Prepare Your Cooking Vessel:
Spread the mashed potato mixture evenly in your prepared dish. Smooth the top so the gratin can crisp up beautifully.
Assemble the Dish:
In a small bowl, mix grated parmesan with minced garlic and a drizzle of olive oil or melted butter. Sprinkle this glorious mixture over the mashed potato base.
Cook to Perfection:
Bake uncovered for 25–30 minutes, or until the parmesan top is golden and bubbling with crispy edges.
Finishing Touches:
Let it cool for 5–10 minutes to set. This makes slicing and serving a breeze and the flavors really settle.
