About this recipe: Frozen prawns are a great standby and transform a modest amount of fish into a hearty dish. Serve with mash, peas and green beans for irresistible comfort food made easy. Delicious!
For haddock, use virtually any skinless, boneless fish: cod, coley, whiting, smoked haddock or salmon.
Or soften frozen cod steaks in the microwave for a few seconds, then cut them into chunks and distribute over the spinach.
Or use drained canned tuna or salmon instead of the fish or to replace the prawns (use the liquid from salmon in the sauce).
For spinach, use frozen mixed vegetables.
Instead of mashed potato, fresh pasta or couscous are great accompaniments.
To avoid grating and chopping, add 3-4 tbsp pesto to the sauce instead of the cheese and parsley.
Cut up a bundle of spring onions in one go, using scissors.
Bake and serve the gratin in individual ovenproof dishes to cut down on washing up – the cooking time will be the same.
I made this as my youngest loves prawns. I'm not a fish fan, but found the combination with the spinach really added something to the flavour. The cheese sauce topping added a nice sauciness and crunch too. Kids weren't as impressed as I'd hoped, but I enjoyed it which is huge praise for anything with fish. - 23 Sep 2008
Mmmmm! Yum!! Great dish, quick easy and kids loved it so gets a five star from me! Only thing is next time I might cook the spinach first as it was a bit watery at the bottom and I prefer to make a cheese sauce with normal flour rather than cornflour. Definitely a keeper though, thanks! - 04 Sep 2014
Altered ingredient amounts. Feeding 6, I increased the haddock and decreased the spinach slightly - but only because I had less in than the recipe requested. For my preference, I'd happily increase it again. - 23 Sep 2008
