Roast Chicken, Brussels Sprout & Sweet Potato Traybake

One-tray roast chicken with caramelised Brussels sprouts and sweet potato

Brussels sprouts are having their moment in Victorian markets right now, and roasting is what finally wins people over — the cut edges caramelise and turn nutty instead of sulphurous. Everything goes into one tray with mustard and lemon, and dinner more or less looks after itself.

Ingredients

  • 500 g chicken breast, cut into large chunks
  • 400 g Brussels sprouts, trimmed and halved
  • 400 g sweet potato (about 3 medium), cut into 2 cm cubes
  • 1 red onion (about 110 g), cut into wedges
  • 3 garlic cloves, thinly sliced
  • 2 tbsp olive oil
  • 1 tbsp wholegrain mustard (check the label if you need it gluten-free)
  • Juice of 1 lemon
  • 1 tsp dried oregano
  • 1/2 tsp smoked paprika
  • Salt and freshly ground black pepper

Method

  1. Heat the oven to 200°C (180°C fan) and line a large roasting tray.
  2. Whisk the olive oil, mustard, lemon juice, oregano, smoked paprika, salt and pepper together in a large bowl.
  3. Add the sweet potato, sprouts, onion and garlic. Toss well, then tip onto the tray and spread out in a single layer — crowding is what stops things browning.
  4. Roast for 15 minutes.
  5. Toss the chicken through whatever dressing is left in the bowl, nestle the pieces among the vegetables and roast for a further 20–25 minutes, turning once, until the chicken is cooked through and the sprouts are deeply caramelised at their cut edges.
  6. Rest for 5 minutes, then squeeze over a little more lemon if you like and serve straight from the tray.
