Boil the pasta in plenty of water until cooked al dente - approximately 12 minutes.

Meanwhile, melt the butter with the oil in a frying pan over a medium heat, and add the chopped onion. Cook for a few minutes, until slightly soft and fragrant, then add the mushrooms and the minced garlic. Cook for a further 5 minutes, until the mushrooms and onion are soft.

Next, add the white wine to the pan with the mushrooms, and raise the heat a little (medium-high), to bring the wine to a simmer. Crumble the stock cube into the liquid, allowing it to dissolve. Cook for a few minutes, in order to cook off the alcohol.

Turn the heat back down to medium-low, and stir in the cream. Add plenty of black pepper and most of the fresh parsley (save a little back for garnish), and mix to combine.
