Ingredients

• 1.5 kilograms Potatoes
• 500 milliliters Whole milk
• 50 grams Unsalted butter
• 2 large Egg
• 2 tablespoons Brown sugar
• 0.25 teaspoons Ground nutmeg
• 0.25 teaspoons Ground white pepper
• 1 teaspoons Salt
• 2 tablespoons Breadcrumbs
• 20 grams Butter (for greasing and topping)

Directions

Step 1

Preheat your oven to 175°C (350°F). Grease a casserole dish with butter and set aside.

Step 2

Peel and cut the potatoes into evenly sized chunks. Place them in a large pot of salted water and bring to a boil. Cook for 15-20 minutes or until tender.

Step 3

Drain the potatoes and return them to the pot. Mash thoroughly with a potato masher until smooth or use a ricer for an extra creamy consistency.

Step 4

Heat the milk and butter in a small saucepan over low heat until the butter melts. Gradually mix this into the mashed potatoes, stirring to combine.

Step 5

Beat the eggs in a separate bowl and add them to the mashed potatoes. Mix in the brown sugar, nutmeg, white pepper, and salt. Stir until all ingredients are well incorporated.

Step 6

Transfer the mashed potato mixture into the prepared casserole dish. Smooth the surface with a spatula. Sprinkle breadcrumbs evenly on top and dot with small pieces of butter.

Step 7

Bake the casserole in the preheated oven for 50-60 minutes, or until the top is golden brown and slightly crisp.

Step 8

Remove from the oven and allow to cool for 10 minutes before serving. Enjoy as a side dish or on its own!
