The right baking temperature is a key component to mastering such a potato, but it's the internal temperature that you should really be paying attention to.
The general internal temperature you should aim for is between 205 and 212 degrees Fahrenheit, which ensures the potato will be light, airy, and fully cooked.
Therefore, the best oven temperature depends largely on the variety and size of the potato. Recipes can call for an oven to be preheated anywhere from 250 to 450 degrees F.
Just don't crank up the heat too high for the sake of speed — your potato may just burn up. Always keep an eye on the internal temp and look out for telltale signs of overcooking.
Invest in a probe thermometer to best ensure that your potatoes have reached the appropriate internal temperature, which makes for fluffy and moist results.
