how long to cook small potatoes in oven
For small whole baby potatoes, a reliable range is 25–35 minutes in a hot oven, depending on size and temperature.
Quick Scoop
- At 400°F (200°C): about 20–30 minutes for small baby or “little yellow” potatoes.
- At 425°F (220°C): about 20–30 minutes, often around the 25–30 minute mark for halved baby potatoes.
- Smaller = faster: tiny potatoes or halved ones tend to be ready closer to 20 minutes; slightly larger “small” potatoes can push toward 30–35 minutes.
- Doneness test: poke with the tip of a knife or fork; if it slides in easily and the potatoes are golden at the edges, they’re done.
Ideal Basic Method
- Preheat oven to 400–425°F (200–220°C).
- Wash and dry small potatoes; leave whole if marble-sized, or cut in half if golf-ball-sized.
- Toss with olive oil, salt, pepper, and any herbs or spices you like.
- Spread in a single layer on a baking sheet, cut side down if halved for extra crispiness.
- Roast 20 minutes, then check: shake the pan or flip them, and continue roasting 5–15 minutes more until tender and golden.
Think of 20 minutes as your first check , not the finish line—ovens and potato size vary a lot.
Time Guide by Size (Small Potatoes)
| Potato size / prep | Oven temp | Approx. time | Notes |
|---|---|---|---|
| Very small baby, whole | 400°F / 200°C | 20–25 min | Check at 20 min; knife should slide in easily. | [1][7][9]
| Small baby, halved | 400°F / 200°C | 20–30 min | Cuts expose more surface, so edges crisp faster. | [5][7][9][3]
| Small baby, halved | 425°F / 220°C | 25–30 min | Common choice for extra crisp exteriors. | [7][3][5]
| With a roast in same pan | ~350°F / 175°C | 1–1¼ hours | Lower heat means longer time; potatoes end up very soft and crisped. | [1]
Little Story-Style Example
You toss a bowl of tiny gold potatoes with olive oil, salt, pepper, and a bit of garlic, then slide the tray into a 425°F oven while you prep the rest of dinner. At the 20-minute mark, you open the door to give them a shake; they’re starting to brown, but the knife test still meets a bit of resistance. Another 8–10 minutes later, they’re deeply golden on the flat sides, the knife glides right through, and the centers are fluffy enough that a little crack opens when you press one with a fork.
Quick Tips for Best Results
- Use a hot, preheated sheet pan for extra crisp bottoms.
- Do not crowd the pan; give each potato some space so they roast instead of steam.
- For extra flavor, toss with fresh herbs or minced garlic right after roasting while they’re still sizzling.
TL;DR: For “small potatoes in oven,” aim for about 25–30 minutes at 400–425°F, checking first at 20 minutes and using a knife test to confirm tenderness.
