Cod & Leek Pie with Dill & Roasted Broccoli

Cod & Leek Pie with Dill & Roasted Broccoli

Nothing beats a good classic fish pie, starring responsibly-sourced cod, infused with fragrant dill in a creamy sauce. Spinach adds green to the filling. Potatoes create a fluffy mash topping. We dish up broccoli on the side, too. A generous sprinkle of cheese ups the comfort even more.

Cooking Instructions

The protein cooking time listed in this recipe has been updated.

As of December 2025, we’ve revised cooking times for all our proteins to reflect improved food safety guidance.

Check out the latest recommended times in our Cooking Guidelines.

Before you start

  • Preheat the oven to 240C / fan 220C / gas mark 9
  • Line a baking tray with parchment paper
  • Bring a large saucepan filled with salted water to a boil
  • Pull out a large lidded frying pan, a large baking dish, a measuring jug, a masher, a sieve, a peeler & a grater

Start the mash & prep

  • Peel and roughly dice the potatoes into 3cm chunks, then add to the saucepan
  • Simmer for 15-18 mins, until soft, then drain. Return to the pan and mash with 1/2 tbsp oil, salt and pepper
  • Meanwhile, trim and slice the leek into 1/2cm half-moons. Finely chop or crush the garlic. Zest and cut the lemon into wedges
  • Dissolve the half pack of cornflour in the jug with 50ml cold water, add the stock powder and top up with 150ml hot water

Simmer the filling

  • Heat the large frying pan with 1/2 tbsp oil on medium-high heat. Once hot, add the leek and cook for 4-5 mins, until starting to soften. Season with salt and pepper
  • Add the garlic and cook for 30 secs, then stir in the cashew cream and stock mixture. Bring to the a boil
  • Lay the cod chunks evenly in the sauce, then cover with a lid, lower the heat and simmer for 19 mins, until the fish is cooked through

Build the flavour

  • Meanwhile, cut the broccoli into florets. Rinse the spinach. Roughly chop the dill
  • In the final 2 mins, add the spinach, horseradish puree, lemon zest, a squeeze of lemon juice and the dill into the cod and cook until wilted. Finely grate in half the cheese. Season to taste
  • Check your fish is cooked through; it should be steaming hot, opaque and separate easily with a fork

Time to roast

  • Add the broccoli to the lined baking tray, and toss with 1 tsp oil and a pinch of salt and pepper. Roast the broccoli on the middle shelf for 10-15 mins, until soft and golden
  • Transfer the pie filling into the large baking dish and top with the mash. Grate the remaining cheese over the mash and roast on the top shelf for 10-12 mins, until golden and bubbling

Plate up

  • Serve the fish pie into bowls, with the broccoli alongside. Garnish with the remaining lemon wedges
