Directions

Preheat your oven to 450°F (230°C).

In a large bowl, whisk together cornstarch, salt, smoked paprika, and most of the olive oil. Add the cubed sweet potatoes and toss until fully coated.
Carefully remove the preheated baking sheet from the oven, drizzle with the remaining olive oil, and tilt to coat the surface. Pour the sweet potato mixture onto the hot sheet and spread into a single layer.
Roast until the sweet potatoes are golden and crispy, turning with a spatula every 10–15 minutes. Total roasting time is about 30–40 minutes.

FAQs

What size should I cut the sweet potatoes?

Cut them into roughly 3/4‑inch pieces so they cook evenly and crisp up well.

Can I leave the sweet potato skin on?

Yes — leaving the skin on adds fiber and helps the pieces hold together, but peeling is fine if you prefer.

Why use cornstarch?

Cornstarch helps absorb excess moisture from the sweet potatoes, promoting a crunchier exterior.

Do I need a preheated pan?

Preheating the baking sheet jump‑starts the roasting process, giving the potatoes a better sear and crispiness.

Can I use another oil?

You can substitute another high‑heat oil like avocado or canola, but olive oil works great for flavor.

What temperature is best for roasting?

A high temperature like 450°F helps caramelize and crisp the sweet potatoes.

How do I prevent soggy sweet potatoes?

Avoid overcrowding the pan so steam doesn’t build up. Spread the pieces in a single layer with space between them.

Can I add other seasonings?

Absolutely — try garlic powder, black pepper, cumin, or herbs to customize the flavor.

Are these good cold?

They’re best warm and crispy but can be enjoyed cold in salads or bowls.

Can I make them ahead?

They’re best fresh but you can roast ahead and reheat in the oven or air fryer for best texture.
