Difference Between OTG and Microwave Oven: A Comparative Guide

In the debate between ‘OTG vs microwave’, some emphasize that an OTG is a crucial tool for baking, while others point out the convenience and simplicity offered by a microwave. In this article, we will understand the difference between OTG and microwave oven and analyze the benefits of both appliances and how their distinct features cater to individual requirements.

What is an OTG and How it Works?

An OTG, which stands for “Oven, Toaster, Griller,” is a kitchen appliance used for baking, toasting, and grilling food. It works by using metal coils to convert electricity directly into heat. These coils generate the required temperature for baking or grilling inside the oven’s cooking chamber. The compact and portable design of an OTG makes it a convenient option for various cooking tasks. Its metal coils ensure thorough and even cooking of the food.

What is a Microwave Oven and How it Works?

A microwave oven is a kitchen appliance that cooks or heats food using microwave radiation. It emits microwaves that penetrate the food. This causes water molecules to vibrate and generate heat, which cooks the food quickly and evenly. For safe and effective cooking, the oven confines the microwaves within its cooking chamber.

What is the Difference Between OTG and Microwave Oven?

The primary differences between an OTG (Oven, Toaster, Griller) and a microwave oven lie in their functionality, cooking methods, and the types of dishes they are best suited for.

1. Working Mechanism

An OTG uses metal coils to convert electricity directly into heat. This heat is then radiated into the oven’s cooking chamber, allowing for baking, grilling, and toasting of food items. It’s particularly effective for recipes that require browning or crisping.

A microwave oven emits microwaves that penetrate the food and cause water molecules to vibrate. This vibration generates heat, which cooks the food from within. Microwaves are excellent for quickly reheating and cooking food, but they might not provide the same level of browning or texture as an OTG.

2. Cooking Applications

An OTG is well-suited for baking cakes, cookies, and bread. It’s also great for grilling vegetables and meats and making toast. The direct heat from the coils helps achieve a desirable texture and color.

A microwave oven is ideal for reheating leftovers, defrosting frozen foods, and cooking items that don’t require browning. It’s quicker than an OTG for tasks like warming beverages or heating pre-cooked meals.

3. Texture and Results

Food cooked in an OTG often has a crispier and browned exterior due to the direct radiant heat. It’s better for achieving the golden crust on baked goods and grilled dishes.

Food cooked in a microwave might lack the same level of browning and texture due to the absence of direct radiant heat. However, it excels at evenly heating food and preserving moisture.

4. Convenience

OTGs are versatile but might require more time for cooking and preheating. They are typically larger and less portable.

Microwaves are extremely convenient for rapid reheating and quick cooking. They are compact, energy-efficient, and suitable for smaller kitchens.

5. Cookware Compatibility

An OTG can use a variety of baking and grilling trays, pans, and molds made of metal, glass, or ceramic. This allows for versatile cooking and baking.

Microwave-safe containers made of glass, ceramic, or microwave-safe plastics are recommended. Metal utensils or cookware with metallic elements should be avoided as they can cause sparks in a microwave.

6. Cooking Time

Cooking with an OTG can take a bit more time because of preheating and how heat spreads. Microwaves cook faster since they create heat directly inside the food.

7. Uniform Heating

When you use an OTG to cook, you might notice that the heat isn’t spread evenly, especially for larger items or multiple trays. On the other hand, Microwave Ovens tend to heat food more evenly overall, which reduces the chances of having parts that are not cooked the same way.

8. Crisping and Texture

The direct radiant heat emitted by an OTG’s coils is effective in achieving crispy and crunchy textures, whereas microwave ovens might result in softer textures. However, microwaves excel in preserving moisture and preventing over-drying, contributing to the appeal of certain dishes.

9. Types of Food

OTGs work well for foods that need browning, like baked goods, roasted meats, and casseroles. Microwaves are great for heating liquids, steaming veggies, and quickly cooking or reheating pre-cooked meals.

10. Energy Consumption

OTGs tend to consume more energy due to their longer cooking times and the need for preheating. On the other hand, Microwave Ovens are more energy-efficient, particularly for quick cooking and reheating tasks, thanks to their shorter cooking durations.

Difference Between OTG and Microwave Oven Prices

In general,  OTG appliances are typically less expensive than microwave ovens. OTGs are designed for basic baking, toasting, and grilling tasks. Microwave ovens offer more versatile features, including reheating, defrosting, and cooking, and, are costlier than the OTGs. However, prices can vary based on factors such as brand, features, and location.

Which is Healthier: OTG or Microwave Oven?

Ultimately, the decision between an OTG and a microwave oven depends on your cooking habits, preferences, and the types of dishes you frequently prepare. Both appliances have their strengths and limitations, so it’s important to choose the one that aligns with your culinary needs.


OTGs use dry heat to cook food. They are commonly used for baking, toasting, and grilling. OTGs can be a healthier option for certain types of cooking, especially when it comes to baking items like bread, cakes, and roasted vegetables. Baking and grilling can help retain nutrients and flavors in food. However, using excessive oil or fats in grilling can negate some of the health benefits. When using an OTG, you have more control over the ingredients and can choose healthier cooking methods.

Microwave Oven

Microwave ovens use microwave radiation to heat food. They are particularly efficient for reheating and defrosting, as they heat food quickly and evenly. Microwaving can help preserve more nutrients in some foods compared to traditional cooking methods because of the shorter cooking times and minimal use of water. However, microwaving certain foods in plastic containers or using materials not labeled as microwave-safe can potentially release harmful substances into your food. It’s important to use microwave-safe cookware and avoid overcooking, as prolonged high-heat exposure might lead to nutrient loss.

Both OTGs and microwave ovens can be used in healthy cooking, depending on how you use them and the type of food you’re preparing.

Conclusion: Difference Between OTG and Microwave Oven

In summary, choosing between an OTG (Oven, Toaster, and Griller) and a microwave oven depends on your cooking priorities. The OTG’s baking and grilling capabilities offer nutrient retention and controlled cooking, ideal for health-conscious individuals seeking flavorful yet healthful meals. Meanwhile, the microwave’s efficiency in reheating and quick cooking preserves nutrients in shorter durations, especially beneficial for vegetables and meats. Ultimately, incorporating both appliances smartly into your kitchen routine, while prioritizing nutrient-rich ingredients and sound cooking practices, can lead to a well-rounded and health-conscious approach to meal preparation.
