If you are looking for a decadent, easy vegan Alfredo sauce recipe, you have come to the right place!
Finding vegan fettuccine Alfredo at a restaurant is basically impossible, that is why I created this recipe for you to easily make it yourself at home!
The reason I love this vegan Alfredo sauce is because it is nut-free and gluten-free. You will agree this is the best creamy vegan sauce!
There are a lot of cashew Alfredo sauce recipes out there, and while they work great, not everyone’s tummies can handle nuts.
Some people are allergic. And some people just plain can’t afford to spend money on pricey cashews.
I want a creamy vegan fettuccine Alfredo dish to be accessible to everyone and that is why I created this recipe!
The secret ingredient here is cauliflower. Yes, you can buy it frozen from the store, but the key to a freaking amazing Alfredo sauce is to roast it low and slow for 30 minutes.
Yes, this makes the recipe take a bit longer to make, but it is so worth it when you taste the intensity of the flavor!
If you are short on time, you can simply steam the cauliflower until it is tender.
If you want to make this recipe oil-free, you can simply steam the cauliflower and veggies instead of baking it with oil.
You won’t get quite the depth of flavor baking it provides, but it is still tasty and creamy!
If you are feeding picky eaters, rest assured that this is a super kid-friendly vegan recipe! Who doesn’t like creamy pasta?!
If you have never made a vegan cream sauce using cauliflower, you are in for a real treat as it has a very neutral taste and is easier to digest than cashews.

Is Vegan Alfredo Sauce Healthier Than Regular Alfredo Sauce?
Ummm…that would be a resounding YES! Regular Alfredo sauce is loaded with butter, cream, milk, cheese [probably multiple kinds] and who knows what else!
While it may taste good, it is laden with tons of calories, fat, and dairy. Now, of course, if you aren’t vegan regular Alfredo may be good for a treat once in a while, but it surely isn’t healthy!
My nut-free Alfredo sauce recipe is loaded with the good stuff and high-quality ingredients!
Every single ingredient you put in you can pronounce and it is good for your heart and your health!
Cauliflower, garlic, onion, non-dairy milk and more. Everything is pure and simple and very good for you!
Vegan Alfredo Sauce Ingredients
- Cauliflower. Used for the base of the sauce.
- Garlic Cloves. These are essential for the classic Alfredo flavor.
- Onion. To add great flavor to the sauce.
- Oil. For roasting the vegetables and cooking them evenly.
- Salt. To add flavor to the vegetables.
- Non-Dairy Milk. You’re choice of non-dairy milk to make the sauce creamy. Water can be substituted.
- Lemon Juice. To add a hint of lemon flavor.
- Pepper. To taste for seasoning.
- Parsley and Basil. This is optional for a garnish.
How to Make Vegan Alfredo Pasta
I said it before and I will say it again!
Making this plant-based Alfredo sauce is so easy and healthy!
First, you are going to want to roast cauliflower, garlic, and onion for about 20-30 minutes until the cauliflower is tender.
This is an important step to giving the vegan Alfredo recipe a unique depth of flavor.
Again, since this isn’t a cashew Alfredo sauce, we want to give the cauliflower a little TLC for flavor!
If you are short on time or oil-free, you can simply steam your veggies until tender. This won’t taste quite the same, but if you are strictly oil-free, it is an easy modification.
Make sure to generously salt your veggies before roasting!
When making vegan sauce adjustments, using a lot of salt will help your recipe retain flavor.
I usually salt when cooking and then again to taste before serving. If something tastes “weird” it is probably because it hasn’t been salted enough!
Transfer your roasted veggies to a blender and add your non-dairy milk, lemon juice, and more salt.
Blend until smooth and adjust your salt to taste. If you want to throw in a little black pepper, now is the time!
And that is it! You’ve made your Alfredo vegan!
Top your pasta with the creamy vegan Alfredo sauce, and you are on your way to delighting your guests or your tummy with this yummy creation.
Believe it or not, the lemon juice and roasted garlic and onion are what add the punch and pizzazz to the vegan pasta Alfredo.
Although it does take about 20-30 minutes to roast the veggies, it only takes about 1 minute to puree it all together.
Don’t forget to top with fresh parsley or basil.
If you are feeling really fancy, you can make my Vegan Scallops Recipe and top your vegan fettuccine Alfredo with succulent vegan scallops.
You can even make my 3-Ingredient Vegan Gnocchi and toss the gnocchi in this Alfredo sauce for a truly decadent dinner.
Either way, you really can’t go wrong when making this recipe!
How To Store And Reheat The Vegan Alfredo
You can store the non-dairy Alfredo sauce in the fridge for about 3-4 days.
It may thicken in the fridge and that is okay!
To reheat, simply dump the remaining Alfredo sauce in a small saucepan and reconstitute with water or non-dairy milk until smooth.
Start by adding a little bit of milk or water at a time so that you don’t make the sauce too thin.
Once again, you will want to adjust the seasoning to taste!
This really is the best vegan fettuccine Alfredo recipe!
