Kohlrabi and Spinach Gratin

Ingredients

1 tbsp sunflower oil
1 knob butter, plus a little more for greasing the dish
2 medium onions (about 600g), halved and finely sliced
Salt and freshly ground black pepper
500g kohlrabi, peeled and cut into 3mm thick rounds
250g potatoes, peeled and cut into 3mm rounds
2 tsp thyme leaves, chopped
200ml double cream
200ml water (or chicken or vegetable stock)
1 big handful baby spinach, or spinach mixed with kohlrabi leaves
1 tbsp parsley, chopped

For the topping

60g fresh breadcrumbs
25g butter, melted
45g cheddar or hard goat's cheese, grated

Directions

Preheat the oven to 190C/375F/gas mark 5. Place a medium-sized frying pan over a medium heat. Add the oil and butter, wait until it foams, then add the sliced onion and a pinch of salt, and sauté for 12 minutes, until soft and starting to take on a little colour.

Throw in the kohlrabi, potatoes and thyme, and season generously with salt and pepper. Cook, tossing the mixture occasionally, for another five minutes.

Pour over the cream and stock, simmer gently until the liquid is reduced by half, stir in the spinach and parsley, then place in a lightly buttered gratin dish, about 30cm x 20cm x 7cm in size, levelling it out with a spatula as you go. Place the gratin dish on a baking tray.

Blitz together the breadcrumbs, butter and cheese in a blender, and sprinkle over the top of the filling. Bake the gratin in a hot oven for about 35-40 minutes, until all golden and bubbling.

My favourite part is the beautiful and tasty veg! I feel good cooking fresh veg and the range of vegetables are great
