Microwave vs. Convection Microwave: Which is Better?

A microwave can do simple cooking tasks, quick heating of leftovers, and water boiling in 1-2 minutes depending on how much water you need to boil. A convection microwave, on the other hand, does all those things and can distribute heat by convection using convection fans.

Percy Spencer invented the microwave—which he patented and sold as “Radarange”—after noticing his chocolate bar melt in his pockets while being near radar equipment. Meanwhile, the conventional oven found a way to cut down preheating and cooking times by incorporating the convection fan.

So the marriage of the convection oven and the microwave seems like a natural progression. However, which of the two inventions— microwave vs convection microwave —is better?

Microwave vs. Convection Microwave

A microwave oven uses microwaves or short-frequency radio waves in order to excite the water molecules found inside food to a boiling or near-boiling temperature, which then leads to instantaneous cooking in minutes.

A convection oven, meanwhile, works like a traditional oven using heating elements to roast, grill, or bake food but requires a bit of preheating in order to reach the desired cooking temperature. The convection heat part comes from the convection fans that circulate the heat better.

Specializes in Quick Heating Food

Both the microwave oven and the convection oven specialize in quickly heating up food, but while the microwave oven works inwards then outwards the dish, the convection oven instead roasts food outwards then inwards.

A convection microwave combines both the microwave oven’s magnetron that transmits microwave radiation and the convection oven’s heating element and convection fans to do convection heating.

What’s a Microwave Anyway?

A microwave has a magnetron inside that emits microwave radiation or short-frequency radiowaves that affect the food’s water content. The water molecules vibrate to the point of producing thermal energy care of friction, which in turn raises its temperature to the boiling point.

This also cuts down heating time by 1-3 minutes versus the 5 minutes required to preheat a convection oven and the 15-20 minutes required to preheat a conventional oven or toaster oven (as well as the Oven, Toaster, and Grill combo device).

In turn, this allows you to do tasks such as reheat cooked food, cook simple food like rice or eggs, bake mug-sized cakes or quiches, and defrost frozen food on short notice in about 5 to 20 minutes depending on your defrosting method.

What’s a Convection Microwave Anyway?

A convection microwave, like the OTG, is a combo appliance. It combines the microwave radiation of the microwave oven that quickly heats food inside-out and a convection oven mode that roasts or bakes food from the outside-in.

The best of both worlds, in short. You can do simple cooking tasks with your microwave mode, do more complicated cooking tasks with the convection oven mode, or quickly cook or reheat food using combo mode (the microwave and convection oven turned on at the same time).

Some convection microwaves can only do microwave mode and convection mode, with no mode that combines both. Others can combine both modes with the caveat that you can’t use tinfoil or metal in combo or microwave mode due to the nature of microwaves.

Which Appliance is Better or Worse?

By default, you’d think that the convection microwave should be better than the microwave due to it combining the convection oven with the microwave into a combo device. However, its prohibitive price might force others to opt getting a separate microwave and oven investment instead.

A convection microwave can reach higher temperatures than the microwave, allowing you to do things the microwave can’t like roasting, toasting, browning, grilling, and baking food.

Easier to Heat Food with

You can use the microwave oven to heat packaged food, defrost frozen food, make crunchy popcorn, and reheat cooked food using microwave radiation (not to be confused with nuclear radiation from Chernobyl).

Meanwhile, a convection microwave oven does all of that yet has a mode that allows it to work as an old-fashioned oven or stove. So you can preheat the oven, heat up food with microwave mode, then cook or roast it completely with convection mode.

In contrast, an “ordinary” microwave oven doesn’t get hot when heating the food.

Easier to Clean

Microwave ovens make cleaning and maintenance easier. Just use a damp cloth or sponge to clean the interior after every microwave session. Wipe the oven from the inside then you’re good to go. Boil a bowl of water mixed with vinegar or lemon juice in order to deodorize the appliance as well.

A convection oven could be cleaned this way too, but with the caveat of requiring more thorough cleaning of heating elements or grill attachments when using convection mode.

Emission Standards

Both microwave types meet emission standards as per national or international requirements. This means they cannot emit more than five milliwatts of radiation per square centimeter beyond 5.08 centimeters or 2 inches from the unit.

This prevents issues like pacemaker damage from people using the microwave from nearby.

Cost or Price

The upfront cost of the OTG or conventional oven is lower. However, the microwave oven offers superior energy efficiency. The standard microwave uses 20% less energy than an oven or OTG, which saves you money in the long run,

A convection microwave, on the other hand, does a balancing act when it comes to its convection and microwave modes to save you power regardless. However, due to the presence of a convection mode, it’s less energy efficient compared to a “standard” microwave.

Interior Capacity

Convection oven sizes tend to be measured by the number of slices of bread you can fit inside if they’re OTG, such as 4-slice, 6-slice, or 9-slice models. The more bread slices you can fit into your toaster oven the more countertop space it occupies.

A microwave tends to have a bigger interior size compared to toasters or OTGs, especially the models that don’t use turntables (flatbed microwaves). A convection microwave can get even bigger than a standard microwave to make way for the convection fans.

As for microwaves and their capacities, those are measured by cubic feet (1 cubic foot or 0.7 cubic foot). You can fit a whole chicken or some other bird with some commercial-sized microwaves!

What You Need to Know

Traveling from the radar rooms of World War II to today’s modern kitchen, the evolution of the microwave oven has been nothing short of amazing. People use microwaves to defrost frozen food, reheat cooked food, and do simple cooking tasks

This includes baking mug cakes, cooking eggs, and heating vegetables. A convection microwave does all those things and more—with “more” referring to its convection oven mode capable of roasting, baking, toasting, cooking, grilling, and so forth.
