Leek, Mushroom & Gnocchi Gratin

1. Fill a large pan with water and add a pinch of salt. Pop the pan on a high heat and bring to the boil. Trim the roots and any woody greens off the leek, then rinse it under a cold tap to get rid of any grit. Chop the leek into 1cm-thick slices. Roughly chop or tear the mushrooms into small pieces. Slice the tender cavolo nero leaves from the thick stalks. Chop the leaves into small pieces. Peel and thinly slice the garlic cloves.

2. Pour 1 tbsp oil into a large ovenproof frying pan and warm over a medium heat. Slide the chopped leek and mushrooms into the pan and season with a good pinch of salt and pepper. Pop a lid on the pan. Fry the veg for 8-10 mins, stirring occasionally, till golden and juicy.

3. While the veg fry, warm your grill to high. When the water in the pan is boiling, carefully add the gnocchi to the pan and return the water to the boil. Cook the gnocchi till they float to the surface of the water – about 2-3 mins – then drain the gnocchi through a sieve held over a large bowl to collect the cooking water.

4. Keep an eye on the mushrooms and leek and when they are tender, add the cavolo nero and sliced garlic. Stir to combine and fry for a further 2-3 mins till aromatic. Pour in the soya cream and sprinkle with the nutritional yeast. Warm for 2-3 mins, till just bubbling.

5. Stir the gnocchi, veg and sauce together. If it seems too dry, add 1-2 tbsp water and stir. Keep adding water till you get the consistency that you want. Level the gnocchi and veg evenly with the back of a spoon.

6. Drizzle 1 tbsp oil over the top and slide the pan under the grill. Grill for 5-6 mins, till golden and bubbling. Divide the gnocchi gratin between warm plates and serve.

7. The Right Pan For The Job
If your frying pan isn’t suitable for putting under the grill, then transfer the veg, gnocchi and sauce to a snug heatproof dish before you slide under the grill (it make take a few more mins).

8. Love Your Leftovers
The gratin will keep for up to 3 days in the fridge in airtight tubs. Reheat in the microwave till piping hot.
