Bring Co-op to your front door

Big Bag Option


  • Co-op plain flour, for dusting
  • 375g pack ready rolled puff pastry
  • 4 onions
  • 2 tbsp Co-op olive oil
  • 100g Co-op Fairtrade light brown soft sugar
  • 3 tbsp Co-op cider vinegar
  • 3 tbsp Co-op ruby port
  • 1 tsp dried thyme
  • Thyme leaves, to serve (optional)


  1. Preheat the oven to 200°C/fan 180°C/Gas 6
  2. Dust the work surface with a little flour and roll the pastry out to a circle just bigger than 28cm diameter
  3. Cover in greaseproof paper and chill in the fridge
  4. Slice each onion into 3 or 4 thick rounds. Heat the oil in an ovenproof frying pan, 28cm across, then carefully arrange the slices in 1 layer and fry for 5-7 mins over a high heat, until golden and lightly charred
  5. Mix the sugar and vinegar together, pour around the onions and bubble over a high heat for 5-6 mins, until reduced and syrupy. Swirl through the port and thyme, then bubble for 1 more minute
  6. Take off the heat and allow to cool for 5 mins. Place the chilled pastry over the onions and tuck in around the edges
  7. Put the pan directly into the oven and cook for 25-30 mins, or until puffed up and golden brown. Once it’s cooked, turn the tart out onto a serving platter and cut into wedges
  8. Serve garnished with a few thyme leaves, if you like
