I wrapped baked potatoes in foil for years because that’s how I saw it done growing up. Every one of them came out with soft, damp skin that nobody at my table wanted to eat.

The fix turned out to be the opposite of what I’d been doing. No foil at all, a hotter oven, and a thermometer instead of a guess.

Now the skin shatters a little when you press it open and the inside is dry and fluffy enough to take butter without going gluey. My kids eat the skins now, which tells you everything.

Why do you not wrap baked potatoes in foil?

Foil traps the steam coming off the potato as it bakes, and that steam keeps the skin soft and damp. Left bare in a 425°F oven, the surface dries out and crisps instead. Wrap it only if you actually want a soft skin.

Why This Recipe Works

A 425°F oven drives moisture out of the skin faster than it can collect, which is the whole difference between crisp and leathery. At 350°F the potato still cooks through, it just takes an extra 20 minutes and the skin never dries.
Russet potatoes are high in starch and low in moisture, and that ratio is what lets the inside go fluffy instead of dense. A waxy red potato baked the same way stays firm and a little wet no matter how long it sits in the oven.
Pulling the potatoes at 210°F is what separates a good baked potato from a great one. The starch granules need that much heat to swell and separate, so a potato can feel soft to a fork and still be waxy at the center.

I bought a cheap instant-read thermometer for chicken and ended up using it here more than anywhere else.

Why I Keep Coming Back to This One

Five minutes of actual work, and the oven does the rest without any attention from you.
Four ingredients, three of which are salt, oil, and a potato.
The skin comes out crisp enough to eat, which turns a side dish into most of a meal.
They hold in a warm oven while everything else finishes, so timing dinner gets easier instead of harder.

What Goes Into Baked Potatoes

4 medium russet potatoes (also sold as Idaho potatoes)
1 tbsp olive oil, or melted butter
1 tsp kosher salt, or more to taste
Butter, sour cream, chives, or shredded cheddar, for serving

Ingredient Notes

Russets are not interchangeable here. They’re the long, rough-skinned brown potatoes, and they’re high in starch and low in moisture, which is exactly what a baked potato needs.

Red potatoes and Yukon Golds are waxy, and they hold together beautifully in a potato salad for the same reason they stay dense and slightly wet in the oven. If russets are all your store labels as “baking potatoes,” that’s the same thing.

Olive oil and melted butter both work for the skins. Butter browns more and tastes richer, oil crisps a little cleaner and won’t burn at 425°F.

I go back and forth depending on what’s already out on the counter.

Use kosher salt if you have it. The larger flakes sit on the skin instead of dissolving into it, so you get actual seasoning on the part you’re trying to make worth eating.

Pick potatoes that are close to the same size. Two big ones and two small ones on the same sheet means the small pair is dry by the time the large pair is ready.

Step-by-Step Directions

Heat the oven to 425°F. Set a rack in the middle position. If you want the crispest possible skin, you’ll bake the potatoes directly on the rack, so leave room and slide a sheet pan onto the rack below to catch any drips.
Scrub and dry the potatoes. Run them under cold water and scrub the skins clean with a brush or a rough cloth. Then dry them completely with a towel. This step matters more than it sounds, because oil won’t stick to a wet skin and the water just turns to steam.
Pierce each potato 5 or 6 times. Use a fork and go in about a half inch, spacing the holes around the potato. This lets steam escape as the inside cooks. Skip it and you risk a potato splitting open in the oven.
Oil and salt the skins. Rub each potato all over with olive oil, using your hands so you get an even, thin coat. Sprinkle generously with kosher salt and turn the potato to catch all sides.
Bake 45 to 60 minutes. Place them directly on the oven rack, or on a sheet pan if you’d rather. Start checking at 45 minutes. Medium potatoes usually land close to 50, and large ones can take the full hour.
Check the center, not the clock. Slide an instant-read thermometer into the thickest part. You want 210°F. A fork should also slide in with no resistance, but the thermometer is what tells you the inside has gone fluffy rather than just soft.
Cut and fluff right away. Slice a cross into the top of each potato, then squeeze the ends toward each other to push the inside up and open. Doing this straight out of the oven lets the trapped steam escape instead of turning the flesh gummy.

Tips for Success

Don’t wrap them in foil unless you want soft skin. Foil holds steam against the potato, and that steam is the enemy of everything you’re trying to do here.
Baking directly on the rack gives the crispest all-over skin because air moves under the potato too. A sheet pan is easier to handle and the only real cost is a slightly softer underside.
If dinner isn’t ready, the potatoes hold well in a 200°F oven for 20 to 30 minutes without drying out.
Salt the skin heavily. Most of it ends up on your fingers and the pan, and the rest is what makes the skin taste like something.
A second round of oil and salt at the 30-minute mark gives a noticeably crisper skin. I only bother when the potatoes are the point of the meal.
Cut the potato open the moment it leaves the oven. Five minutes sitting closed is enough to steam the inside back into something dense.

Make-Ahead and Leftovers

Let leftover potatoes cool, then refrigerate them in an airtight container for 3 to 4 days. Leave them whole if you can, since a cut potato dries out at the edges and picks up refrigerator smells faster.

To reheat, put them back in a 400°F oven for 15 to 20 minutes, until the center is hot all the way through. The skin crisps up again in the dry heat, which a microwave can’t do.

A microwave will warm the inside in about 2 minutes, but the skin comes out soft and a little rubbery. Cold leftover baked potatoes are also the best possible start for hash browns or a skillet of breakfast potatoes, since the cooked starch browns faster than raw potato does.

What to Serve With Baked Potatoes

Steak or a roast chicken, because the oven is already hot and a baked potato needs the drippings more than any other side does.
Chili or beef stew, spooned right into the open potato so the skin holds it all.
A crisp green salad, which cuts through the butter and sour cream without competing with anything.
Broccoli and cheddar, either alongside or piled straight into the potato for a meal that doesn’t need meat.

Equipment Worth Having

A stiff vegetable brush for scrubbing the skins, since you’re going to eat them and dirt is not seasoning.
An instant-read thermometer, the only way to know you’ve hit 210°F without cutting the potato open and losing the steam.
A rimmed sheet pan, either to bake on or to slide under the rack as a drip catcher.
A dish towel you don’t mind getting dirty, for drying the potatoes properly before they’re oiled.

FAQ

What temperature should a baked potato be inside? Aim for 210°F at the center. That’s well past the point where the potato is safe to eat, and it’s the heat the starch needs to go fully fluffy. Anything much under 200°F tends to feel soft on the outside but waxy in the middle.

How long does it take to bake a potato at 425°F? Between 45 and 60 minutes for medium russets. Size matters more than anything else, so start checking at 45 minutes and go by the thermometer instead of the clock.

Can I bake potatoes at a lower temperature? Yes. At 400°F they take about 45 to 55 minutes, at 375°F about 50 to 60, and at 350°F closer to 60 to 75. The lower the oven, the softer the skin, which is worth knowing if you’re already baking something else.

Do I have to pierce baked potatoes? Pierce them. It takes ten seconds and lets steam escape as the inside cooks, which keeps a potato from splitting open in your oven.

Why is my baked potato skin soggy? Almost always foil, or a wet potato that went into the oven without being dried. Both trap moisture at the surface, and neither can be fixed once the potato is baked.
