Sweet pea fish pie

Topped with lovely pea mash

Topped with lovely pea mash

“Fish pie is one of my favourites and seems to be one of yours, too. This clever, delicious, thrifty dish makes use of your freezer staples – and I have to say, it’s one of my best (using smashed sweet peas in the mash is a revelation). Traditionally, fish pies have always been about stretching fish a long way, and by using quality frozen fish fillets you make this even more budget-friendly. ”

Method

  1. Preheat the oven to 180°C/350°F/gas 4.
  2. Peel the potatoes and cut into large even-sized chunks, then cook them in a large pan of boiling salted water for 15 minutes, or until soft, adding the peas for the last 2 minutes. Drain and mash well with a pinch of sea salt and freshly ground black pepper, the zest from the lemon and the butter. Set aside.
  3. Peel and chop the carrots and onions, then fry them in a large ovenproof pan (roughly 30cm in diameter) with 1 tablespoon of oil over a medium heat for 15 minutes, or until softened but not coloured, stirring occasionally.
  4. Meanwhile, heat the milk in a pan on a medium heat. Once simmering, add all the frozen fish fillets and cook for around 10 minutes, or until cooked through, then use a slotted spoon to transfer them to a plate, taking the pan off the heat.
  5. Stir the flour into the carrots and onions, then gradually add the warm milk, a ladleful at a time, stirring continuously until you have a smooth sauce. Stir in the spinach until thawed and incorporated, then season to perfection.
  6. Flake in the cooked fish fillets (carefully remove and discard any skin or bones), add the prawns and mustard, along with the juice of half the lemon, grate in the Cheddar, and stir gently to combine.
  7. Top with the pea-spiked mash and smooth out, scuffing it up slightly with a fork to give it texture that will crisp up. Bake for 30-40 minutes, or until beautifully golden. Serve with a good old helping of baked beans (if you like). Delicious!

Tips

BUDGET-FRIENDLY MEAL PLAN TIPS:
This big-batch fish pie serves 8, so you can eat half straight away and cool and freeze the remaining half to enjoy in week 4.

EASY SWAPS:
I’ve used a mixture of frozen salmon, white fish and prawns in this recipe, but you can use whatever you’ve got in the freezer – just aim for the same total weight, about 600g. Replacing prawns with extra white fish will make this more budget-friendly.

Don’t worry if you don’t have any frozen spinach – leave it out this time and pick some up next time you’re shopping. It’s great in so many dishes.

HOW TO FREEZE & DEFROST YOUR BATCH RECIPES:
Just remember – if you’re batch cooking, let food cool thoroughly before freezing – break it down into portions so it cools quicker, and get it into the freezer within 2 hours. And make sure everything is well wrapped, and labelled for future reference so you’re not playing freezer roulette! Simply thaw in the fridge before use, and use within 48 hours. If you’ve frozen cooked food, don’t freeze it again after reheating it.

What is the difference between fish pie and fisherman's pie? ›

In place of a pastry casing enclosing the pie, a topping of mashed potatoes (sometimes with cheese or vegetables such as onions and leeks added) is used to cover the fish during baking. The dish is sometimes referred to as "fisherman's pie" because the mashed potato topping is similar to that used for shepherd's pie.

Bake the pie for at least 35 to 40 minutes, turning the oven down if the pastry starts to get too brown. The core temperature will need to be at least 75 C. Once cooked, allow to cool slightly before serving.

Why does my fish pie sauce split? ›

For the fish pie if you are using raw fish and then pouring the sauce over before baking it could be that the fish is letting out some liquid as it cooks in the oven, which would also either thin the sauce or give it the appearnace of curdling. This may particulalry happen if the fish has been frozen and thawed.

Why do you put baking soda in peas? ›

A teaspoon of bicarbonate of soda can be added to the peas whilst soaking or cooking (to speed up the softening process), but you can still achieve that perfect creamy texture with nothing but water - unless your water is especially hard.

Why do you soak peas before cooking? ›

Soaking is strongly recommended for all beans and peas, except lentils and black-eyed peas, for even cooking and to remove water-soluble, gas-producing starches. Soaking can be done using the traditional or the quick-soak method. TRADITIONAL METHOD: Clean and rinse beans; cover with three times as much water as beans.

Is pea purée the same as mushy peas? ›

Do not mistake pea purée for mushy peas. This recipe is made using fresh or frozen garden peas and fresh mint which are cooked quickly and mashed or puréed. Mushy peas are dried marrowfat peas that undergo a long, slow cook with bicarbonate of soda to make the peas swell and burst into a "mush."

How do you make fish not watery? ›

How do you keep baked fish from getting soggy? ›

Pat dry with paper towels whether you rinse or not. Preheat the oven to 450°F for fillets and steaks or 350°F for dressed fish. Even thickness: Place the fish in a single layer in a greased shallow baking pan (like a baking sheet). For fillets, tuck under any thin edges so they don't cook faster than thicker areas.

How do you keep pie base from going soggy? ›

Sprinkle dried breadcrumbs or crushed cornflakes, or other types of cereal, on the bottom crust before filling and baking in the oven. The layer will absorb moisture and prevent the filling from turning the crust soggy.

Why does my pie have so much liquid? ›

People often pull their pie too soon out of fear that it will burn. This leads to runny pie because it prevents the filling from thickening. Check the recommended cooking time, and set a timer. Don't use the brownness of your pie crust to judge if it is done.
