what temp to cook sweet potatoes in the oven

For classic baked whole sweet potatoes, a good target is 400°F (about 200°C) for 45–60 minutes, until they’re very soft when pierced with a fork.

Quick Scoop

• Whole sweet potatoes:
  • Most home cooks and recipes use 400°F as the “sweet spot” for fluffy, creamy insides and lightly crisp skin.

* Bake about 45–60 minutes depending on size; larger ones can take closer to an hour.

• Hotter and faster:
  • For cubes or wedges, 425°F is common, roasting around 30–35 minutes until browned and tender.

• Even hotter (very caramelized):
  • Some methods go up to 450°F for extra caramelization, but you need to watch closely so they don’t burn.

Simple whole-baked method

1. Preheat oven to 400°F (200°C).

2. Scrub potatoes clean and dry them well.

3. Pierce each several times with a fork so steam can escape.

4. (Optional) Rub with a little oil and sprinkle with salt for nicer skin.

5. Place on a foil- or parchment-lined tray.
6. Bake 45–60 minutes, until a fork or knife slides in with almost no resistance.

Rule of thumb:

• Whole, uncut: 400°F, 45–60 minutes.
• Cut into chunks: 425°F, about 30 minutes.

TL;DR: If you’re wondering what temp to cook sweet potatoes in the oven and don’t want to overthink it, set the oven to 400°F and bake until they’re very soft inside.
