Directions
Heat the stock in a medium saucepan over high heat.
Once it comes to a boil, add the cashews and garlic and let boil for 5 minutes.
Remove from the heat and let the cashews continue to soak for 30 minutes.
Pour the stock with the soaked cashews and garlic into a high-powered blender or food processor.
Add the almond milk, nutritional yeast, Worcestershire sauce, parsley, salt, and pepper, and blend until completely smooth and creamy.
Return the sauce mixture to the saucepan and cook over medium heat, stirring frequently, for about 5 minutes to allow the flavors to meld. If the sauce is too thick, add additional stock, one tablespoon at a time, until your desired consistency is reached.
Serve immediately or store leftovers in an airtight container in the refrigerator for up to a week. The sauce can also be frozen for up to 3 months.
Stir in a tablespoon of lemon juice at the end for a bright, zesty finish, or add a pinch of nutmeg for a more traditional Alfredo flavor profile.
