A burner left on does not announce itself. It shows up as a scorched pan, a smell that hangs around after dinner, or a smoke alarm that goes off for no reason you can see. The problem is not the meal. It is the gap between starting the stove and remembering that it is still on.

Look for the signs in the kitchen
Ask for a look at the stove and the counter, and ask the helper to note what they see before anyone tidies up. Signs to watch for include knobs turned to a setting nobody would use for the meal, a pan dry or burned on the bottom, a towel or paper near a burner, a lid left on a lit ring, a smell of burnt food in rooms far from the kitchen, and a smoke alarm that goes off during or after cooking.
Separate one mistake from a pattern
A single scorched pot is a mistake. Repeated signs are a pattern. Watch for the same burner left on more than once, a meal started and never finished, a parent who leaves the kitchen during cooking and does not come back for a long time, or a pan found cooked dry after the meal is over. The pattern is what matters, and it is the reason a phone check-in will not catch it. A visit will.
Set the stops that fit the kitchen
Knob covers that show whether a burner is on, and appliances with an automatic shutoff, are common ways to add a step without taking the stove away. Ask your parent before buying anything, because a device they resent will not get used. Cooking on the stove less often for everyday meals is another option, and it is your parent's choice in the end.
Check that the smoke alarm works and sits where it can hear the kitchen. Public fire safety guidance from the U.S. Fire Administration covers cooking fires and alarms, and the Sources page lists where to find it.
Who can help in the kitchen
A non-medical caregiver can be present at mealtimes or help with cooking as a household task. That puts a second set of eyes on the stove. Keep the arrangement simple and written down, so the helper knows what to watch for and whom to call. The helper's job stays in the kitchen.
What to do tonight
Ask your parent to show you the stove on video. Have them name which knob controls which burner, and ask them to turn each knob off while you watch. Ask a local contact to look at the kitchen before the next meal and tell you what they see. Make a short list of the last few times anything scorched.
What to leave with the doctor
Describe the pattern with specifics: which burner, what happened, how often, and what your parent said about it. Ask whether anything medical could be behind the pattern, and whether a memory or attention check makes sense. Ask what the doctor would want to see before the next appointment, and whether a plan for cooking belongs in the chart. Bring the notes from the kitchen visit.
