Oven-Roasted Sweet Potatoes

Jump to Recipe

There’s something especially good about a pan of sweet potatoes fresh from the oven.
The little cubes come out deeply golden around the edges, soft in the middle,
and sweet enough that it’s hard not to pick a few straight from the sheet pan.

This is the kind of side dish I come back to when I want something simple that goes with almost anything.
You can keep the sweet potatoes lightly sweet with coconut oil and brown sugar,
or give them a savory spin with chili powder, paprika, cumin, and garlic.

Either way, the real magic happens in the oven, where high heat turns those edges beautifully
caramelized while the centers become tender and creamy.

Why You’ll Love This Recipe

For me, the best part of roasted sweet potatoes is always those browned edges. Cutting the potatoes into small 1/2-inch pieces gives them lots of surface area to caramelize, while the insides stay wonderfully soft.

I also love that this recipe gives you two ways to make them. The plain version brings out the natural sweetness of the potatoes with coconut oil, brown sugar, and sea salt. The seasoned version goes in a warmer, savory direction with olive oil, chili powder, paprika, cumin, and garlic powder.

Both are easy, unfussy, and endlessly useful. Serve them straight from the sheet pan with dinner, or tuck them into salads, grain bowls, tacos, and burrito bowls throughout the week.

Roasted Sweet Potatoes Ingredients

For Plain Roasted Sweet Potatoes

Sweet Potatoes – The star of the recipe! Red Garnet or Jewel sweet potatoes are especially good here because they roast up soft and creamy inside with beautifully caramelized edges. Peel and cut them into 1/2-inch pieces so they cook evenly.
Coconut Oil – Helps the sweet potatoes brown and gives the plain version a subtle richness. Melt it before tossing it with the potatoes.
Fine Sea Salt – A little salt brings out the natural sweetness of the potatoes. If you’re using table salt instead, use a bit less.
Light Brown Sugar – Adds just enough sweetness to encourage those delicious caramelized edges. Make sure to firmly pack it when measuring.

For Seasoned Roasted Sweet Potatoes

Sweet Potatoes – Cut the peeled potatoes into even 1/2-inch pieces. Keeping them about the same size helps them roast evenly and gives you that lovely tender-inside, browned-outside texture.
Olive Oil – Coats the potatoes and helps the seasonings stick while encouraging the edges to brown in the oven.
Fine Sea Salt – Enhances both the sweetness of the potatoes and the savory spices. Use less if substituting table salt.
Pepper – Adds a gentle peppery bite that balances the natural sweetness of the potatoes.
Chili Powder – Brings warm, savory flavor with a little heat. Chipotle chili powder can be used when you want a smokier taste.
Paprika – Adds another layer of warm flavor. Smoked paprika is also an option if you prefer a deeper, smoky finish.
Ground Cumin – Gives the seasoning blend an earthy warmth that pairs especially well with sweet potatoes.
Garlic Powder – Rounds everything out with savory garlic flavor and distributes easily over all those little sweet potato cubes.

Step-by-Step Instructions

Plain Roasted Sweet Potatoes

Preheat the oven to 425°F.

Peel the sweet potatoes and cut them into 1/2-inch cubes. Place the pieces on your largest sheet pan, then add the melted coconut oil, salt, and brown sugar.

Toss until the sweet potatoes are evenly coated. Arrange them in a single, even layer, making sure the pieces do not overlap. Leaving room between the potatoes allows them to roast rather than steam.

Roast for 27–35 minutes total, flipping the sweet potatoes every 10–15 minutes so they cook and brown evenly. Flipping about every 10 minutes and roasting for approximately 30 minutes works well.

Seasoned Roasted Sweet Potatoes

Preheat the oven to 425°F.

Peel the sweet potatoes and cut them into 1/2-inch cubes. Transfer them to your largest sheet pan. Add the olive oil, salt, pepper, chili powder, paprika, cumin, and garlic powder.

Toss thoroughly so the oil and seasonings coat all of the sweet potato pieces. Spread the potatoes into one even layer without overlapping them; overcrowding can cause them to steam instead of roast.

