how long do you microwave a potato before baking
1 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.. Put the plate in the microwave and choose a cooking time. Cooking times will vary depending on the size of the potato and the power of the microwave. Most medium to large potatoes will take between 8-12 minutes to cook at full power.
