Instructions

Roast the Chicken
1

a) Preheat your oven to 240°C/220°C fan/gas mark 9. Boil a full kettle.

b) Heat a drizzle of oil in a frying pan on high heat. Once hot, lay in the chicken, skin-side down. Season with salt and pepper. Fry until golden, 3-4 mins, then turn and cook for 1 min on the other side.

c) Transfer the chicken to a baking tray, skin-side up, sprinkle over the dried rosemary, then roast on the top shelf of your oven until cooked, 10-12 mins. Set the pan aside. IMPORTANT: Wash your hands and equipment after handling raw chicken and its packaging. It's cooked when no longer pink in the middle.

Potato Time
2

a) Meanwhile, fill a large saucepan with boiling water from your kettle and return to the boil with ½ tsp salt.

b) Chop the potatoes into 2cm chunks (no need to peel) and add to the pan.

c) Cook until tender, 12-15 mins. Add the peas and cook for 1 min more. 

d) Drain well in a colander and return to the pan, off the heat. Cover with the lid to keep warm.

Chop and Grate
3

a) While the potatoes cook, trim the root and dark green leafy part from the leek and discard. Halve lengthways, then thinly slice.

b) Peel and grate the garlic (or use a garlic press).

Make your Leek Sauce
4

a) Return the (now empty) frying pan to medium heat. Add a drizzle of oil if the pan is dry.

b) Once hot, add the leek and season with salt and pepper. Cook the leek until softened, 4-6 mins, stirring occasionally. Add the garlic and fry for 1 min more.

c) Stir in the water for the sauce (see pantry for amount) and chicken stock paste. Bring to the boil and simmer until slightly reduced, 2 mins.

d) Mix in the creme fraiche, season to taste with pepper, then remove from the heat.

Finish Up
5

a) When the chicken is almost cooked, gently reheat the sauce. Add a splash of water if it's a little thick.

b) Season the cooked peas and potatoes with salt and pepper. Add the butter (see pantry for amount) and stir to combine.

Serve
6

a) Cut the chicken widthways into 2cm thick slices, then transfer to your plates.

b) Serve the peas and potatoes alongside, then spoon the leek sauce over the chicken.
