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.

I literally eat this once or twice a week it’s so good. I also have to double the recipe because I’ll eat it all so fast
This was great!! Thanks for sharing 😊😋
This looks so gorgeous and creamy and comforting. I can’t wait to try it.
So, so, so good! I used cashew nuts, extra nutritional yeast and spaghetti in place of fettuccine. I also added a little dill and veggie ‘chicken’. Delicious. My 12 year old son gave it a 10 out of 10 and had a second helping. Definitely a keeper.
yay!
Wow this recipe is really, really good. I love the use of potato in this. And the thyme and kick of red pepper totally brings this recipe together. I used sliced gardein scallopini instead of the shrooms and added peas. I couldnt stop eating it! Loved this.
This looks & sounds incredibly delicious!

This was nice and creamy. I’m always looking for ways to make cauliflower, since it is healthy but I don’t care for it. Here’s my pingback: https://tmifood.wordpress.com/2017/10/19/creamy-vegan-pasta-with-mushrooms/
I searched vegan diwali and found a lot more than I imagined I would. THANK YOU!
What do you suggest in place of cashews and in place of potato?
pepita seeds or other nuts in place of cashews, more cauliflower in place of potato.
Hi Richa,
Thank you so much for the recipe! I added brocollini and it came out delicious 🙂 I was hoping to get your thoughts on freezing the sauce; I made way too much to eat myself!
I just got ready to make this a realized that someone must’ve gotten into my dry white wine while we had guests over last night!! haha
What would be the best substitute? I read a few substitute options but was curious to know which would be best for this specific recipe?
Omit it or use a bit of mirin.
