Place the halved Brussels sprouts into a medium bowl and drizzle with the oil, balsamic vinegar and brown sugar, sprinkle with salt and pepper then toss to combine and the Brussels sprouts are thoroughly coated.
Tip the Brussel Sprouts onto the lined baking sheet and arrange them in an even layer.
Place in the preheated oven and roast for 18-20 minutes until tender and caramelised, rotating the pan halfway through to ensure even cooking.
Check for seasoning and serve immediately.
