    Horseradish root is larger than an ordinary radish, and has a hot, peppery flavour.



  1. Heat oven to 200C/180C fan/gas 6. Cook the potatoes and onion in boiling, salted water for 6-7 mins until almost tender. Drain well. Grease a 20 x 20cm baking dish with a little of the butter, then arrange the potatoes in it.

  2. Break the fish into chunky pieces, discarding any skin and bones. Tuck the pieces in and around the potatoes, then scatter over the dill. Whisk the cream, stock and horseradish together and season. Pour over the potatoes. Dot the remaining butter over the top, then bake for 20-25 mins until golden. Serve with a green salad, if you like.

I made this for the OH who said it was ‘alright’ - a bit samey in flavour and texture apparently. He loves smoked mackerel and potatoes so I thought this would be his dream dish. I didn’t follow the recipe faithfully as I was rushing so missed the onion and didn’t have any fish stock so maybe they’d have made all the difference. I suspect the kids will like it so will give it another try ‘to recipe’. Be warned, don’t try to fold the mackerel into the sauce as it’ll break up and you’ll get mackerel pâté.

Really quick and easy to make and just so tasty! Didn't have any dill and added grated cheese on top as suggested by others. Will definitely make again

Okay, made this again, with smoked, peppered mackerel this time. Still a simple and tasty dish. I do think the preparation time quoted is a bit unrealistic though. Peeling and chopping potatoes and peeling and slicing an onion, and then boiling them - all in 10 minutes? Not in my world! Also, for this one I used Morrisons "The Best" Creamed Horseradish and found it to be far too sweet. So clearly the brand of Horseradish makes a difference in this recipe. Still a great recipe though.

Great recipe. So simple to do and really tasty. The only changes I made were using hot smoked salmon instead of mackerel, and I used half potato and half celeriac. I found the Horseradish quantity to be just right. (I used Sainsburys Taste the Difference version). Definitely a recipe I will make again.

Oh, just to add I omitted the horseradish as I have never been a fan ... and the dish was just divine!

This is just GORGEOUS! A comforting, totally moreish and tasty meal. It's cheap too, and healthy with Omega 3 from the mackerel. I've made this 3 times so far, the latest being for 11 people and everyone LOVED it, and most had second helpings. My 3 year old and my 5 year old, having never had smoked fish before, asked for a little taste (it was their bedtime), and then asked for another taste with a resounding "Yum!" A meal that makes us all smile!

Just cooked this for my 16 month old as well as my husband and myself. Went down a storm. Agree it could do with a tad more sauce but still very tasty. Love that it is genuinely simple to make and economical but still lots of good flavours. Used creme Fraiche.

I expected the ingredients to be more 'melded' - I may try it again and cut the potatoes in slice - more like potato dauphinoise with mackerel in. Although it tasted nice, for all the faff & washing up, I think I'd have enjoyed mackerel with steamed potatoes just as much. First time I'd used horseradish in cooking, I used to think I didnt like it, but I will experiment with using it with potatoes again.

Really tasty recipe that has become one of our family favourites. It's economical and everyone loves it plus it's so quick and easy to make. I tend to reduce potatoes slightly and add a bit more mackerel, lovely when it's spread in a larger dish so the bits on top go a bit crispy.

Really nice - halved ingredients for two, but still made 3/4 of the sauce after reading comments. Used 1/2 fat crème fraiche and it was fine. Also added some mushrooms which I'd microwaved for 1.5 mins first so I could drain off the liquid before throwing them in, and put some grated cheese on top too. Lovely served with some tenderstem broccoli and my husband said it was a winner too! Definitely a "do again" recipe and easy-peasy for midweek meal.

All have been pleased with this dish. Best horseradish sauce is from Aldi. Adding anchovies or chopped coriander as a final garnish is a delicious add on.
