Sprouts, red onion and blue cheese gratin

Side Serves 4 1h
A quick and simple vegetarian gratin of whole Brussels sprouts nestled among sweet red onions and topped with melting blue cheese and crunchy breadcrumbs. Add a handful of cooked bacon lardons to this if you like. It's really good with roast beef.


  • 500g Brussels sprouts, trimmed and outer leaves removed
  • 2 red onions cut lengthways into 6-8 wedges with the root intact
  • a few thyme sprigs
  • olive oil
  • 100g blue cheese eg. Cropwell Bishop Stilton
  • 25g dried breadcrumbs (ideally panko for added crunch)
  • salt and pepper


Prep time: 10 min
Cooking time: 50 min
  • Step 1

    Preheat oven to 190°C/Gas 5. Toss the onions in a baking dish with the thyme sprigs and just enough oil to coat. Season. Roast for 15 minutes.
  • Step 2

    Meanwhile, bring a pan of water to the boil. Add the sprouts and cook for 4 minutes. Drain, then toss with the onions. Roast for 15-20 minutes, until the sprouts are just starting to crisp up a little.
  • Step 3

    Crumble over the blue cheese and sprinkle with the breadcrumbs. Roast for 10-15 minutes, until the breadcrumbs are golden.
