Baked Potatoes

Posted on June 4, 2013

The perfect baked potato has crisp golden skin on the outside and is pure white and fluffy on the inside. It's very easy to bake the perfect potato. If you follow the easy guidelines below, you will always have perfect baked potatoes!

Ingredients:

  • Baking Potatoes
  • Olive oil, vegetable oil, or butter
  • Coarse salt or sea salt (optional)

How To Choose Potatoes for Baking: Any potato can be baked, but for the perfect baked potato with the desired flaky texture, it is recommended that mature, baking-type potatoes such as the Russet potatoes be used. Russets are known as a starchy potato, a baking potato, or a mealy potato. The starch gives the potato it's characteristic fluffiness.

Make sure that the skin has a nice even brown tone without a greenish cast. Inspect the potatoes thoroughly to make sure that there aren't any significant bruises, discolored spots, or sprouts.

 

A sprout of any size can be toxic, but you'd have to eat many sprouts to get sick. Do not buy potatoes if they have sprouted or have a green tint to the skin. The same is true for potatoes that turn a greenish hue. A potato in this condition is "light-struck" which causes a build-up of a chemical called Solanine. This is a natural reaction to the potato being exposed to too much light. The green part, if eaten in large quantity, can cause illness.

When baking a large amount of potatoes at one time, choose potatoes with uniform shapes and sizes; they will cook more evenly and get done at the same time.


Directions:

  1. Adjust the rack in your oven to the middle position and preheat oven to desired temperature (see Cooking Temperature Chart below).
  2. Rinse and scrub (I use a stiff-bristled brush) each potato under cold running water, as you will be eating the skins of these perfect potatoes. Don't soak the potatoes (that will make them soggy. Do not use hot water or you'll start cooking the outside and the inside won't catch up). A majority of the vitamins and minerals are found in the skin, so don't throw it away. Dry each potato thoroughly with a clean towel.
  3. Look the cleaned potatoes over and remove any bruises or discolored spots with the tip of your knife.
  4. Pierce each potato deeply with a fork or sharp knife four (4) times on each side at approximately 1-inch intervals. This will allow steam to escape during the baking. If you don't pierce the potatoes, they may explode during baking in your oven. You don't want this to happen as it makes a terrible mess in your oven!
  5. Wrapping the potato in aluminum foil will produce a soft skin (not crispy). Technically this is steaming rather than baking (as the moisture in the potato remains trapped) and the light, flaky texture will be missing. The texture of a steamed potato is entirely different from that of a perfect baked potato. Save yourself the trouble and expense of wrapping potatoes in aluminum foil and serve perfect baked potatoes. My suggestion is to NEVER use aluminum foil when baking potatoes!
  6. For a soft potato skin, rub the outside of the potato with olive oil, vegetable oil, or butter over the skins. I like to roll the potatoes in coarse or sea salt after rolling in the oil and before baking. Place coarse salt onto a small plate. Roll potatoes lightly in the salt. The skin is so yummy to eat!
  7. Bake on racks of oven until tender.
  8. Bake according to the Temperature Chart below. Do not overcook potatoes as the insides will be dry, so it's important to be vigilant.


Cooking Temperatures for Perfect Baked Potatoes Every Time:



Conventional or Regular Oven:
(about 5 ounces or 150 grams each)

45 minutes at 400 degrees F. 
60 minutes at 350 degrees F. 
90 minutes at 325 degrees F.

Place the potato directly on the oven rack in a preheated oven. Place a baking sheet (I put a piece of aluminum foil) on the lower rack (below the potatoes) to catch any drippings

Potatoes are done if tender when pierced with a fork and the internal temperature reaches 210 degrees F. You can also use a meat thermometer to test for doneness.

You can also test for doneness by gently squeezing the middle of the potato (using a pot holder). If it gives in easily to your touch, it is done.

NOTE: If you're cooking more than 4 potatoes, you'll need to extend the cooking time by up to 15 minutes.
 



Convection Oven:
Medium-size potatoes (about 5 ounces or 150 grams each)

45 minutes at 375 degrees F.
60 minutes at 325 degrees F.
90 minutes at 300 degrees F.

Convection ovens cook up to 20% faster than regular ovens. Also, the food in a convection oven is cooked at a lower temperature than in a regular oven to achieve the same results.

The general rule is to decrease your oven temperature at least 25 degrees lower than a regular oven.

You can also use a meat thermometer to test for doneness. Potatoes are done if tender when pierced with a fork and the internal temperature reaches 210 degrees F.

 

This is the type of cooking and meat thermometer that I prefer and use in my cooking. I get many readers asking what cooking/meat thermometer that I prefer and use in my cooking and baking. I, personally, use the Thermapen Thermometer shown in the photo on the right. Originally designed for professional users, the Super-Fast Thermapen Thermometer is used by chefs all over the world. To learn more about this excellent thermometer and to also purchase one (if you desire), just click on the underlined: Thermapen Thermometer
 


The higher the oven temperature, the shorter the cooking time will be and the crustier the skin. Larger potatoes will take longer to bake. Bake potatoes along with whatever else you are baking and gauge the cooking time according to oven temperature.

Turn the potatoes over halfway through the baking time to prevent browning of the undersides where they touch the oven rack.

Potatoes are done if tender when pierced with a fork and the internal temperature reaches 210 degrees F. Use a meat thermometer to test for doneness. You can also test for doneness by gently squeezing the middle of the potato (using a pot holder or oven mitt). If it gives in easily to your touch, it is done.

When baked to perfection, remove potatoes from the oven. Slit across the top with a sharp knife. Gently pinch (squeeze) in each end of the potato towards the middle (using your thumb and index finger). The potato will pop oven loosen the fluffy white interior from the skin. Be careful as there will be some steam.
