Ingredients

Caramelized Onions

  • 2 large red onions Note 1
  • 2 tablespoons olive oil
  • ¼ teaspoon salt Note 2
  • 20 grams/1 tablespoon butter unsalted, Note 3
  • 2 tablespoons balsamic vinegar
  • 1 tablespoons brown sugar

Brie

  • 200 grams/ 7 oz wheel brie cheese Note 4

To serve

  • thyme
  • crackers

Instructions

  • Onions: use a knife and cutting board to peel the skin and then thinly slice your onions. Once done use your fingers to seperate the sliced onions into individual rings.
  • Cook: place a large sauce pan onto the stove top, add the olive oil and then turn the heat to high. Next add the onions and then let them cook using a wooden spoon to move them around in the pan for 8-10 minutes. After this time turn the heat to low, add the butter, balsamic vinegar and brown sugar. Stir to mix in and then let the onions cook and caramelize on the low heat for a further 15-20 minutes. Stir every now and then during this time.
  • Preheat the oven: preheat the oven to 180°C / 350-375°F / Gas Mark 4-5.
  • Brie: remove the packaging from the brie cheese and place it onto a silicon baking mat. Use a sharp knife to score the top rind in a diagonal pattern. Place it into the preheated oven and bake the brie for 7-8 minutes.
  • To serve: remove the baking tray from the oven and use a flat silicon turner slid under the brie to transfer it to a serving plate. Spread the caramelized onions over the top then add the thyme. Place a cheese knife on the plate and add firm crackers for serving.

Notes

  • Note 1 - Onions: you can use brown onions or a combination of red and brown onions ie 1 of each if you wish to. 
  • Note 2 - Salt: this can be omitted if you wish as the cheese does bring a salt component to the recipe. 
  • Note 3 - Butter: we want to use unsalted butter as a means to not add further additional salt to the recipe. 
  • Note 4 - Brie cheese: this is a standard size wheel of brie cheese. The recipe does lend itself to a wide range of sizes of wheels. The smaller the wheel, the more onions you will have on top.
