A large baked potato is a whole russet potato roasted until its skin is crisp and its center is light and fluffy. At 425°F (220°C), allow about 65 minutes for a 12-ounce (340 g) potato, then check that it is tender; extra-large or especially thick potatoes can take longer.
Ingredients
- 1 large russet potato, about 12 oz (340 g)
- 1 tsp olive oil (5 ml)
- 1/4 tsp kosher salt (about 1.5 g), or to taste
Instructions
- Heat the oven. Set a rack in the middle of the oven and preheat to 425°F (220°C). Let the oven reach temperature while you prepare the potato so the baking time starts in a properly heated oven.
- Wash and dry the potato. Scrub the skin under cool running water to remove dirt, then dry it thoroughly with a clean towel. A dry surface helps the oil coat the skin evenly and encourages it to crisp rather than steam.
- Prick and season. Pierce the potato all over with a fork, making about 8 to 10 shallow holes. Rub the skin with the olive oil and sprinkle with salt. Pricking gives steam a way to escape during baking; do not cut the potato open before it goes into the oven.
- Bake directly on the rack. Place the potato on the oven rack, with a sheet pan on the rack below if you want to catch any drips. Bake for about 65 minutes. Start checking at 60 minutes; a thicker potato may need 5 to 10 more minutes. Avoid wrapping it in foil, since foil traps moisture and produces softer skin.
- Check that it is tender. The potato is ready when a thin knife or skewer slides into the center with very little resistance and the skin feels crisp. For a temperature check, the center is generally fluffy around 205–210°F (96–99°C), though texture is the most useful cue. If the middle still feels firm, return it to the oven and check again after 5 minutes.
- Open and serve. Transfer the potato to a plate and let it stand for about 2 minutes so it is easier to handle. Cut a slit lengthwise through the top, gently press the ends toward the center to loosen the flesh, and add toppings while it is hot.
Tips
- Choose the right potato. Russets, also called Idaho-type baking potatoes in some shops, have a relatively starchy interior that turns fluffy in the oven. A waxier potato such as a red or new potato can still be baked, but its center will be denser and less likely to separate into fluffy flakes. For a consistent result, select one potato close to 12 oz (340 g) and of fairly even thickness.
- Dry the skin well. Water left on the outside can slow crisping. If you wash the potato ahead, dry it and leave it uncovered in the refrigerator until you are ready to cook, or dry it carefully just before oiling. Do not use a wet potato as a reason to add more oil; a teaspoon is enough for a thin coating.
- Use a thermometer or a skewer, not the clock alone. Oven calibration, potato shape, and starting temperature all affect the timing. A long, narrow potato can finish sooner than a round potato of the same weight. Begin checking at 60 minutes and add time in short increments rather than assuming every large potato needs exactly the same bake.
- Skip the foil for crisp skin. Foil keeps moisture close to the potato, so the skin tends to soften. If you prefer a soft skin, foil is an option, but the potato may take longer to cook; check the center for tenderness instead of relying on the unwrapped timing. Do not leave a cooked potato sitting at room temperature for an extended period.
Serving Suggestions
Serve the potato as a simple side with a little butter, black pepper, and chopped chives, or make it a meal by splitting it open and adding a generous topping. Sour cream or plain yogurt gives a cool, tangy contrast to the hot, starchy center. Grated cheddar, sliced green onion, steamed broccoli, sautéed mushrooms, or a spoonful of salsa are other easy additions. Add delicate toppings after baking so they do not dry out in the oven.
For a more filling plate, pair the potato with a green salad, roasted vegetables, or a bowl of soup. If serving several people, put toppings in separate bowls and let everyone build their own. Keep hot toppings hot and chilled toppings refrigerated until serving, and avoid leaving topped potatoes out for more than 2 hours.
