For a winning meal, serve this Easy Vegan Alfredo Sauce topped on freshly-cooked pasta. It’ll be a surefire hit with a hungry crowd and will take you no time at all. Just 25 minutes! The base is made with cauliflower and cashews which creates an ultra-creamy and luxurious sauce (nut-free option available).
If you’re looking for a quick and easy meal with a gourmet flair, you’ve gotta make this sauce! It’s perfect for a romantic dinner or a busy weeknight meal.
I adapted this from my 30-Minute Vegan Fettuccine Alfredo which is made with potatoes and cashews as the creamy base. The cauliflower version is just as luxurious and delicious.
The cauliflower flavor is very subtle, but if you’re not a fan at all, you may want to make the potato-based version. You’ll love it!
HOW TO MAKE VEGAN ALFREDO SAUCE
(full ingredient amounts in recipe card below)
- Chop a medium-sized cauliflower head into florets.
- In a large pan/pot, sauté minced garlic in butter until lightly golden
- Add vegetable broth, cauliflower, and cashews. Bring to a low simmer and cover for 12-15 minutes or until cauliflower is fork tender.
- Add everything from the pan into a high-speed blender, along with soy milk, lemon juice, nutritional yeast, granulated onion, and salt. Blend on high until smooth and creamy. Taste for seasoning and add more if needed.
- If you don’t have a high-speed blender, the sauce may not get completely smooth. I would suggest cooking the cauliflower longer until it’s really soft (add a few splashes of broth if needed). You can also try pre-soaking the cashews in cool water for 1-2 hours before cooking (or overnight).
- The consistency of the sauce should be thick and creamy. If it seems thin, you can cook it down a few extra minutes on the stove to thicken up. If you want it extra thick, you can add a cornstarch slurry. Add 1-2 teaspoons of cornstarch to 1 tablespoon of water. Combine well before stirring into the sauce. Cook for a few minutes until it thickens.
THE BEST WAY TO USE ALFREDO SAUCE
Pour it on pasta! This yields enough sauce for 1 pound of pasta and It’s perfect with fettuccine noodles! If you decide to use this sauce for pasta, you can boil the water and cook the pasta while you are preparing the Alfredo sauce.
Drain the noodles and drizzle them with olive oil to prevent sticking. Add the noodles to the pan of sauce and gently combine. Top with fresh-cut parsley, crushed red pepper flakes, freshly cracked pepper, and Vegan Parmesan Cheese if desired.
CAN YOU FREEZE VEGAN ALFREDO SAUCE?
Yes, this sauce freezes really well. Just let it thaw out in the fridge overnight and heat it up in a saucepan over medium heat. I usually add a few splashes of vegetable broth to thin it out a bit. Stir often to prevent burning. It should take 3-5 minutes to heat throughout.
CAN THIS BE MADE NUT-FREE?
YES! Just add 1 1/2 tablespoons of Tapioca Starch/Flour to the blender (along with the soy milk, nutritional yeast, onion, and salt). After blending, return the mixture to the pan over medium heat. Cook for a few minutes until the sauce thickens up nicely.
