    Olive oil

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

  • 2 large red onion, trimmed at the root and cut into thin wedges
  • 2 tbsp light muscovado sugar
  • 2 tbsp balsamic vinegar
    Balsamic vinegar

    Balsamic vinegar

    bal-sam-ick vin-ee-gah

    True Balsamic vinegar is an artisan product from Modena, in Emilia Romagna, Italy, and is made…

  • 375g sheet ready-rolled puff pastry
  • 100g feta cheese, crumbled
  • 175g black olive, pitted and chopped
  • 1 tbsp extra-virgin olive oil


  1. Heat oven to 220C/fan 200C/gas 7. Heat the oil in a frying pan, then gently fry the onions for about 10 mins until golden and soft. Add the sugar and balsamic vinegar, then cook for a further 5 mins until the juices are reduced and syrupy. Leave to cool.

  2. Unroll the puff pastry onto a baking tray. Score a line a finger-width in from the edge all the way around, then cover the middle with the onion mix. Scatter the feta and olives over. Season and drizzle the extra virgin olive oil over the topping.

  3. Bake for 15 mins or until the pastry is risen and golden and the base is crisp. Cut into wedges and serve with a green salad.

Worked out really well, great recipe? Good flavours, made one change which was adding mushrooms as not a fan of olives? Fried off the onions for 10 mins as said but threw the mushrooms in for last 4-5 mins of frying, good substitute for anyone who doesn't like olives :)

Went down really well for tonight's tea, I used a teaspoon of sugar for caramelising the onions as I thought a tablespoon was too much. I spread the base of the pastry with tomato purée before putting the onions etc on so the tart wasn't too dry. I also added fresh tomato and spinach to the tart in addition to the onions, feta and olives. Was really easy and would make again.

I also doubled the amount of onions and used goats cheese instead of feta, I think this works better. Very tasty!

I love this recipe, it's so simple and full of the flavours I love best. As everyone knows olives, feta and caramelised onions are a winning combination, and the balsamic adds that extra tang. Try adding some tomatoes and spinach to the mix if you want to change it up a bit, but the recipe really is great as it is. Alongside the salad, try serving with some new potatoes roasted with fresh thyme or rosemary. It's always a winner at home!

plus forgot to add that not enough onions to cover pastry either. so would use three large ones. Also onions didn't stay in wedges like the photo above! Same recipe but a different photo in the magazine.

YUK! too many olives - overpowering, tasted awful. Next time will only sprinkle a few halves.

Bit disapointed in this recipe. Next time will try mozzarella as this will melt unlike the feta. And will use less sugar next. I have a sweet tooth but not that sweet !

Have made this several times & it always get good comments. I left off the olives as we don't like them but don't think it matters there are lots of nice flavours!

Gonna try this with goats cheese for a main meal. Can't help thinking that walnuts would be nice on this? haven't got any so poss. next time :)

I've just cooked this but I made individual tarts for a party next week. They are delish! I think they'll go down well. I was a bit disapointed that the feta doesn't melt. Maybe next time I'll try goats cheese.

Made this as a starter and it was delicious! Will definitely make again, but agree that its not so good cold!

Really nice, my husband likes me to make the full 4 servings so that he can have the rest for his lunches!

Tasty recipe, but the onions were definitely not enough to cover my pastry. Next time, I'll add another one...or two!

Made this as a starter for a dinner party and it went down a storm! Left the olives off (as I dont like them) & didnt put sugar in, but would definitely make again, possibly adding sundried tomato or bacon? Yum!

After reading all the comments before I made this I adapted it slightly. I doubled the amount of onions, omitted the sugar as it was bound to be too sweet for me with that amount of sugar in it...but I did put in two teaspoons of redcurrant jelly. Caramalised the onions really well before putting them on the tart. Put some grated cheese on the pastry base before putting on the onions to help them stick. Didn't put olives on ...I love them but no-one else does so not worth putting them on just to be picked off!! Used feta but next time will use goats cheese as does need something sharpe to cut through the sweetness of the onions.

It was yummy. Went down really well. Tasty warm and cold. Definately make it again.

much better served warm than as a left over. If you make sure you get the onions really caremelised and sticky otherwise it's a bit dry.

Very nice, although I found it a bit too sickly for a main meal, and I used fewer olives. Would make it again, but definitely as a starter.

A big disappointment.

As the feta doesn't melt, it hardens, the ingredients didn't stick to the tart base, and so they fell off when the tart was was cut. I had even spread a thin layer of sundried tom paste to get them to stick, but obviously not enough.

I was also disappointed by the taste, too sugary and the feta doesn't take that away unless you use loads. I will use a strong goats cheese next time - it will break up the sugary taste, it will also melt to "stick" the ingredients to the base. I don't think I'll bother with the sugar either, all you need is the balsamic vinegar to caramalise the onions.

Not one of my favourites, I prefer my own creations to this one.

Absolutely fantastic recipe, and so easy to make. I used almost double the amount of caramelised onions for the tart as 2 onions didn't go far enough with the pastry. Also used fewer olives. As other people have said, perfect with a salad on the side--provides colour and crunch contrast next to the tart. Definitely committing this to memory and adding it to my repertoire!

So simple yet so delicious and it looks very attractive when served with a salad. My girlfriend, who loves feta cheese, was very impressed. Went down well with a glass of sauvignon blanc
