How long to bake a potato at 425? A medium russet goes in the oven for 45 to 60 minutes and comes out with a crisp skin and a fluffy center. That range is wide because size matters more than the clock, so the trick is learning to test for tenderness instead of trusting the timer alone.
425°F (220°C) sits in the sweet spot for baked potatoes: hot enough to dry out and crisp the skin in about half an hour, gentle enough that the inside cooks through before the outside burns. It’s the temperature I bake at most weeks, and it’s the one I’ll walk you through here. This is still the method I come back to in 2026, with the times below and the doneness checks that never lie.

How Long to Bake a Potato at 425°F?
Bake a potato at 425°F for 45 to 60 minutes, depending on size. A 6-ounce potato is closer to 45 minutes. Anything over a pound needs a full hour or a little more.
Here is how long to bake a potato at 425 by size, with the visual cue to trust instead of the timer.
| Potato size | Approximate weight | Time at 425°F | What done looks like |
|---|---|---|---|
| Small | 5 to 6 oz | 40 to 45 minutes | Skin crisp and dark golden, fork slides in with no resistance |
| Medium | 7 to 8 oz | 45 to 55 minutes | Skin wrinkled and dry, flesh steamy and pale yellow |
| Large | 10 to 12 oz | 55 to 65 minutes | Skin dark and papery, center yields to a fork |
| Extra large | 1 lb plus | 65 to 80 minutes | Skin very dark; check at 65 minutes and keep going |
Four things move the clock. Foil slows the skin down by roughly 10 minutes because the potato steams in its own jacket. Starting from cold after the fridge adds 10 to 15 minutes. Potatoes touching each other cook unevenly, so give them space. And a home oven that runs 25 degrees cool turns a 45-minute bake into a 60-minute one, which is why an oven thermometer is the cheapest fix in the kitchen.
For comparison, here is how the same medium potato behaves at other temperatures.
| Oven temperature | Time for a medium potato | Trade-off |
|---|---|---|
| 400°F (205°C) | 50 to 60 minutes | Softer skin, very forgiving |
| 425°F (220°C) | 45 to 60 minutes | Crisp skin and even cooking, best all-around |
| 450°F (230°C) | 40 to 50 minutes | Crispiest skin, narrowest window before the outside burns |
Is 425 too hot for potatoes? No. It is hot enough to set a crust but not so hot that the skin burns before a large potato finishes inside. Anything above about 450°F narrows that gap and makes timing much less forgiving.
How to Bake a Potato at 425°F
This is the bare method I use about nine times out of ten: no foil, wire rack, oil, coarse salt.
- Heat the oven to 425°F (220°C) and let it run a full 10 to 15 minutes before the potatoes go in. Put a wire rack inside a rimmed baking sheet and heat that too, so the potatoes never sit on a cold pan.
- Scrub the potatoes under cool water and dry them well. A damp skin steams instead of crisping, and that one habit is the biggest difference between a good baked potato and a disappointing one.
- Give each potato 6 to 8 fork holes. Poke straight in from the top and a few times from the side. Steam needs a path to escape, and without holes a large potato can burst in the oven.
- Rub the skins with oil and coat them well. Olive oil, avocado oil, or duck fat all work. The oil is what turns the skin from leathery to crisp.
- Add a generous layer of coarse salt all over the skin. Salty skins get compliments more than any other detail here, and the salt forms a crust that crisps as the moisture leaves.
- Set them on the rack, not touching, with an inch of space between each one.
- Bake for 45 to 60 minutes, starting at 425°F. At the halfway mark, turn each potato with tongs so both sides crisp evenly. Turning is optional but it is the fastest fix for one pale side.
- Test for tenderness, then split, fluff the inside with a fork, and top it.
Let the potato sit for two or three minutes after it leaves the oven. The interior finishes setting as the heat spreads outward, and fluffing too early can turn the center gummy.
Do You Need to Peel Potatoes Before Baking?
No, and you should not. Almost all of the flavor and a good chunk of the potassium live in the skin, and the skin is what turns crisp in the oven. Peeling before baking means steaming the potato separately and reassembling it, which costs you time and loses the crisp.
Do scuff the skin though. Rub each potato with the back of a spoon or the coarse side of a grater until the skin is rough and matte, not polished. Those scratches let moisture escape and give the oil and salt something to grip.
Peeling only makes sense when you want a soft, fully exposed surface for a specific dish. A peeled potato baked at 425°F dries out faster, so give it a shorter time and a butter or sauce at the end. For most purposes, skin on is the right call. If your kitchen routine leans more toward boiled sides, my timing guide for boiling potatoes for mashed potatoes covers the softer route in detail.
Should I Wrap a Potato Before Baking It?
