At 325°F (163°C), bake a medium russet potato for about 1 hour 35 minutes to 1 hour 45 minutes, until its skin is crisp and the center is tender. This simple oven method uses whole potatoes, a little oil, and salt; it works well when a lower oven temperature suits the rest of a meal.
Ingredients
- 4 medium russet potatoes, about 8–10 oz (225–280 g) each
- 2 tablespoons olive oil or another neutral cooking oil (30 ml)
- 1 teaspoon kosher salt (5 g), or ½ teaspoon fine table salt (about 3 g)
- ¼ teaspoon freshly ground black pepper (about 0.5 g), optional
- 2 tablespoons butter for serving (28 g), optional
Instructions
- Heat the oven. Set a rack in the middle of the oven and preheat it to 325°F (163°C). Put a rimmed baking sheet on the rack or line one with parchment if you want to catch any oil or salt that falls off. The sheet is helpful but not essential; the potatoes can also sit directly on the oven rack.
- Prepare the potatoes. Scrub the potatoes under cool running water, removing any dirt from the skins. Dry them thoroughly with a clean towel. Dry skins brown more readily than wet skins, and moisture left on the surface can make them softer. Trim away any bruised or damaged spots, but leave the skins on.
- Pierce and season. Prick each potato four or five times with the tines of a fork, making shallow holes around the potato. This lets steam escape as the centers heat. Rub the skins all over with the oil, then sprinkle on the salt and, if using, pepper. Keep the potatoes whole; cutting them before baking changes the cooking time and produces a different, less fluffy texture.
- Bake until tender. Arrange the potatoes with a little space between them on the baking sheet or directly on the oven rack. Bake for about 1 hour 40 minutes. Start checking at 90 minutes because potatoes vary in diameter, oven accuracy, and moisture. A medium potato is done when a thin knife or skewer slides through the center without resistance and the potato feels soft when gently squeezed with an oven mitt. If it still feels firm in the middle, return it to the oven and check again after 5 to 10 minutes.
- Rest and serve. Transfer the potatoes to a plate or board and let them stand for 5 minutes so they are easier to handle. Cut a lengthwise slit through the top of each potato, then gently press the ends toward the middle to open it. Fluff the inside with a fork and add butter or your preferred toppings while hot.
Tips
- Choose potatoes of similar size. The time in this recipe is for medium russets weighing roughly 8–10 ounces (225–280 g) apiece. If one potato is noticeably larger, it can need another 10–20 minutes; smaller ones may finish sooner. Bake size-matched potatoes together and remove individual potatoes as they become tender rather than waiting for the largest one.
- Use a doneness cue, not the clock alone. Oven thermostats and potato sizes differ, so a time range is more dependable than assuming every potato is ready at exactly 100 minutes. The center should be soft all the way through, with no hard or waxy-feeling core. A food thermometer can also help assess texture: many cooks find a center temperature around 205–210°F (96–99°C) gives a fluffy result, but tenderness is the key test.
- Adjust the salt to your preference. Kosher salt crystals vary by brand, while fine table salt packs more tightly. Use the smaller listed amount if using table salt, or season lightly before baking and add more at the table. Olive oil gives the skin a mild fruity flavor; neutral oil works just as well and keeps the potato flavor more prominent.
- Skip wrapping in foil for a crisp skin. Foil traps moisture and tends to steam the skin instead of letting it dry and crisp. If you need to use foil to keep potatoes warm briefly, unwrap them promptly afterward; do not leave cooked potatoes sitting at room temperature for an extended period.
Serving Suggestions
Serve each potato hot as a side dish or make it the center of a simple meal. Butter, sour cream, sliced scallions, and black pepper are classic toppings; shredded cheddar, chopped chives, or crisp cooked bacon can make the potato more substantial. Offer toppings separately if people are serving themselves, and split the potato open just before eating so its steam escapes and the toppings can melt into the fluffy center.
A baked potato pairs naturally with roast chicken, grilled fish, steak, or a green salad. For a meat-free plate, add steamed broccoli and a spoonful of cottage cheese, or serve it with beans and salsa. If you are preparing a full meal, potatoes can bake alongside other dishes at 325°F (163°C), but use the potato’s tenderness—not another dish’s schedule—to decide when they are ready.
