  • 600 g white fish fillets I use flathead, roughly chopped into large chunks
  • 1 teaspoon lemon rind finely zested
  • 1 tablespoon parsley finely chopped
  • 2 tablespoons Easy Keto Mayonnaise click link for recipe
  • 1/2 teaspoon celery salt
  • Salt and pepper to taste
  • 60 g golden flax meal
  • 60 g parmesan finely grated
  • 1/2 teaspoon cracked black pepper
  • 1 teaspoon Dijon mustard
  • 2 eggs
  • 1 tbsp olive oil for quick optional shallow fry
  • Lemon wedges to serve


  • Add fish, lemon rind, parsley, mayonnaise, celery salt, salt, and pepper to food processor. Pulse until mix comes together. (TMX 15 seconds/speed 6).
  • Shape mix into 4 large patties. (I use a large egg ring for this)
  • Transfer patties to a small plate and freeze for 30 minutes. (This helps for the crumbing process).
  • Preheat oven to 200 ̊Line a small baking tray with baking paper.
  • Combine flax meal, parmesan and black pepper in a small bowl.
  • In a separate bowl whisk together Dijon mustard and eggs.
  • Coat the fish cakes in the egg/mustard wash, then roll in the flax meal mix.
  • Bake for 15-20 minutes until golden and cooked through.
  • Fry in hot frypan for 1 minute each side to brown coating (optional)
  • Serve with a delicious salad or Low Carb Roll with Mayonnaise or Tartare Sauce.


  1. Fish Cakes can be made ahead and cooked when needed or kept frozen.
  2. Eat hot or cold.
  3. Use any fish or even prawns/shrimp for a tasty variation.
  4. For a dairy free version swap parmesan for nutritional yeast flakes.
  5. Almond meal can also be used in place of flax meal if you have a sensitivity to flax.
