You’ll usually bake a whole russet potato in the oven for about 45–60 minutes at 400–425°F (200–220°C), until it’s very tender inside and the skin is crisp.

Ideal time and temperature

  • At 400°F (200°C): a medium russet takes about 45–60 minutes.
  • At 425°F (220°C): many recipes give 45–60 minutes for a medium potato with extra‑crispy skin.
  • A potato is done when a fork or thin knife slides in with almost no resistance, or the internal temperature is around 205–210°F.

Size adjustments

  • Small potatoes: about 30–40 minutes at 400–425°F.
  • Large/big steakhouse-style potatoes: 60–75 minutes or more, depending on thickness.

As a rough guide, if you start checking at 45 minutes and then every 5–10 minutes, you’ll almost always land in the perfect zone.

Simple step‑by‑step method

  1. Preheat oven to 400–425°F (200–220°C).
  1. Scrub russet potatoes and dry well.
  1. Prick each potato several times with a fork.
  1. Rub lightly with oil and sprinkle with salt.
  1. Place directly on the oven rack or on a rack over a baking sheet.
  1. Bake 45–60 minutes, checking for tenderness from 45 minutes onward.
  1. When done, let sit a few minutes, then slice, fluff with a fork, and add toppings.

Quick Scoop (mini sections)

For fluffy inside

  • Use starchy russet potatoes rather than waxy types.
  • Aim for that 205–210°F internal temp sweet spot.

For crispy skin

  • Skip wrapping in foil; foil steams the potato and softens the skin.
  • Bake directly on the rack and don’t overcrowd the oven so moisture can escape.

If you’re in a hurry

  • You can par‑cook potatoes in the microwave for 5–8 minutes, then finish in a hot oven for 15–25 minutes to crisp the skin.

Tiny storytelling touch

Imagine tossing a couple of russets straight onto the oven rack before you start making dinner; by the time you’ve sautéed some veggies and set the table, you press a fork into the potato and it gives way like a warm loaf of bread—that’s the texture you’re aiming for.

TL;DR: Bake a medium russet potato at 400–425°F for about 45–60 minutes, until a fork slides in easily or the center reaches around 205–210°F.
