Ingredients
  

For the Potatoes

  • 2 pounds yellow potatoes peeled and cut into quarters (Note 1)
  • 2 and ½ teaspoons kosher salt divided (2 teaspoons + ½ teaspoon)
  • 4 tablespoons unsalted butter cut into small pieces
  • ½ cup whole milk (Note 2)
  • ¾ cup fresh mozzarella shredded or finely diced
  • ½ cup grated Pecorino Romano cheese
  • ¼ teaspoon ground black pepper
  • Handful Italian flat-leaf parsley minced

For the Panko Topping

  • ½ cup unseasoned Panko breadcrumbs
  • 1 tablespoon grated Pecorino Romano cheese
  • ½ teaspoon garlic powder
  • teaspoon kosher salt
  • Pinch ground black pepper
  • 2 tablespoons unsalted butter melted

Instructions
 

  • Boil the potatoes in a large pot of water with 2 teaspoons of kosher salt until fork tender, about 20 minutes. Drain the potatoes, then transfer them back to the pot.
  • Meanwhile, prepare the Panko topping by mixing all the ingredients together in a small bowl. Set aside.
  • Preheat the oven to 375°F.
  • Using a potato masher or food mill, mash the potatoes just until smooth. Stir in the remaining ½ teaspoon kosher salt, butter, milk, mozzarella, Pecorino, and pepper.
  • Pour the potatoes into a 1.5-quart casserole dish. Smooth the top with a spatula, then top with the seasoned Panko breadcrumbs.
  • Place the casserole dish on the oven's middle rack and bake for 20-25 minutes until the top is golden. If it's still too light, you can place it under the broiler for a bit, but watch it carefully! Garnish the casserole with the minced parsley.

Notes

Note 1: Ensure the potatoes are cut to a similar size so they boil evenly.
Note 2: The milk does not have to be heated.
General Notes:
  • Mash the potatoes just until smooth. Use a potato masher or food mill, which are less likely to turn the potatoes gluey.
  • You don't have to coat the dish with butter because the potatoes already have enough butter that they won't stick.
  • Make sure you bake uncovered so the top browns.
