Preheat oven to 400° and grease a large baking sheet with cooking spray. In a large bowl, stir together hash browns, 2 eggs, and ½ cup of cheddar cheese and season with salt and pepper.
Transfer hash brown mixture to prepared baking sheet and, using your hands, pat into a circular crust. Bake until golden, 20 minutes.
In a large nonstick skillet over medium heat, cook bacon until crispy, 8 minutes. Drain on a paper towel-lined plate, then chop.
Top baked crust with remaining 1½ cups cheddar cheese and crack remaining 4 eggs on top. Scatter bacon over everything and season with salt and pepper.
Bake until egg whites are set but yolks are still slightly runny, 15 minutes. (If you prefer a less runny yolk, bake 18 to 20 minutes.)
Garnish with chives and slice.
