In the hierarchy of all the ways to cook a sweet potato, perfectly roasted chunks will forever sit at the top of my list. I’m not talking about a quick flash in a screaming-hot oven when you’re in a hurry to get dinner on the table. I’m talking about those substantially sized cubes with well-browned, caramelized edges that crackle when you bite through the crisp surface and into the creamy center. The kind so impossibly irresistible you can’t help but risk burning your fingertips and tongue to pop a few into your mouth the second the baking sheet comes out of the oven.

Whether you prefer plain roasted sweet potatoes with just a sprinkling of salt or like to give them an extra sweet or savory twist, they’re easy to make once you know the few key steps to success. Here’s how to do it.

How Long to Roast Sweet Potatoes

Roast the sweet potatoes until tender and browned all over, 30 to 35 minutes at 400°F. Be sure to flip them halfway through.

Do You Need to Peel Sweet Potatoes Before Roasting?

Yes! For the best flavor and caramelization, peel the sweet potatoes before roasting.

4 Key Steps to the Best Roasted Sweet Potatoes

1. Cut the potatoes into 1-inch cubes. One-inch cubes are the ideal size when cutting up the peeled potatoes. These bite-sized chunks aren’t too big or too small and work just as well for a side dish as they do as an addition to salads, tacos, grain bowls, and wraps. Also remember that cutting evenly sized pieces ensures they all take the same time to cook.

2. Roast at 400°F. Temperature is an important factor in getting roasted sweet potatoes just right. This temperature is hot enough to deliver the tender, creamy centers and the charred, caramelized surface you expect from sweet potatoes. Setting the dial at 400°F, rather than 425°F or 450°F, means a slightly longer cook time, which helps coax out even more of this spud’s natural sweetness.

3. Use plenty of oil. Don’t be afraid to use plenty of fat when roasting sweet potatoes. A generous slick of olive oil helps give the potatoes those caramelized, crispy edges that makes them so irresistible.

4. Use your hands to coat the potatoes evenly. You’re going to want to make sure all the sweet potato cubes are well-coated with oil, and the best way to get the job done is with your hands. I know it’s a bit messier than using a wooden spoon or rubber spatula, but those tools simply don’t work as well.

How to Make Sweet or Savory Roasted Sweet Potatoes

Roasted sweet potatoes are pretty darn delicious with a simple sprinkling of salt, but should you want something more, these spuds are super versatile and take well to extra flavorings.

  • Sweet: Toss the cubes with a shower of ground cinnamon and add a drizzle of honey halfway through cooking for a sticky-sweet batch of vegetables that taste like candy. While this sweet twist makes a great side dish, try them also as a grain bowl topper, add them to yogurt and oatmeal, or mash them and layer onto a slice of ricotta toast.
  • Savory: If savory is more your speed, the warm, smoky aromas of ground cumin and chili powder are a perfect partner to sweet potatoes. The spiced flavors balance the vegetable’s natural sweetness and add a gentle kick. Simply toss the potatoes with a spoonful of these spices before they go into the oven.

Keep potatoes crisp in a warm oven if you're serving them in 1-2 hours. If there is a slight wait before everyone eats, don't cover the crispy potatoes—this traps steam which will make the potatoes soggy. Just keep them in the oven, but turn the temperature to the lowest setting.

Why are my potatoes not getting crispy in the oven? ›

If roasted potatoes lack their crunchy sheen, overcrowding is usually the culprit. Just as overcrowding bacon or mushrooms in a saucepan causes disappointingly mushy results, placing potatoes too close to each other on a baking sheet will prevent them from crisping while they roast.

Why won't my potatoes get crispy in oil? ›

A: This sure sounds a lot like potatoes that have been stored too long, in too cold of an environment before cooking. When potatoes are held below 41°F for too long a period, the starches convert to sugar and it changes the cooking chemistry.
