For an extra layer of flavor, try adding a clove of minced garlic to the butter while sautéing the green onions. If you prefer a smoother sauce, use an immersion blender to blend the sauce before layering it with the potatoes. For a crispier top, broil the au gratin potatoes for the last 2-3 minutes of baking, watching carefully to prevent burning. You can assemble the au gratin potatoes ahead of time and store them in the refrigerator for up to 24 hours before baking. Add an extra 10-15 minutes to the baking time if baking from cold.
