Ingredient Notes

Here’s a quick overview of the key ingredients for this recipe. For the full list of ingredients and exact measurements, be sure to check the recipe card at the bottom of this post.

  • Sweet potatoes: Choose firm, smooth-skinned potatoes. Medium-sized, long-shaped ones are easiest to peel and slice into even-sized pieces.
  • Olive oil: Helps the edges brown. Avocado oil works nicely, too.
    Salt and Pepper: Fine sea salt seasons the potatoes evenly. Freshly ground adds the best flavor.
  • Brown sugar: A light sprinkle gives a gentle caramelized finish. Leave it out if you prefer an entirely savory side. Maple sugar can replace brown sugar if you want a naturally sweet option.

How to Make Crispy Roasted Sweet Potatoes

Cut the peeled sweet potatoes into even ½-inch rings so they roast at the same rate. You will notice how easy they are to slice when you use medium-sized sweet potatoes. Coat them with olive oil, salt, and pepper until every piece looks lightly glossy.

Spread the slices in a single layer on a parchment-lined baking sheet.

Cover the pan tightly with another sheet of foil. Slide the pan into a cold oven, then turn the heat to 425°F. The gentle warm-up helps the centers soften without drying the edges.

Remove the top sheet of foil once the potatoes have softened. Return the pan to the oven so the bottoms can turn golden.

Flip each slice carefully so the other side can brown. If you enjoy a little sweetness, sprinkle a touch of brown sugar on top. When done, let the sweet potatoes cool briefly, then arrange them on a platter. They will hold their shape well and look beautiful on the table.

Variations, Substitutions, and Recipe Tips

Dietary modifications: These roasted sweet potato slices are naturally gluten-free and dairy-free, and they’re easy to adapt for low-sugar diets. If you prefer the potatoes without added sweetness, skip the brown sugar at the end. They will still caramelize gently in the oven and stay tender in the center with beautifully crisp edges.

Flavor enhancements: A small pinch of smoked paprika or garlic powder blends beautifully with the olive oil, salt, and pepper already in the recipe. Fresh rosemary or thyme softens as the potatoes roast and adds a warm, comforting aroma that pairs well with simple weeknight meals or holiday tables. After baking, light sprinkle of fresh parsley at the end brings a bright, fresh finish.

Simple substitutions: Avocado oil works well in place of olive oil, and either Jewel or Red Garnet sweet potatoes will roast into crisp, golden slices with excellent flavor. If you’d rather use cubes instead of rings, the same roasting method applies, though cubes will crisp a little faster. White-fleshed sweet potatoes can be used too, though they will roast to a lighter color.

Tips for recipe success: Flip gently so the rings keep their shape, and serve the potatoes soon after roasting so the caramelized edges stay crisp and inviting when friends gather around your table.

How do you make roasted sweet potatoes crispy?

Roast at high heat, give the potatoes plenty of space on the pan, and expose their edges to direct heat once softened.

What temperature is best for crispy sweet potatoes?

A 425°F oven creates caramelized edges and tender centers. Be sure to start with a cold oven and bring up to temperature.

Do you have to peel sweet potatoes before roasting?

Peeling gives the softest interior, but the skin can stay on if you prefer a rustic texture.

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.
