Preheat oven to 375°F. Line a baking sheet with parchment paper or a Silpat silicone mat.
Drain and rinse the chickpeas in a colander. Place them on a towel to dry off.
Spread chickpeas on a baking sheet in a single layer. Bake for approximately 45 minutes or until crispy. Test one, and if it's still soft, bake for longer.
