How to Bake a Potato in the Microwave
Try putting the potato in for 5 minutes to begin with, then take it out and turn it over so that both sides cook evenly. Place it back in the microwave for another 35 minutes, depending on how soft it is already. After that, if it still doesnt feel fully cooked, continue to microwave it in 1 minute bursts, checking after each minute.3
If you are cooking multiple potatoes at once, you will need to increase the cooking time by about twothirds. For example, if one large potato takes 10 minutes to cook, two large potatoes would take between 1617 minutes.
If you prefer crispy skinned potatoes, you can cook the potatoes in the microwave for 56 minutes, then transfer to a baking sheet and bake in an oven preheated to 400 degrees F for 20 minutes. This method is great if you want ovencrisp potato skins, in less than half the normal cooking time!3
Some microwaves have a baked potato button; use that when in doubt.
Lengthen the time when using microwaves with less power. An 800 Watt microwave requires 1.5 times the microwaving time.
Using a rotating carousel for microwaving is the best way to get the potato evenly cooked all around. If you dont have a rotating carousel, pause your microwave twice during the microwaving time, and manually turn the potato a half turn each time. To decide when to turn the potato, divide the cooking time into 3 fairly equal units.
If you are in a rush, you can cut open the potato immediately after the microwave stops, add your toppings or not, and then do the final cooking in the microwave by microwaving another 30 to 60 seconds.
You can boil potatoes for mashing more or less the same way. Use thinskinned potatoes and be extra careful not to dry them out. Plastic wrap or simply cooking several in a plastic bag helps.
