Baked potatoes wrapped in foil and cooked in the oven are a classic easy dinner side dish. But how long does it actually take to cook a baked potato in the oven when it’s wrapped in foil? There are a lot of factors that determine baking time for potatoes, so it’s not quite as straightforward as you may think.
This article will provide a thorough overview of how long it takes to bake potatoes wrapped in foil in the oven. We’ll cover how cooking times are affected by potato size, oven temperature, elevation, and more. You’ll also find helpful timetables and charts as well as answers to frequently asked questions about cooking foil-wrapped baked potatoes.
Factors That Affect Baked Potato Cooking Times
Many different factors impact how long it takes to cook a baked potato wrapped in foil in the oven. Here are some of the key considerations:
Potato Size
Larger potatoes take longer to bake than smaller ones. A good rule of thumb is approximately 5 minutes per ounce of potato.
- Small potatoes (4-6 oz): 30-45 minutes
- Medium potatoes (8-10 oz): 45-60 minutes
- Large potatoes (12-16 oz): 60-80 minutes
- Extra large potatoes (over 1 lb): at least 90 minutes
So if you have a 10 ounce potato, expect it to take around 50 minutes to bake if using average cooking temperatures (see below).
Oven Temperature
Higher oven temperatures will significantly decrease baking times for foil wrapped potatoes. Lower oven temperatures will increase bake times.
- 350°F: Takes roughly 35-60 minutes depending on size
- 375°F: Takes roughly 30-50 minutes depending on size
- 400°F: Takes roughly 25-45 minutes depending on size
- 425°F: Takes roughly 20-40 minutes depending on size
If you want your potato done faster, crank up the oven temp. Just watch closely for burning at higher temperatures.
Elevation
Higher elevations will increase the time it takes a potato to bake since water boils at lower temperatures at higher elevations. For every 1,000 feet above sea level, add 5-10 minutes to the baking time.
Potato Type
Waxy potatoes like red potatoes or new potatoes generally cook faster than starchy russet potatoes. They have less starch and moisture. Expect waxy varieties to cook 5-10 minutes faster than russets.
Oil or Butter
Rubbing potato skins with oil or butter before wrapping in foil helps conduct heat for faster, more even cooking. This can shave off 5-10 minutes of baking time.
Pricking Potato Skin
Some bakers recommend pricking the potato skin with a fork a few times before baking to allow steam to escape and reduce baking time. This can help speed things up slightly, but be careful not to prick too deeply into the flesh.
Microwaving First
Microwaving the potato first for 3-5 minutes before putting it in the oven wrapped in foil can reduce the total baking time. This helps partially cook the inside before the oven crisps and browns the skin.
Baking Time Charts for Foil Wrapped Potatoes
Here are some general timetables for how long to bake foil wrapped potatoes of different sizes based on average conditions (350°F oven at sea level). Adjust times as needed based on the factors above.
At 350°F
- Small potato (4-6 oz): 45-60 minutes
- Medium potato (8-10 oz): 60-75 minutes

Wrapping potatoes in foil before baking is a simple trick that leads to tender, fluffy results every time. The foil tenting seals in steam to cook the potato interiors while still allowing the skins to get crispy. Baking times can range quite a bit based on the size of the potatoes and factors like oven temperature. But in general, medium russet potatoes take around 1 hour to bake at 400°F when wrapped in foil. Adjust bake times up or down by following the recommendations in this article.
The most reliable doneness test is simply poking the potatoes with a fork to check if the centers are soft all the way through. Let foil-wrapped potatoes rest for 5-10 minutes after baking before unwrapping and adding your favorite toppings. Following the tips in this article will ensure you achieve baked potato perfection.
Frequently Asked Questions
Here are some frequently asked question given below:
Should the foil be sealed or open when baking potatoes?
There’s no need to tightly seal foil over the potato. Wrapping loosely in foil tents the spud and helps retain moisture as it bakes. Leaving openings at the ends or loosely sealing the seam allows steam to vent.
Does poking holes in the potato speed up baking time?
Poking a few holes through the skin with a fork can allow steam to escape from the interior and reduce baking time slightly, by around 5-10 minutes. But take care not to poke too deeply into the flesh which can cause the potato to cook unevenly.
What temperature is best for baking potatoes fast?
Higher oven temperatures will significantly speed up baking times. A 425°F oven will bake potatoes nearly twice as fast as a 350°F oven. But watch closely for burning at higher temps. A good middle ground is around 400°F.
Should you microwave before baking potatoes in the oven?
Yes, microwaving potatoes first for 3-5 minutes before baking in the oven can shave off quite a bit of time from the total baking duration, around 10-15 minutes. Microwaving partially pre-cooks the interior before the oven crisps the skin.
How long does it take to bake small potatoes?
In a 375°F oven, small 4-6 ounce potatoes take approximately 30-45 minutes when wrapped in foil. Increase time to 35-50 minutes at 350°F or reduce time to 25-35 minutes at 400°F. Adjust cooking time based on specific potato size and oven temp.
What is the best way to tell when baked potatoes are done?
The most reliable test for doneness is simply poking the middle of the potato with a knife or fork. The center should feel completely soft when it’s fully cooked through. If it still feels firm, continue baking. The skin will also crack open slightly when it’s finished baking.
Should you wrap in foil first or poke holes first before baking potatoes?
It’s best to wrap the potatoes in foil first before poking any holes through the skin. This allows steam to vent through the holes rather than excessive moisture escaping the unwrapped potatoes.
How long does it take to reheat a baked potato?
To reheat a previously baked potato, wrap it back in foil and place it a 300°F oven for 15-20 minutes until warmed through. You can also reheat in the microwave for a couple minutes by poking holes in the potato to vent steam. Take care not to overcook the microwaved potato.
