Until you try it, you may have a hard time believing that an alfredo sauce made almost entirely from cauliflower can be as rich and decadent as it is.

Typically a traditional alfredo sauce gets its rich and creamy velvety texture from a combination of heavy cream, butter, and cheese. This particular version gets its creaminess simply from cauliflower and its mind blowing.Don’t believe me? Just try it!

This Easy Vegan Mushroom Alfredo is perfect served over any noodle of your choice. I used fusilli which I happened to have on hand, but it’s also delicious served over spaghetti squash or zoodles which is simply spiralized zucchini for a gluten-free low-carb option.
