Description

A hearty and comforting layered dish made with creamy mashed potatoes, golden caramelised onions, juicy sausages, and a gooey melted cheddar cheese topping. Perfect for family dinners or cozy nights in.


Ingredients

Scale
  • 1.2 kg potatoes, peeled and chopped
  • 75 g butter
  • 100 ml milk or cream
  • 150 g cheddar cheese, grated
  • 6 pork or chicken sausages
  • 3 large onions, thinly sliced
  • 1 tbsp olive oil
  • Salt and pepper, to taste
  • Fresh thyme (optional)


Instructions

  1. Preheat your oven to 200°C (400°F) and grease your baking dish lightly.
  2. Boil potatoes in salted water until tender. Drain, then mash with butter and milk until smooth. Season with salt and pepper.
  3. Heat olive oil in a skillet. Add onions and cook on low heat for 25–30 minutes until golden and caramelised.
  4. In a separate pan, cook sausages until browned and fully cooked. Slice them into pieces.
  5. Layer half of the mash into the baking dish. Top with sausage slices, then add the caramelised onions. Finish with the remaining mash and sprinkle grated cheese on top.
  6. Bake for 25–30 minutes or until the cheese is golden and bubbly.
  7. Let rest for 5–10 minutes, garnish with thyme if using, and serve warm.

Notes

  • Use starchy potatoes like Maris Piper or Russet for best mash texture.
  • Freshly grated cheese melts better than pre-shredded.
  • Add a spoonful of mustard to mash for an extra flavor boost.
  • Let onions cook slowly to bring out their natural sweetness.
