Step 1

Heat the oven 220C/fan 200C/gas Season the chicken all over. Heat 2 tbsp of the oil in a large casserole over medium-high heat. Put the chicken in the pot, breast-side up and, using tongs, press lightly to make sure the skin comes into even contact with the base. (If using thighs or legs, sear the chicken skin-side down.)

Step 2

Cook for 5-8 minutes without moving the chicken, until browned. Add the lemon slices and shallots, ensuring the lemon gets to the bottom of the pan. Sizzle for 2 minutes.

Step 3

Add the dates, herbs and 250ml water. Sprinkle the top of the chicken with the chilli and put the lid on. Roast in the oven for 20-25 minutes or until the dates are plump, the lemon slices are jammy and the chicken is almost but not totally cooked through.

Step 4

Remove the lid and drizzle the chicken with the remaining 2 tbsp olive oil. Continue to cook for another 20-30 minutes or until the liquid has reduced by 1 /2, and the top of the chicken is golden brown.

Step 5

Let the chicken rest in the pan for 10 minutes, then transfer to a chopping board and carve. Serve alongside the shallots, lemon slices and dates, with some more thyme and flaky salt sprinkled over.
