How Long to Cook a Large Baked Potato

A large baked potato is a whole russet potato baked until its skin is crisp and its center is tender and fluffy. At 400°F (200°C), plan on about 60–75 minutes for a 12–14-ounce (340–400 g) potato; this simple method shows you how to check doneness and serve it.

Ingredients

4 large russet potatoes, 12–14 oz (340–400 g) each
1 tbsp olive oil (15 ml)
1 tsp fine salt (5 g)
4 tbsp unsalted butter (56 g), for serving, optional
1/2 cup sour cream (120 g), for serving, optional
2 tbsp chopped fresh chives (6 g), for serving, optional
1/4 tsp ground black pepper (0.5 g), or to taste, optional

Instructions

Heat the oven to 400°F (200°C), placing a rack in the middle. If you want to catch any oil or potato drips, set a rimmed baking sheet on the rack or on the rack below; the potatoes can bake directly on the oven rack for better air circulation. Allow roughly 10 minutes to wash, dry, pierce, and season the potatoes while the oven heats.
Scrub the potatoes under cool running water to remove dirt, then dry them very thoroughly with a clean towel. Dry skin browns and crisps more readily than damp skin. Use a fork to pierce each potato 6–8 times, distributing the holes over its surface. These small vents let steam escape as the potato cooks.
Rub each potato with a thin coating of olive oil and sprinkle the skins with salt. The oil helps the skins brown and gives the salt something to cling to. Set the potatoes directly on the oven rack, leaving space between them so hot air can circulate. Do not wrap them in foil: foil traps moisture and produces softer, more steamed skins.
Bake for 60 minutes before checking. A typical large potato will take about 70 minutes total, while especially thick or heavy ones may need up to 75 minutes. If you are baking potatoes of noticeably different sizes, start checking the smaller ones first and remove each one as it becomes tender rather than waiting for the largest.
Check doneness by pushing a thin skewer or the tip of a small knife into the center of the thickest part. It should slide in easily, with little resistance, and the potato should feel soft when gently squeezed with an oven mitt. If the center still feels firm or the skewer catches, return it to the oven and check again after 5–10 minutes. A food thermometer inserted into the center often reads around 205–210°F (96–99°C) when the interior is fluffy, but tenderness is the most useful practical test.
Move the potatoes to plates, make a lengthwise cut through the top, and gently press the ends toward the center to open them up. Fluff the inside lightly with a fork, then add butter, sour cream, chives, black pepper, or toppings of your choice. Serve while hot.

Tips

Choose potatoes with similar sizes. The 60–75-minute estimate is for large russets weighing about 12–14 ounces each. A potato that is much smaller can finish sooner; a very wide or extra-heavy one can take longer, even if its weight seems close. When cooking several, check each one individually and remove it as soon as the center is tender.

Dry the skins and leave room around each potato. Water left on the surface slows browning, and potatoes crowded together can cook unevenly. Direct contact with the oven rack gives heat room to move around the skin. If you prefer not to place food on the rack, use a baking sheet, but expect the undersides to be a little less crisp.

Use russets for the classic fluffy texture. Their dry, starchy interior separates easily when fluffed. Yukon Gold or other waxier potatoes can be substituted, but they tend to have a denser, creamier center and may not open into the same fluffy texture. Keep the same doneness test rather than relying only on the clock.

Skip foil unless a soft skin is what you want. Foil is not needed to bake a potato and prevents the skin from drying and crisping. If you do use foil for a softer skin, unwrap the potato after baking and do not leave it sitting at room temperature in the foil; refrigerate leftovers promptly.

Serving Suggestions

For a straightforward side, top each hot potato with about 1 tablespoon (14 g) butter, a spoonful of sour cream, chopped chives, and black pepper. For a more filling meal, add cooked broccoli and shredded cheddar, or spoon over chili and finish with a little sour cream. Keep moist toppings separate until serving so the skin does not soften while the potatoes wait.

Baked potatoes also pair well with roasted vegetables, a crisp green salad, grilled chicken, or beans. If serving them as a side, one large potato is usually a generous portion; for a lighter meal, split one between two people and offer a few toppings. Set out toppings in small bowls so everyone can choose, and put cold toppings on just before eating.

