Set the oven to 400°F and place a large rimmed baking sheet inside to preheat for a crisp roast.

Rinse and drain chickpeas, then roll them in a clean kitchen towel until fully dry; remove loose skins for extra crunch if possible.
03 -
Toss the dried chickpeas with olive oil until evenly coated; do not add seasonings yet to prevent burning.
04 -
Spread chickpeas in a single layer on the preheated baking sheet and roast for 20 minutes, shaking the pan halfway through.
05 -
Remove the baking sheet, sprinkle ranch seasoning, smoked paprika, and a pinch of sea salt over chickpeas, and toss to coat evenly.
06 -
Return the chickpeas to the oven and roast for an additional 10 to 12 minutes until crisp and lightly browned.
07 -
Sprinkle grated Parmesan evenly over chickpeas and roast for 3 to 5 minutes until the cheese turns golden and the chickpeas are deeply crisp; watch carefully to avoid burning.
08 -
Turn off the oven, leave the door ajar, and let the chickpeas sit inside for 5 minutes to evaporate residual moisture. Transfer them to a wire rack and cool completely for approximately 15 minutes.

Adjust salt if necessary, then store fully cooled chickpeas in a paper-towel-lined glass jar at room temperature for up to 3 days. Re-crisp if softened by heating at 325°F for 5 to 8 minutes.
