I halved this as a quick meal for one to use up a fillet of smoked haddock and it was fantastic!
Very quick, not watery after a quick squeeze of the spinach (though I wilted mine in the steamer whilst boiling some new potatoes to have with it so may be a little less wet??). Used cheddar as that's all I had. Was a bit worried could be dry but the creme fraiche sauce melted down perfectly.
Fantastic, tasty, quick - definitely a keeper!

Used English mustard as didn't have Dijon and also used slightly more breadcrumbs than suggested.
This was delicious. Absolutely loved this and was simple to do and quick to cook.
Cooked with roasted veg which although I love I wouldn't do again with this dish as it didn't really complement it. Will try a simple green salad to accompany which should work really well.

I used smoked cod lion as thats all I could find, very easy to make and soo tasty mmm! will be makig this again !

Delicious and quick. Used a mix of haddock, smoked haddock and prawns and cheddar instead of gruyere. After cooking spinach (2 mins in microwave - no need for butter) I squeezed all the at out and the meal was wasn't watery at all. Served with warm crusty bread. Will definitely make again.

Quick and delicious

delicious!

Made this today and was absolutley amazing. Stuck to the ingredients suggested but maybe next time add abit more spinach for personal preference

A total winner, amazing.
I've now made this several times, both as a main and as starters in individual ramekins, we all love it. If the fish or spinach give out too much water in the baking process, it's possible to press a large spoon or fish slice lightly on the top of the bake whilst tipping it gently to one side, so the excess liquid can pour into a saucepan. You can then reduce this liquid in the pan (the dish itself keeps nice and warm for ages) and then spoon the thickened sauce onto each ramekin or over the whole dish, depending what you're doing. Apart from the need to rectify the odd bit of watery-ness, this is just stunning and comes highly recommended! Simple but impressive - the perfect recipe, really.

Delicious! Used whole grain mustard, and half-fat cheddar. AMAZE!

Made this the other week, very yummy and a great way to eat more fish. I used a small lasagne dish to put everything in. Used powdered mustard and cheddar cheese. Made sure the spinach was well squeezed by hand and it worked well as didn't go runny. I added broccoli to the bake and served with crusty bread. Really easy all in one dinner. Would try with cauliflower and possibly cherry tomatoes next time.

Made this last night, lots of 'mmmmmm' sounds from everybody whilst eating. So quick and easy, I did squeeze the spinach but was still a bit watery but didn't take away from taste at all. I used mature cheddar and just doubled all ingredients apart from the spinach.

Definitely a 5 star recipe. So easy, so tasty and looks really impressive (in fact I'm going to do it for a dinner party in a couple of weeks). I found it needed blasting under the grill to get a crispy topping, but apart from that the recipe worked perfectly. The only thing I'd do differently would be to put a spoonful of the creme fraiche mixture underneath the fish to make the spinach creamy and cheesy too.

So easy and it tastes fab (I added more cheese). Best to squeeze spinach out with your hands.

Made this tonight for tea it was fab. I made it with smoked river cobbler instead of haddock and used grainy mustard, doubled the recipe and made it in one large dish it was very quick and tasty

Great and so easy - will definitely make again!!

I ended up cooking this for different guests 2 nights on the trot. Took advice from the comments and squeezed spinach with my hands. The second time I added more spinach than the recipe which I preferred. Also used 2/3 of the stock instead of the full amount.
Easy dish but impressive!

Made this recipe several times now - there's not many ingredients to it so it's best to get the best ingredients you can get, which includes gruyere instead of cheddar.
Apart from dietary issues I don't advocate boiling spinach anyway, so I let it wilt in some butter before sticking in the baking tray so no watery issues there.
I've also tried it with a mix of young and mature gruyere, but I prefer the mature flavour overrall.
Served well with salad, new potatoes and green beans.

Very tasty !

Great to have another recipe for Smoked haddock other than kedgiree or fish pie. Quick, easy and tasty. Gruyere was nice but I thought it was a bit pricey for a week day meal so will try an alternative next time.

What did you serve this with?
