How Long to Bake a Potato | Perfect Timing Every Time

A standard russet potato takes 45 to 60 minutes to bake at 400°F to 450°F, depending on its size and your preferred skin texture.

The exact time depends on three things: the potato’s weight, your oven temperature, and whether you want a crispy skin or a tender one. Here’s how to nail the timing every time, no guessing required.

What Determines Baking Time?

Size is the biggest variable. Oven temperature matters just as much—450°F crisps the skin faster but shortens the window between done and overdone, while 350°F is more forgiving but takes longer.

A potato is fully baked when its internal temperature reaches 205°F. At that point, the starches have fully gelatinized, creating that light, fluffy texture. A fork should slide in with almost no resistance. If the fork meets any firmness, it needs more time.

Baking Temperatures and Their Best Uses

Choose your temperature based on what you want from the skin and how much time you have.

• 450°F produces the crispiest, brownest skin. Large russets (8–10 ounces) take 45–55 minutes. This is the go-to for classic loaded baked potatoes where the skin is part of the experience.
• 400°F is the all-purpose standard. It balances skin crispness with a wider doneness window.
• 350°F is the low-and-slow option. Medium potatoes need 60–90 minutes. The skin stays softer, but you have a much larger margin of error on timing.
• 425°F convection cuts time by 5–10 minutes. For halved or cut potatoes, the USDA recommends 20–25 minutes at 425°F for a golden-brown surface.

If your potato is larger than 12 ounces, plan for 75 minutes minimum at 400°F. Check it at 70 minutes with a fork and an instant-read thermometer. Smaller potatoes under 5 ounces can be done in under 40 minutes—check early.

How to Bake a Potato, Step by Step

These steps work for any conventional oven. Convection ovens should reduce bake time by 5–10 minutes at the same temperature, and the potatoes may brown faster.

1. Preheat to 450°F for crisp skin or 400°F for standard. Rack in the center position.
2. Scrub and dry the potato under cold water. Dry it thoroughly with a towel—wet skin won’t crisp.
3. Pierce the potato 6–8 times with a fork to vent steam. Skipping this can cause bursting in the oven.
4. Optional for crispness: Rub with ½ tablespoon olive oil and 1 teaspoon salt. This creates a seasoned, crispy skin.
5. Place directly on the center oven rack—no baking sheet needed. Air circulating around the potato cooks it evenly. If using a sheet, flip the potato every 20 minutes.
6. Bake according to size and temperature. At 400°F: 60–65 minutes for large (8–10 oz). At 450°F: 45–55 minutes for large.
7. Check doneness with an instant-read thermometer: 205°F is ideal. Alternatively, a fork should slide in with no resistance. Test at the thickest part.
8. For extra-crisp skin: brush with additional oil and bake 2–3 more minutes.
9. Rest 3–5 minutes before cutting. Letting steam settle keeps the texture fluffy. Cut an X in the top, pinch the ends, and push to open.

Common mistakes include skipping the pierce step (bursting), using wet potatoes (no crisp skin), and cutting immediately after pulling from the oven (steam escapes, leaving a dry interior). Let the potato rest.

FAQs

Does wrapping a potato in foil speed up baking?

No. Foil traps steam and steams the skin rather than crisping it. It also increases bake time slightly. Use foil only if you want soft, tender skin—skip it for a crispy exterior.

Can I bake a potato at 350°F?

Yes. The skin stays softer and the timing is more forgiving, but the internal temperature still needs to reach 205°F for a fluffy texture.

How do I reheat a baked potato?

Wrap it in foil and reheat at 325°F for about 35 minutes. Avoid high heat—it dries the potato out. For food safety, hold baked potatoes at 135°F or higher if serving later.
