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.

Erica says
January 17, 2019 at 1:15 pmCan I use more potato for lack of cauliflower??
Richa says
January 17, 2019 at 1:21 pmyes, but do use some nuts or seeds for creaminess as potatoes will make a thick starchy sauce
Sherri says
March 20, 2019 at 4:34 pmIf I double the recipe I double all the ingredients? Like 14 cloves of garlic?!?
Richa says
March 20, 2019 at 5:31 pmyou can use less garlic, use a bit less liquid/water than double , for everything else double
Alison Hughes says
May 6, 2019 at 4:24 pmSo 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 says
May 6, 2019 at 5:12 pm😀 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.
Kristie says
April 2, 2019 at 9:10 pmOut 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!

June 8, 2019 at 4:25 pmHELLO 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!!!
Julie says
June 12, 2019 at 6:29 pmI 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!

Lauren says
August 5, 2019 at 8:09 amI 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 says
August 5, 2019 at 10:13 amyes omit them. taste when simmering and add more of the existing flavors if needed, like the soysauce, miso, garlic, herbs etc.

October 13, 2019 at 5:56 pmI’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 🙂

April 5, 2020 at 10:12 pmThis 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!

June 7, 2020 at 11:21 amHi Richa!
Can this be made without the potato?
Vegan Richa Support says
June 7, 2020 at 7:18 pmyes 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.
