Potatoes, Raw

700 g

Semi Skimmed Milk

2 tablespoon(s)

Dijon Mustard

2 teaspoon(s), level

Plain White Flour

15 g

Vegetable stock cube

½ cube(s), made with 300ml vegetable stock

Half Fat Crème Frâiche

3 tablespoon(s), level

Dill, Fresh

1 tablespoon(s), chopped

Calorie controlled cooking spray

4 spray(s)

Fish pie mix

450 g, cut into chunks

Peas, frozen, boiled

150 g

Parmesan Cheese

15 g


2 medium

Green Beans

4 portion(s), medium

Low Fat Spread

15 g

Lemon Juice, Fresh

20 ml


  1. Preheat the oven to 180°C, fan 160°C, gas mark 4.
  2. Cook the potatoes in a pan of boiling water for 15 minutes or until soft. Remove from the heat and drain, then mash roughly with a potato masher, adding the semi-skimmed milk. Stir through the mustard, then season and set aside.
  3. Melt the low-fat spread in a pan and heat until foaming. Stir in the flour to form a paste and cook over a gentle heat for 1-2 minutes, before slowly adding the stock. Do this a little at a time, whisking well, so there are no lumps. Once you have a smooth sauce, simmer for 5 minutes until thickened. Remove from the heat and stir through the crème fraîche and dill. Season to taste.
  4. Mist a 1.5-litre pie dish with cooking spray. Add the fish and peas to the sauce and stir gently to combine, then tip into the pie dish. Top with the mashed potato, scatter over the parmesan and bake for 20 minutes until golden and bubbling. Serve with the steamed veg and lemon wedges.


Try different toppings instead of potato. Cooked and mashed celeriac or sweet potato both work well.
