This tart tastes both sweet from the onions combined with salty from the cheese
Preheat the oven to 200C, 400F, Gas mark 6, Fan oven 180C
Ingredients
- 25g / 1oz butter
- 1/2 tbsp oil
- 2 large red onions finely sliced
- 1 tbsp sugar
- Pinch of salt
- 2 tbsp balsamic vinegar
- 1 Sheet puff pastry (thawed if bought frozen)
- 100g / 4oz feta crumbled
Finely slice the 2 large red onions
Heat the butter and butter in a pan and add the onions. Cook for a 2-3 minutes (you are not browning the onions you are softening them)
Add a pinch of salt, the sugar and balsamic vinegar, continues cooking for approx. 8-10 minutes until soft and caramelised.
The onion should be sticky not to wet, cook for a few minutes more if they are wet. Take off heat.

Un-roll the pastry and use to line a prepared baking tray (I use non-stick sheet)
Score (to score make a shallow cut, don't go all the way through the pastry) about 2.5cm/ 1inch all around the pastry, this will make walls of the tart.
Add the onion mixture evenly onto the pastry inside the lines you scored.
Crumble feta cheese and sprinkle over onion mix.
Bake for 15 minutes until the pastry has risen and is golden brown and the base is crisp. (Mine is a little over cooked, baking and talking on the phone is not a good idea!)
Cut into 4 and serve with a green salad.
