Equipment You’ll Need For Creamy Vegan Lemon Zucchini Pasta
Nothing too fancy, just a few essentials:
- Blender – for whipping the cashews, lemon, and beans into a creamy sauce
- Spiralizer – for turning zucchini into zoodles
- Large pot – for cooking the spaghetti
- Large skillet or pan – for sautéing the zoodles and combining everything
That’s the full list. No food processor needed beyond the blender, no specialty gadgets sitting unused in your cabinet. Ever notice how the best fast meals require the least fuss? This one’s no exception.
Why This Sauce Actually Tastes Creamy Without Any Dairy
Here’s the trick behind this whole recipe: soaked cashews blended with white beans create a genuinely creamy, protein-rich sauce without a drop of cream or butter. The cashews bring richness, the beans add body and extra protein, and the lemon cuts through it all with brightness.
I used to assume vegan “cream” sauces were always a slight compromise compared to the real thing. Turns out that’s just not true when the technique is right. Blending hot water with the cashews helps them soften and emulsify faster, which means you skip the usual hours-long soaking step most cashew cream recipes demand.
And because zucchini noodles join real spaghetti in this dish, it delivers on every promise of fresh plant-based summer comfort food hearty, bright, and genuinely quick enough for a busy weeknight.
The Ingredients Breakdown

Here’s exactly what you need:
- 3 tbsp cashews
- 200 ml water, hot, plus more for cooking the pasta
- 250 g spaghetti
- 2 tbsp salt, for cooking the pasta
- ½ tsp salt, for the sauce
- 4 cloves garlic
- 2 zucchinis, not too thick or large (so they fit well in the spiralizer)
- 1 organic lemon you need the zest and juice (approximately 4 tbsp)
- Black pepper
- 30 basil leaves, approximately, with a few set aside to garnish
- 2 tbsp nutritional yeast
- 200 g cooked white beans
- 3 tbsp olive oil, plus a little more for garnishing
- Dried chili, optional
- Homemade vegan almond feta, optional
Grab an organic lemon specifically, since you’re using the zest here, and conventional lemon peels often carry pesticide residue you don’t want in your sauce. This is one of those small details that actually matters.
Zoodles and Spaghetti- Why Both?
You might be wondering why this recipe uses both zucchini noodles and regular spaghetti instead of picking one. Fair question. The combination gives you the bulk and bite of real pasta alongside the lightness and freshness of zoodles, so you’re not stuck choosing between a heavier carb-forward dish or an overly light vegetable-only one.
It also happens to be a genius way to sneak more vegetables into a pasta dinner without anyone feeling like they’re “eating healthy” in a sad way. Ever tried convincing a picky eater that zoodles are just as good as noodles? Mixing them together solves that argument entirely.

Step-by-Step Instructions
Time to actually make this.
Step 1- Soak the cashews. Put the cashews in the blender jug and cover them with the hot water. Let them start softening while you prep everything else.
Step 2- Cook the spaghetti. Bring a pot of water with the 2 tbsp salt to a boil and cook the spaghetti according to the package instructions until al dente.
Step 3- Prep the zoodles and garlic. While the pasta cooks, finely chop the garlic and pass the zucchini through a spiralizer on the thin setting. Cut the resulting zoodles in half twice with a knife, since long zoodles are genuinely impractical to eat otherwise.
Step 4- Blend the sauce. Grate the lemon zest and add it to the cashews, reserving a little for garnish. Squeeze in the lemon juice, then add the ½ tsp salt, black pepper, basil leaves (again, saving a few for garnish), nutritional yeast, and 4 tbsp of the cooked white beans. Blend until smooth and creamy.
Step 5- Sauté the aromatics. Heat the olive oil in a pan and sauté the chili (if using) and chopped garlic for about 30 seconds over medium heat.

Step 6- Cook the zoodles briefly. Turn the heat up to high and add the zoodles. Cook for only about 30 seconds any longer and they’ll turn mushy, which nobody wants.
Step 7- Combine everything. Turn off the heat and add the cooked, drained spaghetti, the remaining white beans, and the blended lemon-cashew-basil mixture. Stir everything together and let it stand for 1-2 minutes so the flavors meld.
Step 8- Garnish and serve. Plate the pasta, garnish with a little extra lemon zest and finely chopped basil, and drizzle with a bit more olive oil. Grate some vegan Parmesan on top if you like, or better yet, crumble on some homemade vegan almond feta.
Tips for Getting This Right Every Time
A few things I’ve learned from making this more times than I can count:
- Don’t over-cook the zoodles. That 30-second window is real cook them any longer and they release too much water and turn soggy.
- Use hot water for the cashews. It speeds up the softening process significantly compared to cold or room-temperature water.
- Taste before adding all the salt. Nutritional yeast and beans both bring their own subtle saltiness, so adjust at the end rather than over-salting upfront.
- Zest before you juice. It’s much easier to zest a whole lemon than a juiced, floppy one.
Storage & Reheating
This pasta is genuinely best eaten fresh, since the zoodles release moisture over time and the sauce can separate slightly once refrigerated. If you do have leftovers, store them in an airtight container in the fridge for up to 2 days.
Reheat gently on the stovetop over low heat, adding a splash of water to loosen the sauce back up. Skip reheating in the microwave if you can it tends to make the zoodles go a little watery.
Frequently Asked Questions
Can I skip the spiralizer and just use extra spaghetti? Yes, though you’ll lose the lighter texture and extra vegetable boost the zoodles provide. If you don’t own a spiralizer, thinly julienned zucchini with a knife works as a decent substitute.
Is this recipe gluten-free? Not as written, since it uses regular spaghetti. Swap in your favorite gluten-free pasta and the rest of the recipe stays exactly the same.
Can I use a different nut instead of cashews? Cashews are ideal here because they blend into a smooth, neutral cream, but soaked blanched almonds can work in a pinch with a slightly different texture.
Why does my sauce taste too tangy? Lemons vary in acidity, so start with a bit less juice than called for, taste, and add more gradually until it’s balanced to your liking.

My Final Thoughts

This Creamy Vegan Lemon Zucchini Pasta (Under 15 Minutes) proves that a genuinely creamy, satisfying sauce doesn’t need a single dairy product to pull it off. Soaked cashews, white beans, and a whole lot of fresh lemon do all the heavy lifting here.

Blend up this sauce, toss in your zoodles and spaghetti, and let bright, creamy comfort food come together in under 20 minutes.
