My son, Oliver found this recipe, made it and adored it. It’s rich but low calorie (ish) and very moreish.

Serves 6

6 tbsp butter
3 tbsp balsamic vinegar
1/2 cup honey
1/2 bunch fresh thyme
salt and freshly ground black pepper
4 red onions, quartered

Preheat the oven to 350F

Combine the butter, honey, thyme, salt and pepper in a small saucepan over medium heat.
Bring to a simmer and cook for 1 minute to reduce slightly.
Place the onions in a single layer in a baking pan.
Drizzle the butter/vinegar mixture over and roast until soft and slightly caramelized, about 45 to 60 mins (or more if necessary)
