Preferably something that has little to no preparation required.
Do ovens not have timers where you live? That’s wild.
In my country, you set the timer (and temperature obv) on your oven for how long whatever you have needs to cook, and once it’s counted down to 0, the oven switches off.
So you can put sweet potatoes in the oven to cook for an hour and go to bed- and get this right, in the morning you wake up to perfectly cooked and still slightly warm sweet potatoes, and a house that isn’t burnt down.
Crazy or what right? So futuristic and high tech.
My shit just beeps at the end of the timer and you can’t even hear it if you’re in the other room. If you forget to turn off the oven, it just stays on forever.
…piece of shit
If it’s not wired into the wall, you could plug it into a timer and set it that way.
I didn’t even know this was possible. Looks like my current oven may be able to do it - it has a ticking timer knob - but pretty sure all previous ones didn’t have this feature.
Other than the use case you have mentioned I can’t see any reason to use it. It would be annoying to have the oven turn off before the food is cooked to perfection, which it rarely is at a prescribed time
