                Preheat the oven to 375 degrees. In a large skillet (a 15 inch cast iron works well), heat the butter until melted and slightly frothy.

                Add the cabbage and combine with onions. Season with salt. Cook for about 5-6 minutes or until the cabbage has softened and is beginning to turn lightly golden in spots.

                Add the frozen hash browns and 1½ cups of cheese and mix until well-combined. Smooth the top with a spatula.

                Add the remaining cheese to the top and bake for another 4-5 minutes until the cheese is melted and bubbly.
