This Cheese and Potato Pie recipe features mashed potatoes mixed with cheese, onions, and a dash of seasoning, topped with more cheese, and baked until golden and bubbly. It’s a rustic, home-cooked dish that’s comforting and perfect for chilly evenings. This vegetarian-friendly pie can be served as a main course or a side dish, making it versatile for any meal.
Preheat your oven to 200°C (400°F) and grease a medium-sized baking dish.
Place the chopped potatoes in a large pan of salted water and bring to a boil. Cook for about 15-20 minutes until the potatoes are tender. Drain them and allow them to sit for a few minutes to steam dry.
While the potatoes are cooking, heat the olive oil in a frying pan over medium heat. Add the chopped onions and cook until soft and lightly golden, about 10 minutes. Set aside.
Mash the cooked potatoes with butter and milk until smooth and creamy. Stir in the mustard, if using, and season with salt and pepper to taste. Then, fold in half of the grated cheddar cheese and the fried onions, mixing until well combined.
Spoon the mashed potato mixture into the prepared baking dish and spread it out evenly. Sprinkle the remaining grated cheddar cheese generously over the top.
Place the dish in the preheated oven and bake for 20-25 minutes, or until the top is golden brown and bubbly. For an extra crispy top, you can switch to the grill for the last 2-3 minutes.
Once the pie is baked and golden, remove it from the oven and let it cool for a few minutes. Garnish with chopped fresh parsley before serving. This dish is perfect served with a green salad or alongside grilled meats or vegetables.
