Do I need to peel the sweet potato?

No. The skin becomes tender and adds fiber, but peeling is optional.

Why are my cubes not crispy?

They may be too crowded or not dried well before seasoning.

Can I make these without an air fryer?

Yes—bake at 425°F (220°C) for 25–30 minutes, flipping halfway.
