  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.

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.

I'm cooking my late dinner right now with this recipe. It smells amazing and I'm sure it will taste the same ! I always use bbc website and I'm never disappointed! !!!!

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.

Made this tonight. It was simple enough but nothing special. Rather salty. I prefer oaty prawn and fish gratins.

This recipe was very good, even the mother in law liked it and she is really hard to please, so did my husband and my kids, so its a winner for me, make sure you squeeze out all the water from the spinach though and I used leek instead of spring onion.

I halved the recipe for 2 of us but in retrospect I think keeping the topping ingredients the same as the recipe would have been better as not much sauce. Also I found it didn't bubble and become golden, but that might have been due to my old, slow oven! Still we both enjoyed it with green beans and new potatoes.

Made this last night... I would never have thought of putting these ingredients together, but my husband and my picky 3 year old loved it. (I used smoked river cobbler and natural yoghurt, by the way.) A really simple, family meal that will become a regular, I'm sure!

Fab recipe - loved it!

Really tasty recipe. I don't add nutmeg as I don't like it and use a little finely chopped onion instead of the spring onions (as I didn't have any when I made it the first time and it tasted fine).
A regular meal that I serve with some potatoes that I cook in the oven too (after microwaving first to give them a head start). A favourite.

Quick, easy, tasty! My 2 toddlers loved it as much as the adults. Reheated in microwave next day really well which I wasn't expecting.

I doubled it for a larger group, had to put it in a large metal pan, and had no problems. Used half smoked black cod and half rockfish (can't get smoked haddock where I live, and smoked cod is expensive). Loved the cod, didn't love the rockfish so if being economical again, would look for a different white fish substitute. Was enough smokey flavour with the cod proportions I used and the meal had everyone singing. Super easy for such an impressive meal.

Can this dish be frozen?

goodfoodteam's picture

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. 

deejayellie's picture

Thank you. It's a super recipe! A firm family favourite in our house. :-)

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.

goodfoodteam's picture

Yes, still use the lemon juice as well.
