Mix the oil, paprika, garlic and lemon zest together with salt and pepper to create the marinade.
Brush over the Spatchcock Chicken and leave to chill in the fridge for 30 minutes.
Once the BBQ is ready, cook for 5 minutes on each side, then move to the edge of the BBQ and cook for a little while longer at the slightly cooler temperature. Be sure to regularly turn the chicken, basting in-between.
To check if the chicken is cooked, pierce between the thigh and breast with a sharp knife. The meat should be white and firm.
Once cooked, remove from the BBQ and leave to rest in foil for around 15 minutes.
Finally, drizzle with lemon and seasoning. Cut and serve.
