Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper.
In a large bowl, add the drained chickpeas and pat them dry with a paper towel to remove excess moisture.
Drizzle the olive oil over the chickpeas and toss gently to coat them evenly.
Sprinkle the ranch seasoning, garlic powder, onion powder, smoked paprika, salt, and pepper over the chickpeas. Toss again to ensure the spices are well distributed.
Spread the seasoned chickpeas in a single layer on the prepared baking sheet.
Roast in the preheated oven for 25-30 minutes, stirring halfway through, until they are golden brown and crispy.
Remove from the oven and let cool slightly. The chickpeas will continue to crisp up as they cool.
Serve as a snack, topping for salads, or as a crunchy appetizer. Enjoy!
Notes
Let the chickpeas cool to achieve maximum crispiness.
