01 - Preheat your oven to 400°F (200°C). Generously grease a 24-cup mini muffin tin with cooking spray or oil.
02 - In a large bowl, combine the thawed hashbrowns, cheddar cheese, bacon (if using), green onions, chives, eggs, sour cream, garlic powder, onion powder, salt, and pepper. Mix until ingredients are evenly distributed.
03 - Spoon the mixture evenly into the prepared muffin tin cups. Press down gently with a spoon or scoop to compact each portion.
04 - Bake for 20 to 25 minutes, or until the tops are golden brown and crispy.
05 - Let the bites cool in the pan for 5 minutes to set. Carefully remove them from the tin using a spoon. Serve warm, garnished with extra chives or a side of sour cream.
