Ingredients and substitutions

Instead of using butter and parmesan cheese like traditional alfredo sauces do, this dairy-free alfredo sauce calls for cauliflower and cashews that have been soaked and blended. The cashews give this sauce its creamy consistency and the cauliflower adds body and nutritional value. This sauce is perfect for tricking picky kids into eating some extra vegetables.

A little nutmeg and garlic give this cashew pasta sauce plenty of flavor. If you don’t have any fresh garlic then you can substitute one teaspoon of jarred chopped garlic or garlic powder. And you can omit the nutmeg if necessary.

This recipe calls for cooked cauliflower. I usually just throw some chopped cauliflower on a baking tray, sprinkle a little bit of water on it (to prevent the cauliflower from browning) and bake for 40 minutes at 350 degrees Fahrenheit. Alternatively you can boil or steam the cauliflower until it’s fork tender.

What to serve with this

I love tossing this sauce with fettuccini noodles and garnishing it with some finely chopped fresh parsley. Fresh basil or chives would make a delicious garnish too.

This sauce would also be delicious as a sauce for a white pizza, topped with some spinach and vegan cheese. Or make a white vegan lasagna using this alfredo sauce instead of tomato sauce.

Or for a lower carb option, roast some cauliflower and toss it with this cashew pasta sauce for a truly decadent cauliflower dish.


Store this cashew pasta sauce in an airtight container in the fridge for up to three days.
