If you love a silky, dairy-free sauce that clings to vegetable noodles, this Creamy Zucchini Noodles with Cashew Sauce is exactly the kind of weeknight dinner that feels both indulgent and light. Ready in about 25–35 minutes (plus cashew soak time), it’s great for low‑carb dinners, warm-weather meals, or any night you want something bright, lemony, and satisfying.

“A surprisingly luxurious weeknight pasta—light, bright, and unbelievably creamy without cheese.” — Home cook review
Reasons to make it now:
- Fast prep and cook time; great for busy evenings.
- Adaptable: swap nuts for coconut milk to avoid tree nuts.
- Great for meal-prep when served with a protein on the side.
- Kid‑friendly texture if you finely spiralize the zucchini.
Step-by-step overview
You’ll start by soaking or quick‑boiling cashews (or grabbing canned coconut milk), then blend them with lemon, nutritional yeast, and aromatics for a silky sauce. While the sauce comes together, spiralize and drain the zucchini (or prepare shirataki). A quick warm in the skillet with garlic finishes everything so the noodles are tender but not soggy. Total hands-on time is short, and most of the work is in prep and draining.
What you’ll need
- 2 medium zucchini (or 1 package shirataki noodles) — spiralized into ribbons
- 3/4 cup raw cashews, soaked 2–4 hours (or 1 cup canned full‑fat coconut milk if avoiding nuts)
- 1/2 cup unsweetened full‑fat coconut milk (if using soaked cashews, reduce to 1/4 cup)
- 2 tablespoons olive oil or avocado oil
- 3 garlic cloves, minced
- 2 tablespoons fresh lemon juice
- Zest of 1 lemon
- 1/4 cup nutritional yeast (optional, for cheesy depth)
- 1 teaspoon Dijon mustard (optional, for balance)
- 1/2 teaspoon sea salt, plus extra to taste
- 1/4 teaspoon freshly ground black pepper
- 1/4 cup chopped fresh basil or parsley
- 2 tablespoons chopped chives or green onions
Optional garnish: toasted pine nuts or pumpkin seeds, red pepper flakes
Ingredient notes and swaps:
- Coconut milk swap: Use 1 cup canned full‑fat coconut milk in place of cashews for a nut‑free version, and omit the extra 1/2 cup listed when using cashews.
- Shirataki noodles are a great zero‑carb alternative—rinse and dry them well to remove odor.
- Nutritional yeast adds umami; replace with 2 tablespoons grated hard cheese if not vegan.
Step-by-step instructions
- Prepare cashews (if using): Place cashews in a bowl, cover with water and soak 2–4 hours, then drain. For a quick option, boil cashews for 10 minutes and drain.
- Make the sauce: In a blender combine soaked cashews, 1/2 cup coconut milk (or 1 cup if not using cashews), lemon juice, lemon zest, nutritional yeast, Dijon, and 1/4 teaspoon salt. Blend until very smooth. If the sauce is too thick, add a splash of hot water and blend again until you reach a silky, pourable consistency. Taste and adjust salt, lemon, or yeast.
- Prepare the zucchini or shirataki: Spiralize zucchini and place in a colander with a pinch of salt for 5–10 minutes to draw out moisture. Pat dry with paper towels. If using shirataki, rinse well, boil 2–3 minutes, drain, then dry in a skillet over medium for 2 minutes to remove excess water and odor.
- Sauté aromatics: Heat oil in a large skillet over medium heat. Add minced garlic and cook 30–45 seconds until fragrant—don’t let it brown. Add the blended sauce and warm gently for 1–2 minutes; it should steam, not boil, to prevent separation.
- Toss the “pasta”: Add zucchini ribbons or prepared shirataki to the skillet. Toss gently to coat evenly. Cook 1–2 minutes more—just enough to warm through and soften slightly.
- Finish and season: Remove skillet from heat, fold in chopped herbs, and season with the remaining salt and black pepper. Adjust lemon or salt to taste.
- Plate and garnish: Divide into bowls, scatter toasted pine nuts or pumpkin seeds, and add a pinch of red pepper flakes if you like heat.
How to plate and pair
Serve the noodles warm, garnished with fresh basil and a grind of black pepper. For a protein boost and a complete meal, pair with grilled or roasted chicken; this recipe works beautifully alongside lighter mains like grilled chicken broccoli bowls with creamy garlic sauce. For sides, consider a crisp green salad, lemony roasted tomatoes, or crusty bread if you’re not keeping it low‑carb.
Storage and reheating tips
- Refrigeration: Store leftovers in an airtight container for up to 3 days. The sauce will thicken and zucchini may release water—stir in a splash of hot water or warm coconut milk when reheating.
- Freezing: Avoid freezing zucchini noodles; they become watery and mushy. You can freeze the cashew sauce (without zucchini) for up to 3 months—thaw overnight in the fridge and re-blend.
- Reheating: Gently warm in a skillet over low heat to prevent separation. Do not boil the sauce. For microwave reheating, use short intervals and stir between bursts.
Helpful cooking tips
- Dry the zucchini thoroughly: Salt draws out water; blot well with towels to prevent a watery final dish.
- Use a high-speed blender for an ultra-smooth sauce; if you only have a standard blender, blend longer and consider straining for extra silkiness.
- Don’t overcook: Zucchini should be tender-crisp. Overcooking makes it mushy and watery.
- Quick soak trick: If you forget to soak cashews, boiling them 10 minutes softens them enough for blending.
- Texture control: If your sauce is too thin, add a few extra cashews or a spoonful of nutritional yeast. If too thick, thin with hot water or a splash of coconut milk.
Creative twists
- Pesto-cashew: Add 1/4 cup basil pesto to the sauce for a herby lift.
- Spicy sun-dried tomato: Blend in 1–2 chopped sun-dried tomatoes and a pinch of smoked paprika.
- Lemon-garlic shrimp: Top bowls with quickly sautéed shrimp for a pescatarian option.
- Cream-of-mushroom variation: Sauté mushrooms with garlic and fold into the finished dish for an earthy take.
- Dairy swap: If not vegan, replace nutritional yeast with 2 tablespoons grated Parmesan for a cheesier profile.
Common questions
Q: How long do cashews need to soak?
A: For best texture, soak raw cashews 2–4 hours in room-temperature water. If short on time, boil them 10 minutes and drain—this softens them enough for a creamy blend.
Q: Can I make this completely nut-free?
A: Yes—omit cashews and use 1 cup canned full‑fat coconut milk as the creamy base. The texture will be slightly different but still rich.
Q: Will zucchini noodles get soggy if I make them ahead?
A: Yes, zucchini releases water over time. If prepping ahead, store the sauce and zucchini separately and toss just before serving. Spiralized zucchini is best within a few hours of prep.
Q: Is nutritional yeast necessary?
A: No—nutritional yeast adds savory, cheesy notes, but you can skip it or substitute a small amount of grated hard cheese if not vegan.
Q: Can I freeze leftovers?
A: Freeze the sauce (without zucchini) for up to 3 months. Cooked zucchini noodles don’t freeze well—they become watery when thawed.
