Prep time: 10 minutes

Cook time: 45 minutes

Total time: 55 minutes

Servings: 6


4 Onions (thinly sliced)

4 Garlic cloves (chopped)

3 sprig Thyme

2 Bay leaves

850 ml Vegetable stock

300 ml white wine

1 tbsp Soy sauce

450 g Short pasta

200 ml Single cream / Vegan cream

100 g Goats cheese (grated) / Vegan cheese

2 tbsp Olive oil

1 tbsp Butter / Vegan butter

Salt & pepper


  1. Caramelise the onions: In a large ovenproof pan, melt the butter with olive oil. Add the onions and cook over medium-high heat, stirring often, for 10 minutes, until softened. Add the thyme, garlic, bay leaves, and continue to cook for another 10 minutes until the onions are deeply caramelised. Season with salt and pepper.
  2. Cook the pasta: Preheat the oven to 200C/180 fan/6 gas mark. Add the wine, stock, soy sauce, stock, single cream and the pasta. Bring the mixture to a boil and cover the pan to create steam. Stir frequently until the pasta is al dente and the stock has been absorbed, about 8-10 minutes. Remove from the heat.
  3. Bake the pasta: If needed (if you are not using an ovenproof pan), transfer the pasta to a large baking dish. Top with the grated cheese, and bake for 15-20 minutes, or until the cheese has melted and is lightly browned on top.
