01 - Preheat your oven to 400°F. Grease a 24-cup mini muffin tin with non-stick cooking spray or butter to prevent sticking.
02 - In a large mixing bowl, combine the thawed and dried hashbrowns, shredded sharp cheddar cheese, crumbled bacon (if using), chopped green onions, fresh chives, eggs, sour cream, garlic powder, onion powder, salt, and black pepper. Stir until all ingredients are evenly distributed.
03 - Spoon the mixture evenly into each cup of the prepared mini muffin tin, pressing gently to compact each portion firmly.
04 - Bake for 20 to 25 minutes, or until the tops are golden brown and crispy with the edges well-set.
05 - Allow the bites to cool in the pan for 5 minutes. Carefully remove each bite using a spoon or small spatula.
06 - Serve warm, garnished with additional fresh chives or alongside sour cream, ranch dressing, or hot sauce as desired.