Skip the foil for the best skin. Wrapping traps steam, so the potato cooks softer and the skin stays leathery instead of crisp. It is still a perfectly good method when you want a soft, creamy potato or when you are feeding someone who prefers tender skin over crunch.
| Method | Time at 425°F | Result | Best for |
|---|---|---|---|
| Unwrapped on a rack | 45 to 60 minutes | Crisp, dry, flaky skin | Steakhouse style, loaded potatoes |
| Fully wrapped in foil | 55 to 70 minutes | Soft, moist skin and creamy flesh | Large potatoes, mild texture preferences |
| Open-topped foil tent | 45 to 60 minutes | Crisp top, softer underside | Cooking a whole batch without much oiling |
| Parchment paper | 45 to 60 minutes | Same as unwrapped, easier cleanup | Sticky-sugar toppings, calmer kitchens |
One storage note if you do use foil: let the potato cool completely, unwrap it, and refrigerate it loose. Baked potatoes held warm in their foil wrappers in a cool room are a botulism risk, and refrigeration only helps if the foil comes off.
How to Tell When a Potato Is Done Baking
Slide a fork into the center of the potato with no resistance. That single test beats any timer, and it takes two seconds.
If the fork needs force, give it another five minutes. Three signals together mean it is done: the fork goes in easily, the skin looks dry and wrinkled rather than smooth and tight, and a gentle squeeze releases without feeling firm or rubbery. Squeeze only gently on a piping-hot potato.
If you want a number, a probe thermometer pushed into the center will read somewhere around 205 to 210°F when the starch has fully softened. Many home cooks who use one report the biggest improvement in their baked potatoes came from that check, and it is the only way to confirm what a cool-running oven actually delivered.
Cooking on a convection setting is faster. Drop the temperature by about 25°F and start checking 10 minutes early, since moving air both crisps the skin and speeds the interior.
Common Mistakes and How to Fix Them
The center is still hard after an hour. The potato was bigger than the time you used. Home ovens also commonly run 20 to 30 degrees cool, and potatoes packed close together bake in layers. Measure by weight instead of by size language, space them out, and verify your oven with a thermometer.
The skin is pale and soft. Too little oil or salt, or foil in the way. Oil the skin generously and salt before it goes in, not after.
The skin is tough and leathery. Usually foil, or an unpunctured potato that steamed in its own moisture. Use a rack, leave the skin exposed, and poke properly.
The bottom is soggy. The potato sat directly on the baking sheet. A wire rack lifts it so hot air reaches all sides and moisture escapes.
The potato burst in the oven. No fork holes. Six or eight piercings give expanding steam somewhere to go.
The interior is dense or gummy. It was undercooked, or you fluffed it too early. Wait for the fork test, then let the potato rest a few minutes off the heat.
You want it faster. Microwave the pierced potato for 4 to 5 minutes until barely tender, then finish it at 425°F for 20 to 25 minutes. The oven step is what restores the crisp skin. An air fryer at 425°F runs about 35 to 45 minutes for a medium potato, with the same poking and oiling.
Other Potato Dishes Worth Trying
Once your timing feels automatic, the same potato works as the base for plenty else. This hamburger potato casserole layers sliced potatoes and beef in one dish for a full dinner. When you want the oven doing double duty, this chicken breast bake at 400°F guide runs alongside it on the same night. And if sweet potatoes are more your speed, these sweet potato dinner recipes with ground beef use the same oven and very different timing.
Frequently Asked Questions
How long does it take to bake a potato at 425°F?
A medium potato takes 45 to 60 minutes at 425°F. Small potatoes finish around 40 to 45 minutes, large ones 55 to 65 minutes, and anything over a pound needs 65 to 80 minutes. Start checking with a fork at the low end of the range, because size varies more than any other factor.
Should I bake a potato at 425°F with or without foil?
Without foil for the crispest skin. Foil traps steam, so the skin stays soft and leathery and the potato needs another 10 minutes. Use foil when you want a soft, creamy texture, or when you are baking a very large potato. An open-topped foil tent splits the difference.
Do I need to pierce a potato before baking it?
Yes, always. Six to eight fork holes let expanding steam escape, and an unpunctured potato can burst inside the oven. Pierce from the top and a few times from the side so the center gets a path. This is the one prep step you should never skip.
Why is my baked potato still hard after an hour?
Usually the potato was bigger than the timing you used, or the oven runs cooler than its dial says. Space potatoes out so air moves around them, check with an oven thermometer, and test for fork-tender rather than watching the clock. A probe reading of 205 to 210°F in the center confirms it.
Can I reheat a baked potato in the oven or microwave?
Oven is better. Put the potato directly on the rack at 350°F for 15 to 20 minutes, and the skin crisps again. In the microwave, a whole potato takes about a minute per potato on high, but the skin turns soft. Either way, let the reheated potato cool fully before refrigerating.
Is 425°F too hot for a baked potato?
No. It is high enough to dry the skin and crisp it quickly, and low enough that the interior cooks through before the outside burns. Above 450°F the window narrows quickly and large potatoes burn outside before they soften inside. If your oven overshoots, drop to 400°F and add 10 minutes.
Conclusion
Start with one medium russet, washed but unpeeled, on a wire rack at 425°F for 45 to 60 minutes. Rub it with oil and coarse salt first, then use fork-tender and dry, wrinkled skin as your final checks instead of the timer. Once that timing feels easy, timing by weight takes all the guesswork out of it.
