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.

“Just made it for my family and it was waaaaay better than I could have imagined! So delicious and creamy (not to mention healthy!)” —Namita

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.

this was amazing!!!!
So happy you liked it, Erica! 🙂
It looks delicious
This was amazing especially since this is my first recipe using my spirilizer!!
So happy to hear, Shereen! Those spiralizers are life-altering, aren’t they?
How long does the avocado pesto keep for? I’m thinking of using this for my meal prep lunches this week but I’m a little hesitant as anything with avocado tends to get a bit funky after a few days….
Hi Christine! Avocado doesn’t generally stay great past 2 days so I wouldn’t use the sauce for meal prep. Perhaps you could mash up some avocado the day of and mix it with a spoonful of ready-made pesto!
Hi i live in South Africa where can i get one of those spiril thingy. …..
Hey, Erika! I had to buy mine online because even here than can be tricky to find in stores. They’re called “spiralizers” or “spiral slicers”. You may be able to purchase one here. 🙂
This was amazing. I just added an egg on top and it was beyond delicious! Thank you so much for this!
YUM! That’s a such a great idea, Mila! So happy you liked it and thanks so much for dropping a in a note 🙂
Will be trying out for sure. My only concern is the fat content- which I am assuming is mostly coming from the oil and avocado. I am thinking of adding some nuts (walnuts/pine nuts)
Hi Joanna, yes the fat content in this recipe is a bit high form the avocado and oil. You could try mixing in a bit of Greek yogurt to add a dose of protein. Pine nuts would also suit the recipe pretty well 🙂
This looks soooo good! I just purchased my Vegetti Spiralizer, and this sauce looks like the perfect addition.
How many people does this feed?
Hey Erika! It serves 2 to 3 people 🙂
I made this for work tomorrow this may sound stupid but do you heat up to eat or eat cold? I tasted it right after it was made and it is awesome !
Hi Kelly! It’s totally up to you 🙂 They’re good cold or reheated and warm!
Keep your avocados fresh and green by using lime juice (or lemon juice). The citrus keeps the oxidation down. I’ve kept guac for 5 to 6 days without it turning brown.
I use this trick all the time! Plus adds a nice dash of flavor 😀
