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.

  1. Bring a saucepan filled with lightly salted hot water to a boil. Roughly chop the parsnips into 1-2cm chunks (peel optional), then add to the saucepan. Simmer for 12-15 mins, until soft, then drain. Return to the pan and mash.
  2. Meanwhile, dissolve the cornflour in a jug with 2 tbsp cold water then add the stock cube and top up to 350ml with boiling water.
  3. Trim and thinly slice the leeks. Dice the carrot into 1cm cubes (peel optional). Thinly slice the mushrooms. Heat a large frying pan with 2 tbsp oil on high heat. Add the carrot and pork, cook for 4-5 mins, until golden. Add the leek, mushrooms, garlic herb paste and sage. Cook for 6-8 mins, until softened. Pre-heat the grill to high.
  4. Add the stock and cashew cream to the pork, bring to a boil then simmer for 4-5 mins, until the sauce has thickened. Season with sea salt and black pepper to taste, then transfer it to an oven-proof dish.
  5. While the sauce is thickening, roughly chop the chives and stir them into the parsnip mash along with 2 tsp oil, the dijon mustard and a good pinch of sea salt and black pepper. Spoon the parsnip over the top of the pork casserole and place under the grill for 5-6 mins, until starting to bubble and turn golden.
  6. Trim the green beans. Rinse out the saucepan used for the mash, fill it with salted hot water and bring to a boil. Add the green beans and boil for 2-3 mins, until cooked. Drain, then season with sea salt and black pepper.
  7. Serve the creamy pork casserole on plates alongside the green beans.
