Preheat the oven to 200° C.
Prepare the Celeriac by peeling and chopping in half. I suggest using a large, sharp knife to cut the bottom to create a flat surface and then carefully peel the outside layer of the celeriac with the knife.
Take one half of the celeriac and carefully peel into short ribbons using a vegetable peeler. It doesn’t matter if the sizes are not even.
Take the other half of the celeriac and carefully chop into 1cm cubes, toss these in 1-2 tablespoons of olive oil, the celery salt, nutmeg, dried oregano and some salt and ground pepper. Once evenly coated, place on a baking tray or oven dish and place into the hot oven.
Heat some oil in a frying pan on medium – high and add the diced onion until starting to brown.
Whilst the onion is frying, heat a large saucepan with 2 tablespoons of olive oil and then add in the flour and stir to create a paste. Add the milk to the saucepan and leave to simmer, stirring regularly.
Dice the leek and add this to the simmering saucepan along with a handful of freshly chopped coriander stems, finely chopped tomatoes and a generous seasoning of salt and ground pepper
Once the onions have started to brown, chop add the red pepper to the frying pan along with the crushed garlic.
In another saucepan place the celeriac ribbons in some water and bring it to the boil. Wait for these to soften slightly –approximately 3-5 minutes in boiling water.
Whilst the celeriac is softening, take a few tablespoons of the celeriac water and add to the frying pan, along with the spinach.
Once the ribbons are softened, drain them over a jug so that you can collect the celeriac water.
Add some of the water to the frying pan – you will want just enough so that the vegetables are covered and leave to sizzle for 2-3 minutes.
Whilst sizzling, place the ribbons back in the saucepan and back on the hot hob or on low heat so that they can steam dry.
Add the celeriac ribbons to the frying pan and then cover with the vegetable sauce from the saucepan and mix gently. Season with a pinch of celery salt and a large handful of finely chopped coriander.
Finely grate the hard cheese and add ⅔ to the pan and leave the mixture to simmer for 20-25 minutes.
Once the roasted celeriac is crispy on the outside, remove from the oven and serve on top of the celeriac mixture.
Sprinkle over the rest of the goats cheese and garnish with the finely chopped spring onions and pine nuts.
