Modern Indian kitchens are increasingly crowded with countertop appliances. Air fryers promise crispy snacks with little oil, OTGs (oven, toaster, grill) open the door to home baking, and microwaves remain the fastest way to reheat leftovers. With limited counter space and a fixed budget, many families wonder which appliance they actually need, and whether one can replace the others.
This guide compares the three, explains what each does best and helps you choose based on how your household cooks.
How Each Appliance Works
Microwave ovens use microwaves to agitate water molecules in food, heating it quickly from within. Solo microwaves only reheat and cook; grill microwaves add a heating element for browning; convection microwaves add a fan and heater, allowing them to bake and roast as well.
OTGs use heating rods at the top and bottom, sometimes with a fan, to heat the air inside an insulated box. They work like a traditional oven and are well suited to baking, grilling and toasting.
Air fryers are compact convection ovens. A powerful fan circulates hot air rapidly around food in a basket, producing a crisp surface with far less oil than deep frying.
What Each Does Best
Microwave
- Reheating rice, dal, curries and leftovers in seconds.
- Defrosting frozen foods.
- Quick steaming of vegetables, making popcorn and simple dishes.
- Baking cakes and roasting, if it is a convection model.
OTG
- Baking breads, cakes, cookies and pizzas with even browning.
- Grilling paneer or chicken tikka, kebabs and vegetables.
- Larger batches thanks to bigger capacities.
Air fryer
- Crispy snacks such as samosas, cutlets, fries and pakoras with minimal oil.
- Quick roasting of vegetables, peanuts and makhana.
- Reheating fried foods while keeping them crisp, something microwaves cannot do.
- Small portions for one to three people with fast preheating.
Health Considerations
Air frying can significantly reduce the oil used compared with deep frying, which helps families looking to cut fat and calories in snacks. However, an air-fried samosa is still a samosa; the healthiest gains come from using the appliance to roast vegetables, paneer, legumes and lean proteins rather than simply replacing one indulgent snack with another. Microwave cooking can retain nutrients well when vegetables are cooked quickly with little water. Use microwave-safe glass or ceramic containers rather than ordinary plastics for heating food.
Electricity Use and Speed
Appliance wattage varies widely, but cooking time matters as much as power rating. Microwaves are typically the most energy-efficient for reheating small quantities. Air fryers preheat quickly and cook small portions fast, making them efficient for snacks. OTGs need longer preheating and cooking times, so they consume more energy for small tasks but are practical for larger bakes. Check your home’s wiring and sockets can handle high-wattage appliances, and avoid running several at once on the same circuit.
Space and Capacity
Measure your counter before buying. Air fryers are compact but tall, and baskets typically range from small single-person sizes to family capacities of five litres or more. OTGs range from small units to large ovens over forty litres. Microwaves come in sizes around twenty to thirty litres for most homes. Leave space around appliances for ventilation, since all of them release heat.
Which Should You Buy?
Choose a microwave first if your household reheats food daily, you want fast defrosting, and you value convenience over crispness. A convection microwave adds baking ability, making it a versatile all-rounder for small kitchens.
Choose an OTG if you love baking, want to grill tikkas and pizzas, or cook for larger groups regularly.
Choose an air fryer if you want healthier versions of fried snacks, cook small portions and value speed and easy cleaning.
Many families find the most practical combination is a microwave for reheating plus either an air fryer or an OTG, depending on whether they prefer snacks or baking.
Features Worth Paying For
- Accurate temperature control and a reliable timer with auto shut-off.
- Non-stick, dishwasher-safe baskets or trays that are easy to clean.
- Preset Indian menus can be helpful but should not be the deciding factor.
- Warranty and service availability, since heating elements and fans can fail.
- Safety certifications and stable, cool-touch exteriors in homes with children.
Features You Can Skip
Dozens of presets, app connectivity and digital gimmicks add cost without improving cooking for most families. Simple, reliable controls usually serve better over years of use.

Budgeting and Buying Tips
Prices for all three appliances fluctuate heavily during festive sales, so planning a purchase around major sale events can bring meaningful savings. Compare models on capacity, wattage, warranty length and the availability of spare parts such as baskets and trays. Read recent customer reviews for reports of coating peeling, uneven heating or fan noise, which often appear only after months of use. Buying from an authorised seller protects your warranty, and keeping the invoice makes service claims straightforward.
Care and Maintenance Tips
- Clean baskets, trays and turntables after every use to prevent smoke and odours.
- Avoid metal scrubbers on non-stick coatings.
- Wipe interior walls regularly to stop grease build-up.
- Never run a microwave empty, and never use metal containers in it unless the manual allows.
- Unplug appliances when not in use for long periods.
Common Myths
- “Air fryers fry food.” They roast with hot air; results are crisp but not identical to deep frying.
- “Microwaves destroy all nutrients.” Quick cooking with little water can actually preserve nutrients well.
- “An OTG and a convection microwave are the same.” They overlap, but OTGs usually brown and bake more evenly, while convection microwaves add speed and reheating ability.
Conclusion
No single appliance does everything perfectly. The right choice depends on what your family cooks most: quick reheating, baking and grilling, or crispy low-oil snacks. Match the appliance to your habits, space and budget, and it will earn its place on your counter for years. For more practical guidance on home appliances and smart buying decisions, visit Tachlein.
