Smoked Mackerel Fishcakes with Tartare Sauce
Why this recipe works
- Crisp outside, soft centre: Breadcrumbs create a golden crust while the mashed potato and flaked mackerel stay tender inside.
- Brightness balances richness: Lemon zest, lemon wedges and tartare sauce cut through the oiliness of the smoked mackerel.
- Easy to prepare in stages: The fishcakes can be shaped and chilled before frying, which also helps them hold together in the pan.

Ingredient notes
- Choose well-flavoured smoked mackerel: Smoked mackerel is the main flavour, so use fillets with a clean smoky aroma and remove any skin or small bones before mixing.
- Check seasoning carefully: Smoked fish and tartare sauce can already be salty, so taste the potato mixture before adding any extra seasoning.
- Use fresh herbs where possible: Fresh parsley keeps the fishcakes bright; dill is a good alternative if you want a more classic fish-and-herb flavour.
Texture tips
- Steam-dry the potatoes: Returning the drained potatoes to the hot pan briefly removes excess moisture and helps the fishcakes hold their shape.
- Chill before coating: A short chill after shaping firms the patties, making them easier to bread and less likely to break during frying.
- Serve straight from the pan: The breadcrumb coating is at its crispest immediately after frying, before steam softens the crust.
Make-ahead tips
- Shape ahead: Form the fishcakes in advance and chill them until ready to coat and fry.
- Freeze cooked fishcakes: Cool completely, freeze in a sealed container, then defrost overnight in the fridge before reheating.
- Reheat until piping hot: Warm on a baking tray at 200°C (390°F) or in a frying pan over a low to medium heat until heated through.
Serving ideas
- Serve with something fresh: A crisp green salad, peas or lightly dressed cucumber work well against the richness of the smoked fish.
- Keep tartare on the side: Serving the sauce separately preserves the crisp coating and lets each person add as much sharpness as they like.
- Finish with lemon: A final squeeze of lemon brightens the fishcakes just before eating.

Ingredients
Instructions
- Peel the potatoes and cut into even chunks. Put them in a large pot, cover with cold water, and bring to the boil. Simmer for 12 to 15 minutes until very tender.
- Meanwhile, finely slice the spring onions and finely chop the parsley. Zest the lemon, then cut it into wedges and set aside for serving. Flake the smoked mackerel, discarding any bones you find.
- Drain the potatoes well, then return them to the hot pot for 1 minute to steam-dry. Mash until smooth, then stir in the lemon zest, spring onions and parsley. Fold in the mackerel and mix until evenly combined.
- Divide the mixture into 8 portions and shape into fishcakes. Put the plain flour on a plate, beat the egg in a shallow bowl, and tip the breadcrumbs onto a second plate. Coat each fishcake in flour, then egg, then breadcrumbs, pressing gently so the coating sticks.
- Heat the olive oil in a frying pan over a medium heat. Fry the fishcakes for 3 to 4 minutes per side until crisp and golden, turning carefully with tongs. If the pan looks dry, add a splash more oil from the measured amount as needed.
- Serve the fishcakes hot with tartar sauce and the lemon wedges for squeezing. If you are cooking in batches, keep the first batch warm while you finish the rest. Eat straight away for the crispest coating.
Recipe notes
Tips
- For neat fishcakes, chill the shaped patties for 10 minutes before breading so they firm up and are easier to handle.
- If you are serving anyone who is pregnant, elderly, or immunocompromised, use pasteurised egg if available and ensure the fishcakes are piping hot throughout.
Substitutions
- Replace Yukon Gold potato with russet potato for a fluffier mash that still holds together well.
- Replace olive oil with vegetable oil for a more neutral frying flavour.
- Replace fresh parsley with fresh dill for a more classic fishcake flavour.
Storage
- Refrigerate up to 2 days
- Cool the cooked fishcakes completely, then refrigerate in a sealed container for up to 2 days. Reheat on a baking tray in a 200°C (390°F) oven for 10 to 12 minutes until piping hot, or warm in a frying pan over a low to medium heat. Freeze cooked fishcakes for up to 2 months; defrost overnight in the fridge before reheating.
