Cooking Instructions
Instructions for 2 people (double for 4)
1 Simple Chicken, Leek & Gnocchi Gratin

Preheat the oven to 200°C/ 180°C (fan)/ 395°F/ Gas 6

Heat a large, wide-based pan (preferably non-stick with a matching lid), with a drizzle of vegetable oil over a high heat

Once hot, add the chicken thighs with a pinch of salt and cook for 3-4 min or until starting to brown

2 Simple Chicken, Leek & Gnocchi Gratin

While the chicken is cooking, wash the leek[s] carefully to remove any grit from between the leaves, then top, tail and slice finely

3 Simple Chicken, Leek & Gnocchi Gratin

Add the sliced leek to the pan with the chicken and reduce the heat to medium-low

Cook, covered, for 10 min further or until the chicken is cooked through (no pink meat!) and the leek has softened

4 Simple Chicken, Leek & Gnocchi Gratin

Boil half a kettle

Combine the panko breadcrumbs with the dried basil, a drizzle of olive oil and a pinch of salt and pepper – this is your basil crumb

Dissolve 1/2 [1] Knorr chicken stock cube in 350ml [550ml] boiled water and add the Dijon mustard, soft cheese and a very generous grind of pepper – this is your stock

5 Simple Chicken, Leek & Gnocchi Gratin

Add the gnocchi to an oven-proof dish

6 Simple Chicken, Leek & Gnocchi Gratin

Once the chicken is cooked, add 1 tbsp [2 tbsp] flour to the pan and cook for 1 min, then gradually add the stock and cook for 1 min further

Transfer the cooked chicken to a clean board and shred it apart, using two forks - this technique is known as ‘pulling’

Return the pulled chicken to the pan and stir everything together – this is your creamy chicken mixture

7 Simple Chicken, Leek & Gnocchi Gratin

Top the gnocchi with the creamy chicken mixture and give everything a good mix up

Top with the basil crumb

Put the dish in the oven for 15-20 min or until the basil crumb is golden and crispy – this is your chicken, leek & gnocchi gratin
