The best way to bake a sweet potato
Scrub a sweet potato, pierce its skin with a fork, and bake on a tray at 400°F for about 45–60 minutes, until the center offers little resistance. Use the microwave alternative for one potato when time is short.

Choose similarly sized potatoes when cooking more than one. A large thick sweet potato can stay firm long after a smaller one softens, so treat time as a planning range. The microwave produces a different skin texture; use the oven when the roasted exterior matters.

Before you start
- Scrub the skin before piercing or cutting.
- Pierce several places so steam can escape.
- Handle with mitts and open carefully; the interior is very hot.
Whole oven bake method
Prepare the potato
Scrub and dry. Pierce the skin 5–6 times with a fork.
Look for Clean intact skin with small vent holes.
Heat the oven
Preheat to 400°F and place the potato on a rimmed tray.
Look for A tray positioned to catch drips.
Bake until soft
Begin checking around 45 minutes and continue as needed, often to 60 minutes.
Look for A fork enters the thick center easily.
Split carefully
Let it settle briefly, then split lengthwise and fluff the interior. Add topping after checking a small bite’s temperature.
Look for Soft flesh without a firm center.
Fix common problems
Ending the cook at a fixed minute even though the center is still firm.
Center hard? Continue cooking and recheck the thickest point.
Syrupy drips burning? Use a rimmed tray in the oven; clean only after cooling.
Common questions about this method
Can I cook several together?
Use similar sizes and test each potato separately. Microwave timing for one potato does not automatically scale to several.
