Ingredients

Instructions

  1. Step
    Preheat oven to 200°C (400°F). Grease a baking dish (e.g. 9x13 inch) with a bit of butter.
  2. Step
    In a medium saucepan over medium heat, melt 3 tbsp butter. Whisk in flour and cook for 1 minute to make a roux. Slowly whisk in broth, then milk, stirring constantly until smooth. Add garlic, onion, chopped rosemary, nutmeg, salt, and pepper. Cook, whisking, until the sauce thickens enough to coat the back of a spoon (2–3 minutes).
  3. Step
    Place half the potato slices in the bottom of the prepared baking dish. Pour half the sauce over the potatoes. Sprinkle half the grated mozzarella. Repeat with the remaining potatoes, sauce, and cheese.
  4. Step
    Cover with foil and bake for 30 minutes. Remove foil and bake an additional 35–40 minutes, or until potatoes are tender and top is golden and bubbling.
  5. Step
    Let the dish rest about 15–20 minutes before slicing and serving to let it set.
