The Best Vegan Mushroom Garlic Alfredo with no nuts. Garlicky, Creamy, Amazing Vegan Fettuccine Alfredo. Nut-free, Easily Gluten-free, soy-free. 21 gm of protein per serving!
This Fettuccine Alfredo packs a flavor punch with the browned mushrooms, wine, herbs, and creamyness from cauliflower, potato and hemp seeds.
I have several nut-free alfredo options on the blog and this is an addition to the list. You can use Cauliflower Alfredo Lasagna, Pumpkin seed Alfredo or my garlic sauce with the mushroom mixture too.
Mushrooms add an amazing flavor. They are cooked to caramelize with onions then simmered with wine and vegan worcestershire sauce. The alfredo is blended up and added to simmer with the browning mushrooms, so the sauce picks up that caramelized flavor. Delicious, Smooth and amazing. Garnish with fresh basil and pepper flakes and serve.
This Alfredo is Easy, Creamy, Flavorful! If you make it, let me know in the comments how it turned out and do tag me on Instagram.

Hi Richa (:
Would this work with frozen cauliflower too? Would it make a significant difference, in your opinion?
Hi Richa!
Can this be made without the potato?
yes double the cauliflower and you may have to cook the sauce a little longer depending on how thick you like it as the potato acts somewhat as a thickener.
Ooops, forgot to rate!
Tthanks!
I’m the only vegan at home. My omnivorous Husband, 2 teens and 21yr old LOVED this the first time I made it. It is now part of our rotation and we are having it AGAIN tonight! Thank you for this!!!!
wow!! glad that you found a new favourite . Do leave a rating too if you wish
This is another great recipe. I had a bunch of locally picked chanterelles to use up, so I used a pound of them to double this recipe. Reduced them (with onions and garlic), then added some Better-Than-Bouillon vegetable stock and reduced that, then added some Chardonnay and reduced again until everything was beautifully caramelized. The red pepper flakes were a little too much for my wife; will probably halve those next time for her sake. But I loved it. For the Alfredo sauce I used soaked cashews (with their soaking water) and added maybe 1/2 tsp nutmeg (essential to Alfredo in my book). Had no cauliflower so just used a medium russet, microwaved in a cloth pouch and skinned. Absolutely delicious over fusilli and a steamed broccoli side. Another winner!
Delicious! Even the non-vegan family members loved it.
Richa my kids are happy to adopt you. 😂
Another awesome recipe. Thanks.
This was super yummy!!
Tthanks!
How long should I soak the cashews for?
15 mins inn hot water
I’ve been missing Alfredo sauce ever since I became lactose intolerant.
This sauce is amazing! I didn’t think a vegan version could be just as satisfying but it totally is!
It’s going to be on regular rotation from now on! Thank you for enlightening me 🙂
yay!
What can I use instead of the wine?
broth
Thanks!
