Gochujang Roasted Chicken Traybake

Gochujang roasted chicken traybake takes the familiar ease of a one-pan roast and gives it a Korean-inspired, spicy-sweet edge. The gochujang glaze brings fermented chilli depth, soy adds savoury richness, honey helps the chicken skin turn sticky and browned, and sesame oil rounds everything out with a nutty finish. Sweet potato roasts until tender in the same tray, while broccoli is added later so it keeps some bite and picks up charred edges. Finished with spring onion and sesame seeds, it is a practical weeknight dinner with bold flavour, plenty of vegetables and minimal washing-up.

Why this recipe works

  • Sticky, savoury glaze: Gochujang, soy sauce, honey, garlic and toasted sesame oil create a balanced coating with heat, sweetness and deep umami.
  • Efficient traybake method: The sweet potato gets a head start before the chicken and broccoli are added, so each component finishes tender and well roasted.
  • Good contrast: Crisp-edged broccoli, soft sweet potato, sticky chicken skin and a final scatter of sesame seeds keep the traybake varied.

Get the most out of this recipe

Adjust the heat

  • For less heat: Reduce the gochujang slightly and balance the glaze with a little extra honey or sesame oil.
  • For more heat: Add extra gochujang to the glaze, keeping the soy and honey in balance so it stays glossy rather than harsh.

Texture tips

  • Encourage browning: Keep the chicken skin-side up and avoid crowding the tray so the skin can brown instead of steaming.
  • Add broccoli late: Broccoli only needs the final part of roasting; adding it too early can make it soft before the chicken is finished.

Ingredient notes

  • Use bone-in, skin-on thighs: They stay juicy during high-heat roasting and give the glaze enough time to become sticky and browned.
  • Cauliflower works well: Cauliflower can replace broccoli, but keep the florets a similar size so they roast evenly.

Make-ahead tips

  • Prep ahead: The sweet potato can be chopped and the glaze mixed in advance, then kept refrigerated until cooking.
  • Reheat thoroughly: Reheat leftovers on a baking tray at 200°C (390°F) until piping hot, which helps the chicken and vegetables regain some roasted texture.

  1. Heat the oven to 220°C (430°F). Peel the sweet potato and cut into 2.5 cm chunks, then put on a large baking tray.
  2. Drizzle the sweet potato with 1 tbsp of the toasted sesame oil and toss to coat. Roast for 15 minutes to give it a head start.
  3. Meanwhile, stir together the gochujang, soy sauce, honey, remaining 1 tbsp toasted sesame oil, and the garlic (finely grated or crushed). Add the chicken thighs and turn to coat well.
  4. Remove the tray from the oven and nestle the chicken thighs among the sweet potato, skin-side up. Spoon any remaining glaze over the chicken and roast for 20 minutes, until the skin is starting to brown.
  5. Cut the broccoli into florets and add to the tray, turning it through the pan juices. Roast for 10 to 12 minutes more, until the broccoli is tender with charred edges and the chicken is cooked through.
  6. Thinly slice the spring onion. Scatter over the traybake with the roasted sesame seeds, then serve straight away with the sticky juices spooned over.

Recipe notes

Tips

  • For the stickiest finish, spoon the glaze from the tray over the chicken once or twice during the final 10 minutes of roasting.
  • If you are serving anyone vulnerable, make sure the chicken is piping hot throughout with no pink at the bone and the juices run clear.

Substitutions

  • Replace honey with maple syrup for a slightly deeper sweetness.
  • Replace broccoli with cauliflower florets; add them at the same time and roast until tender and lightly browned.

Storage

  • Refrigerate up to 3 days
  • Cool, then refrigerate in an airtight container. Reheat on a baking tray at 200°C (390°F) for 12 to 15 minutes until piping hot, or microwave in short bursts, turning the chicken halfway through.
