Ingredients
- 25g butter
- 2 red onions, cut into wedges
- 700g Brussels sprouts (small ones if you can get them)
- 1 tbsp demerara sugar
- 2 tsp sherry vinegar
Instructions
- Step 1: Heat the butter in a large, heavy-based frying pan over medium heat. Add the red onion wedges and cook for 6-8 minutes, turning occasionally, until they are golden and caramelised.
- Step 2: While the onions cook, bring a pan of salted water to a boil. Add the Brussels sprouts and cook for 3-4 minutes until just tender. Drain the sprouts thoroughly.

Tips & Variations
- Choose small Brussels sprouts for a more tender texture and quicker cooking time.
- For added crunch, sprinkle toasted hazelnuts or walnuts over the finished dish.
- Substitute sherry vinegar with balsamic vinegar for a deeper, richer flavor.
- If you prefer a sweeter touch, increase the demerara sugar slightly, but be careful not to overpower the natural flavors.
Storage
Store leftovers in an airtight container in the refrigerator for up to 2 days. Reheat gently in a frying pan over low heat to preserve the texture, adding a splash of water if needed to loosen the glaze.
