Jamie Oliver Haddock Fishcakes Ingredients List
Serves 4
- 400 g haddock fillets (skin removed)
- 500 g potatoes (peeled and chopped)
- 1 tbsp butter
- 1 tbsp olive oil
- 1 small onion (finely chopped)
- 2 tbsp fresh parsley (chopped)
- Zest of ½ lemon
- Salt and black pepper
- 1 egg (beaten, for coating)
- 60 g breadcrumbs
- Extra oil for frying
Optional:
- 1 tsp Dijon mustard
- Pinch paprika
How to Prepare Jamie Oliver Haddock Fishcakes – Simple Steps
Step 1: Cook the Potatoes Properly
Boil potatoes in salted water for 15 minutes until fork-tender. Drain thoroughly and allow steam to escape for a few minutes before mashing.
Dry mash prevents the fishcakes from becoming soft or watery.
Mash with butter until smooth but not overly creamy. Set aside to cool slightly.
Step 2: Cook the Haddock Gently
Place haddock in a shallow pan with a splash of water. Cover and cook gently for 4–5 minutes until just cooked through and flaky.
Avoid overcooking — haddock should flake easily but remain moist. Let it cool slightly, then flake into large pieces.
Step 3: Build the Fishcake Mixture
In a pan, heat olive oil and soften chopped onion for 4–5 minutes until translucent. Do not brown.
Combine mashed potato, flaked haddock, softened onion, parsley, lemon zest, salt, and pepper.
Mix gently. Overmixing breaks down the fish and creates a dense texture. The mixture should hold together but still show flakes of fish.
Step 4: Shape the Fishcakes
Divide the mixture into 6–8 equal portions and shape into patties about 2 cm thick.
Chill for 20 minutes if time allows. Chilling firms them up and reduces breakage during frying.
Step 5: Coat and Fry
Dip each fishcake into beaten egg, then coat in breadcrumbs.
Heat oil in a frying pan over medium heat. Fry fishcakes 3–4 minutes per side until golden brown.
Do not move them too early — allow a crust to form before flipping.
Step 6: Rest Before Serving
Place on a paper towel briefly to remove excess oil. Let rest 2–3 minutes before serving to allow the structure to settle.

FAQs
Can I use smoked haddock instead of fresh haddock?
Yes, smoked haddock works very well and adds a deeper, slightly salty flavour. If using smoked fish, reduce added salt in the mixture and taste before shaping the fishcakes.
Why are my haddock fishcakes falling apart when frying?
This usually happens if the mash is too wet or the mixture wasn’t chilled. Make sure the potatoes are well drained, keep the mash firm, and chill the shaped patties for at least 20 minutes before frying.
Can I bake haddock fishcakes instead of frying them?
Yes. Place them on a lined baking tray, brush lightly with oil, and bake at 200°C for about 20–25 minutes, turning halfway. They won’t be as crispy as pan-fried, but will still hold their shape well.
Can haddock fishcakes be frozen?
Yes. Freeze them uncooked on a tray until firm, then store in an airtight container for up to 1 month. Cook directly from frozen, adding a few extra minutes to the cooking time.
Final Words
Good fishcakes rely on balance — firm mash, flaky fish, and patient frying. With proper preparation and careful heat control, you’ll achieve a crisp exterior and tender centre every time.
