Well then this employee must've done it wrong, because I cook bacon in my toaster over (and now an air fryer) all the time.

However, you do need a tray on which the bacon sits, which was perhaps your employee's mistake.

Are people using the word toaster to refer to two different appliances in this thread? In American English a toaster is a device that holds bread vertically between heating elements. There's a similarly named device called a toaster oven which is essentially a standard electric oven that's been shrunk down to countertop size.

Both the parent and grandparent to your comment were referring to a toaster oven.

Hey now, I envision a device which slides into a vertical toaster slot, and toasts bacon, whist catching the grease.

Anyone want to coin in?

Well that sounds like a jolly good idea! What, you suggest a kickstarter?

Go for it!
