Baked Potato in Foil Recipe
Wrapping the potato in foil traps steam against the skin as it bakes, which softens the skin and speeds cooking, while the interior still bakes through to a dry, fluffy texture as long as the potatoes are pierced first to let steam escape from the inside too.

Instructions
- 1Preheat the oven to 425°F (220°C).
- 2Scrub the potatoes under cold water and dry them thoroughly with a towel.
- 3Pierce each potato 6-8 times with a fork, spacing the holes evenly around the potato.
- 4Rub each potato all over with olive oil, then sprinkle with kosher salt.
- 5Wrap each potato tightly in a sheet of aluminum foil, twisting the ends closed.
- 6Place the wrapped potatoes directly on the oven rack or on a baking sheet and bake for 55-65 minutes, until a knife slides into the center with no resistance.
- 7Carefully unwrap the potatoes (steam will escape), then slice a lengthwise cut down the top of each one and squeeze the ends toward the center to open it up.
- 8Fluff the interior with a fork and top with butter, sour cream, and chives.
Tips & variations
- For a firmer, less steamed skin, skip the foil entirely and bake the oiled, salted potatoes directly on the rack; foil is purely a texture and convenience choice, not a food safety requirement.
- Russets are the standard choice because their high starch, low moisture flesh bakes up fluffy; waxy potatoes like red or fingerling stay dense and gummy no matter how long they bake.
- Size the potatoes evenly so they all finish around the same time; a potato twice the size of another can need 15-20 extra minutes.
- Try loaded-potato toppings like shredded cheddar, crumbled bacon, and sliced scallions in place of the sour cream and chives.
Storage & reheating
Let leftover baked potatoes cool completely, then wrap individually in foil or plastic and refrigerate for up to 4 days. Reheat unwrapped on a baking sheet in a 400°F (200°C) oven for 15-20 minutes, or microwave for 2-3 minutes, until heated through. Baked potatoes don't freeze well; the texture turns watery and grainy once thawed.
Tips from the Tulo kitchen
- A metal skewer inserted through the center before baking conducts heat into the middle of the potato and can shave 10-15 minutes off the total bake time.
- Rubbing the potato with oil before wrapping keeps the foil from sticking to the skin once it's baked.
FAQ
Do I need to wrap a baked potato in foil?
No, foil is optional. It steams the skin soft and holds in heat for easier handling, but an unwrapped potato baked directly on the oven rack develops a drier, crisper skin in the same amount of time.
Why is my foil-wrapped potato still hard in the middle?
It likely needs more time or the potato was oversized; a typical 8-ounce russet needs 55-65 minutes at 425°F (220°C), but potatoes larger than that can take 75-90 minutes.
Is it safe to leave a foil-wrapped baked potato out at room temperature?
No. Foil-wrapped baked potatoes held warm at room temperature for more than 2 hours can support the growth of Clostridium botulinum in the low-oxygen environment under the foil; refrigerate leftovers promptly instead of leaving them wrapped on the counter.
Can I bake potatoes in foil ahead of time and reheat them?
Yes. Bake them fully, cool, and refrigerate wrapped for up to 4 days, then reheat unwrapped in a 400°F (200°C) oven for 15-20 minutes so the skin doesn't turn soggy.
