Ingredients

Haddock fillets — skin removed and cut into bite-sized pieces (quantity not specified).
Pre-cooked prawns — opened; added with the haddock (quantity not specified).
Spring onions — about 3, cleaned and finely chopped.
Mashed potato — cold and stiff (homemade preferred; packet instant acceptable as a shortcut).
Butter and plain flour — equal quantities for the roux (presenter uses ~50 g butter + 50 g flour).
Milk — added to make a thick white sauce (amount adjusted to reach desired consistency).
Extra butter — a knob or two to enrich the sauce.
Wholegrain mustard — about 1 teaspoon.
Salt and black pepper — to taste (use salt carefully if using salted butter).
Fresh herbs: parsley (a handful), tarragon (8–10 leaves), and a small amount of dill.
Lemon — zest of ~½ lemon + juice (start with ~¼ lemon’s juice, then adjust).
Frozen peas (for sweetness and bulk); sweetcorn optional.
Mature cheddar — grated generously for the top.

Substitutions & Variations (overview)

Fish: mix two types (e.g., salmon, smoked haddock, scallops, king prawns) for a premium version.
Budget fish: pollock or basa.
Vegetables: peas or sweetcorn (or both).
Dried herbs may be used sparingly (tarragon is punchy).
Mashed potato: packet instant is fine if it’s chilled until stiff.

Equipment & Prep

Heavy pan for the white/milk-based sauce.
Knife and chopping board.
Grater for lemon zest and cheese.
Ladle for filling the pie dish.
Pie dish or ovenproof dish; baking tray with a square of foil under the dish to catch spills.
Fork (to spread mash) or a piping bag (optional for piped mash).
Oven: preheat to 180°C fan (200°C conventional).
Allow filling to cool to room temperature before topping.

Method

Prep fish and aromatics
- Remove haddock skin (won’t crisp in the pie) and cut into small bite-sized chunks.
- Open pre-cooked prawns.
- Trim and rinse ~3 spring onions, remove any stringy outer layer, and chop finely.
- Chop herbs: a handful of parsley, ~8–10 tarragon leaves, and a little dill — chop finely.
Make mashed potato ahead
- Prepare mash in advance and chill until cold and stiff (presenter references his Kitchen Basics mash recipe).
Make the sauce (a richer béchamel)
- On moderate heat, combine equal quantities of butter and plain flour (about 50 g each) and cook into a paste. Cook until the texture is sandy and the raw flour taste is gone.
- Add milk gradually in small splashes, whisking between additions to avoid lumps. Aim for a very thick sauce (around the thickness of extra-thick double cream).
- Add a knob or two of butter to enrich the sauce and whisk to combine.
- Stir in ~1 tsp wholegrain mustard, black pepper, and salt carefully (taste as you go).
- Add the chopped spring onions and chopped herbs, then turn the heat off.
Finish the sauce with lemon and veg
- Off the heat, add lemon zest (~½ lemon) and start with ~¼ lemon juice; adjust to taste. (Add juice off the heat to avoid curdling.)
- Stir in frozen peas (and/or sweetcorn) for sweetness and bulk.
Combine fish and sauce
- Off the heat, gently fold the haddock pieces and pre-cooked prawns into the sauce so the fish stays in chunks.
- Ladle the filling into a pie dish (extra filling can be cooled and frozen).
- Allow the filling to cool to room temperature before topping with mash — this prevents the mash sinking and the pie becoming gloopy.
Assemble and bake
- Preheat oven to 180°C fan (200°C conventional).
- Dot cold, stiff mashed potato on top of the cooled filling in dollops and use a fork to rough up the surface (piping is optional).
- Generously grate mature cheddar over the mash. Place the pie dish on a baking tray and put a square of foil under the dish to catch any spillage.
- Bake for 20–30 minutes until the cheese is melted, the top is golden, and the filling is bubbling (presenter used ~25 minutes).
- Let the pie rest for about 5 minutes before serving.

Key: cool the filling to room temperature before topping. Hot filling causes the mash to sink and the pie to become gloopy.

Chef Tips, Technique Notes & Common Mistakes

Remove haddock skin because it won’t crisp in the pie.
Cut fish into small pieces to stretch the filling and mimic the classic texture.
Use spring onions for an “oniony” note without cooking down whole onions.
Cook the roux long enough to remove raw flour taste — otherwise the sauce will be chalky.
Add milk gradually and whisk to prevent lumps (hot milk isn’t mandatory if you add slowly).
Make the sauce deliberately thick — fish releases juices during baking that will thin it.
Add lemon juice off the heat to avoid curdling.
Be sparing with tarragon — it’s strong.
Put foil under the dish on the tray to catch bubbling over.
Let the finished pie rest ~5 minutes before portioning.

Plating & Serving

Serve in wedges or portions straight from the pie dish after the 5-minute rest.
Presenter serves as a lunch portion; no special garnishes are mentioned.

Variations (concise)

Premium: haddock + salmon, smoked haddock, scallops, king prawns.
Budget: pollock or basa fillets.
Veg: sweetcorn instead of or alongside peas.
Leftovers: extra filling can be cooled and frozen for later.

Notes

Many quantities are qualitative; taste and adjust lemon, salt, and seasoning as you go.
The presenter emphasizes tasting as you go and adjusting to personal preference.
