Choosing between a Microwave and an OTG Oven can be confusing, especially when upgrading your kitchen. While both appliances look similar, they serve different purposes. A microwave uses electromagnetic waves to quickly heat and cook food, making it perfect for reheating, defrosting, and simple cooking. An OTG Oven, on the other hand, uses heating elements for baking, roasting, and grilling, giving your dishes that perfect golden finish.

Before making your purchase, check your Insta EMI Card eligibility to know your spending limit. Once you have your budget ready, explore the latest microwave and oven models online or at any of Bajaj Finserv’s 1.5 lakh partner stores across 4,000+ cities. Convert your purchase into Easy EMIs of up to Rs. 3 lakh with zero down payment on select models and enjoy a hassle-free kitchen upgrade.

What's the difference between microwave and oven?

Before deciding which appliance suits your kitchen better, understanding the fundamental differences between microwave and oven is essential:

Feature Microwave Convection oven

What is a microwave?

A microwave is a kitchen appliance that cooks food using electromagnetic radiation. These waves cause water molecules in food to vibrate, creating friction and heat. Most Indian households use microwaves for quick reheating of leftovers, defrosting frozen items, or making simple dishes like popcorn. Modern microwaves come with additional features like grill or convection functions that expand their cooking capabilities.

What can you cook with a microwave?

Microwaves offer convenience for several cooking tasks:

  • Reheating leftovers: Warm up yesterday's dal or rice in just 1-2 minutes without drying it out
  • Defrosting frozen foods: Thaw frozen vegetables or meat quickly without cooking them
  • Making hot beverages: Heat water for tea or milk for coffee in under a minute
  • Cooking vegetables: Steam broccoli, peas, or carrots while retaining nutrients
  • Preparing ready-to-eat meals: Cook instant noodles, ready-to-eat packets, or microwave popcorn
  • Making simple desserts: Prepare mug cakes or puddings in minutes

What are the advantages of cooking with a microwave?

Microwaves offer quick cooking, energy efficiency, and space-saving benefits. They are perfect for busy Indian households where quick meal preparation is essential. Their simple controls make them accessible for all family members.

Size

Microwaves are compact kitchen appliances that fit comfortably on most countertops. Standard models measure about 45-60 cm in width and 30-45 cm in height. This compact size makes them ideal for small Indian kitchens where space is often limited. Some models are designed to be mounted under cabinets, saving even more counter space. Their small footprint does not compromise functionality for quick cooking tasks.

Speed of cooking

Microwaves cook food remarkably fast compared to conventional methods. While a traditional oven might take 30 minutes to bake potatoes, a microwave can cook them in 5-8 minutes. This speed comes from the direct heating of food molecules rather than heating the surrounding air. For busy Indian families, this time-saving feature is invaluable, especially during hectic mornings or when preparing quick meals after work.

Price

Microwaves are generally more affordable than convection ovens. Basic models start from Rs. 5,000, while feature-rich options may Rs. 20,000 or more. With the Bajaj Finserv Insta EMI Card, you can purchase a quality microwave and spread the cost over comfortable EMI tenures. You may already be eligible for a pre-approved offer – check instantly by entering your mobile number and OTP.

Method of cooking

Microwaves cook food using electromagnetic radiation that targets water molecules. This radiation causes these molecules to vibrate rapidly, creating friction and heat. Unlike conventional cooking methods, microwaves heat food from within rather than from outside inward. This method is excellent for reheating without drying out food and for quick cooking tasks, though it cannot brown or crisp food surfaces.

Effects on food

Microwave cooking preserves more nutrients in vegetables than many cooking methods because of shorter cooking times and minimal water usage. However, it does have limitations. Food cooked in microwaves retains moisture but lacks the browning or crisping that enhances flavor in many dishes. Textures can also differ, with some foods becoming softer rather than developing the crispy exterior that oven cooking provides.

What is a convection oven?

A convection oven uses heating elements to warm the air inside, while fans circulate this hot air evenly around the food. This circulation ensures consistent cooking temperatures throughout the oven cavity. Convection ovens are versatile kitchen appliances that excel at baking, roasting, and browning food. They require preheating but deliver superior results for complex cooking tasks that need even heat distribution.

What can you cook with a convection oven?

Convection ovens excel at numerous cooking tasks:

  • Baking breads and cakes: Create perfectly risen, evenly browned bread loaves, naan, or celebration cakes
  • Roasting meats: Prepare tender, juicy chicken, mutton, or fish with a delicious browned exterior
  • Cooking traditional dishes: Make tandoori-style foods or dishes that require consistent heat
  • Baking cookies and biscuits: Bake multiple trays of perfectly browned cookies at once
  • Preparing casseroles: Cook layered dishes with even heat throughout
  • Roasting vegetables: Achieve caramelised, flavourful vegetables with crisp exteriors

What are the advantages of cooking with a convection oven?

Convection ovens provide versatility for various cooking techniques, achieve better browning, and allow for cooking multiple dishes simultaneously. They excel at traditional baking tasks and create professional-quality results for both everyday meals and special occasions.

Size

Convection ovens are substantially larger than microwaves, requiring dedicated space in your kitchen. They typically measure 60-75 cm in width and 60 cm in height for built-in models. Countertop versions are available but still occupy significant space. This larger size accommodates bigger dishes and multiple trays, making them suitable for cooking family meals or entertaining guests during festivals and celebrations.

Speed of cooking

While slower than microwaves, convection ovens cook faster than traditional ovens. The fan-circulated hot air reduces cooking time by approximately 25%. A cake that might take 40 minutes in a conventional oven could be ready in 30 minutes in a convection oven. This efficiency comes from the even heat distribution, eliminating hot and cold spots that can affect cooking time.

Price

Convection ovens represent a higher investment than microwaves. Entry-level models start around Rs. 10,000, while premium built-in versions can exceed Rs. 50,000. The Bajaj Finserv Insta EMI Card makes these appliances more accessible by converting the purchase amount into affordable monthly payments. Check your pre-approved offer today with just your mobile number and OTP verification.

Method of cooking

Convection ovens cook food through the circulation of heated air. Powerful fans distribute hot air evenly throughout the oven cavity, surrounding food with consistent heat. This method excels at browning and crisping food surfaces while cooking the interior thoroughly. The even heat distribution eliminates the need to rotate dishes during cooking and allows for multiple items to cook uniformly across different racks.

Effects on food

Food cooked in convection ovens develops appealing textures and flavours. The circulating hot air creates a wonderfully crisp exterior on roasted meats while sealing in juices. Baked goods rise more evenly and develop golden-brown crusts. The dry heat environment caramelises sugars in foods, enhancing flavours. These qualities make convection ovens ideal for preparing traditional Indian dishes that require precise browning and texture development.

Microwave vs convection oven: Making the right choice