Roast for 27–35 minutes, turning the sweet potatoes every 10–15 minutes for even cooking and browning. Flipping them roughly every 10 minutes and cooking for around 30 minutes is a good guideline.

Expert Tips

Give them some space. This is probably the most important tip for getting those delicious caramelized edges. Spread the sweet potatoes across a large sheet pan so the pieces aren’t piled on top of one another. When they’re crowded together, they hold onto moisture and steam instead of roast.

Keep the pieces small and even. Aim for 1/2-inch cubes. They don’t have to be perfectly identical, but similarly sized pieces will cook at roughly the same rate.

Don’t forget to flip. Every 10–15 minutes, give the potatoes a turn. It helps different sides make contact with the hot pan and gives you more of those browned, flavorful edges.

Watch the potatoes, not just the clock. Depending on your oven and the variety of sweet potato you use, they may finish a little sooner or later. Once they’re tender inside with nicely caramelized edges, they’re ready.

Recipe Variations

If you love smoky flavors, use chipotle chili powder and/or smoked paprika in the seasoned version. They pair especially nicely with the sweetness of the potatoes.

Want some extra heat? Add 1/4 to 1/2 teaspoon cayenne pepper.

You can also choose between the two versions depending on the rest of your meal. I like the plain sweet potatoes when they’re going into another flavorful dish, where their simple sweetness can complement everything else. The seasoned version is lovely on its own when you want the sweet potatoes to have a little more personality.

Storage & Reheating

These sweet potatoes are great to have waiting in the fridge. Store any leftovers in an airtight container for up to 4 days.

When you’re ready to eat them again, I recommend reheating them in the oven or air fryer. They’ll warm through while getting some of those crisp edges back.

Serving Suggestions

You could easily serve these sweet potatoes straight from the sheet pan alongside your favorite protein and call dinner done. They’re especially good with roasted or grilled chicken, fish, turkey, pork, or a simple vegetarian main.

But don’t stop at side dishes! I love roasted sweet potatoes in a hearty grain bowl with quinoa or rice, black beans, greens, avocado, and a flavorful dressing. They’re also delicious tucked into vegetarian tacos or added to burrito bowls and salads.

And if you’ve made a batch for the week, you’re already halfway to an easy lunch. Add the leftover sweet potatoes to whatever greens, grains, beans, or vegetables you have on hand, drizzle everything with your favorite dressing, and dig in.

Recipe FAQs

1. How do I get roasted sweet potatoes crispy instead of soft?
Give the sweet potatoes plenty of room on the sheet pan. Spread them into a single layer without overlapping. If the pan is too crowded, the potatoes will steam instead of roast, and you’ll miss out on those delicious golden, caramelized edges.

2. Do I need to peel the sweet potatoes first?
Yes, I recommend peeling them for this recipe. It gives the roasted sweet potatoes a softer, creamier texture and helps the outside caramelize nicely as they cook.

3. Why should I cut the sweet potatoes into 1/2-inch cubes?
Keeping the pieces around 1/2 inch helps them cook quickly and evenly. Try to make the cubes about the same size so you don’t end up with some pieces that are perfectly tender while others are still firm.

4. How do I know when the sweet potatoes are done?
They’re ready when the centers are tender and the edges are nicely browned and caramelized. They usually take 27–35 minutes at 425°F. Make sure to flip them every 10–15 minutes so they brown evenly.

5. Should I make the plain or seasoned roasted sweet potatoes?
Both are delicious! I like the plain version when adding the potatoes to salads, bowls, or other recipes because their natural sweetness really comes through. The seasoned version is perfect as a side dish when you want a little more flavor from the chili powder, paprika, cumin, and garlic.

Oven-Roasted Sweet Potatoes

Golden around the edges and tender in the center, these roasted sweet potatoes make an easy, versatile side dish. Choose the simple brown-sugar version for a touch of sweetness, or use the savory seasoning blend for a warmer, spiced finish.
