At 350°F (177°C), whole russet potatoes usually take about 60–75 minutes to bake until fluffy inside and crisp outside, depending mainly on size.

Quick Scoop

  • Small potatoes (about 4–5 oz): 50–60 minutes.
  • Medium potatoes (about 5–7 oz): around 60 minutes.
  • Large baking potatoes (8–12 oz): 70–80 minutes.
  • They are done when:
    • A fork slides in with almost no resistance, and the potato feels very soft when gently squeezed with an oven mitt.
* The skin is dry and crisp, and the inside has reached about 210°F if you check with a thermometer.

Simple step‑by‑step

  1. Preheat oven to 350°F.
  1. Scrub potatoes and dry well.
  1. Prick each potato 4–6 times with a fork so steam can escape.
  2. Rub lightly with oil and sprinkle with salt if you like crispy, flavorful skin.
  1. Place directly on the oven rack or on a baking sheet.
  2. Bake 60 minutes, then start checking every 5–10 minutes until very soft (most are perfect between 60 and 75 minutes).

If you’re in a hurry, baking at a higher temp like 400–425°F cuts the time but 350°F tends to give a very evenly cooked, fluffy potato.

Mini Q&A

  • Q: Can I wrap them in foil at 350°F?
    A: Yes, but the skin will be soft, not crisp, and the potatoes may cook a bit faster because steam is trapped inside.

  • Q: What if they’re not done at 60 minutes?
    A: Just keep going in 10‑minute increments until the fork test says they’re soft; size and oven accuracy make a big difference.
