If your roasted sweet potatoes always come out soft instead of crispy, this recipe will change that. I bake mine at 425°F, cut them into uniform ½-inch cubes, and give them plenty of space on the pan, that’s the key to getting those caramelized, golden edges every time. Smoked paprika and garlic powder do the rest of the work, and the whole thing is ready in 45 minutes.
Why I Love Roasted Sweet Potatoes
Sweet potatoes are genuinely one of my favorite ingredients to cook with. I’ve been making them in every way imaginable for years.
I make sweet potato fries, air fryer baked sweet potatoes, and I love adding them to heartier dishes like this Ground Turkey Sweet Potato Skillet. They’re endlessly versatile. You can have them for breakfast, lunch, or dinner and they never get old.
But roasted sweet potatoes are the version I come back to most. There’s something about that crispy, caramelized outside and soft, fluffy inside that makes them irresistible straight off the pan.
I serve them alongside air fryer salmon, baked chicken thighs or garlic butter baked chicken breast for a quick weeknight dinner, toss them into cottage cheese taco bowls, or add them to a green salad with a light vinaigrette.
Key Ingredients:
Sweet potatoes — I use 2 medium sweet potatoes, about 1 pound total. Look for firm ones with smooth skin and no soft spots. I prefer the orange-fleshed variety (sometimes labeled Jewel or Garnet). They’re naturally sweeter and give you that beautiful caramelized color when roasted.
Olive oil — This is what helps the outside of the potatoes get golden and crispy in the oven. I use 2 tablespoons, which is just enough to coat every piece without making them greasy. Avocado oil works great too if that’s what you have on hand.
Smoked paprika — This is my favorite spice for roasted sweet potatoes. It adds a subtle smoky depth that balances the natural sweetness of the potato beautifully. I always reach for smoked over regular paprika here, the difference in flavor is noticeable.
Garlic powder — I love how garlic powder coats every cube evenly and roasts right into the potato, giving you that savory flavor in every bite. Fresh garlic tends to burn at high heat, so garlic powder is the better choice for this recipe.
Salt and black pepper — Simple but essential. Salt draws out the moisture and helps with caramelization, while freshly cracked black pepper adds a little warmth.
How to cut a sweet potato for roasting
The way you cut your sweet potatoes makes a real difference in how they roast. I’ve tested a few different methods over the years, and this is the one I always come back to for the best results.
1. Start by peeling the sweet potato, then slice it into rounds about ½ inch thick. From there, cut each round into cubes. I aim for ½-inch pieces so everything is roughly the same size.
Note: Uniform pieces are key here. If some are bigger than others, the smaller ones will burn before the larger ones are cooked through.
2. This is what you’re going for. Uniform ½-inch cubes, ready to season and roast. At this size, they get beautifully crispy on the outside while staying soft and fluffy on the inside.
How to make roasted sweet potato
Preheat your oven to 425°F. High heat is essential here — it’s what gives the potatoes those crispy, caramelized edges. A lower temperature will cook them through, but you won’t get that golden exterior.
Mix your spice blend. Add the smoked paprika, garlic powder, salt, and black pepper to a small bowl and whisk them together before they go on the potatoes. This takes 30 seconds and makes sure every cube gets evenly seasoned.
Season the potatoes on the baking sheet. Spread the cubed sweet potatoes on a large baking sheet, drizzle with olive oil, then sprinkle the spice mixture over the top.
Toss with your hands. I always use my hands for this step — it’s the best way to make sure every single piece is coated in oil and seasoning all the way around.
Spread them in a single layer with space between each piece. This is the most important step for crispy roasted sweet potatoes. If the cubes are touching or overlapping, they’ll trap steam and end up soft instead of roasted. If your baking sheet feels crowded, use two pans.
Roast for 35 minutes, flipping every 10 minutes. Flipping them regularly ensures all sides get direct contact with the hot pan, so you get even browning all the way around, not just on the bottom.
Olivia’s Best Recipe Tips
You don’t have to peel them. This is completely personal preference. I usually peel mine because I prefer the texture, but the skin is totally edible and actually gets a little crispy in the oven, which a lot of people love. If you leave the skin on, just make sure to scrub the potatoes well under cold water and dry them thoroughly before cutting.
Dry the potatoes before seasoning. If you’ve just washed and peeled your sweet potatoes, pat them dry with a paper towel before adding the oil. Excess moisture creates steam in the oven, which works against you when you want crispy edges.
Taste and adjust the seasoning. I’ve given you the quantities I love, but every oven is a little different and so is every palate. Feel free to add a pinch more paprika for extra smokiness, or a little cayenne if you want some heat. Thomas loves a tiny bit of cinnamon mixed in. It brings out the natural sweetness of the potato beautifully.

Never thought to combine sweet potatoes and cashews but this sounds good. I would think the cashews would burn before the potatoes were done though.
This combo works very well. You will like it 😉
Hi Olivia,
I made this for dinner and it was a lovely combination. I think just a hint of cinnamon would be a nice addition. I was really afraid the cashews would burn, so I roasted them in a different pan. They took only about 10 minutes. Thanks for the recipe!
I am so glad it turned out well. Thanks for letting me know 😉
Omg I am in loveeee with your blog! You have such great taste – really similar to mine. I also posted a recipe for sweet potato and nuts, although I used hazlenuts and added goats cheese. I am going crazy over all of your recipes! Added to blogroll! 🙂
Thanks you so much for your compliment! Glad you like my blog!I visited your blog and I love too 😉
Thanks for stopping by!
Um yummy. I love sweet potatoes. Will give this a try. Thank you.
Thank you I love seasoning on my sweet potatoes. This recipe is a keeper. Thanks again.
You’re very welcome!
Do you have air fryer directions?
Yes. Just air fry the seasoned sweet potato cubes at 400°F for 15–18 minutes, shaking halfway, until tender and crisp.
