From start to finish, it is ready in about 1 hour and 15 minutes.
Ingredients
For the Chicken
- 1 whole chicken, about 1.6 to 1.8 kg
- 2 tbsp olive oil
- 1 tsp sea salt
- 1/2 tsp freshly ground black pepper
For the Herb Butter
- 75 g unsalted butter, softened
- 2 garlic cloves, finely grated
- 1 tbsp fresh thyme leaves
- 1 tbsp fresh parsley, finely chopped
- Finely grated zest of 1 lemon
For the Tray
- 1 lemon, halved
- 1 red onion, cut into wedges
- 2 sprigs fresh rosemary

How to Make James Martin Spatchcock Chicken
- Prepare the oven: Preheat the oven to 200°C or 180°C fan. Place a shelf in the middle of the oven so the chicken cooks evenly and the skin crisps properly.
- Spatchcock the chicken: Place the chicken breast-side down on a board. Using strong kitchen scissors, cut along both sides of the backbone and remove it. Turn the chicken over and press firmly on the breastbone to flatten.
- Make the herb butter: In a small bowl, mix the softened butter with garlic, thyme, parsley, and lemon zest until well combined.
- Season the chicken: Gently loosen the skin over the breasts and thighs. Spread most of the herb butter underneath the skin. Rub the remaining butter over the top, then season with salt and pepper.
- Arrange the tray: Place the lemon halves, onion wedges, and rosemary on a large roasting tray. Sit the chicken on top, skin-side up.
- Roast: Roast for 45 to 55 minutes until the skin is golden and crisp and the juices run clear when the thigh is pierced.
- Rest and serve: Remove from the oven and rest for 10 minutes before carving. This keeps the meat tender and juicy.
Tips
How do I get really crispy skin?
Make sure the chicken skin is dry before adding butter and seasoning. Cooking at a high temperature and keeping the chicken flat helps the skin crisp evenly.
Can I prepare the chicken ahead of time?
You can spatchcock and butter the chicken up to 12 hours ahead. Keep it covered in the fridge and bring it back to room temperature before roasting.
What if my chicken browns too quickly?
Loosely cover the chicken with foil for the last part of cooking if the skin is colouring faster than expected.
Serving Suggestions
- Roasted new potatoes with olive oil and sea salt

- A fresh green salad with lemon dressing