Variations
Extra-crisp skin: After washing, dry the potato especially well, rub it with oil, and season with salt. Bake it uncovered directly on the oven rack. This is the method in the recipe and gives the best contrast between a crisp exterior and fluffy flesh. If you are cooking several potatoes, leave space around each one so hot air can circulate.
Oil-free potato: Bake the scrubbed, dried potato without oil or salt. The skin will be drier and less richly crisp, but the center cooks in much the same way. Season the flesh after opening with butter, olive oil, or another topping if desired.
Garlic-herb finish: Mix softened butter with a little minced garlic and chopped parsley, chives, or thyme, then spoon it into the split potato after baking. Adding fresh garlic before a long bake can make it bitter or overly browned, so it works better as a finishing flavor.
Smoky or spicy topping: Sprinkle the finished potato with smoked paprika, chili flakes, or a few drops of hot sauce. You can also use plain Greek yogurt in place of sour cream; it tastes tangier and thicker. These are topping changes rather than changes to the baking time.
Storage and Reheating
For food safety, refrigerate leftover baked potato within 2 hours of cooking. If it was baked or served in foil, remove the foil before refrigerating. Store the potato in a covered container in the refrigerator for 3 to 4 days. Keep toppings such as sour cream separate when possible, since they can make the potato soggy and may not reheat well. Discard a potato that has been left at room temperature longer than 2 hours.
To reheat, cut the potato in half or into thick pieces so it warms more evenly. Use a 350°F (175°C) oven for about 15 to 20 minutes, or microwave it in short intervals, turning or rearranging the pieces as needed. Reheat leftovers to 165°F (74°C), checking the center with a food thermometer. The oven helps the skin regain some crispness; the microwave is faster but usually leaves the skin soft. Add fresh toppings after reheating.
You can freeze a baked potato, though thawed potato flesh may be softer or slightly grainier. For better texture, scoop the cooled flesh into a freezer-safe container and freeze it for up to 2 months. Thaw it in the refrigerator and reheat to 165°F (74°C), or use it in soup or mashed potato dishes. Whole baked potatoes can also be frozen, but their skins and centers are more likely to soften after thawing.
Frequently Asked Questions
How long does a large baked potato take at 425°F?
A large potato around 12 oz (340 g) usually takes about 60 to 75 minutes at 425°F (220°C), with roughly 65 minutes as a useful starting point. A wider or heavier potato may take longer, so check for a tender center rather than serving it just because the timer rang.
Should I bake a potato at 400°F or 425°F?
Either temperature works. At 425°F (220°C), a large potato often takes about 60 to 75 minutes; at 400°F (205°C), expect it to take somewhat longer, often around 70 to 90 minutes depending on its size. The hotter oven tends to crisp the skin more quickly. Whatever temperature you choose, leave space around the potato and use the tenderness test.
Is it better to wrap a baked potato in foil?
Not if you want crisp skin. Foil traps steam and makes the skin soft, so bake the potato uncovered for a crisp exterior. Foil can be used when a softer skin is preferred, but it changes the texture and may affect the cooking time. Remove foil before storing leftovers and refrigerate promptly.
How can I tell when the potato is done without cutting it open?
Push a thin skewer or small knife into the thickest part. It should glide through the flesh with little resistance. You can also gently squeeze the potato using an oven mitt; it should give slightly, but do not rely on squeezing alone if the center might still be firm. An instant-read thermometer can help: a center around 205–210°F (96–99°C) is a good texture guide.
Can I bake more than one large potato at a time?
Yes. Put them in a single layer with room between each potato for air to move around them. Several potatoes may need extra time, especially if they are large or crowded together, so check each one individually. Choose potatoes of similar size if you want them to finish at about the same time.
Can I prepare the potato ahead?
You can wash and dry it earlier in the day, then refrigerate it uncovered or loosely covered until baking. For the best skin, dry it again if any moisture has collected, then oil and salt it just before it goes into the oven. A fully baked potato can also be refrigerated within 2 hours and reheated later, though the skin will be crispest when freshly baked.
