I can't remember where I saw this idea, but we've been baking potatoes like this forever.
Easy Restaurant Style Baked Potatoes
Ingredients: Baking Potatoes Olive Oil Sea Salt
(Regular salt is fine too - I only have Sea Salt because my Mom gave it to me!)
Wash potatoes, prick lightly 2 or 3 times and cook them in the microwave for about 1/2 the time you normally would. I cooked 3 fairly large ones for 10 minutes in the microwave. You want to be able to feel a little give in the potato but not so much you can break the skin.
Remove from the microwave - CAUTION - They will be HOT! Then brush them will Olive Oil and sprinkle with salt. Bake in the oven at 375 degrees for 20-25 minutes - not necessary to wrap them in tin foil - although I usually cook them on a piece of foil for easy clean up. That's it!
They come out light and fluffy and the best part about potatoes baked this way is the skin - YUMMY!
