  1. Heat oven to 180C/160C fan/gas 4. Place the spinach in a large colander in a sink and carefully and slowly pour over a kettleful of hot water to wilt it. Cool again under the cold tap then squeeze out as much liquid from the spinach as possible. Butter a medium gratin dish. Roughly chop the spinach and scatter evenly over the base of the dish. Season the spinach lightly with salt and pepper and lay the haddock fillets, skinned side down on top. Nestle the tomatoes among the haddock fillets.

  2. Mix all the ingredients for the topping, except the breadcrumbs, in a small bowl and season with lots of pepper and a little salt. Dollop and spread the mixture over the fish and spinach. Scatter everything with the breadcrumbs and bake for 30 mins until bubbling and golden. If you like things really grilled finish for a few mins under a hot grill. Serve straight from the dish.

Love this recipe. It has become a weekly staple in our house! I use frozen smoked haddock instead of fresh, I just cook it and drain out the liquid before adding all the other ingredients. I have made this with kale rather than spinach and actually prefer the flavour of the kale. Although the kale needs to be cooked rather than just wilted. As my husband is coeliac I leave out the breadcrumbs and top it with crushed up crisps instead :) a really gorgeous pie that goes perfectly with mash!

This is an excellent tasty recipie that all the family enjoy. I adapted it slightly by using the half fat version of creme fraiche and adding about half as much again of plain yogurt as I felt the quantity of the sauce was a bit on the low side. In my opinion, this gave a better amount of sauce for everyone as we are a bit greedy.I have also adapted this by using a couple of baked (well, microwaved!) potatoes which I cut into thick slices and used to layer the bottom of the dish first before putting on the spinach and other ingredients as suggested. This works well to provide a bit more ballast for hungry people. I use a good mature cheddar. I agree with other comments made about the tomatoes, they punch above their weight in this dish. One other thing I did was to remove the skin from the haddock before cooking.

This dish was absolutely delicious! I often use recipes from the internet but don't usually review them. However, I feel I have to reiterate other reviews and say how impressed I was with the ease of preparation and the final result, especially as my dish looked exactly the same as the picture, lol. Like a couple of other reviewers, I halved the tomatoes and my husband, who can take or leave tomatoes, commented on how they added to the overall taste. As fish lovers, we would have been more than happy to have been served this in a restaurant and I will certainly be making this again and again. Thank you.

Very tasty - however I would advise you not to add any salt. There's usually enough in the cheese and possibly the haddock.

Really tasty recipe. Didn't have any cream so used marscapone. Also used a mix of fish, smoked coley, salmon and hake. Worked really well and will definitely make again.

Really tasty recipe. Next time I will cut the little tomatoes in half & place them skin side up in the dish so the flavour gets to the rest of the ingredients. Nice & Easy family comfort dish. Will make it again. Thank you.

Great recipe for smoked haddock. I make it regularly. An easy family supper but it would stand up in any restaurant. I serve it over pasta - tagliatelle works very well.
