Gluten-Free Baked Mozzarella Potato Pie

A comforting casserole that transforms simple mashed potatoes into an elegant side dish. Yukon Gold potatoes are cooked with garlic until tender, then mashed with butter and milk before being topped with Parmesan and fresh mozzarella. The herbs add aromatic depth while the cheese creates a golden, bubbly top. Perfect for family dinners, holiday meals, or potluck gatherings. This version stands out for its creamy interior contrasted by the crispy, cheesy surface that develops during baking.

Tips
Remove excess moisture from cooked potatoes by stirring over heat until steam stops rising - this prevents a watery casserole
Let the pie rest for several minutes after baking as it will be extremely hot and easier to slice once slightly cooled
For extra flavor, roast the garlic separately and fold into mashed potatoes for a deeper, caramelized taste

Can be assembled up to 1 day ahead without final cheese topping, add cheese just before baking

Common Mistakes
Don't skip drying the potatoes after draining to avoid watery texture
Don't overmash or potatoes become gluey rather than creamy
