how long to grill a baked potato in my microwave/grill oven?
1 For example, if one large potato takes 10 minutes to cook, two large potatoes would take between 16-17 minutes.  If you prefer crispy skinned potatoes, you can cook the potatoes in the microwave for 5-6 minutes, then transfer to a baking sheet and bake in an oven preheated to 400 Â°F (204 Â°C) for 20 minutes. This method is great if you want oven-crisp potato skins, in less than half the normal cooking time!
