Egg Gratin with Mashed Potatoes

Directions

  1. Cook the potatoes: Place peeled and cubed potatoes in a saucepan with water. Boil over medium heat for 20 minutes, or until tender. Drain and mash with cream and half the butter until smooth. Season with salt and pepper.
  2. Prepare the leeks: While the potatoes cook, clean and slice the white parts of the leeks. Cook in a small saucepan with 100 ml water for 10 minutes, or until tender. Drain and set aside.
  3. Cook the eggs: In another pot, place eggs in salted water and cook over medium heat for 10 minutes. Remove and rinse in cold water. Peel and cut in half.
  4. Make the béchamel: In a medium saucepan over low heat, melt the remaining butter. Stir in the flour and cook for 1–2 minutes to form a roux. Gradually add milk, stirring constantly until smooth and slightly thickened. Add grated cheese, season with salt and pepper, and cook for an additional 3 minutes until fully incorporated.
  5. Combine potatoes and leeks: Mix the cooked leeks into the mashed potatoes and season with salt and pepper. Spread the mixture evenly into a greased baking dish.
  6. Add the eggs: Place the halved eggs on top of the potato-leek mixture, pressing gently so they stay in place.
  7. Top with béchamel: Pour the cheesy béchamel sauce evenly over the eggs and mashed potatoes.
  8. Bake: Preheat oven to 180°C (350°F). Bake for 15 minutes, until the top is lightly golden and bubbling.
  9. Serve: Garnish with chopped parsley if desired. Serve immediately while warm.
