How to Choose a Premium Convection Toaster Oven

FAQ
Is a convection toaster oven better than a regular toaster oven?
Yes for baking and roasting – the fan cooks faster and more evenly.
Can a countertop convection oven replace my oven?
For most everyday meals, a large model can; big holiday roasts may still need a full oven.
Which Breville convection oven should I buy?
Choose the Smart Oven Air Fryer Pro for air frying and size, or the Smart Oven Pro for baking.
Do convection ovens dry out food?
Not if you adjust time and temperature – many recipes reduce heat by about 25°F.
