Preheat the oven to 425 °F (220 °C) and line a baking sheet with parchment paper, or preheat your air fryer to 400 °F (205 °C).
In a large bowl, combine the thawed and patted‑dry hash browns with shredded cheese, green onions, garlic powder, smoked paprika, salt, and pepper.
Add the beaten eggs and flour to the potato mixture and toss until everything is evenly coated and sticks together.
Scoop tablespoon‑sized portions of the mixture and shape them into small, compact bites, placing them on the prepared baking sheet (or directly in the air fryer basket) with a little space between each.
Bake for 20–25 minutes, flipping halfway through, until the bites are golden brown and crispy; if using an air fryer, cook for about 15–18 minutes, shaking the basket halfway through for even browning.
Once crisp and cooked through, remove from the oven or air fryer and let cool slightly and serve warm, topped with bacon bits, a dollop of sour cream, extra cheese, chives, or jalapeño slices as desired.
