A russet baked potato takes about 50–60 minutes in a 425°F (220°C) oven when it weighs 8–10 ounces (225–280 g); allow about 55 minutes for a typical potato. Baking it uncovered with a little oil gives the skin a crisp finish while the starchy center turns tender and fluffy.
Ingredients
- 4 medium russet potatoes, 8–10 ounces (225–280 g) each
- 1 tablespoon neutral oil or olive oil (15 ml)
- ½ teaspoon kosher salt (about 3 g), plus more to taste
- ⅛ teaspoon ground black pepper (about 0.3 g), optional
Instructions
- Heat the oven. Set a rack in the middle of the oven and preheat it to 425°F (220°C). The potatoes bake directly on the rack, so there is no need to heat a baking sheet. If you prefer to catch any oil drips, put a rimmed tray on the rack below the potatoes, not underneath them in a way that blocks airflow.
- Wash and dry the potatoes. Scrub each potato under cool running water to remove dirt, then dry it thoroughly with a clean towel. Dry skin browns and crisps more readily than damp skin. Choose potatoes that are similar in size so they finish at roughly the same time. If one is much larger, it may need an additional 10–15 minutes.
- Prick, oil, and season. Pierce each potato four or five times with the tines of a fork, making shallow holes around its surface. This lets steam escape as it cooks. Rub the skins with the oil, then sprinkle with salt and, if using, pepper. Use only a thin coating; excess oil can drip and make the skin greasy.
- Bake until tender. Place the potatoes directly on the oven rack with a little space between them. Bake for 50–60 minutes, starting to check at 50 minutes. A fork or thin skewer should slide into the center with little resistance, and the potato should feel soft when gently squeezed with an oven mitt. For a particularly fluffy center, a food thermometer inserted into the thickest part will often read about 205–210°F (96–99°C); tenderness is the more useful final check.
- Give larger potatoes more time if needed. If the center still feels firm, return the potato to the oven and check again after 5 minutes. Repeat as needed rather than turning up the heat, which can darken the outside before the center is ready. Very large russets, around 12 ounces (340 g) or more, can take 65–75 minutes. Smaller potatoes may be done in 40–50 minutes.
- Rest and serve. Transfer the potatoes to a plate or board and rest them for 10 minutes. Make a lengthwise cut through the top, then press the ends gently toward the center to open the potato. Fluff the inside with a fork and add toppings while it is hot.
Tips
- Use size as your timing guide. The clock is an estimate because russets vary in weight, shape, and starting temperature. A long, narrow potato may cook sooner than a compact potato of the same weight. If you are baking potatoes for a group, pick ones close in size and check each one separately; take out finished potatoes and leave the firmer ones in the oven.
- Dry the skin well. Water left on the potato surface can soften the skin. A thorough towel-dry before applying oil is a small step that makes a noticeable difference to the exterior.
- Skip the foil for crisp skin. Foil traps moisture and steams the potato, so the skin will be soft rather than crisp. Foil is a preference some cooks use when they specifically want a softer skin, but it does not make the potato cook instantly. Pricking the skin and baking uncovered is a straightforward approach for the crisp-edged result in this recipe.
- Adjust the seasoning to suit your toppings. Kosher salt gives the skin a lightly seasoned finish; fine table salt is more concentrated by volume, so use a scant ½ teaspoon (about 2.5 g) if substituting. If serving with salty cheese or other savory toppings, start with less salt and add more at the table.
Serving Suggestions
Serve each potato hot, split down the middle and fluffed with a fork. A classic topping combination is butter, sour cream, sliced green onion, and black pepper. For a richer version, add shredded cheddar and let the heat of the potato soften it before spooning on sour cream. Keep toppings in small bowls so everyone can dress their own potato and adjust the amount to taste.
A baked russet can also be the base of a more substantial meal. Add steamed broccoli and a little grated cheese, or top it with cooked beans, salsa, and avocado. A simple green salad, crisp slaw, or bowl of soup makes a good side when the potato is served as part of a larger dinner. If serving several potatoes at once, open and fluff them just before they reach the table; they hold heat better while whole than after they have been cut.
