  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.

DELICIOUS! Made with creme fraiche not cream. Used wholemeal breadcrumbs and added some dried parmesan on top. Skinned the haddock as my husband is fussy and he loved it! Anything that pleases him makes me happy, haha!

Absolutely loved this dish. We served it with Jacket potatoes and was lovely. I cooked it with half amount as only 2 of us but did the sauce mix the same quantity for 4 people which I'm glad we did or else it wouldn't have much sauce. A new family favourite.

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.

Thanks for your question. We're sorry to hear your topping curdled. Yes, this would be because you used single instead of double cream which can split when it gets too hot.

Really delicious and a new staple for us! Tomatoes added a surprising freshness. I would say though to definitely use dried breadcrumbs. Not thinking about it, I used fresh, and they went a bit soggy!

Can this dish be frozen?

Hi deejayellie, thanks for your question. We haven't tested freezing this recipe and it's likely that freezing it could result in a grainy unpleasant texture when defrosted, so would advise not doing so.

If i make this using either natural yoghurt or half-fat creme fraiche instead of the double cream - will it still need the lemon juice? Thanks.

Yes, still use the lemon juice as well.
