This is the best vegan fettuccini alfredo recipe you’ll ever make – bonus that it’s packed with fibre, protein and healthy fats!
Growing up, there were really only two types of pasta – red sauce and white sauce. I really would never turn my nose up at either of them (hello pasta, I love you for life), but there has always been something truly special and decadent about a good creamy fettuccini alfredo. As I get older, I realize it’s getting harder for me to have a ton of super rich cream based pastas on the regular – hence why I’ve taken to lightening them up and making them plant based when I can. This vegan fettuccini alfredo is rich, creamy, “cheesy” and yet totally non dairy, a healthier lighter version of the classic Italian staple.
Key Ingredients for Vegan Fettuccini Alfredo
Aromatics – You know, that means garlic and onions sauteed in a little olive oil. We just cannot make any Italian dish without that.
Soaked cashews– Soaking your cashews gives this dish it’s luscious creamy consistency. I recommend soaking them overnight to make it easy but if you’re in a pinch, see my note below on how to quickly soak them.
Fortified nutritional yeast – Nutritional yeast gives this vegan alfredo sauce a cheesy flavour but without any dairy or cheese! It’s also a great source of protein and vitamin B12 if you go with the fortified version.
Unsweetened oat milk – Any non dairy milk will work here but i do prefer a thicker one like oat or soy to almond which I find a bit watery.
Lemon juice – This just helps cut the sweetness of the cashew cream and bring a little zip to the alfredo sauce.
Chickpea fettuccini- Don’t feel limited by the fact that we call this fettuccini alfredo. If you have linguine, macaroni, spaghetti, whatever – use what you like and have. I love chickpea pasta for the extra protein but feel free to use whole wheat, regular, gluten free – whatever you’ve got!

FAQ about this recipe
Here are some commonly asked questions about this recipe.
Is this alfredo sauce gluten free?
This sauce is naturally gluten free! If you want to ensure the whole dish is gluten free, just be sure to use gluten free pasta.
Can i use whole wheat pasta?
Absolutely, you can use whatever kind of pasta you have on hand that you and your family like.
can i use zoodles to make this recipe really low carb?
You bet! I do recommend following the instructions here to ensure you get the moisture out of the zoodles so they don’t make the sauce super watery.
how can i quickly soak cashews if I didn’t do it the night before?
You can put your cashews in a small pot and cover them with water. Bring the water to a boil, cover and remove from the heat. Allow it to sit for 15-20 minutes, then drain and use!
Can i make this sauce ahead of time and how long will it last?
You can make the vegan alfredo sauce up to 3 days ahead and store it in the fridge. When you’re ready to make pasta, keep about a cup of the pasta cooking liquid and set it aside. Then heat the sauce up in a saucepan, add your cooked pasta and if your sauce is too thick, add a little of the pasta cooking water to thin it out.
