Notes
Tips for the Crispiest Roasted Sweet Potatoes
Space the potatoes out.
Overcrowding the pan causes steaming instead of roasting.
Cut into even pieces.
Uniform cubes roast at the same speed.
Use high heat.
425°F is ideal for crisp edges without burning.
Add cheese AFTER roasting.
Parmesan can burn easily — adding it at the end keeps it flavorful.
