Why are high temperatures the best for cooking a baked potato?

Baked potatoes are quite easy to cook and don’t need a lot of temperature change, just one temperature that they bake on for the total time will suffice.

Although, that temperature needs to be very high so that the potato bakes perfectly and ideally till the middle and does not leave any parts of the potato uncooked. 

It’s ideal to cook your baked potato at a temperature between 300°-425°. Make sure to not go above 425° as that will overcook, dry up, and burn the potato, in which case it will not make for an appetizing dish. 

The ideal temperature for your baked potatoes is 400° as it’s not too high (425° and above) as to overcook the potatoes and not too low (375° and below) to undercook them.

Make sure that your oven is pre-heated so that your potato is fully cooked and the skin is perfectly crunchy.

How to cook the perfect baked potato?

The recipe for cooking the perfect baked potato requires a few simple steps, follow it to a T and the outcome would be a baked potato perfectly crispy on the outside and fluffy on the inside.

Here’s what you need to do:

1.    Pick a potato

Many people are confused as to which type or kind of potato they should choose for making baked potatoes.

The answer to that is choosing a mature, baking-type potato like Russets potatoes, which will give you that perfect potato dish with a smooth interior and a flaky exterior. 

Russets are classically known as baking potatoes and contain a lot of starch which is perfect for baking since it retains the fluffiness of the inside of your potato, keeping it from becoming too dry.

Along with that, you should make sure that your potato has a rust or brown skin color, and not green. This indicates that the potato is perfectly ripe and suitable for baking. 

Avoid potatoes with sprouts as they can sometimes be poisonous to the person eating them. Look for any signs of bruises on the potatoes which indicate rotting from the inside and avoid buying those.

Don’t choose potatoes which are too large or too small, and if you’re baking a lot of them at once, try to get the ones with similar sizes. 

2.    Prepare your potato

After you’re done picking, wash the potatoes in cold water, and rinse them about 3 times to get rid of any dirt, bacteria, or fertilizers that may be hiding on the potato skin.

This will prevent you from getting sick after eating and prevent a bacteria outbreak. 

After they’re done getting cleaned, leave the potatoes out to dry, or pat them dry using a kitchen roll or paper. This will make sure the skin is perfectly dry to go in the oven and turns out crispy instead of wrinkly and moist. 

When they’re fully dry, take a fork or knife, and make several tiny little holes in the surface of your potato.

This prevents the skin from bursting when baking in the oven and allows for the steam to get out easier, creating air pockets for it to escape from.

This also helps cook your baked potato faster and makes it fluffier in texture.

3.    Coat the potato

Now put your potato back into a bowl and put in some olive oil/vegetable oil, salt and pepper. Salt and pepper are optional to give the potato a slight hint of more flavor for you to add condiments onto later.

The oil is necessary as it prevents the potato from sticking to the dish but make sure to rub in the oil into the potato skin so that it becomes perfectly crispy while baking. 

4.    Put it into the oven

Take your baking dish or tray, and line it with baking paper. Before putting your potato into the oven to bake, pre-heat the oven to 400° and adjust the rack in your oven to the middle position.

You can wrap your potato in aluminum foil if you prefer your potato to have softer skin, otherwise, just put it on the tray as is. 

Make sure to use heat protectant gloves to protect your hands and put the tray/dish into the oven. Make sure to put it in after the oven has been pre-heated for at least 15 minutes.

Bake the potato on the racks until it becomes tender.

When half of the baking time has passed, check and monitor the potato accordingly. It’s also advised to take the tray out and turn the potato over using tongs so that it cooks well from all sides, and also to prevent the browning of the potato skin where it meets the baking tray. 

To check if your potato is done, take it out 2-5 minutes prior to finishing time and pierce it with a knife to check.

The amount of pressure you have to force the knife in will tell you if the inside is soft or still hard, in the latter case you’ll have to put it back into the oven for 5 minutes more. 

You can also use a meat thermometer to check the temperature of the middle of your potato; if the internal temperature is 210°, that means the potato has been cooked and you can take it out.

If not, then chuck it back in for a few minutes more.

5.    Serve with toppings and side dishes

Take the potato out when it’s done and make a crisscross cut on the top with a knife.

This 1-inch cut will help the steam get out and make room for any toppings you might want to add, like sour cream, cheese, vegetables, curry, herbs, or anything else. 

After preparing the toppings, take out a nice serving dish (if you’re making it for the guests) and lay your potatoes in it.

You can also choose an appropriate side dish to go along with it although the baked potatoes are a hearty snack all on their own. 

Does the temperature differ when cooking a baked potato using other methods?

The recipe and the optimal temperature of 400 mentioned above was specifically for cooking baked potatoes in an electric oven, so if you’re using any other forms of baking per se, coating your potato with aluminum or tin foil, or using an air fryer, the procedure will be a little different. 

How to bake potatoes in aluminum foil?

Potatoes wrapped in aluminum foil take longer to bake since they now have an extra layer of coverage which the heat has to penetrate for cooking.

You can use the same temperature of 400 for this method as well, however, the potato will have to cook for a longer time per se an hour instead of the regular 45 minutes to cook better. 

How to bake potatoes in air fryer?

Baking potatoes in the air fryer basket takes around 30-45 minutes or less. It’s ideal to bake them for 30 minutes in the air fryer at a temperature of 400 to achieve the desired texture of your potato.

All the other steps such as cleaning, washing, drying, and coating with oil, salt, and pepper are the same as when cooking in an oven. 

Tips and tricks to help you cook baked potatoes better

  • Don’t cover with foil if you want crispy potatoes.
  • Adjust temperature and cooking time according to the size of the potatoes.
  • Use a thermometer 2 times between cooking to check the temperature as eating undercooked potatoes can cause indigestion.
  • Don’t cut all the way down the middle when serving, only by one inch.
  • Squeeze the ends of the potato towards the center to make it fluffier.