Variations
Extra-crisp skins: After baking, brush the potatoes very lightly with another teaspoon of oil (5 ml total per potato is plenty) and return them to the oven for 5 minutes. This is useful if the skins look pale, but it is optional; the original oil coating is enough for a pleasantly crisp exterior.
Salt-crusted finish: Use the same amount of oil and salt the outside a little more generously, then serve with unsalted butter or a mild topping. The salt seasons the peel, which is edible, as well as the potato near the surface. If you do not eat the skin, keep the original seasoning amount so the interior is not overly salty.
Herb and garlic topping: Stir 1 tablespoon chopped chives or parsley (about 3 g) into 2 tablespoons sour cream (30 g), with a small pinch of garlic powder. Add it after baking rather than putting fresh herbs on the potato before it goes into the oven, where they can dry out or scorch.
For a softer skin: You can wrap the potatoes loosely in foil before baking, but expect a softer, less crisp peel. The cooking time is still determined by the potato’s size and tenderness, so use the same doneness checks. Do not wrap tightly if you want browned skin, and do not leave a cooked potato sitting in foil at room temperature.
Storage and Reheating
Refrigerate leftover potatoes within 2 hours of baking. Remove any foil, let the potatoes stop steaming, and place them in a covered container in the refrigerator. They keep for 3–4 days. For the best texture, store them whole and add sour cream, cheese, or other toppings after reheating rather than before. A cut potato can be stored too, though its exposed center may dry out more quickly.
To reheat a whole potato in the oven, place it on a tray in a 350°F (175°C) oven for about 15–20 minutes, or until the center is hot. A microwave is quicker: split the potato, place it on a microwave-safe plate, cover loosely, and heat for 1–2 minutes; continue in short bursts if needed, turning or rearranging the pieces for even heating. USDA FSIS guidance is to reheat leftovers to 165°F (74°C); check the center with a food thermometer, especially when reheating more than one potato.
You can freeze baked potatoes, though thawed potatoes may be a little grainier or less fluffy. Cool them promptly, wrap individually, and freeze for up to about 2–3 months for best quality. Thaw overnight in the refrigerator and reheat until steaming hot throughout, checking that the center reaches 165°F (74°C). Freezing is most convenient for potatoes you plan to mash or use in another dish.
Frequently Asked Questions
How long does a russet potato take at 400°F?
At 400°F (200°C), a medium russet usually takes about 55–70 minutes, depending on its size and shape. Start checking near the shorter end of that range and continue baking until a fork slides into the center easily. A lower oven temperature may give the skin a little less crispness than the 425°F method, but it works well if another dish needs the oven at 400°F.
How long does it take at 350°F?
At 350°F (175°C), allow roughly 70–90 minutes for an 8–10-ounce (225–280 g) potato. Check it for tenderness rather than relying only on the clock, since large potatoes can take longer. This lower temperature is useful when coordinating with a roast or casserole already cooking in the oven.
Should I wrap a russet potato in foil?
Not for crisp skin. Foil holds moisture close to the potato and produces a softer peel, while baking directly on the rack lets the skin dry and brown. Foil can be used if you prefer the softer texture, but it does not remove the need to check whether the center is tender.
Can I bake russet potatoes ahead of time?
Yes. Bake them until tender, then refrigerate within 2 hours and use within 3–4 days. Reheat in the oven or microwave until the center reaches 165°F (74°C), then add fresh toppings. For the nicest contrast between skin and fluffy interior, serve them soon after reheating rather than holding them warm for a long time.
Why is my baked potato still hard in the middle?
It most likely needs more time, especially if it is large or unusually thick. Return it to the oven and check every 5 minutes until a fork or skewer reaches the center easily. A dark, browned exterior does not guarantee the middle is cooked, so do not judge doneness by skin color alone.
Can I bake several potatoes at once?
Yes. Leave space around each potato so hot air can circulate, and avoid stacking them. A full oven may take a little longer to recover its temperature after the door is opened, but the main factor is still each potato’s size. Check the potatoes individually and remove any that become tender before the others.
