  1. Heat oven to 200C/180C fan/gas 6. Tip the spinach into a colander and sit it in the sink. Slowly pour a kettle of boiling water over the spinach to wilt it, then run under colder water, squeeze out as much water as you can and set aside.

Cover the dish with foil and bake for 30 mins. Remove the foil, toss the celeriac around, cover again and put back in the oven for 30 mins.

  3. Remove the foil again, lay the fish on top and place a small knob of butter on each fillet. Cover with foil again and bake for a final 20 mins until the fish is cooked and the celeriac is tender. Scatter everything with chives and serve.

This is a family favourite, served with green beans. I only cook the haddock for 10 minutes. 20 is way too long

Wow. Loved this! I'm on a diet so I used single cream and left out the butter and it was still really nice. I also cooked the celariac for half an hour and then tossed through the spinach as I didn't want to cook it to death and loose all the vitamins. Cooked like that it was a tiny 5 Weight Watchers points! I served with a mountain of veg and some extra potatoes and it was a mountain of food and so healthy! Yum!

This was a lovely dish but the celeriac takes a very long time to cook! I cooked for 1.5 hours and it still wasn't quite soft enough for my taste. Goes really well with the smoked haddock. I agree with bluejay's comment below. To print one recipe currently takes approximately 3 sheets of paper. Let's have the old layout back - please ....................

Delicious! I sweated off a large leek in butter before adding to the spinach (used large bag) and celeriac and also mixed in a good grating of parmesan the first time it came out of the oven. Can't wait to have again!

Loved this! Have had disasters with celeriac gratins before so really left myself loads of time to make sure the celeriac was almost cooked before the fish went on. What a revelation! Raw, celeriac is great - but undercooked, it is a nightmare! Finally, I felt I had done it justice. I really recommend this.

Sounds lovely and I will definitely try it BUT please, please re-think the layout of your recipes and possibly reduce the size of the font so that the recipe can be printed on one side of A4 (in most cases). I know that I am not the only person to be irritated when you "updated" your perfectly good layout.

My gosh I can't tell you how delicious this is! The flavours work so well together and the consistency of the celeriac when sliced thinly like this is divine. I made a half quantity, but forgot to half the spinach, but would do the same again as it worked. I put a few spoonfuls of half fat creme fraiche I instead of double cream. Quick and easy but be sure to plan ahead as it's in the oven for a while.

Delicious recipe, really enjoyed using smoked fish as a main dish as well as the creamy celeriac. Only problem I had is the celeriac broke down fast as I had used a mandolin to slice it but that was my own fault!!

Quick, easy and delicious. What more could you want? Definitely one to cook again, and no tweaks to the recipe needed.
