With over 50 five-star reviews, this zucchini pasta with avocado pesto is a well-tested and delicious low-carb alternative to spaghetti. Feel free to use store-bought zucchini noodles for an even quicker and simpler recipe.

Many families turn to pasta on busy nights. While we love wheat noodles as much as the next person, zucchini is soft enough to cut into the perfect spirals, and its neutral flavor makes it great as a pasta substitute!
This zucchini pasta is topped with a creamy avocado sauce with basil and lemon. It’s a true celebration of garden flavors. After making this so many times, I can confirm it works equally well with store-bought zoodles as it does with homemade ones.

Here’s what you’ll need
- For The Pesto: You’ll need an avocado, garlic, fresh basil, olive oil, salt, pepper, and lemon juice. Readers have had great success using dried basil and whole lemon slices cooked in the sauce and then removed. You might also need water to thin out the sauce.
- Zucchini: Any large zucchini variety works well. These get sauteed in a bit of olive until bright green.
to make zoodles
The easiest way to make zucchini noodles is with a spiralizer. If you don’t have a vegetable spiralizer, simply cut the zucchini into ¼-inch wide strips or peel into thin “fettuccini” using a vegetable peeler.

let’s make zucchini pasta
- Make the pesto in a food processor, adding water 1 tbsp at a time until it comes to a fluid yet thick consistency.
- Prepare the zucchini noodles by sauteing them in a splash of olive oil. Drain any excess water.
- Combine the noodles and sauce and then top with a bit of parmesan cheese for serving.

why not boil zucchini noodles?
While you would usually boil pasta, don’t go that route here! Boiling zucchini leaches out water-soluble vitamins (vitamin C and B6 in the case of zucchini). Instead, saute the zucchini noodles on the stove with a touch of olive oil until they are soft.

alternative sauce options
I love this creamy avocado sauce, but here are a few other options.
- Romesco is simple to make at home so if you have extra, toss it with zoodles.
- Marinara can be made with fresh tomatoes or bought in-store for a quick dinner.
- Traditional pesto uses a similar technique to this avocado pesto but with parmesan for creaminess.

I bought the spiralizer. That thing is great. It makes perfect noodles with no effort. I was afraid you made it look easy and I would have a pile of goo. Thanks dor the suggestion
Yay! So happy you’re enjoying it! 😀
Yummy recipe! Will definitely make again 🙂
So happy to hear it, Michelle! 😀
Hi Sarah,
I love your website. I am a born vegetarIan and never had meat, fish, chicken, or eggs in my life. I always look for news ides to make healthy meals.
Thank you for great ideas.
Best,
Atul
So happy to hear you’re liking the recipe ideas, Atul! 😀
Excellent recipe! Creamy texture, balance of flavors. Coated the zucchini really nicely! We added sauteed onions, garlic cloves and mushrooms in too! Sarah is right to say LARGE portions. We had plenty of sauce left over, as the zucchini was a generous side dish. But it definitely will not go to waste. So delicious!
One person said their zucchini was mushy. Personally, earlier in the day, I spiralize and then (like eggplant) salt the zuchinni on lots of paper towels to remove the excess liquid. By evening, when I cook, there isn’t really any liquid at all left in the pan. Still plump and fresh.
So happy to hear it, Janice! Thanks for dropping in to let us know how it went! 😀
Fantastic and simple! I added some cherry tomatoes for a splash of red. Went beautifully with the meal.
YUM! I love to roast or saute the tomatoes for a bit before throwing them in. So much yum!
this looks absolutely delicious. thanks for sharing
I accidentally bought frozen zucchini noodles instead of fresh – am I doomed? Is this salvageable? Thanks!
I haven’t tried them before, but I think if you follow the instructions on the package they should be okay!
The taste is so delicious , perfect consistency! I am breastfeeding and baby and I are dairy free at the moment . This recipe satisfied my creamy “cheese “ craving.
Easy and really good. I added some plain tofu baked in the airfryer for extra protein sprinkled some nooch on top and it was really good. I’ll definitely make it again.
Hi! I am following the keto diet. I see 16g of carbs. Are they net carbs? I am still new and a bit confused 🙂
Net carbs would be total carbs minus fiber, so 16 – 9 = 7 in this case! 😀
