For a classic oven-baked potato, plan on about 45–60 minutes at 400–425°F (200–220°C) for a medium russet potato, and up to 75–90 minutes for very large ones, until the inside is completely tender when pierced with a fork and the skin is crisp.

How long should I bake a potato?

Here’s a simple timing guide for whole, unwrapped russet potatoes in a conventional oven:

  • Small potatoes (about 5–6 oz): 35–45 minutes at 425°F (220°C).
  • Medium potatoes (about 8 oz): 45–60 minutes at 400–425°F (200–220°C).
  • Large/extra-large potatoes (10–14 oz): 60–90 minutes at 400°F (200°C).

Doneness checks:

  • A fork or skewer should slide in with almost no resistance.
  • Internal temperature should be around 205–210°F (96–99°C) in the center for fluffy insides.

Basic step‑by‑step method

  1. Preheat the oven
    • Set to 400–425°F (200–220°C). Many modern recipes like 425°F for crispier skin.
  1. Prep the potatoes
    • Scrub and dry russet potatoes.
 * Prick each potato a few times with a fork to vent steam.

 * Rub lightly with oil and sprinkle with coarse salt for a crisp, flavorful skin.
  1. Bake
    • Place directly on the oven rack or on a baking sheet.
 * Bake using the time guide above, starting to check around 40–45 minutes for medium potatoes.
  1. Test and finish
    • Pierce with a fork or gently squeeze with an oven mitt; it should feel soft and “give” easily.
 * If still firm, continue baking in 5–10 minute increments.
  1. Serve
    • Let sit a minute or two, then slice open, fluff with a fork, and add toppings (butter, sour cream, cheese, chives, etc.).

Time and temperature variations

Different cooks like slightly different setups; here are common “formulas”:

  • 425°F (220°C), 45–60 min – Very popular for crisp skin and fluffy interior for medium potatoes.
  • 400°F (200°C), 50–70 min – A bit gentler, good if you’re baking other dishes at 400°F.
  • Two‑stage bake (popular blog method) :
    • First 25 minutes at about 450°F (230°C), then brush with butter or oil and bake about 20 more minutes, checking and extending in 5‑minute increments as needed (total ~45–55 min).

Use these as starting points, then rely on tenderness and temperature for precision.

Method Typical Time Texture Result Notes
Oven, 425°F, whole 45–60 min (medium) Fluffy inside, crisp skin Most traditional and reliable approach.
Oven, 400°F, whole 50–70 min Very fluffy, slightly gentler bake Good when sharing the oven with other dishes.
Two‑stage high‑heat bake About 45–55 min total Extra crisp skin, soft interior Uses a mid‑bake oil/butter brushing step.
Microwave then oven finish 5–10 min microwave + 10–15 min oven Very fast, skin less evenly crisp Common home shortcut (varies by microwave; general forum advice).

Little story-style tip

Think of your potato like a tiny, edible “baking thermometer.” At first it feels heavy and solid; as it bakes, the inside turns steamy and light. When you press it with an oven mitt and it yields like a soft stress ball and your fork glides in with no pushback, that’s your signal that it’s ready—no stopwatch required.

TL;DR: For a medium russet, bake at 425°F (220°C) for about 45–60 minutes , and trust the fork test or a 205–210°F internal temp more than the clock.