Variations

Garlic-herb: Mix softened butter with a little minced garlic and chopped parsley, then spoon it into the split potato. Garlic can scorch if rubbed onto the skin for the full bake, so it is better added after cooking. Chives, dill, or thyme also work, though each gives the topping a different flavor.

Cheesy broccoli: Add warm cooked broccoli florets and shredded cheddar to the opened potato. If you want melted cheese, return the topped potato to the oven for a few minutes, just until the cheese softens. This extra warming time is optional; the potato itself is done when its center is tender.

Smoky or dairy-free: For a smoky topping, add a pinch of smoked paprika and sliced scallions, or use cooked beans and salsa. To make the potato dairy-free, replace butter with olive oil and use a dairy-free sour cream alternative, or choose toppings such as avocado, salsa, and herbs. These changes affect the topping, not the oven time.

Microwave-then-oven: When time is short, pierce and microwave a potato until it is partly tender, turning it once, then finish it in a hot oven until the skin is crisp and the center is completely tender. Microwave power and potato size vary, so check often and treat the oven finish as a texture step rather than assuming a fixed time. For the most even, hands-off result, use the oven-only method above.

Storage and Reheating

Refrigerate cooked potatoes within 2 hours of baking. Let them stop steaming briefly, then place them in a covered container or wrap them and refrigerate at 40°F (4°C) or below. Use within 3–4 days. Store toppings separately when practical, since sour cream, butter, and fresh herbs can make the potato soggy or lose their best texture during storage. Do not leave a baked potato at room temperature for an extended period.

To reheat, remove any foil and warm the potato in a 350°F (175°C) oven for about 15–25 minutes, depending on its size and whether it is whole or cut; cover loosely if the skin is already dark. A microwave is quicker: cut the potato open, cover it loosely, and heat in short intervals, turning or repositioning it as needed. The USDA FSIS safe minimum for reheated leftovers is 165°F (74°C); check the center with a food thermometer, especially if reheating a stuffed potato or several portions together.

You can freeze a baked potato, though thawing tends to make the inside grainier and the skin softer. For best results, freeze it without sour cream or other toppings, wrapped once cool, and use within about 2 months for quality. Thaw it in the refrigerator, then reheat until hot throughout. If texture matters most, refrigerating and using it within a few days is preferable.

Frequently Asked Questions

How long does a large baked potato take at 400°F?

A 12–14-ounce (340–400 g) russet usually takes 60–75 minutes at 400°F (200°C), with about 70 minutes a useful planning estimate. Oven accuracy, potato shape, and how many potatoes are baking can shift the timing. Begin checking at 60 minutes and continue in 5–10-minute increments until a skewer slides easily into the center.

How can I tell when a baked potato is done?

Test the thickest part with a skewer or small knife: it should pass through the center without a firm spot. The potato should also yield when gently squeezed with an oven mitt. A thermometer may show roughly 205–210°F (96–99°C) in a fluffy potato, but a tender center matters more than reaching a particular temperature.

Should I bake a potato at 350°F or 400°F?

Both temperatures work. At 400°F (200°C), a large potato generally takes about 60–75 minutes; at 350°F (175°C), allow roughly 75–90 minutes and use the same tenderness check. The lower temperature can be convenient when another dish is already in the oven, but it usually takes longer to crisp the skin.

Is it better to bake potatoes on a rack or a pan?

A rack allows hot air to circulate around the entire potato and tends to give the most even skin. A baking sheet is also fine and makes handling drips easier, though the side touching the pan may brown differently. Avoid crowding potatoes on either surface, and do not rely on foil for crisp skin.

Can I prepare the potatoes ahead of time?

You can scrub and dry the potatoes earlier in the day, then refrigerate them uncovered or loosely covered and season just before baking. Avoid piercing them far in advance, since exposed cut surfaces can dry out. Fully baked potatoes can also be refrigerated within 2 hours and reheated within 3–4 days, though freshly baked skins are crispest.
