Feel free to omit the flour from the sauce and make it gluten free. The sauce will still be nice and luscious just not quite as thick.
The pasta stores well in the fridge for up to five days. The sauce can also be frozen on its own in lidded freezer proof containers for up to months. Thaw out in the refrigerator before reheating and thin with a splash of veggie stock if needed when reheating. Best to always cook the noodles fresh.
