Potatoes in the oven turn out perfectly when you match the temperature to the variety and the texture you’re after. So if you’re wondering what temperature to cook potatoes at in the oven, the honest answer is that it depends on the potato and the result you want. Russets like it hot. Waxy potatoes prefer it a bit lower. Below you’ll find exact numbers, times, and simple steps for every common style.
This guide covers roasted wedges, whole baked potatoes, baby potatoes, fries, and more. Pick your potato type, set your oven, and follow the chart.
What Temperature To Cook Potatoes At In The Oven
Most potatoes cook best between 400°F and 425°F (200°C to 220°C). That range gives you a crisp outside and a fluffy inside. But the right number changes based on what you’re making. Use this quick guide.
- Roasted wedges and chunks: 425°F (220°C)
- Whole baked potatoes: 400°F (200°C)
- Baby potatoes: 400°F (200°C)
- Fries (oven): 425°F (220°C)
- Potato slices or rounds: 400°F (200°C)
- Twice baked potatoes: 400°F (200°C) for the first bake
If you only remember one number, make it 425°F. It works for almost everything except whole potatoes, which need a bit more time at a slightly lower heat.
Why Temperature Matters So Much
Potatoes are mostly water and starch. Heat does two things at once. It drives out moisture and it browns the surface. Too low, and the potato steams instead of roasting. Too high, and the outside burns before the middle cooks.
Starch also behaves differently at different heats. Around 400°F, starch granules swell and soften, which gives you that fluffy center. Above 425°F, sugars on the surface caramelize fast. That’s what makes a good crust.
Best Temperature By Potato Variety
Russet Potatoes
Russets are high in starch and low in moisture. They’re ideal for baking and for crispy roasted chunks. Bake whole russets at 400°F for 60 to 70 minutes. Roast cut russets at 425°F for 35 to 45 minutes.
Yukon Gold Potatoes
Yukon Golds sit in the middle. They’re creamy but hold their shape. Roast them at 400°F for 30 to 40 minutes. They brown nicely without drying out.
Red Potatoes
Red potatoes are waxy and firm. They keep their shape, so they work well for slices and wedges. Roast at 400°F for 30 to 35 minutes. Whole baby reds need about 25 minutes.
Fingerling Potatoes
Fingerlings are small and waxy. Roast them whole at 400°F for 25 to 30 minutes. Cut them in half for faster cooking, around 20 minutes.
Step-By-Step: How To Roast Potatoes At The Right Temperature
- Heat your oven to 425°F (220°C). Let it fully preheat, about 15 minutes.
- Wash and cut your potatoes into even 1-inch pieces. Even size means even cooking.
- Dry them well with a towel. Wet potatoes steam and never crisp.
- Toss with oil, salt, and pepper. Use about 1 tablespoon of oil per pound.
- Spread them in a single layer on a sheet pan. No crowding.
- Roast for 20 minutes, then flip with a spatula.
- Roast another 15 to 25 minutes until golden and fork tender.
Total time is usually 35 to 45 minutes at 425°F. Smaller pieces cook faster. Larger wedges take longer.
How To Bake A Whole Potato
- Set the oven to 400°F (200°C).
- Scrub the potato and poke it 5 or 6 times with a fork.
- Rub the skin with a little oil and salt.
- Place it directly on the middle rack, or on a baking sheet.
- Bake for 60 to 70 minutes for a large russet.
- Check with a knife. It should slide in with no resistance.
A 10-ounce potato takes about an hour. Smaller ones take 45 to 50 minutes. If you’re short on time, raise the heat to 425°F and cut the time to about 45 minutes. The skin gets crisper that way.
Temperature For Oven Fries
Fries need high heat. Set the oven to 425°F (220°C). Cut potatoes into thin sticks, soak them in cold water for 30 minutes, then dry them fully. Toss with oil and spread on a pan. Bake for 20 minutes, flip, then bake 15 to 20 more minutes.
Some cooks go as high as 450°F (230°C) for fries. That works if your oven runs accurate. Watch them closely so they don’t burn.
Convection Vs Regular Oven
A convection oven moves air around, so food cooks faster and browner. If you use convection, drop the temperature by 25°F. So 425°F becomes 400°F. Check your potatoes 5 to 10 minutes early the first time.
Common Mistakes To Avoid
- Not preheating. A cold oven gives you pale, soft potatoes.
- Crowding the pan. Trapped steam stops browning.
- Using too little oil. Oil carries heat and helps the crust form.
- Cutting pieces uneven. Small bits burn while big ones stay raw.
- Salting only at the end. Salt early for better flavor.
- Opening the oven too often. Heat escapes and cooking slows down.

- Wedges: 425°F, 30 to 40 minutes
- Baby potatoes: 400°F, 25 to 30 minutes
- Slices and rounds: 400°F, 25 to 35 minutes
- Oven fries: 425°F, 35 to 40 minutes

How To Tell When Potatoes Are Done
Color is your first clue. The edges should be deep golden brown. Next, test with a fork or knife. It should slide in easily with no firm center. If the outside looks done but the inside feels hard, lower the heat to 375°F and give it 10 more minutes.
For whole baked potatoes, squeeze gently with a towel. A done potato gives slightly under pressure. If it feels rock hard, keep baking.
Storing And Reheating
Keep leftovers in a sealed container in the fridge for up to 4 days. Reheat at 400°F for 8 to 10 minutes. A microwave works too, but the texture gets softer. For the best results, reheat in the oven on a sheet pan.
Now you know exactly what temperature to cook potatoes at in the oven for any style. Match the heat to the potato, keep your pieces even, and don’t crowd the pan. That’s all it takes for a crisp, golden result every time.
