Do you have a way of making sure you did not leave the stove on?

Well, I have a smooth-top electric stove and I also have cats that like to hop up on my counters when they think I’m not looking. I keep two (attractive) tea kettles on my stove at all time, and I have gotten into the habit of putting the kettles over a hot burner so that my cats don’t accidentally burn their paws.
If it starts whistling a little bit later, I know that I forgot to turn off the burner.

I recommend not cooking anything.I love this method :)

Since this is maybe just a temporary situation for you, how about a timer with a really annoying ring to it?

I agree with @mazingerz88 that you should get one of those cute little egg timers and use it every time you turn on the stove. Then, for a second defense, put a little post it note where you are going to be next (bathroom, front door, door to the garage, your car dashboard) Put the post its and pen next to the stove and USE them each time.

I just always immediately turn off the stove as soon as I’m done with it…sorry, boring answer, lol!

Use the old string around the finger trick. Whenever you turn the stove on tie a string around your finger, you’ll eventually look at your hands and wonder what is this string doing here….Oh! I turned the stove on.

I just turn it off after I’m done, I don’t know why exactly….but I know it’s not supposed to be on overnight lol.

Not with reference to stoves specifically, but with exceptional forgetfulness generally: to me it is a cue to look deeper, urgently. Something is going on, some kind of stress or distress that is showing up as absent-mindedness. If I lock myself out of my car twice in one week, or leave my glasses somewhere, or (as I have done more than once) go to work leaving my company-issued work laptop at home, it’s a sign of trouble that I may not be acknowledging. If I deal with the disturbance, the symptom goes away.

I do have some habitual lapses, though, that I’ve had to treat with a rigid rule. For instance, I do not shut the car door unless my key is in my hand. Not in my purse or in my pocket where I can’t see it (and may mistakenly assume it is safely stowed), but actively and visibly present in my hand. Same with house key.

When it comes to the stove, like others I simply turn it off the moment I’m through using it.

I turn it off soon as I’m done, but I alsoo double-check by looking at the lights on the panel. 1 light=good, the top is just still hot but off, 2 on=I need to turrn somethingg off.

“Did I turn off the stove?” – Stop the car, turn around, go home, unlock door, check.

I like @hug_of_war ‘s advice. If the little indicator lights are burning that means the stove is on.
