Preheat your oven to 400°F / 200°C.
Place the oil in a large, ovenproof skillet or roasting pan over medium heat on the stovetop.
Once the oil is hot, add the chickpeas and minced garlic.
Sprinkle generously with salt and pepper.
Shake the pan to coat the chickpeas evenly in oil and arrange them in a single layer for maximum crispiness.
Carefully transfer the skillet to the preheated oven.
Roast for 15-20 minutes, shaking the pan occasionally, until the chickpeas are golden brown and begin to crisp.
Remove from the oven and let them cool slightly in the pan. The chickpeas will continue to get crispier as they cool.
Taste and add any additional seasonings you desire (see !)
Serve warm or at room temperature.
Don't overcrowd the pan!
Spreading the chickpeas in a single, even layer is crucial for them to roast and get crunchy, rather than steam.
