Difference Between Microwave And OTG - (Definition, Comparison & Conclusion)

OTG VS Microwave

Hey there, you may be here out of two reasons, one – you are extremely in love with cooking and baking or two - you want to collect some general information on OTG vs Microwave. Well, in both cases you will be served rich information on difference between Microwave and OTG on this page.

You get to access so many articles and videos in blogs and YouTube about baking and stuff, and when you see other people baking their own cake at home, you also motivate yourself to bake a cake at home using oven however, this is the exact point where you get stuck.

Most of the people are not aware of what to use when baking a cake. While on the flip side, there are people who know that OTG is much more effective than the regular microwave but are not completely aware of the differences. So, the million-dollar question that arises now is – What is the difference between Microwave and OTG ?

Microwave and OTG may look similar and do the same work but there are some basic differences which you must know. Now, the difference between Microwave and OTG can be on several factors including technology, inner spacing, cost, ease of use, etc. So, in this article, we will discuss all the factors and cover the topic of OTG vs Microwave.

So, now without further ado let us look at each of them separately and then proceed with the comparison.

What Is Microwave ?

Microwave oven (commonly known as a microwave) is a kitchen appliance that helps to cook and heat food by the means of electromagnetic waves aka 'microwaves'. It raises the temperature of the food by exposing it to high-frequency electromagnetic field.

Microwaves are popular for baking cakes and roasting foods and they do this very quickly. This means the microwave oven is your best companion when you are in a hurry.

  • How Does It Work ?

The most common wave frequency in a microwave oven is roughly 2,450 megahertz which are absorbed by fats, water and sugar (already present in food). Once the waves are absorbed, they are converted into heat.

This heating takes place inside the food item without affecting the surrounding air. This is the key to fast heating and reducing the cooking time in a microwave oven.

NOTE: Waves frequency have a property and that is – they are not absorbed by glass, plastic or ceramics.

  • Properties Of Microwave

  1. The heating in microwaves occurs by the process of absorption so it tends to heat and cook certain foods unevenly.
  2. The moist foods tend to cook faster than less moist food in the microwave oven.
  3. The outer layer of food may not turn brown or crispy.
  4. In a microwave oven, there are some materials that can absorb wave frequency, it includes metal vessels.

What Is OTG ?

Oven, Toaster, and Grill is the full form of an OTG. As the name suggests, it has three properties that can be a very convenient appliance in the kitchen. OTG uses heat coils to heat and cook’s food. The thermostats in the OTG can help you control the temperature inside and cook the food properly.

  • How Does It Work ?

OTG has the heating element that includes chromium/nickel coil to heat the compartment and a fan that helps to distribute heat evenly. This not only cooks the food but also help to provide baking and browning effect.

  • Properties Of OTG

  1. The heat within the compartment comes from the coil’s temperature so it typically takes time for pre-heating.
  2. The main and perhaps best feature is the fan that circulates heat around the food that helps to cook the food properly.
  3. An OTG can bake, grill and toast but cannot defrost and cannot be used for heating purposes.

Now, that you have learned some basics about what a microwave oven and an OTG is, how it works, and what properties they tend to possess, it is time for you to finally understand the difference between microwave and OTG.

Microwave Vs OTG

As we know now, both microwave and OTG are almost used for common purposes but they do have some differences. So, in order to make the comparison convenient and easy to digest we will have to discuss some factors that both devices share.

1. Technology

Microwave – It uses electromagnetic waves. Food items contain fats, water, and sugars which absorbs these waves and convert into heat. The heat in microwaves is unevenly distributed and the pre-heating feature here quickly heats or cooks the food.

OTG – Oven, Toaster and grill (OTG) comes with heat coils within the compartment and fans. In OTG pre-heating takes much time than a microwave but it tends to cook the food properly due to the fans. Fans evenly distribute the heat around the food.

2. Temperature

The temperature range in a microwave and an OTG is almost same, you can set the temperature in both the devices over 100 C. You don’t have to worry on this count.

3. Pre-Heating

It is the process where you heat the oven before actually cooking the food. It helps to cook food much faster. Though the temperature range does not vary, microwave and OTG definitely varies in pre-heating.

Microwave – Microwaves may typically take 5 minutes to preheat.

OTG – OTG may typically take 10 to 15 minutes to preheat, which is more in comparison to microwave.

4. Inner Spacing/Capacity

Microwave – The capacity of microwave can reach up to 42 liters. Talking about inner spacing, the rotating disc/plate in the microwave is quite small which does not allow to put large dishes.

OTG – The capacity of OTG can range from 15 Lt. to 60 Lt.. In terms of inner spacing, OTG comes with multiple racks installed where you can access trays and slide them one on top of the other.

5. Utensils (Bakeware)

Microwave – There are few utensils like silicon, Paper, glass, Styrofoam, ceramics, and tempered glass (Pyrex) that are used in the microwave and are perfect options. However, metal utensils should be avoided because they do not absorb electromagnetic waves and cause short-circuit which can be really risky or dangerous.

OTG – Utensils like non-reactive metal vessels, glass (borosilicate glass), silicon are some of the perfect options for OTG.

6. Features

OTG normally comes with a feature called – Timer Bypass Switch or Stay On. This switch allows you to keep the oven switched ON till you are ready to turn it OFF manually. This feature is useful and comes in handy when you want to bake meringues or cook some oven-dried tomatoes.

This feature is not available in the microwave oven. But you don’t have to worry about it unless you are making meringues or oven-dried tomatoes every day.

7. Functionality

Microwave – In microwave, you can cook, reheat, grill, de-freeze, and bake.

OTG – Whereas, in an OTG you could toast, grill and bake your food but it does not allow you to re-heat or de-freeze.

8. Ease Of Use

Microwave – In microwave, the controls and display are mostly digital.

OTG – In OTG, you will always get the manual controlling system. While using this device you will have to be precise with your timer because unlike microwave you don’t have any display timer in OTG.

Microwave are much easy to use because they have only one rack plus they have single mode for baking. Whereas OTG has multiple racks so you will need to figure out which one is the best option for you, moreover, OTG has multiple baking and heating element modes.

9. Weight

Microwave is much heavier in comparison to OTG, which means you will have to find a permanent place for keeping your microwave but you can move your OTG anywhere you feel comfortable.

10. Price

Microwave – You can get 20- or 30-liters capacity microwave in 10000 to 15,000 rupees.

OTG – The cost of OTG is lesser than microwave, you can easily get 30- or 42-liters capacity OTG in 5,000 to 8,000 rupees.

11. Power Consumption

Microwave can save up to 20% energy in comparison to OTG, which clearly means, for the long term you can choose a microwave.

There you go, these are the things that you must consider before baking your food items or before purchasing. There is no clear winner in this comparison because both have some of the other qualities that can be seen both as an advantage or a disadvantage.


Let us recap what we’ve learned in this article – it can be a little confusing when you have to choose between Microwave and OTG.

Microwave are amazing kitchen appliances to reheat, grill or even bake. They are helpful in cooking a wide range of recipes and food items including chicken, popcorn, kebabs, and pizza and heat frozen food. On the other hand, OTG (oven, toaster, and grill) are exclusively used to bake, grill and toast.

The bottom line here is, if you want to cook basic recipes like rice, chicken, curries and want to do it quickly you can go for conduction microwave. But, if you are a professional baker or looking for dedicated kitchen appliances only to bake, toast and grill with the world-class baking quality then OTG is your right option for you.

In order to take your cooking and baking game to the next level, you can include both microwave and OTG in your cabinet. This is it, hope you find the article informative and you have learned the difference between Microwave and OTG.
