Solo vs Grill vs Convection Microwave: Which to Buy

Microwave marketing in India is built around feature counts — 200 auto-cook menus, ten power levels — when the only decision that actually matters is which of three fundamentally different appliances you are buying. Get that right and the rest is detail.

The three types

Solo

A solo microwave does one thing: it emits microwaves that agitate water molecules in food, heating it from within.

What it does well: reheating cooked food, boiling milk and water, defrosting, steaming, cooking rice and dal, melting butter or chocolate.

What it cannot do: brown, crisp or bake anything. A roti reheated in a solo microwave comes out soft and steamy, never crisp. There is no dry heat, so there is no browning reaction.

Who it is for: households where the microwave’s job is reheating. That is the large majority of Indian homes, and a solo microwave does that job exactly as well as a model costing three times more.

Grill

A solo microwave plus a heating element, usually at the top of the cavity.

What it adds: browning and crisping on the surface. Grilled paneer, kebabs, cheese toast, a crisped top on a baked dish.

What it still cannot do: bake. The grill element heats from one direction without circulating air, so it cannot hold an even cavity temperature. Cakes will not work.

Who it is for: a narrow band of buyers who specifically want grilling and definitely will not bake. In practice the price gap to convection is often small enough that this type is hard to recommend — check both before deciding.

Convection

A solo microwave, plus a heating element, plus a fan that circulates hot air — which is what makes it a genuine oven.

What it adds: even dry heat throughout the cavity. Cakes, cookies, bread, roasted vegetables, roast chicken. It can also combine microwave and convection modes to cook faster than either alone.

The costs: roughly double the price of a solo model, a larger footprint, and eight to ten minutes of preheating whenever you bake.

Who it is for: anyone who will actually bake or roast. The word actually is carrying weight there.

The honest question to ask yourself

Convection microwaves are bought on aspiration and used on habit. The pattern is familiar: bought with baking in mind, used enthusiastically for a month, then used as a solo microwave for the next eight years.

If you already bake in an OTG or a pressure cooker, you will use a convection microwave. If you have been meaning to start baking for three years, be sceptical — and consider buying a solo microwave now and an OTG later, which will cost about the same combined and bake better.

Capacity, which matters more than people expect

Stated capacity is cavity volume, and usable space is less than the number suggests because the turntable and walls need clearance.

• 20L — adequate for one or two people reheating. Too small for a full dinner plate in some models, so check.
• 25–28L — the sweet spot for a family of three to five. Fits a standard dinner plate comfortably and a small baking tray.
• 30L and above — worth it for large families or serious baking. Takes real counter space.

For a convection model, do not go below 25L. Baking in a 20L cavity means tiny trays and uneven results.

Features worth paying for, and not

Worth it: a ceramic or stainless cavity. Ceramic enamel interiors wipe clean and resist the staining that plagues painted cavities. On an appliance splattered with dal weekly, this is the feature you will appreciate most.

Worth it: a clearly marked power level control. Reheating rice at full power makes it rubbery. Most people never find the power setting because it is buried in a menu.

Not worth it: auto-cook menu count. “251 auto-cook menus” means 251 preset time-and-power combinations calibrated for quantities that are probably not yours. Most people use two or three and ignore the rest.

Not worth it: inverter technology, mostly. It provides more consistent low-power output, which is genuinely better for delicate defrosting. It is not worth choosing a lesser appliance to get.

Practical notes for Indian kitchens

Ventilation. Microwaves vent heat from the back and sides. Built into a tight cabinet with no clearance, they overheat and shut off. Leave the clearance the manual specifies.

Metal and convection mode. In convection mode a microwave is an oven, so metal trays are fine. In microwave or combination mode they are not. Mixing these up is the most common way people damage a convection microwave in the first month.

Voltage. Microwaves draw significant current and are sensitive to low voltage. In areas with unreliable supply, a stabiliser is sensible.

The short answer

Reheating food, boiling milk, defrosting? Buy a solo microwave, 20–25L. Spend the savings on something you will use.

Will genuinely bake and roast? Buy a convection microwave, 25–28L, with a ceramic cavity.

Want grilling but definitely not baking? Check the price gap to convection first. It is frequently small enough that grill-only stops making sense.

Frequently asked questions

Can a convection microwave replace an oven for baking?

For cakes, cookies, small breads and roasting vegetables, yes — a 28L convection model does this well. For large quantities, artisan bread needing steam, or anything requiring a big tray, a dedicated oven is still better.

Is a solo microwave enough for a small family?

If you mainly reheat food, boil milk and defrost, absolutely. A solo microwave does those three jobs as well as any convection model and costs a third as much. Only pay more if you will actually grill or bake.

Why do convection microwaves take so long to preheat?

They use a heating element and fan to warm the whole cavity, the same as a conventional oven, and the cavity is metal. Expect eight to ten minutes. The microwave function itself is still instant.
