In a food processor, combine the chickpeas, onion, garlic, parsley, cilantro, cumin, coriander, baking soda, salt, and pepper. Pulse until well combined. Make sure to maintain a coarse texture.
Transfer the mixture to a bowl and refrigerate for at least 30 minutes to allow it to firm up.
Preheat your oven to 375°F (190°C) and line a baking sheet with parchment paper.
Shape the chilled falafel mixture into small balls or patties, approximately 1-2 inches in diameter, and place them on the prepared baking sheet.
Bake the falafel for 25-30 minutes, flipping halfway through, until they turn golden brown and crispy.
