Method

  1. Heat oven to 200C/180 fan/gas 6. Boil the potatoes for 15-20 mins until tender, then drain. Reserve 3 tbsp corn and blitz the rest (with its juice) using a hand blender or a food processor until completely smooth, then mash into the potatoes. Cook the spinach following pack instructions – if you have a microwave, choose this method.

  2. Put the leeks in a pan with the 300ml milk and the butter. Cook gently, part-covered, for 8 mins until the leeks are tender. (Keep an eye on things as milk can easily boil over.) Mix the 3 tbsp milk with the flour and mustard, then stir into the leek mixture – keep stirring until thickened. Take off the heat and stir in three-quarters of the cheese.

  3. Squeeze as much liquid as you can from the spinach, then arrange on the base of 2 gratin dishes. Place a fish fillet on top of each, then spoon over the leek & cheese sauce. Top with the sweetcorn mash. Mix the remaining corn and cheese, and scatter on top. Place the dishes on a baking tray and cook for 25 mins until the fish flakes when tested and the top is golden.

10 mins prep is way under. It took me 40. Even if you're fast, unlike me, allow 25 min

My partner gave this 9 out of 10 so it must have been good! Recipes on here rarely get that high a mark. I made it in one largish baking dish and didn't bother pre-cooking the spinach (why would you when it goes in the oven for 25 mins?!) Also used a lot more (full fat, mature) cheddar and served with green beans and peas. I rated it 5 out of 5 and am sure to make again Best to use the best quality sweetcorn - jolly green giant, for the most flavour IMHO.

Made this to the recipe for hubby and I, children were most put out, we had to share some out. All loved it, so will double up and make in 1 bigger dish, rather than individual dishes. Disagree with comments on sweetcorn mash, it was lovely...!

I've made this a couple of times now, the first time followed it to the letter. We didn't like the sweetcorn mash, it had a funny texture and colour and we didn't feel it added anything to the dish. Second time made a basic white sauce and added cheese then stired it into the leeks which I sauteed in a little butter and just made ordinary mash and felt it was better. Also 2nd time used smoked haddock which was nice.

Hi, can you tell me what size gratin dishes you used for this? Want to make as it looks so delicious, but not sure what size to buy. Thanks.
