How to Make This Recipe
Step 1 – Prepare the Vegetables
Preheat your oven to 200°C (gas mark 6, fan 180°C). In a large roasting tray, combine the sweet potatoes, red onions, and unpeeled garlic cloves. Sprinkle the dried thyme and rosemary over the vegetables, season with salt and pepper, and drizzle with 1 tablespoon of olive oil. Toss everything together and spread the mixture evenly in the tray. Roast in the preheated oven for 15 minutes.
Step 2 – Add the Chicken
After 15 minutes, take the tray out of the oven. Give the vegetables a good mix, then add the chicken pieces to the tray. Drizzle the remaining olive oil over the chicken, squeeze the juice from one lemon over everything, and sprinkle the smoked paprika on top. Return the tray to the oven and roast for another 15 minutes.
Step 3 – Add the Broccoli
Once the chicken has been baking for 15 minutes, remove the tray again and add the broccoli florets. Pour most of the chicken stock over the vegetables and chicken. Place the tray back in the oven for an additional 15-20 minutes, or until the chicken is cooked through and the vegetables are tender. Once done, squeeze the soft garlic from their skins and serve with lemon wedges on the side.

Tips for Perfect Results
Here are some tips to ensure your traybake turns out great:
- Make sure to cut the vegetables to a similar size to ensure even cooking.
- Keep an eye on the chicken; it’s done when its juices run clear and it reaches an internal temperature of 75°C.
- Don’t overcrowd the roasting tray; if needed, use two trays to allow the ingredients to roast properly.
- Let your chicken rest for a few minutes before serving so it stays juicy.
What to Serve With This Recipe
