How Long Does It Take to Bake a Potato?

Quick Answer

A baked potato takes 45–60 minutes in a conventional oven at 400°F (200°C). The microwave method takes just 5–8 minutes, while the air fryer splits the difference at 35–40 minutes.

Baking Times by Method

• Conventional oven (400°F): 45–60 minutes
• Convection oven (375°F): 40–50 minutes
• Air fryer (400°F): 35–40 minutes
• Microwave: 5–8 minutes
• Grill (medium-high heat): 45–60 minutes
• Instant Pot/pressure cooker: 12–15 minutes

Oven Method (Best Results)

1. Preheat oven to 400°F (200°C)
2. Scrub potatoes clean and dry them
3. Pierce each potato 6–8 times with a fork
4. Rub with olive oil and sprinkle with salt (optional but recommended)
5. Place directly on the oven rack or on a baking sheet
6. Bake 45–60 minutes until a fork slides in easily
7. Let rest 5 minutes before cutting open

Factors That Affect Baking Time

Potato size is the biggest variable. Small potatoes (5–6 oz) take about 45 minutes. Large russets (10–12 oz) need a full 60 minutes or slightly more.

Potato variety matters. Russet (Idaho) potatoes are the classic choice — they bake up fluffy inside. Yukon Gold and red potatoes hold more moisture and have a different texture.

Wrapping in foil steams the potato rather than truly baking it. Skip the foil for a crispier skin and fluffier interior.

Starting temperature — potatoes straight from the fridge take a few extra minutes compared to room temperature.

Altitude — at higher elevations, you may need to increase baking time slightly.

How to Tell When It’s Done

• A fork or knife slides into the center with no resistance
• The potato gives slightly when squeezed (use an oven mitt)
• Internal temperature reaches 205–210°F

Best Microwave Method

For when you’re in a hurry:

1. Pierce potato all over with a fork
2. Microwave on high for 5 minutes
3. Flip and microwave 2–3 more minutes
4. Let rest 2 minutes

The microwave method is fast but produces softer skin. For the best of both worlds, microwave for 4 minutes then finish in a 400°F oven for 15–20 minutes.

Tips

• Don’t skip piercing — unpierced potatoes can explode from steam buildup
• Oil and salt the skin for a crispier, more flavorful exterior
• Bake extra — leftover baked potatoes make great home fries or potato soup
• Fluff with a fork after cutting open to let steam escape
