter OTG for 5,000 to 8,000 rupees.

Microwave Oven

A microwave oven with a capacity of 20 or 32 litres costs between 10,000 and 20,000 rupees.

Power Consumption

In comparison to OTG, microwaves can save up to 20% energy, indicating that microwaves are the better option in the long run.

That’s all there is to it when it comes to things to think about before buying Microwave oven or OTG.
