How to make roasted Brussels sprouts
- Prepare the sprouts: Halve the Brussels sprouts (if they’re very small you can keep them whole) and place onto a large sheet pan or roasting dish. Drizzle with olive oil and season with salt and pepper.
- Roast: Place the pan in the oven and allow to roast for 30-45 minutes, turning the sprouts half-way through to ensure they roast evenly. You want them to caramelize and for the outer leaves to crisp up.
- Make the cheese sauce and crumbs: Make the cheese sauce according to recipe instructions (alternatively use store-bought cheese sauce if available). To make the crumbs, tear the bread into rough chunks and place on a sheet pan. Drape the prosciutto over the bread and add rosemary. Drizzle with olive oil and season with salt and pepper then place in the oven. Allow to roast until crisp and golden. Transfer to a food processor and blend until fine.
- Serve: Swirl the cheese sauce onto a large platter or bowl then top with the roasted brussels sprouts. Scatter over the crumbs and finish with fresh rosemary then serve.
Can I make this ahead?
All the elements can be prepared a day in advance and kept in the fridge. Reheat the brussels sprouts in a hot oven and the cheese sauce in a saucepan over medium heat before serving.
