Gently wash the mushrooms and dry them well before cutting into quarters. Place a very large pan (ideally you want to cook the mushrooms in one layer) onto the stove and turn the heat to medium. Add the oil and once hot, add the shallots and fry for 2 minutes before adding the. mushrooms. Cook on a high heat for 15 minutes until the mushrooms have browned and all the water evaporated.

Meanwhile, boil a large pan of water and season with salt. Once boiling, add the pasta and cook according to the pack instructions. Once the mushrooms are brown, add the chopped garlic. Cook for 1 minute and season well with salt and pepper. Stir through the porcini mushroom paste.

Put the egg yolk, grated parmesan and parsley in a bowl and whisk with a fork to combine. Once the pasta is cooked, drain, but reserve a splash of the cooking water. Add the cooked pasta and cooking water to the mushrooms before stirring in the egg mix. Coat the pasta well before serving with more cheese on top.
