Ingredients

  • 750 g potatoes (firm or waxy)
  • Salt
  • 600 g frozen Brussels sprouts
  • 3 onions
  • 1 tbsp oil (10 ml)
  • 100 ml milk
  • 50 g butter
  • freshly grated nutmeg
  • 100 g medium-aged Gouda cheese (48% fat in solids)

Instructions

  1. 1.

    Wash, peel, and boil the potatoes in a pot of salted water for 20-25 minutes until tender. Drain and mash with a potato masher.

  2. 2.

    Thaw frozen Brussels sprouts if needed or clean and wash fresh ones. Peel onions and slice into rings. Heat oil in a pan over medium heat; sauté onions for 5-7 minutes until golden brown.

  3. 3.

    Warm milk in a saucepan over medium heat, then melt butter into it. Add the milk-butter mixture to the mashed potatoes and stir well. Finish by whisking vigorously with a fork and season with salt and nutmeg.

  4. 4.

    Place the mashed potato mixture into a greased baking dish. Drain the Brussels sprouts and press them lightly onto the potato layer. Distribute onions over the top and sprinkle shredded Gouda cheese on top. Bake in a preheated oven at 200°C (or 180°C fan) for about 20 minutes until the cheese is golden and bubbly.
