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.

Oh my goodness, this is so delicious. My husband and I both went back for seconds. I omitted the oil, used 1 tablespoon hemp seeds and about 2 tablespoons cashews to the potato/cauliflower sauce. Used fresh basil. Also doubled the amount of mushrooms because I love them. It was crazy good, and I’m going to use this when cooking for others who are not vegan because it tastes so decadent!! Thank you Richa😍

Yay, thank you!

I found a ton of their recipes on Pinterest and I was excited to try them so I’m using them in my whole meal plan this week I made this recipe for me one and it’s so good.
Vegan Richa Support
great to hear Kinsey =)

Yum! I don’t miss the dairy one bit!
Vegan Richa Support
Awesome – exactly
Dani
Hi! i’m curious… is the alternative to the worcestershire sauce a mix of those ingredients or should i sub for either of those??
Richa
Yes a mix of the ingredients
Kristen
This turned out SUPER yummy! It was pretty quick and easy too. My sauce was green – which is not as visually appealing as the photo that accompanies this recipe. . . I used hemp seeds and fresh basil so I think one of those did it. Still really delicious.
Vegan Richa Support
sounds yummy & healthy
Asma
Hi, I’ve used normal dried yeast as thought it was the same as nutritional yeast but the sauce smells a bit too yeasty. Is that normal?
Vegan Richa Support
they’re two very different products
Richa
Normal yeast is active and used for breads. Nutritional yeast is inactive and cheesy tasting. They r very different.
Terri Hartsfield
I made this tonight for dinner. I used the cashew option in the recipe and added some asparagus at the end. Otherwise the recipe was made as written and was fabulous! This will absolutely be one of our go-to dinners.
Vegan Richa Support
asparagus – tasty idea. thank you
Yvonne deGraaf
This was really good! I also added a cup or so of dried mushrooms and used the soaking water in the sauce instead of just water. Super yummy. Thanks!
Vegan Richa Support
perfect. thank you
Jacqueline
I have tried the recipe as yet, they looks very delicious. I can’t wait to try them

Thanks for this! Since we are gluten free, I’ll have to see if can find any good gluten free pastas that would work here! If so, great recipe for us to try!

Enjoy – thanks for popping in

Hi Richa (:
Would this work with frozen cauliflower too? Would it make a significant difference, in your opinion?
LC
Hi Richa!
Can this be made without the potato?
Vegan Richa Support
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!

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!!!!
Vegan Richa Support
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!
Elizabeth
Delicious! Even the non-vegan family members loved it.
Leena
Richa my kids are happy to adopt you. 😂
Another awesome recipe. Thanks.
Sandra
This was super yummy!!
Richa
Tthanks!

How long should I soak the cashews for?
Richa
15 mins inn hot water
Khary
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 🙂
Richa
yay!
Jessica
What can I use instead of the wine?
Richa
broth
Jessica Marie Shepherd
Thanks!
Lauren
I would love to make this but do not like mushrooms. Can I omit the mushrooms and the flavor of the recipe wouldn’t be lost?
Richa
yes omit them. taste when simmering and add more of the existing flavors if needed, like the soysauce, miso, garlic, herbs etc.
Michelle Burgoyne
what is considered a “small” potato. what weight do you usually use?
Richa
160 – 170 g or 1 3/4 to 2 inch size
Julie
I just made this recipe-WOW! My only regret is that I didn’t make it sooner! I will be making it on a regular basis. It was not complicated at all. It was so creamy and the mushrooms were amazing the way they caramelized. I didn’t have white wine, so I used red and it worked just fine! Thank you for sharing such amazing recipes! Keep it up!
Richa
yay!!
Ida Moser
HELLO Alfredo….where have you been ? Alfredo is one pasta recipe I’ve been missing since going vegan two years ago. This particular recipe blew me away. Totally satisfying and incredibly flavorful. I used half hemp and half soaked cashews and the sauce turned out perfectly yummy and perfectly creamy. I added about 1/4 cup of potato/cauliflower water to thin and I used more fresh basil than what the recipe called for (so slightly green) but the flavor was completely perfect. Thank YOU, Richa, for yet another incredible recipe!!!
BB
Looking forward to trying this recipe – do you have instructions for cooking in an Instant Pot by any chance?
Richa
they’ll be in my upcoming Instant Pot book.
Kristie
Out of habit I always serve sauce on the side for my kids so they can chose to add it to pasta after tasting it first, and my three year old declared it the best sauce ever and dipped EVERYTHING in it tonight. Broccoli. Bell pepper strips. Pasta noodles. She licked it clean. I’ve never seen this behavior in her before. Thanks for the magic tonight!
Richa
yay!!
Sherri
If I double the recipe I double all the ingredients? Like 14 cloves of garlic?!?
Richa
you can use less garlic, use a bit less liquid/water than double , for everything else double
Alison Hughes
So it really is meant to say SEVEN cloves of garlic?!! That seems really excessive!? What’s a realistic amount to use to still get the garlicky flavour without getting banned from public transport for the next week! LOL!
Richa
😀 2 or 3 is good enough. it gets cooked so it shouldnt be that strong a smell/flavor. If its raw then it lingers for a long while.
Erica
Can I use more potato for lack of cauliflower??
Richa
yes, but do use some nuts or seeds for creaminess as potatoes will make a thick starchy sauce
Heids
This is so so so good! it is now one of my fave recipes! thank you!
Richa
yay!
