To roast sweet potatoes at 400°F, the typical cooking time ranges from about 25 to 45 minutes depending on the size and cut of the potatoes:
- For sweet potatoes cut into small chunks or quarter-moons about ½ inch thick, roast for 25-30 minutes, flipping halfway through to ensure even crisping
- If cut into 1-inch chunks, roast for about 30-35 minutes, tossing once or twice during cooking until tender and browned
- Whole sweet potatoes halved lengthwise generally take about 40 minutes to become soft and fully cooked
- For medium-sized chunks, roasting for 30-45 minutes until fork tender is common, tossing once halfway through
In summary, roasting sweet potatoes at 400°F usually takes between 25 and 45 minutes depending on the cut size, with smaller pieces cooking faster and whole or halved potatoes taking longer. Tossing or flipping halfway through helps achieve even cooking and crispiness
