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.
