Method
1. Get started: Take the chicken out of the fridge 30 mins before cooking, to allow it to come to room temperature.
2. Peel and finely grate the garlic into a small bowl. Pick the rosemary and thyme leaves, finely chop them and add them to the garlic. Grate in the lemon zest. Add 1 tbsp Italian herb blend and a generous pinch of salt and pepper. Pour in 2 tbsp olive oil and stir well. This is your marinade.
3. Cooking indoors: Preheat your oven to 180°C/Fan 160°C/Gas 4. Place the spatchcock chicken in a large roasting tin, skin-side up. Rub the chicken all over with the garlic and herb marinade. Cover the tin with a layer of tin foil and scrunch at the sides to seal.
4. Slide the chicken into the oven and roast for 1 hr, basting from time to time. After 1 hr, remove the foil from the chicken and slide back into the oven for 15 mins to finish cooking and crisp up the skin.
5. To check if the chicken is cooked through, insert a skewer into the thickest part of the thigh. The juices should run clear. If it needs a little longer, return the chicken to the oven for 5-10 mins before checking again.
6. Transfer the cooked chicken to a plate or board, loosely cover with foil and rest for 20 mins.
7. Slice the zested lemon into wedges. Carve the chicken and serve it with the lemon wedges on the side.
