Rinse the chufa under cold water to remove any dirt or impurities.

Soak the chufa in water for 8-12 hours. Drain and pat dry.

Preheat the air fryer to 380°F (190°C).

In a bowl, toss the soaked chufa with olive oil, sea salt, and smoked paprika until evenly coated.

Place the chufa in a single layer in the air fryer basket.

Air fry for 15-20 minutes, shaking the basket halfway through for even cooking, until they are golden brown and crispy.

Remove from the air fryer and let cool slightly before serving.