Variations
Use another potato variety: Yukon Gold potatoes have a thinner, more buttery-tasting skin and a creamier, less dry interior than russets. They can be baked using the same method, but smaller ones may finish sooner, so check them early. Red potatoes are also suitable, though their firm, waxier flesh will not become as light and fluffy as a russet.
Make an herbed skin: Mix the oil with ½ teaspoon dried rosemary or thyme (about 0.5 g) before rubbing it over the potatoes. Dried herbs are easy to use here; fresh herbs can scorch during a long bake, so save those for finishing. A pinch of smoked paprika or garlic powder adds a savory note without changing the basic cooking method.
Try a dairy-free finish: Replace the butter with a drizzle of olive oil, or use a plant-based butter alternative. For a loaded version, add cooked beans, salsa, and avocado after baking. Keep wet toppings off the skin until serving if you want it to stay crisp.
Storage and Reheating
For food safety, refrigerate leftover baked potatoes within 2 hours of cooking. Remove any foil, let the potatoes stop steaming heavily, and place them in a covered container in the refrigerator. Use them within 3–4 days. Avoid leaving potatoes warm in a turned-off oven for hours, and do not store cooked potatoes at room temperature overnight.
To reheat, cut the potato in half or leave it whole, place it in an oven-safe dish, and warm it at 350°F (177°C) until hot throughout. A whole refrigerated potato may take 20–30 minutes; halves usually take less time. For a faster option, microwave it in short intervals, turning it once, until the center is steaming hot. USDA FSIS advises reheating leftovers to 165°F (74°C); check the thickest part with a food thermometer if you need to confirm the temperature. The microwave softens the skin, while the oven helps it dry out again.
You can freeze a baked potato, although its texture may become grainier or wetter after thawing. For better results, freeze the scooped-out flesh separately from the skin in a sealed freezer-safe container, then use it in mashed potatoes or soup. Thaw it in the refrigerator and reheat it thoroughly; quality is best when frozen portions are used within about 1–2 months.
Frequently Asked Questions
How long does a baked potato take at 325°F?
A medium russet potato generally takes about 1 hour 35 minutes to 1 hour 45 minutes at 325°F (163°C). Begin checking at 90 minutes, since size and oven differences affect the timing. A particularly large potato can take longer, while a small one may be ready sooner. The center should feel tender when pierced with a knife or skewer.
Can I bake potatoes at 325°F if another dish is in the oven?
Yes. A 325°F (163°C) oven is suitable for baking potatoes, and you can cook them alongside another dish if the oven temperature is appropriate for both. Keep space around the potatoes so hot air can circulate. Their cooking time may shift slightly if the oven is crowded or frequently opened, so check for tenderness rather than relying only on the timer.
Should I wrap baked potatoes in foil?
No foil is needed for this recipe. Leaving the skins exposed allows them to dry and become crisper; foil holds in steam and makes the skins softer. If you prefer a soft skin, foil is an option for baking, but it will not make the potato cook reliably faster. Unwrap cooked potatoes promptly and refrigerate leftovers within 2 hours.
Do I need to pierce a potato before baking it?
Pricking the skin several times with a fork gives steam a way to escape as the potato heats. The holes should be shallow and spread around the potato; there is no need to cut it open. Piercing does not replace checking that the potato is fully tender, and the potato should still be baked whole for the fluffy center this recipe aims for.
Can I bake potatoes at 325°F without oil?
Yes. The oil helps the skin brown and gives the salt something to cling to, but it is not required for the potato to cook. Omit it for a drier, less glossy skin, or rub the potato with a small amount of water before adding salt so some seasoning sticks. The interior will still become tender when baked long enough.
Why is my baked potato still hard in the middle?
It probably needs more time, especially if the potato is large or the oven runs cooler than its setting. Return it to the oven and check every 5–10 minutes until a knife reaches the center easily. If the outside is already very dark, loosely cover the potato with foil for the remaining bake, but avoid tightly wrapping it. Next time, choose potatoes closer in size and allow for the full baking window.
