FAQ

Can I use other pasta shapes instead of spaghetti?

Yes, but cooking time may vary. Short shapes like penne work well, while long shapes need a wide pan to fit properly.

What if I don't have white miso?

You can omit it or substitute with extra nutritional yeast and a pinch of soy sauce for umami depth.

How long will leftovers keep in the refrigerator?

Store covered for up to 3 days. Reheat gently with a splash of plant milk to restore creaminess.
