How to Make Smoked Haddock Fishcakes

1. Cook the Haddock

Place the smoked haddock in a pan of lightly simmering water.

Cook for 5–7 minutes until the fish is just cooked through.

Drain, remove any skin, and flake the fish into small pieces.

2. Mix the Fishcake Base

In a mixing bowl, combine:

  • Flaked haddock
  • Mashed potatoes
  • Egg
  • Breadcrumbs
  • Salt and black pepper

Mix until everything is evenly combined.

3. Shape the Fishcakes

Form the mixture into evenly sized patties.

Place them on a plate or tray.

4. Chill the Fishcakes

Refrigerate for about 15 minutes to help them firm up and hold their shape during cooking.

5. Pan-Fry

Heat oil or butter in a skillet over medium heat.

Cook the fishcakes for 4–5 minutes per side until golden brown and crispy.

6. Serve

Serve the fishcakes warm with lemon wedges or tartar sauce.

Tips for Perfect Fishcakes

Use chilled mashed potatoes

Cold mashed potatoes help the fishcakes hold their shape better.

Don’t skip chilling

A short chill in the refrigerator prevents the cakes from falling apart during frying.

Cook on medium heat

Too much heat can burn the outside before the inside warms through.

Use a nonstick skillet

This helps achieve a beautiful golden crust.
