In the time it would've taken me to make a sandwich for lunch today, I had this caramelised onion and brie tart on a plate in less than 20 minutes (including oven time). I had a heap of onions to use up and what better way to use them up then slow braising in the pan and caramelising with brown sugar and balsamic vinegar.
I only had brie because I stocked up on meat from my butcher on Sunday and he was selling these wedges for $2.50! I should've got a couple (lucky I didn't - not the best for my non existent waist line). I think any cheese would work well with the onions.
Caramelised onion & brie tart
- one sheet frozen puff pastry
- 2 onions, sliced
- 2 tbs extra virgin olive oil
- 2 tbs brown sugar
- 2 tbs balsamic vinegar
- sliced brie (or cheese of your choice)
- Preheat oven to 180 deg C (365 deg F) and line baking pan with parchment paper.
- Heat olive oil in pan on low to medium heat and add onions, browning slowly, ie don't allow to burn. Season with salt.
- Once onions have softened, add brown sugar and balsamic vinegar and fry onion for a further 5 to 10 minutes, until sauce has caramelised.
- Slice puff pastry into 4 pieces and place on baking tray.
- Spoon onions into centre of pastry, allowing an 'edge' around the pastry.
- Top with cheese and bake in the oven for approx 10 mins.
- Serve on top of a dressed green salad.
These are great for lunch or dinner or make smaller ones using a mini muffin pan to make pastry cups and fill with the onion mixture and cheese for entertaining.
