    Vegan Pasta with Roasted Cauliflower Cashew Sauce

    A delicious, soothing, comforting recipe of creamy pasta with a roasted cauliflower and cashew sauce. Basil adds summery flavor and edamame and mushrooms add nutrition and texture.
    Roasted Cauliflower Cashew Sauce with pasta and veggies in a bowl.

    Last week, Desi and I were helping care for a neighbor's dog, Elvis, for a couple of days while his parents went to a family wedding.

    Elvis is a huge yellow lab who, at two, is barely out of puppyhood. He is a terror on the leash and his idea of a walk is dragging whoever happens to be on the other end of the leash all through the neighborhood streets while he pants like a heated engine.

    But he's also a huge darling. The way Elvis greets people is by hurling all 100-plus pounds of himself at you. There was this time when he threw me down on the steps, planted his front feet firmly on my lap, and began to plant drooly kisses all over my face. Try as I did I could not get up and it was only after five long minutes that he decided I had gotten the message: he was happy to see me.

    Opie gets the same sort of treatment, but is a little less genial about it: when Elvis jumps at him, the smaller-- and much older-- Opie gets more than a little annoyed.

    But dogs are strange, if nothing else, and despite his reluctance to meet the rambunctious Elvis on walks, Opie loves nothing more than to greet him from across the fence.

    Often, when we walk, he will point us in the direction of Elvis's home, hoping he'll be out in his fenced yard. He'll run up the small hill to the fence, look for Elvis, and make little whiny sounds if he isn't there. If Elvis does happen to be outside, he will sniff at whatever part of Elvis he can reach through the fence while the other dog hurls himself with unbridled excitement at the pickets. Then, as if in quiet disdain for all this enthusiasm, Opie will plant himself on the grass and ignore Elvis completely.

    Did I say dogs are strange?

    Desi, who is great at making friends human and canine, has gathered a menagerie of friends for Opie. Besides Elvis, there's Tilda, an elegant golden retriever who has the most gorgeous tail and who can run like the wind. She will never stop long enough to let Opie get a good sniff, which is maddening to him.

    There are Toby and Mitzi, two of the cutest bichons you ever saw. After a quick greeting, Toby and Opie immediately move on to trying to mount each other in a show of dominance. Mitzi, the dignified girl, stands apart, unwilling to become part of this display of testosterone.

    And there's Otis, a sage-looking Shepherd mix who looks a lot like my Lucy. Otis and Opie have a silent understanding: they meet, they greet, and then each goes and does his own thing even as their parents catch up with each other. It's like they're saying, it's nice to see you, but I have nothing more to say. And that's okay.

    Roasted Cauliflower Cashew Sauce with pasta and veggies in a bowl.

    I have a creamy pasta recipe for you today that's going to make you want to lick the bowl until every last trace is gone. Much like Opie when he gets his favorite dinner. My Pasta with a Roasted Cauliflower and Cashew Sauce.

    I came up with this recipe trying to use up half a head of cauliflower I had in the refrigerator. I have shared another cauliflower-based pasta sauce with you on this blog before, and like I said then, I hate the boiled cauliflower smell. For that recipe, a Pasta Gratin, I baked the pasta with the sauce and it was perfect. But this time I had another idea which was even better: I roasted the cauliflower first. Then I pureed it in a blender with a paste of roasted cashews and some chipotle pepper until it was quite divine.

    To cuddle with this dreamy sauce I used some whole wheat shell or conchiglie pasta.

    This is a deceptively simple recipe-- it tastes and sounds like it would take a long time to make, but it really only needs minutes. And to make it even healthier, do as I did and throw in it handfuls of veggies. I used asparagus, mushrooms and edamame. Lima beans or chickpeas would also be great here.

    On to the recipe. Enjoy, all!

    • ยฝ cup of cashews lightly roasted in the microwave
    • 1 chipotle chilli pepper with 1 teaspoon of the adobo sauce
    • 6 basil leaves
    • 1 cup almond milk

    Instructions

    • Roast the cauliflower, Spray a baking sheet with oil, pace the cauliflower florets in a single layer, and spray the tops with oil. Roast in a 350-degree oven for 30 minutes or until the cauliflower is quite tender and browning.
    • Roast the asparagus. Toss first with some salt and pepper, spray a baking sheet, and spread the asparagus in a single layer on the sheet. Roast in a preheated 350-degree oven for 12-15 minutes until the asparagus is tender but has a good bite. Set aside.
    • Cook pasta per package directions until al dente.
    • While the pasta is cooking, heat the oil and add the mushrooms with some salt and pepper.
    • Saute, stirring frequently, until the mushrooms start to caramelize and soften.
    • Add the edamame. Stir well and cook for a couple of minutes or until the edamame are warmed through.
    • Make the cauliflower-cashew sauce by placing the roasted cauliflower in a blender along with the toasted cashews, chipotle chili and adobo sauce, basil leaves, almond milk and lemon juice in a blender. Blend until very smooth. Add salt to taste.
    • In a large bowl, mix the mushroom-edamame mixture, the pasta, the asparagus and the cauliflower sauce.
    • Garnish with some parsley, if desired, and serve immediately.

      What a lovely recipe! I just had lunch at a place called the Sanctum restaurant here in Orlando, FL and I had their "Caulifredo!" I asked for the recipe, but apparently it's top secret? ? So I took to the internet and low & behold this sounds very close! It was a cauliflower-cashew sauce. So thank you so much for sharing this! I have a question. I don't use my microwave for anything anymore, so how should I prepare the cashews? I'm a rookie cook. So I need cooking for dummie recipes. After turning to a plant-based lifestyle, I've learned that my days of eating out are extremely limited, so I had to learn to cook. Reluctantly. Lol
      I will be following your page from now on! Someone just told me about the Holy Cow app! So great name!

        Hi Kim, roast the cashews lightly in a skillet, that'll be just as good. And I don't have an app-- unless you mean this website. Hope you enjoy the recipes!

          Oops! It was HappyCow! ? It's an app to find vegan restaurants.

          Now for roasting the cashews. Do I use any oil? Or just throw them in the pan? What temperature should I put the pan on? Medium? Sorry, I really am very new to cooking, so I need every little detail. Thank you so much!

      I once made an "alfredo" sauce with cashew cream (without cauliflower) but it tasted a little too sweet...does this sauce have some sweetness to it? Or does the cauliflower make it more savory?

        Hi Marie, I would say it tastes rather neutral, because of the cauliflower.

      I started using purรฉed cauliflower years ago when making any white sauce. It added a cheesy texture and lightened the dish, as well as increased the number of servings. My kids LOVE this even thought they have no idea what my secret ingredient is and how much healthier it is for them. In fact, many of their friends think my white sauce is the best. Now, I have a new white sauce to add to my list. Thank you!!!

        Lisa, that's a brilliant idea to add pureed cauliflower to a white sauce. And have it pass the kid test. ๐Ÿ™‚

      This sauce sounds delicious -- creamy and rich and spicy and deep all at once. Not to mention that I have both a head of cauliflower and one of romanesco at home right now! I bet either one would make an amazing sauce. ๐Ÿ™‚

      I love your recipes ... I'm rather financially depleted presently because of renos on my newly acquired summer home. So pasta is on my menu until spring. I feed a hungry 24 year old "hard at it " law student son. Who fortunately has a great appitite and never snubs my cooking. I like variety and I too love to ear and cook. Sooo keep creating and sharing. I thank you wouldn't our world be a better place if we all learned to share as you so generously do. Thanks from mother and son. Penelope and keavin et al.
