Pin It My friend Sarah texted me a photo of her spiralizer with the caption 'now what?' and I realized she needed something beyond the usual raw zucchini salad. That evening, I made her this cashew Alfredo over zucchini noodles, and watching her face when she tasted that creamy sauce—the one that somehow tastes indulgent without a single drop of dairy—I understood why this became my go-to weeknight dinner. It's the kind of meal that feels like you're treating yourself, but you're actually eating something light and nourishing.
I made this for a dinner party where one guest was newly vegan, and I was nervous about whether it would feel like 'diet food.' But when she asked for seconds and then the recipe, I knew I'd nailed something real. That moment of watching someone's skepticism turn into genuine delight reminded me that the best meals are the ones made with a little extra intention.

Ingredients
- Zucchini, spiralized (4 medium): Fresh and tender, they cook down just enough to hold onto the sauce without turning mushy—the key is patting them dry before cooking.
- Raw cashews (1 cup soaked): Soaking is non-negotiable because it softens them for blending into that impossibly silky sauce.
- Unsweetened plant-based milk (1 cup): Almond or oat milk works beautifully; the unsweetened part keeps the sauce savory and lets the other flavors shine through.
- Nutritional yeast (2 tablespoons): This is your umami secret, adding a subtle cheesy depth that makes the whole thing feel authentic.
- Lemon juice (2 tablespoons): Brightness is everything here—it cuts through the richness and brings the whole sauce into focus.
- Garlic (2 cloves): Raw garlic blended directly into the sauce gives it punch without needing to cook it separately.
- Onion powder, sea salt, black pepper: These small amounts build layers of flavor that make the sauce taste complex and considered.

Instructions
- Get your zucchini ready:
- Spiralize your zucchini and pat the strands really dry with paper towels—this prevents them from releasing excess water that would water down your sauce. Trust me on this small step.
- Warm the noodles gently:
- Heat olive oil in a large skillet over medium heat and add your zucchini noodles, sautéing for just 2 to 3 minutes until they soften slightly. Season with sea salt, then set them aside—they'll continue cooking a bit from carryover heat.
- Blend the sauce until it's silky:
- Combine your soaked cashews, plant-based milk, nutritional yeast, lemon juice, garlic, onion powder, salt, and pepper in a high-speed blender. Blend until completely smooth, stopping to scrape down the sides a couple of times to ensure no cashew chunks hiding in the corners.
- Warm the sauce through:
- Pour your sauce into a saucepan and heat it gently over low heat for 3 to 4 minutes, stirring often so it warms evenly. If it looks too thick once heated, add a splash more plant milk to loosen it—the sauce should coat the noodles, not cling to them like glue.
- Bring it all together:
- Toss your warm zucchini noodles with the creamy sauce until every strand is coated. Serve right away while everything's still warm and the flavors are at their brightest.

There was an afternoon when my partner came home stressed from work, and I had this ready—nothing fancy, just good food that tasted like I'd spent hours on it. We ate quietly at the kitchen counter, and something about the simplicity of it, paired with how satisfying it actually was, shifted the whole mood of the evening. That's when I realized this recipe had become more than dinner; it was my quiet way of saying 'I've got you.'
Making the Sauce Your Own
The beauty of this cashew base is how adaptable it is once you understand the formula. I've stirred in a pinch of smoked paprika for depth, whisked in a teaspoon of white miso for umami complexity, and even added a touch of Italian seasoning when I wanted it to feel more herbaceous. Each time, it still tasted like the same comforting sauce, just with a new angle to it.
What to Serve It With
While the zucchini noodles are the traditional vessel, I've learned this sauce pairs beautifully with spiralized sweet potato for something slightly earthier, or even gluten-free pasta if you want something more substantial. A crisp white wine like Pinot Grigio alongside makes the meal feel restaurant-worthy, and a simple arugula salad tossed with lemon vinaigrette rounds out the plate without competing for attention.
Beyond the Basics
One evening, I added roasted cherry tomatoes and fresh basil to this, and it took on an entirely different personality—still creamy, still quick, but suddenly summery and bright. I've also tossed in sautéed mushrooms and spinach for nights when I want more substance, and the sauce accommodates these additions gracefully, wrapping around every ingredient like it was always meant to be there.
- Toast your pine nuts lightly before serving so they stay crispy and add real texture contrast to the creamy sauce.
- Keep extra plant milk on hand because blender-made sauces can thicken slightly as they cool, and you might need to loosen it.
- Leftovers reheat gently in a saucepan over low heat, thinning with more milk as needed to restore that silky consistency.

Recipe Questions & Answers
- → How do I prevent zucchini noodles from becoming watery?
Gently pat spiralized zucchini dry with paper towels before cooking. Sauté briefly for 2-3 minutes just until slightly tender—avoid overcooking to prevent excess moisture release.
- → Can I make the cashew sauce ahead of time?
Absolutely. Blend the sauce and store refrigerated in an airtight container for up to 4 days. Warm gently over low heat before tossing with noodles, adding splash of plant milk if thickened.
- → What can I substitute for cashews due to allergies?
Raw macadamia nuts or sunflower seeds work well as alternatives. For nut-free versions, try white beans blended with plant milk and nutritional yeast for creaminess.
- → Is nutritional yeast necessary for the sauce?
Nutritional yeast provides essential cheesy, umami flavor. Without it, consider adding white miso paste or a pinch of smoked paprika to maintain depth and savoriness.
- → Can I use regular pasta instead of zucchini noodles?
Yes, gluten-free pasta or whole grain pasta work beautifully. The creamy cashew Alfredo pairs perfectly with any pasta shape—adjust sauce quantity based on pasta amount.
