Ingredients

    Probably the most widely-used oil in cooking, olive oil is pressed from fresh olives. It's…

  • 3 garlic clove, crushed
  • few thyme sprigs

    New potatoes have thin, wispy skins and a crisp, waxy texture. They are young potatoes and…

  • 2 red pepper, cut into large chunks
  • 1 red onion, cut into eighths
  • 1 green chilli, deseeded and chopped
  • 400g can cherry tomato

Method

  1. Heat oven to 220C/fan 200C/gas 7 and put in a roasting tin to heat up. Put the tuna in a shallow dish with half the oil, two-thirds of the garlic and leaves from 1 sprig of thyme. Leave to marinate while you cook the veg.

  2. Put the potatoes, peppers, onion and chilli into the roasting tin with the remaining oil, toss to coat, then roast for 20 mins. The potatoes should be tender or very nearly there. If not, give them another 5 mins (the cooking time can depend on the variety of potato). Add the remaining garlic and thyme to the pan, let them sizzle, stir in the tomatoes, then cook for 5 mins more until the sauce has reduced a little. Season to taste.

  3. With a few mins to go, heat a griddle or frying pan, wipe most of the garlic marinade off the fish with kitchen paper, season, then sear for 1 min each side for medium or longer if you prefer. Serve on top of the veg.

Really loved this dish, used a george foreman to grill the tuna. I didn't use thyme or chopped tomatoes with the potatoes but instead used a dash of soy with the red onions, red pepper, chilli and new potatoes and it all went really well together.

Very nice indeed, just made on spec, so hadn't bought in the ingredients, I happened to have almost everything I needed bar the fresh green chilli...just used some chilli flakes instead...lovely

We really liked this, tuna was a little bland though. Froze the left over veggies and had them with cajun salmon - even yummier! Will def make again. Dead easy too. Will add more spuds next time.

This recipe was soooooooooo goooooooooooood - it was a good dinner that was really light. I cooked the tuna for less than a minute each side for the thinner steaks because they have to remain pink in the middle to be at their most delicious! I didn't have any problems with the potatoes taking longer than anything - I followed the recipe exactly and everything turned out perfect! I think I added more thyme than the recipe said but that's about all i changed!

This was delicious......I used a combination of cherry tomatoes and a small tin of chopped tomatoes, added five mins from the end with the garlic, chilli & extra thyme. Would definitely do again.

This is a fantastic supper dish. Easy to make and delicious. parboiling is definitely the eay to go. Sainsbury's also sell cherry toms in tins. have made this loads of times already.

Asda sell tinned cherry toms too. I agree that method has several timing issues,potatoes definately need par boiling before roasting even when cut 1 cm or less. Finished dish was fab though

Really enjoyed this, particularly the marinated tuna. Parboiled the potatoes as recommended but the veg still took twice as long as suggested to roast till nice and soft. Would definitely make again. To the person who couldn't find them - they sell tinned cherry tomatoes in Waitrose.

This recipe was really lovely... although I did have to par boil the potatoes. I didn't add the chilli but instead used 1-2 tbsp balsamic vinegar to add more flavour to the sauce.
I would definately make this again.

Delicious. Really fresh tasting. I found the potatoes were cooked in the prescribed time - perhaps others overlooked the instruction to slice the potatoes into 1cm thick slices?

A very nice dish. I didn't have tinned cherry tomatoes so I used a combination of tinned chopped tomatoes and cherry tomatoes. Also used chilli flakes rather than fresh chilli. Enjoyed by all the family.

Hm. I'm interested in trying this recipe but having read the comments I'm a bit wary - am I the only one whose never come across a tin of cherry tomatoes? I keep looking around when I'm outand about and can't seem to see them

I forgot to buy a chilli, so instead I used a good slug of piri-piri sauce and it turned out great.

This was the first recipe I've tried from the good food website and it was delicious. I took heed of all the comments and made the necessary adjustments so thanks everyone!

really should have read the comments before trying to make this one - used the timings suggested and we were left waiting for the potatoes to cook for so long that we had eaten the rest of it before they were ready. Tasted really yummy still.

My first taste of fresh tuna, and it was good - although I slightly overcooked it! I also put the potatoes in about 15 minutes before the peppers, and the whole pepper/tomato/potato combination was really lovely.

Make with sweet potato instead of regular potatoes for an even sweeter addition to the salty tuna!
