Some say wrapping baked potatoes in aluminum foil helps them cook faster (aluminum conducts heat, then traps it), and it does keep them hot for longer once they come out of the oven, which is why we think restaurants use this method. Wrapping potatoes will also give you a softer, steamed skin, if that's what you like.
NEVER BAKE POTATOES IN FOIL.
Foil wraps will not decrease baking time, but will result in a soggy potato interior with wet skin. Wrapping a baked potato in foil after it has been baked will allow you to hold up to 45 minutes, but the best method for holding a baked potato is in a bread warming drawer.
Foil will prevent potatoes from drying out while they are kept warm – one of the reasons restaurants serve their baked potatoes in foil.
They trap moisture and flavor, making cooking faster and more efficient. Plus, the versatility of different recipes and ingredients used in foil packet dinners makes them suitable for various tastes and dietary preferences.
Wrapping a potato in foil prior to baking traps the potato's natural moisture, steaming instead of baking it. This results is a soggy baked potato, not the light fluffy Idaho Baker that most people prefer.
If you're baking fish, roasting vegetables or preparing a piece of meat for dinner tonight, chances are that you'll wrap your food in aluminium foil. What you may not realise is that some of the foil will leach into your meal – and this could be bad for your health.
This creates tiny holes that allow steam to escape so your potato doesn't burst open in the oven (and make a mess!). Is it better to bake a potato at 350 or 400 degrees? To get a nice, fluffy interior and the crispiest skin, bake your potatoes at 400 degrees.

Answer. Chefs started doing this years ago to allow the salt to absorb or draw out the moisture of the potato while baking, which results in a dry, fluffy potato. They used to do something similar with prime rib, sometimes baking it over rock salt.
Don't forget to poke holes in the potato: Use a fork and poke the potato four or five times on each side. These little holes allow steam to escape while the potato is cooking. Forget to poke, and your potato could end up exploding in your microwave from the pent-up steam. It's both messy and a serious dinner let-down.
Russet potatoes are arguably the best potatoes for baking, although they are also great for mashing and frying. The main reason thick-skinned Russet potatoes are perfect for baking and more is because they contain significant amounts of starch.
Baked potatoes offer more nutritional value than fries because they still have skin. Potato skins are the most nutrient-dense part of a baked potato. Another benefit of heart-healthy baked potatoes is that they are not deep-fried in oil and grease like french fries.
Much less dramatically, hole-poking gives you superior baked potatoes. According to the Idaho Potato Commission, potatoes are about 80 percent water. As your potatoes bake, some of that water converts to steam and exits through the tiny channels you poked in them. This moisture loss is a good thing.
Visual signs: The potato skin will start to wrinkle when over cooked. The potato, when wrapped in foil or placed on the bottom of a pan will have a dark brown spot on the bottom, a sure sign of over cooking. Foil traps the moisture in the potato causing the skin to be wet and the inside flavorless or gummy.
We recommend 400° F. In previous studies with Kitchen Consultants, out of Los Angeles, we raised our baking time suggestions from 45 or 55 minutes to one full hour or when the internal temperature of the Idaho® baked potato reaches 210° F. Baking in foil is NOT recommended, as it steams the potato.
Safely Bake A Potato In Foil
Potatoes wrapped in foil don't have much oxygen, creating an ideal environment for botulism. "Botulism is caused by a bacteria called Clostridium Botulinum that is found naturally in the environment, particularly in the soil," says Baker.
"I see a lot of people using foil to wrap their potatoes in but this is a big no-no and causes soggy skins!" he says. Foil holds in moisture and steams the potatoes, resulting in a "boiled" taste and texture. Plus, without the use of foil, the skin will get extra crispy and flavorful.
Cook at 425 to 450 F for almost an hour
In order to achieve restaurant potato perfection, cooking your spuds in the oven is still the number one option.
Expert Tips. Cover Potatoes: If you want to keep moisture in your potatoes, bake them covered with foil for the first 30 minutes and then take the foil off just for the last 5-10 minutes to really crisp up.
It takes about 1 hour to bake a potato in the oven at 400 degrees. Scrub the potatoes clean, poke holes with a fork, and rub with oil, salt, and pepper if desired. Bake directly on an oven rack for 60 minutes.
Baking a potato can take an hour, while microwaving takes about 10 minutes. An equally good reason is this method produces a superior baked potato. A long time in the oven can often dry out the interior of a potato, but not so with the microwave. It steams the interior of the potato, keeping it moist and fluffy.
Small amounts of aluminum can also enter your bloodstream but will leave your body quickly through the urine. Research shows that cooking aluminum at high temperatures and the use of acidic foods, salt and spices did perpetuate a greater amount of leaching of the mineral.
The problem? Foil does not completely seal the food from air, which allows bacteria to grow faster. Some bacteria, like staph, can make toxins which are not killed when food is cooked. Bacteria can grow on the food and cause foodborne illnesses.
It's important to avoid using aluminum foil with acidic foods like tomato-or vinegar-based dishes, citrus fruits, or marinades containing citrus juices. Acidic ingredients can corrode the foil, causing aluminum to leach into the food, which may result in a metallic taste.
