This Vegan Fettuccine Alfredo is my go-to vegan pasta dish! I’ve been making this recipe for years but have never used actual measurements. Throw in some cashews, sautéed brown onions and garlic, lemon juice, miso paste, and salt. Blend and taste. Add something else. Blend again. Maybe add some basil to change it up or maybe a little nutritional yeast or vegan parm. Blend again and then it’s perfect! It’s the most delicious and decadent sauce and every time I make it I think “Write this down!!” This cashew Fettuccine Alfredo is so creamy, saucy and super easy!

What You Will Need For This Vegan Fettuccine Alfredo

Kitchen Essentials:

You’ll need a good quality blender for this cashew fettuccine alfredo sauce. If you have a vitamix or other high speed blender, use that! I use a nutribullet. If you don’t have a high speed blender, make sure you soak or boil the cashews! You sauce may not be as creamy but it will still be delicious.

Main Ingredients:

Cashews, become creamy and delicious when blended
Onion & Garlic, key to a delicious flavorful sauce
Lemon Juice & Dijon Mustard, acidity and balance
Black Pepper and Red Pepper Flakes, nice hint of spice and added flavor
White Miso Paste, umami

Substitutions:

Cashews: Cashews give this sauce that creamy texture and I personally haven’t been able to replicate the same flavor and texture without cashews. Instead of substituting this recipe, try my Roasted Cauliflower Alfredo for a delicious nut-free version.
Fettuccine Noodles: Use any pasta shape or gluten-free pasta.
White Miso Paste: Miso Paste is never optional to me. It adds a delicious flavor but if you don’t have it or want to buy it, leave it out. You may need to compensate and add more salt and maybe some nutritional yeast.

How To Make The Best Fettuccine Alfredo Every Time

Soften the cashews by soaking overnight or boiling for 20 minutes. This will ensure that the sauce is smooth and creamy.

As said above, you’ll need a good quality blender for this recipe. If you have a vitamix or other high speed blender, use that! I used my nutribullet but it over heated while I was blending and refused to turn back on. The sauce was still delicious and wonderful but just not as smooth. So it works and will work for this but a better quality high speed blender is preferred.

Taste and season to your preference. The written recipe is my preference in regards to acidity and saltiness but you may need a little more salt or lemon juice. ALSO, miso paste is very important in regards to flavor so if you don’t have it you will definitely need to add more salt or even some nutritional yeast to balance out the flavors. Again, blend and taste and adjust as needed.

FAQ:

My alfredo sauce is too liquid-y? What do I do?

Don’t panic! When you first add the sauce to the pasta it will seem like way too much. But let the sauce simmer with the noodles for a few minutes and you’ll have the most perfectly sauce coated fettuccine noodles.

What can I use instead of Cashews?

Cashews give this sauce that creamy texture and I personally haven’t been able to replicate the same flavor and texture without cashews. Instead of substituting this recipe try my Roasted Cauliflower Alfredo for a delicious nut-free version.

How long will Fettuccine Alfredo store in the fridge?

About 2-4 days. Keep in mind that noodles tend to soften and the sauce will dry up a bit when stored. Simply add a splash of plant milk to thin it back out or simply store the noodles and sauce separately.

Is this Vegan Fettuccine Alfredo freezer friendly?

Yes! Simply store the sauce and the noodles separately and freeze.
