Convection Microwave vs OTG Oven: Which Should You Buy?

Both appliances can bake, but they are built for different kitchens. A convection microwave does more jobs in less space. An OTG (oven toaster griller) bakes more like a traditional oven. Here is how to pick.

How they differ

Reheating and defrostingYes, microwave modeSlow, no microwave mode
BakingYes, with convection modeYes, often more even on large trays
GrillingYes (with grill mode)Yes

Choose a convection microwave if

  • You want one appliance for reheating, baking and grilling
  • Counter space is limited
  • You mostly cook small to medium portions

Choose an OTG if

  • You bake often, especially cakes and breads in large trays
  • You already own a microwave
  • You want lower upfront cost

Capacity guide

  • 20 to 25 L: couples and small families
  • 25 to 30 L: families who bake
  • 35 L and above (OTG): large trays and multiple racks

Tips

  • Use only the cookware the manual allows in each mode.
  • Preheat before baking for better results.
  • Check that a rack and a turntable are included.

For crisp, fast cooking of small batches consider an air fryer. See air fryer vs oven and our top picks.
