Charlie loves cooking so much that I started thinking about when we can put him in charge of dinner. So I did some Googling, and I came across this link that says your child should be at least 11 before they have responsibility for cooking:

Hmm, 6th grade... that sounds pretty reasonable to me. He's definitely going to be making a lot of food in the kitchen well before then though! We definitely want to encourage his love of the kitchen, since I think he eats better when he's made his own food... and he's not a great eater.

How old will your LOs be before you let them use the stove?
