Chop the butternut squash into 8 chunks and microwawe for 4-5 minutes to allow the skin to become softer and easy to remove. Allow to cool for a few moments.
Finely chop the onion and sauté in a pan with olive oil, salt and pepper.
Add the cubed butternut squash, herbs and spices and cook until tender.
Using a potato masher puré the pumpin mixture until it turns into a rough paste.
Add the vegan parmesan and allow to cool completely. If you're making the filling the day before, once cool cover with film and store it in the fridge.
To make the dough all we need to do is to combine both flour (sifted), the tumeric and incorporate the acquafaba. If it is too wet add some more flour, and if it's too dry a splash of water.
Work the dough until smooth, shape it into a ball and let it rest for at least 30 minutes.
After this time you will notice how much easier to work the dough has now became.
Now it's time to roll out the dough, both by hand using a rolling pin, or with the pasta machine. Make sure you roll it into very thin sheets before shaping the ravioli.
To shape the ravioli you can both use a ravioli mould or handmake them. Only make sure you seal the edges with few drops of water and to remove all the air before sealing.
Continue making the ravioli until you use up all the dough.
For the sauce simply heat the milk with a bunch of thyme. Reduce the heat and simmer for 5 minutes.
Combine flour and oil into a paste, then carefully add a splash of thyme infused milk at the time, to avoid lumps. Season with salt, pepper and nutmeg and put back on gentle heat until it thickens (3 to 5 minutes) stirring all the time. We are basically making a besciamelle sauce.
Cook the ravioli in plenty of salted boiling water (the time varies based upon the thickness of the pasta, from 2 to 5 mintes) then transfer into the white sauce pan. Make sure you save some of the cooking water to add if the white sauce results too thick. Cook it with the sauce for another couple of minutes, then sprinkle over some vegan parmesan, freshly grind numeg and fresh thyme, and serve.
