Crispy sweet potatoes are one of those simple oven sides that never let me down: sliced sweet potato rounds roasted until the edges turn deep golden and the centers stay soft and tender. The trick is starting the pan in a cold oven, which lets the inside soften gently before the outside ever gets a chance to dry out. A quick flip partway through gives both sides room to caramelize, and a light sprinkle of brown sugar at the end takes them from good to genuinely craveable.
When I first learned how to make truly crispy roasted sweet potatoes, it was for a small Sunday lunch after church. A few friends were stopping by, and I needed a simple side that felt special without keeping me in the kitchen. These crispy roasted sweet potatoes came out of the oven with caramelized edges and soft centers, and they were the first serving tray on the table to be empty.
Main Ingredients Needed For Crispy Sweet Potatoes
Here’s a quick overview of the key ingredients for this recipe. For the full list of ingredients and exact measurements, jump to the recipe card.
- Sweet potatoes: This is the whole show, so pick nice medium-sized ones with smooth skin. They’re the easiest to peel and slice into even rings. I’ve made this with orange, Garnet, Diane, and Burgundy sweet potatoes, and every one of them roasted up crisp and golden. If you end up with extra, they’re also great in my sweet potato cornbread.
- Olive oil: Helps the edges brown and gives you that glossy coating before they hit the oven. Avocado oil works just as well if that’s what you have on hand.
- Brown sugar: Just a light sprinkle at the end gives a gentle caramelized finish.
How To Make Crispy Sweet Potatoes
Here’s exactly how I get that golden, caramelized edge on crispy sweet potatoes in the oven every single time, no fancy equipment needed. You’ll find every measurement and exact time in the recipe card below, but here’s how it actually goes down in my kitchen.
Tip: Don’t crowd the pan. If your potatoes are touching, they’ll steam instead of crisp, and steaming is the enemy here.
Crispy Baked Sweet Potato Variations
- If you want to dress up these crispy baked sweet potatoes a little, a small pinch of smoked paprika or garlic powder blends right in with the olive oil, salt, and pepper already in the mix.
- Fresh rosemary or thyme softens as the potatoes roast and fills the kitchen with a warm, comforting smell that I especially love in the fall.
- A light sprinkle of fresh parsley after they come out of the oven brings a nice bright finish if you want a little color on the platter.
- If rings aren’t your thing, you can cut these into cubes instead using the exact same method. They’ll just crisp up a touch faster since there’s more surface area exposed, or if you’d rather skip the oven entirely, my crispy sweet potato wedges post walks through the air fryer version.
- And like I mentioned, orange, Garnet, Diane, and Burgundy sweet potatoes have all worked well for me. The same sheet-pan method is exactly how I make my roasted Brussels sprouts and sweet potatoes, if you want to round out the meal with something green.
Questions When Making Crispy Sweet Potatoes
The biggest one is crowding the pan, something I learned the hard way the first time I doubled this recipe and ended up with a limp, steamed batch instead of crisp edges. Skipping the foil-covered start or forgetting to flip the slices partway through are the other two mistakes that most often lead to soft, pale sweet potatoes instead of golden ones.
No, this recipe doesn’t call for soaking the sweet potatoes beforehand. The cold-oven start and the covered-then-uncovered roasting method do the work of softening the centers and crisping the edges without any extra prep step.
For this recipe, yes, the sweet potatoes are peeled before slicing into rings. Peeling gives you a smoother texture and lets the caramelized edges form evenly all the way around each slice.
No, this recipe is best made fresh right before serving. The crispy edges soften once the potatoes sit for a while, so I don’t recommend prepping this dish ahead or holding a big batch for later.

Gina’s Notes and Tips
- Storage: Store leftovers in an airtight container for 3 to 4 days. The slices will soften slightly, but the flavor remains rich and comforting.
- Reheating: Warm the sweet potatoes in a 400°F oven for 8 to 10 minutes until the edges revive their crispness. Reheat them early so you can enjoy your guests without rushing.
- Substitutions: Avocado oil works well in place of olive oil. Jewel, Red Garnet, Diane, and Burgundy sweet potatoes have all been tested and roast into crisp, golden slices with excellent flavor. White-fleshed sweet potatoes work too, though they roast to a lighter color.
- Variations: Cubes can be used instead of rings using the same roasting method, though cubes will crisp a little faster. A small pinch of smoked paprika or garlic powder blends well with the oil, salt, and pepper. Fresh rosemary or thyme softens as the potatoes roast and adds a warm aroma. A light sprinkle of fresh parsley after baking brings a bright finish.
