  • 2 tbsp flour

  • 1 lemon juiced

  • 2 tsp honey

  • 2 tbsp butter or margarine

  • 2 smoked mackerel fillets

  4. Melt the butter in a large saucepan and add the leeks, cooking for about 5 mins over medium heat.
  5. Add flour and mix well, then add the milk slowly and when it is all in bring to boil, then reduce heat so it is simmering for 5 mins or so.
  6. Add honey and salt and pepper and cheese and mix in thoroughly.
  7. Then add the fish and allow to cook for 5-10 mins on low heat.
  8. Then layer this mixture with the lasagne sheets in a large dish, cook at about 180C for 30 mins. Voila, seafood lasagne!

    This is delicious! My DC (3y & 10m)wolfed it down. I too left out the honey, and added a bit of melted soft cheese and grated cheese to the top layer. We'll definitely have it again. Actually I made the full quantity and froze half - there was just enough for two adults and two little ones.

    Fab recipe - made it for super-fussy inlaws and they wolfed it down. Only changes I made were to use half parmasan and half cheddar and I skipped the honey cause I didn't have any in. Will def be cooking this again and again and again!

    I love this recipe - you can use literally any kind of fish - as long as you have one bit of smoked in there, either haddock or mackerel. Or of course if your children don't like smoked fish you can skip that. I liked the fact that you only used one pan (plus the dish) and quite a lot of it could be done in advance, so it's great for a lunch or dinner party - once it's in the oven you can relax. And because it's so filling/tasty, you can just serve it with a salad. If you want to sneak extra veg in, frozen peas work quite well, though possibly best to boil them for a minute or so before adding.

    the recipe sounds complicated, but really all you are doing is making a cheese sauce and adding leeks and fish to it! It always seems to impress the people I serve it to which is why I often make it for guests..
