  1. Heat oven to 200C/fan 180C/gas 6. Put the tomatoes onto a baking tray, rub with a little oil and some seasoning, then roast for 5 mins until the skins are starting to split. Add the fish to the tray, top with most of the lemon zest and some more seasoning, then drizzle with a little more oil. Roast for 8-10 mins until the fish flakes easily.

  2. Meanwhile, cook the beans in a pan of boiling water for 3 mins until just tender. Drain, then tip into a food processor with the rest of the oil, garlic, basil stalks, lemon juice and stock, then pulse to a thick, slightly rough purée. Season to taste.

  3. Divide the tomatoes and mash between two plates, top with the cod, then scatter with basil leaves and the remaining lemon zest to serve.

Overpoweringly lemony, and yet somehow bland. Other half politely requested I never make it again.

Easy to make and even tastier to eat. Made this for a mid-week meal and received positive feedback.

We have tried this with both cod and haddock and found it to be a great midweek meal. Super speedy but also very tasty. We added peas to the mash and served it with broccoli for a bit of extra greenery.

I am giving this a 5 star rating for simplicity and flavour. However, I did make a few tweaks. Firstly, I used Basa fillets instead of cod. Much tastier fish and I think more sustainable in any case? Personally I would choose Basa over cod or haddock any day. And then for the bean mash, I used a tin of borlotti beans, heated them with the stock, some petit pois and the garlic, then added the fresh basil and just roughly crushed rather than reducing to a mash. The result was a really delicious dish that I will certainly make again. (I think you could use whatever beans you like or happen to have available for this.)

The most delicious thing I have eaten in a long time! I did tweak a little by doubling the garlic & lemon juice but other than that it was just fabulous. So tasty and so healthy! Oh and Morrisons have just started selling frozen Edamame beans so even easier to find - I am going to stock up my freezer! Enjoy guys!

I find cod quite bland so use haddock instead. A nice meal but needs extra seasoning - juice the whole lemon, 3 cloves of garlic. Also nice with butter bean mash

I've made this a couple of times now and it never fails to satisfy. I do cheat a little though and add some oven chips which makes this a good hearty dinner. I've never found frozen soya beans but a tin of butter beans seem to work fine (have to remember to heat them up though!) Five stars.

The flavours are delicate rather than strong, but the combination with the tomatoes is great. I did add three times as much garlic to the mash and perhaps a bit with the fish would be good too. The lemon zest was definitely good with it. Very pretty on the plate. The reason for tomatoes on the vine is to stop them rolling around your baking tray!

Good basic recipe, especially if you think you're not sure what to do with fish. Lots of variations are possible. I did cod, smashed up some boiled potatoes and used a size bigger in tomatoes as I think cherry would have virtually dissolved in the oven. Followed previous suggestions of putting a little balsamic and sugar on the tomatoes as well as oil, salt and pepper. Didn't bother with lemon rind or garlic but would probably use garlic next time. Poured all juices over the meal. Easy and tasty!

I use fresh runner beans, which I steam to a light crunch and then put in the food processor with the rest of the ingredients. Absolutely amazing! Can put this sauce on chicken or steak, always good!
