Summer Spaghetti with Zucchini-Cashew "Alfredo" Sauce (gluten free, vegan, dairy free, soy free)
I like pureeing raw zucchini, cooking the puree, and using it as a milk substitute in baked goods. Then not long ago, it dawned on me that this creamy zucchini "milk" could be used in place of milk in other things - like creamy soups, smoothies, or sauces. The idea for an alfredo-style cream sauce was born. I've been kicking around that concept for awhile, and finally had the chance to give it a shot last weekend when I was home visiting my family. The secret ingredient is soaked cashews, which add a rich flavor and velvety texture to our perennial garden favorite. Soaked and blended cashew cream does something magical when you cook it: it thickens, just like dairy does. Perfect for making thick sauces.
Creamy and rich, my zucchini-cashew "alfredo" sauce was the perfect finish to al dente brown rice spaghetti and an abundance of fresh farmer's market summer vegetables and garden herbs. The sauce had a great thick texture, creamy white color, and an awesome flavor, and was a breeze to make. It totally passed the test with my parents, who both went in for second helpings. My mom enjoyed it as is, but my dad, a true Wisconsite, added a bit of parmesan cheese to his bowl. What can I say, the man loves his cheese.
SUMMER SPAGHETTI WITH ZUCCHINI-CASHEW "ALFREDO" CREAM SAUCE (gluten free, vegan, dairy free, soy free)
8 oz Tinkyada brown rice spaghetti (or other tolerated pasta)
Prepare alfredo sauce according to directions below.
Prepare vegetables. Thinly slice onion. Remove rib from chard, and slice on diagonal into 1/2" slices. Cut the leaves in half lengthwise, stack, roll, then thinly slice across the roll to julienne. Quarter the fennel bulb, then slice. Slice the carrots into 1/4" diagonal slices. Slice the zucchini into 1/4" half moons. Thinly slice basil leaves.
Cook spaghetti according to directions on packaging, then rinse well with cool water.While spaghetti is cooking, heat olive oil in a large saute pan over medium heat. Add onions, and saute a few minutes, then add chard ribs and carrots, and saute a few more minutes. Then add zucchini, and saute a few more minutes. When vegetables are nearly done, add chard leaves and a little water, cover, and steam until tender.
Add cooked pasta to saucepan with vegetables. Then add warm alfredo sauce and basil leaves, and stir to mix over low heat. Transfer to serving bowl(s) and garnish as desired. Enjoy!
- Switch out your greens: use spinach, kale, or other greens in place of Swiss chard
- Try using other combinations of vegetables: green, red, purple, or yellow peppers, eggplant, mushrooms, peas, broccoli, cauliflower, celery, squash, pumpkin, shallots...
- Garnish with chopped olives, capers
- Season with other herbs, like dill, chives, or rosemary
ZUCCHINI-CASHEW "ALFREDO" CREAM SAUCE (gluten free, vegan, dairy free, soy free)
1 large zucchini, peeled and coarsely chopped (about 3 cups chopped)
Soak the cashews in fresh water for 2 hours. Drain and rinse, and place in blender.
Peel and chop the zucchini, and add to blender with garlic and 1 c of water. Puree until totally smooth and creamy. Transfer to saucepan and bring to a simmer over medium heat. Reduce heat to low and cook for about 10 minutes, stirring frequently, until cooked through and thickened.
Right before serving, take out about 1/2 c of the sauce and stir in miso paste until evenly mixed. Add miso sauce back to saucepan and stir until well combined. Season to taste with salt and pepper, and keep warm on lowest heat until ready to serve.
