Tips & Tricks

Cut evenly. Even-sized cubes ensure everything cooks at the same rate.
Do not overcrowd the pan. Sweet potatoes need space to crisp; use two pans if necessary.
High heat is key. 425°F caramelizes the edges and prevents steaming.
Add Parmesan at the end. Adding it too early causes burning.
For extra crispiness:

• Toss potatoes with 1 teaspoon cornstarch before roasting.
• Use a dark metal sheet pan for better browning.
