How Long Should You Bake Potatoes At 375° In Foil?

Baking potatoes at 375° F in foil depends on what cooking equipment you’re using and the size of the potatoes. But generally, the cooking time is about 20-25 minutes.

If you’re using large potatoes and want them to have crispy potato skins, you can bake potatoes at 375° F for about 30 minutes.

Using an air fryer, you should wrap potatoes in foil, and air fry them at 375° F for about 50-65 minutes and up to 70-80 minutes if frozen potatoes.

For the oven, bake potatoes in foil at 375°, which should last for about 60-70 minutes. Still, the timing depends on the size of the potatoes.

But how can you cook frozen twice-baked potatoes?

Factors to Consider 

Size of Potatoes


Baking baby potatoes in foil takes a shorter time than the bigger ones because the heat can penetrate the little waxy potatoes and cook the insides. Generally, smaller sizes cook faster.

Don’t forget to shake the baking sheet often so the baby potatoes won’t burn. Small potatoes in aluminum foil take about 15 to 20 minutes of baking in an air fryer or oven at 375° F.



Medium potatoes can be easily cooked in an air fryer or oven at 375° in foil or a baking sheet. But make sure you have a preheated oven before placing the potatoes.

Medium-sized potatoes in foil cook better because you don’t have to adjust too much and too little of the standard baking time according to their size.


When baking potatoes, especially large starchy potatoes, you need to preheat the oven or an air fryer because using foil might take too long to bake potatoes.

If you’re cooking it at 375°, it is recommended to cook them for at least 30 minutes to prevent undercooked potatoes.

If you’re using the oven to bake potatoes in foil, you should preheat it before placing your foil-wrapped potatoes. Take note of the size of your oven if it can cook large Russet potatoes. 

Ensure that the insides of your oven are clean to avoid any unexpected changes in the flavor. After 30 minutes, get a fork and poke each baked potato to check if they’re cooked.

Oven-baked potatoes are one of the best sides for grilled chicken. If you’re making it at home, the oven is the equipment. 

Air Fryer

It is easier to cook potatoes in an air fryer than in an oven because it provides equal heat distribution. You can also use air fryers in baking sweet potatoes and red potatoes to achieve crispy skin.

Wrapped potatoes in foil are quicker because you don’t need to flip them every 20 minutes. But because the heated pan is at the bottom, you must follow some precautions.

Larger potatoes might cook poorly in an air fryer too. So you have to take note of the sizes. But is it alright to use aluminum foil in an Emeril Lagasse air fryer?

Does It Take Longer To Bake in Foil? 

Yes, using foil can slow the process of cooking potatoes, especially if you cover each potato entirely. It is because the foil needs to heat before the potatoes start to bake.

The heat from the oven or air fryer will take time to penetrate the potato, thus increasing the baking time. Also, the foil locks in the moisture inside, preventing the potatoes from being crispy.

To hasten the baking time, boil potatoes before wrapping them in foil. Brush olive oil or unsalted butter around the potato to get perfect baked potatoes.

How To Tell If Baked Potato In Foil Is Cooked?

To tell if the baked potato in foil is cooked, poke the middle of the potato with a fork. It is already done if the fork pierced easily into the potato’s skin. But if it is still hard, reheat the baked potatoes.

It is hard to know whether a baked potato in foil is already cooked. The best way to cook it thoroughly is to follow the cooking time based on the potato sizes.

Should You Wrap It In Foil? 

Yes, baked potatoes should be wrapped in foil to cook evenly if you prefer them to be mushy rather than crispy.

But if you want to bake potatoes at 375° and get crispy-skinned baked potatoes and mushy inside, you should not use foil.

Potatoes cook evenly in a foil, allowing the hot air to penetrate potatoes to the core. 

When baking potatoes at 375° in foil using an air fryer or oven, it prevents the outer layer of the potato from burning. [1] 

Wrapping the potatoes tightly with aluminum foil could also prevent the whole baking process from being messy because the olive oil and condiments are covered inside.


Should you poke holes in baked potatoes?

Yes, you should poke holes in potatoes to let the hot air penetrate inside and to know if it’s already cooked or not.

Poking holes in potatoes is the common way to know if it is ready for serving or not. [2] 

What are the benefits of baking potatoes in foil?

The benefit of baking potatoes in aluminum foil is to cook potatoes evenly to the core. 

It prevents uncooked baked potatoes because foil traps heat and moisture and lets it circulate the potato. Using foil could also lock the flavor of the food.

In Conclusion

We conclude that the baking time of potatoes at 375° in foil primarily depends on the size of the potatoes. But you have to take note that using foil and baking sheets may require a longer baking time for the potatoes.

If you want to bake a potato and want to achieve the potato’s crispy skin, choose Idaho potatoes. Best baked potatoes in foil, like Russet potatoes, are grown in Idaho.

If you prefer a crispy potato skin or soft mashed potatoes, follow the cooking time, and you’ll get perfectly cooked potatoes for your potato salad with sour cream or your favorite toppings.
