what temp to bake sweet potatoes in oven
Bake whole sweet potatoes in a hot oven: 400–425°F (200–220°C) is the sweet spot for fluffy insides and caramelized sweetness.
Best temperature and timing
- For classic whole baked sweet potatoes, most modern recipes use 425°F / 220°C.
- Many home cooks also use 400°F / 200°C with excellent results, especially if they want a slightly gentler bake.
- At these temps, medium potatoes usually take 40–60 minutes , depending on size and oven accuracy.
Think of it this way: hotter (425°F) = a bit more caramelized and faster; slightly lower (400°F) = gentler, a touch longer, still great.
Simple step‑by‑step (whole potatoes)
- Preheat oven to 425°F (220°C) and line a baking sheet with foil or parchment.
- Scrub and dry the sweet potatoes; leave skins on.
- Prick each potato several times with a fork or make shallow slashes to release steam.
- Rub lightly with oil and a little salt if you like, then place on the tray.
- Bake 40–50 minutes at 425°F (or 45–60 minutes at 400°F), until a fork slides in easily and the skins look puffed.
- Rest 5 minutes, split open, and add toppings (butter, salt, cinnamon, etc.).
Quick rule of thumb: if they’re big and fat, go closer to 60 minutes; if they’re small and slim, start checking around 35–40 minutes.
Diced or halved sweet potatoes
If you’re not baking them whole, the temp is similar but time drops.
- Diced/cubed :
- Temperature: 400°F (200°C).
* Time: about **30–40 minutes** , stirring every 15 minutes, until edges are browned and the pieces mash easily with a fork.
- Halved lengthwise :
- Temperature: 400°F.
* Time: about **20–30 minutes** , cut side down, until soft all the way through.

| Prep style | Oven temp | Approx. time | Notes |
|---|---|---|---|
| Whole sweet potatoes | 425°F / 220°C | 40–50 min | Fluffy inside, nice caramelization; very common in recent recipes. | [5][1][3]
| Whole sweet potatoes | 400°F / 200°C | 45–60 min | Gentler, widely used by home cooks and video guides. | [2][9][7]
| Diced / cubed | 400°F / 200°C | 30–40 min | Stir during baking; great for meal prep or bowls. | [10][7]
| Halved lengthwise | 400°F / 200°C | 20–30 min | Cut side down; faster than whole. | [7]
Little storytelling-style tip
Imagine tossing a few scrubbed sweet potatoes on a tray before you start cooking dinner: by the time you’ve cleaned up the kitchen, they’re puffed, tender, and smell like roasted sugar. You slice one open, steam rushes out, a pat of butter melts into the orange flesh, and suddenly that “simple side” feels like the main event. That’s exactly what 400–425°F in the oven does for them—minimal effort, big cozy payoff.
TL;DR: Bake whole sweet potatoes at 400–425°F (200–220°C) until a fork slides in easily—usually 40–60 minutes , depending on size and exact temp.
