Creamy Vegan Mushroom Fettuccine Alfredo

Nope, vegan food isn’t all salads and smoothies. Plants can be transformed into wonderful things, you know.

…Such as this rich, creamy fettuccine Alfredo to satisfy your comfort food cravings, perhaps.

Though it’s on the healthier side when compared to the typical dairy-based version, cashews provide an amazing richness and ultra cream-factor to the sauce.

(Before I go on, I would like to apologize to all you nut-free readers. I promise a nut-free version is on the way! xx)

What I love about this cheezy vegan Alfredo sauce, is that it only requires 6 simple ingredients, a few minutes to whip up, and happens to be gluten-free as well!

By definition, Alfredo sauce describes “a rich pasta sauce made with butter, Parmesan cheese, and often cream”.

So, to create this purely from plant-foods, and still achieve a cheesy, velvety sauce, I used a mix of nutritional yeast + lemon juice (for cheesy-ness), cashews + almond bev. (for the cream-factor), and both salt and garlic powder to enhance and add flavor.

Then of course, you’ll need some fresh fettuccine pasta to accompany the sauce.

But first, to enhance the flavor of it all (and keep it from being plain old boring…), you gotta sauté some onions and mushrooms with garlic. This combo adds amazing flavors to the dish…and totally brings it to the next level 😉

Then, you can mix in the pasta & sauce.

To top it all off, I love a handful of fresh, chopped Italian parsley & vegan parm.

If you haven’t tried vegan parm yet, you must. It’s not my original idea/concept, but rather discovered from other vegan foodies. It’s a simple mix of cashews, nutritional yeast, salt, and garlic powder. (again, sorry nut-free folks…)

If you’re vegan, dairy-free, or simply open to trying somethin’ new, you gotta make this deliciousness.

I also think this would be the perfect dish for a potluck or gathering to show your friends how rich and flavorful vegan food can be made!

Not only is it 100% vegan, you can easily swap out the fettuccine pasta with a gluten-free pasta to have a full-on V/GF dish! Another perk? It takes just 20 minutes to make!

I sure hope you enjoy this dish as much as I did. If you try it, I’d love to know! Feel free to leave a comment, rate the recipe, or tag your photo @wholesomesoybean on Instagram so I can see.

Happy cooking, friends!! xx
