To get the skin crisp in a hot oiled pan add your chicken and fry the skin breifly. Set to one side and grap your potatoes, wash and slice thinly/quarterly how ever you like it, sprinkle salt, black pepper and add mixed veg into baking tray then add your chicken from the pan on top.
This is how it should look. Pop into oven at 200 degrees for 45-60 minutes. Once this time is up turn the oven off and leave to sit in the oven for 20 minutes then cook for another 45 minutes until it’s crispy and well cooked.
