Equipment
- large saucepan
- Potato Ricer
- 1 ½ quart casserole dish
- Nonstick spray
Ingredients
Potatoes
- 2½ pounds Yukon Gold potatoes, peeled and cut into large chunks
- 1 Tablespoon Kosher salt (for boiling water)
Casserole
- 6 Tablespoons unsalted butter, divided
- 1 small shallot, finely minced
- 1 ½ cup (6vounces) shredded Dubliner cheese, divided
- ½ teaspoon freshly grated nutmeg
- ¼ teaspoon Freshly ground black pepper
- ¾ cup (6 ounces) whole milk (See Tips 1 and 2)
- Salt to taste if needed
- 2 Tablespoons Panko breadcrumbs
- ½ cup (2 ounces) shredded Dubliner cheese
Instructions
Potatoes
- Place the peeled potatoes in a large saucepan and cover with cold water by several inches. Add the tablespoon of Kosher salt and bring to a boil. Cook until the potatoes are very tender, about 10 to 15 minutes after the water reaches a full boil. (See Tip 3)
- Drain the potatoes well, then let them sit in the colander for about 10 minutes to evaporate excess moisture.
Casserole
- Return the empty saucepan to medium heat. Add 5 tablespoons of butter and melt. Stir in the shallots and sauté for 2 to 3 minutes, just until softened and fragrant. Do not brown.
- Rice the drained potatoes into the saucepan, or mash until smooth with a potato masher. Fold in 1 cup of Dubliner cheese, nutmeg, black pepper, and milk until well incorporated, adding additional milk if needed. Adjust the seasonings.
- Preheat the oven to 400°F. Spray a 1 ½-quart casserole dish with nonstick spray.
- Transfer the mashed potatoes to the prepared casserole dish and spread to an even thickness. May be prepared in advance up to this point. (See Tip 3)
- Sprinkle the top of the casserole with the remaining ½ cup of shredded Dubliner cheese and Panko breadcrumbs. Dot with 1 tablespoon of the remaining 1 tablespoon of unsalted butter.
- Bake in a preheated 400°F oven for 25 to 30 minutes or until bubbly and golden brown.
- Bake for 25–30 minutes until the casserole is heated through and the top is golden and crispy.
- Allow the casserole to rest for 5 minutes before serving. If desired, top with sliced green onion tops or minced chives.
- Yield: 6 servings.

Notes
- May substitute half-and-half or cream for the milk.
- Add additional milk if needed to achieve the proper consistency of the potatoes.
- To prevent the water from boiling over, place a wooden spoon or fork in the pan.
- If preparing the potatoes in advance, cover the casserole dish and refrigerate for up to 24 hours. Add 10 to 15 minutes to the baking time.
