The oven that comes with your stove is huge and it takes forever to preheat. I remember mine used to take like 20 minutes to preheat. For a lot of things that doubles the cooking time.
A toaster oven has way less space to heat, together with the fast convection makes it heat up almost instantly and also evenly. It’s just such a huge quality of life improvement.
I wish we had space for either one. Assuming an air fryer can grill cheese as well as a toaster oven, I’d be fine with just the latter though. I miss my toaster oven.
If you have the money, I’d definitely recommend a toaster oven with “air fryer” capabilities (air fryers are just convection ovens… with more convection). However they are more expensive than just an air fryer. Air fryers are also smaller so that can be a big pro if you are limited on space.
Grill cheese in an oven? Gotta use a stovetop for that.
Or a grill. Ya know, 'cause it’s grilled cheese.
Technically, it’s a Welsh Rarebit, but most people in the U.S. don’t know what that is, so I call it grilled cheese.