- Serve over pasta, grains, vegetables, or beans, use in casseroles or pot pies in place of "cream of whatever" soup, or use as a fondue style dip
- use broth or stock instead of water for richer flavor
- Béchamel-style sauce: omit garlic and add a pinch of nutmeg (start with 1/4 tsp)
- Rich and creamy red sauce: puree in roasted red peppers or marinated sun-dried tomatoes
- Wine sauce: try using a bit of white wine instead of water when blending
- Creamy green goddess sauce: puree in greens and herbs
- Mushroom sauce: add sauteed mushrooms to sauce, pureeing half of them and adding the other half to the saucepan
- Onion sauce: add caramelized onions to blender and puree
- Herb sauce: add a variety of fresh herbs
- Vegetable sauce: for a chunky vegetable cream sauce, add finely chopped cooked vegetables to saucepan and cook with sauce - broccoli would be delicious!
- Here's a total change of pace: what about omitting the garlic, adding vanilla, cocoa/carob, and a little sweetener of choice? It would be like a thick chocolate sauce. You could even use hot coffee or a grain-coffee substitute instead of water for a mocha effect. I NEED TO TRY THIS!

What an ingenious idea! I have to try this-yum!
Ricki, it seems up your alley! I'm sure you'll come up with some sort of grand improvements - let me know how you like it and what you do. I still haven't had the chance to try out the carob date pancakes - soon, soon!
First – I just found your blog and wanted to tell you it is so wonderful! There are many things I don’t eat and it is great to know there is someone else in the world whose diet is a little off the beaten path.
This recipe looks awesome! I might try the “alfredo” in a cauliflower & yellow squash gratin.
Metta
Hi Metta,
That sounds great - I think the sauce would be perfect for a gratin. Let me know how it turns out! I was thinking it would also be awesome in lasagna. Or even as a white sauce on some sort of GF pizza : ) I'm so glad you like the blog, I checked yours out and I like your creative and experimental cooking projects - and the names: "Hemp Carrot Thing" made me giggle - and it looks good! Thanks for stopping by, I hope you can find things here you like!
Best-Kim
Today must be the day to find you - I'm new to your blog as well, and this alfredo looks delightful =D. I love the flavour combination! Yum!
I made the sauce this weekend and it is really good. I omitted the garlic b/c it has been making me nauseous :(. I added fresh basil, chives, and parsley. It tasted like something was missing (the garlic!), so I added a couple of olives and 1 tsp red South River miso for more tang. I’ve been enjoying it on kale and roasted cauliflower.

Hi Metta! I'm so glad you liked it - thanks for letting me know what you did to make it your very own! THe herbs sound great. So happy it worked out for you!
Had to comment here and say I made this creamy nut sauce last night and it was very good. I was apprehensive because my mom (a vegan) makes several things (gravies, sauces, etc) from cashews, but those have always upset my stomach. I gave this one a chance because the cashews were not the only ingredient in the sauce, and I'm so glad I did. It turned out very well, nice and creamy and rich. I used lots of fresh ground pepper, which was really good.
I had a whole different selection of veggies on hand, so my final product was not much like yours, but the sauce really pulled it together. Even my dairy-eating boyfriend was very impressed and couldn't stop talking about how good the dish was.
Thank you!
Leah, I'm so glad you and your dairy-eating bf loved it! I'm hankering for this sauce again, I just bought a bunch of zucchini, I think I have to make it some night this week :) THanks for the comment, as always! I'm so glad it sat well - I like that it isn't as rich as plain cashew sauce, which I agree, can be a bit intense.
Thank you so much for this recipe! I made it tonight with a few alternations to fit what ingredients we had and various other allergies. One of these adaptations involved only having half a zucchini, so I used the stalks from broccoli (which I added to the dish) too. And I made buckwheat noodles. So delicious!
I meant I used the stalks in the sauce. :)
Oh My Gosh is all I can say! This recipe is amazing! I have been off dairy do to food sensitives for about 4 months. And lately I've been craving the creamy, dairy-rich sauces that I can no longer eat. This hit the spot! I didn't feel like I was being deprived at all. I'll even admit I was licking the sauce out of the bottom of my bowl:) My dairy loving husband even liked it.
Kim, your blog has been a life saver for me! I'm now able to have many of the things I had to give up. Thanks for contributing to my taste buds and health with all of your wonderful recipes!!! Many blessing to you!
