Preheat the oven to 400°F (200°C). Line one or two baking sheets with parchment paper.
In a large bowl, combine the chickpeas with the olive oil, lemon zest and juice, salt, za'atar, sumac, harissa, and paprika and toss to coat.
Spread the chickpeas in a single layer on the prepared baking sheets.
Roast, shaking the baking sheet and stirring the chickpeas every 10 minutes, for 30 to 40 minutes total, or until golden and crispy.
Store in an airtight container for up to 3 days.
