How To Make This Sauce

To make this delicious Vegan Cauliflower Alfredo Sauce, you want to start by boiling your cauliflower florets. I boiled mine for between 8 to 10 minutes until softened. Alternatively you can steam your cauliflower for approximately 15 minutes. 

The next step is to add all of your sauce ingredients to a blender. This includes the boiled cauliflower, nutritional yeast, a plant-milk of choice (like unsweetened almond, cashew, or soy milk), garlic powder, sea salt and lemon juice (or apple cider vinegar if you prefer). As you blend the sauce, add more liquid as needed to get a smooth consistency. I like to give mine a taste once blended to adjust the salt content as needed.

Finally, you want to add the sauce to a saucepan with your pasta of choice. I used whole wheat fettuccine, but chickpea pasta or another alternative would work great as well!


Enjoy served with freshly cracked pepper.
