  • 3 tbsp / 50g unsalted butter
  • 2 large leeks (, white and pale green part only, washed, cut in half lengthways, sliced 5mm / 0.2" thick OR 2 onions (Note 2))
  • 3 garlic cloves (, minced)
  • 2 medium starchy potatoes ((250g / 8oz each), peeled (Note 3))
  • 3/4 tsp cooking/kosher salt
  • 1/2 tsp black pepper
  • 1/2 cup dry white wine (, any type, sub more veg stock (Note 4))
  • 1/2 cup vegetable stock/broth (, low sodium)
  • 1 cup thickened/heavy cream
  • 3/4 cup panko breadcrumbs
  • 2 tbsp extra virgin olive oil
  • 1/4 cup parmesan (, finely shredded)

Steps

  1. 1

    Preheat the oven to 180°C/350°F (160°C fan) with a shelf in the middle.

  2. 2

    Potatoes - Cut the potatoes into quarters, then sliced 4mm / 1/6" thick. Place cut potato in a large bowl of water (prevents from going brown, removes excess starch so it cooks quicker). Drain before use.

  3. 3

    Crunchy topping: Mix panko and olive oil in a bowl. Then stir in parmesan.

  4. 4

    Season fish: Sprinkle salt and pepper on both sides of the fish fillets. Set aside.

  5. 5

    Sauté - Melt butter in a large oven-proof skillet (30cm/12") over high heat until foamy. Add leek and garlic, then cook for 3 minutes.

  6. 6

    Sauté potatoes - Add potato, salt and pepper. Cook for 6 minutes, stirring regularly. The potatoes should be half cooked at this stage.

  7. 7

    Reduce wine and stock - Pour in white wine. Simmer rapidly until it is mostly evaporated - about 1 minute. Pour in stock, then simmer for 1 1/2 minutes or until reduced by half.

  8. 8

    Top with fish - Turn the stove off. Place fish on top of the potatoes, presentation side up. (Note 1) Pour cream all over, aiming for full coverage. Sprinkle with panko breadcrumbs.

  9. 9

    Bake for 30 minutes - I know this sounds like a long time but the fish stays succulent!

  10. 10

    Colour topping - Switch to the oven grill (broiler) on high and move the skillet up to the top shelf. Grill/broil 4 minutes or until golden.

  11. 11

    Rest - Remove and rest for 5 minutes, then serve! Eat the fish and gratin together with each mouthful for maximum eating pleasure!!
