Oven Toaster Griller (OTG) as the name suggests can toast, bake and grill but not defrost like a microwave oven this being the major difference between OTG and Microwave oven. An OTG has a built-in heating coil/rod in its cavity/cabinet which directly converts electric energy to heat energy.
An microwave oven (MWO) is described as a stainless steel rectangular box used to cook, defrost and heat. It converts electric energy into electromagnetic microwaves or radio waves and uses microwaves resonance to heat. This is the major difference between OTG and Microwave oven.
|OTG||Microwave Oven (Convection model)|
|Ideal for regular baking needs.||Ideal for multi-tasking cook needs.|
|There is no provision for auto-cook options.||Digital auto-cook option frees you and saves time.|
|Dedicated baking oven for baking, grilling and toasting only.||A multi-tasking cook machine that can heat, defrost apart from baking suits people with busy lives those who are amateurs.|
|Metal containers can be used to bake/heat inside the cavity.||Only silicone, ceramic and glass containers can be used.|
|The most ideal machine for baking like it’s made for baking, browning crisper foods.||Is not as much efficient in baking but could be the next best after an OTG for baking and roasting.|
|Inexpensive as compared to convection microwave ovens||Expensive and requires more maintenance.|
|Takes longer to cook or bake.||Does everything in minutes.|
|Consumes more energy, watch your electricity bill.||Energy efficient because it does not use electricity directly for heating.|
|Takes longer to heat.||Heats food in few seconds.|
The Verdict: An OTG is ideal for commercial baking/roasting or if you bake too often at home then you consider OTG vs Microwave Oven. A convection model microwave oven can multi-task for almost all cooking needs and is energy efficient but does not bake or roast as fine as an OTG.
