Rinse and then pat the chicken dry. Place it in an ovenproof dish and add the onion, sweet potato, pepper, mushrooms and tomatoes. Spread evenly.

Drizzle oil over the chicken and vegetables and season with the salt and pepper, then toss to coat. Drizzle the maple syrup and sprinkle the thyme.

Roast at 400°c for about 1 hour, 15 minutes, until the chicken is cooked through.
