Creamy Avocado Sweet Potato Noodles

We are in love with this easy veggie noodles recipe. We toss perfectly cooked sweet potato noodles with our homemade avocado lime sauce. The sauce is almost too good and it’s delicious with sweet potato. It’s a spin off from the creamy cilantro sauce we use on these easy roasted veggie tacos.

Guilt-Free 25-Minute Sweet Potato Pasta

This is such a quick and easy recipe. It’s adaptable, too. It is excellent using 100% sweet potato noodles, but a combination of sweet potato and regular potato is a fun spinoff. You could even swap the sweet potato for butternut squash, zucchini or regular spaghetti.

Sweet potato noodles recipe with a creamy dairy-free avocado sauce

If you have never made noodles out of vegetables, then you are in for a treat. They are really quite simple to make and are becoming so popular that some stores are selling them already cut into noodles!

It’s easy to do at home, though. You don’t even need a spiralizer (although, it does make quick work of them). Here’s a quick breakdown of doing it yourself.

  • The easiest way to make sweet potato noodles is to use a spiralizer. They make long, curly noodles in minutes. This is a great tool to add to your kitchen and are pretty inexpensive. Ours cost around $25 and is the Paderno model, but there are lots of excellent options out there.
  • You can also use a julienne vegetable peeler. These come in at under $10 and might even be hiding in your kitchen gadget drawer right now. The noodles won’t be curly, but they will be spaghetti-like.
  • Most mandoline slicers will make noodles. All you need is the attachment that makes lots of thin strips instead of one wide strip.
  • You can also use a standard vegetable peeler and make wide noodles.

Once you’ve got noodles, you’re ready to cook them.

Cooking Sweet Potato Noodles

Sweet potato is perfect for making noodles — they hold up much better than zucchini (which has lots of water). Here are our tips for cooking them:

  • Use a non-stick pan. This tip comes from Ali over at Inspiralized. Since sweet potatoes have some sugar in them, they can become caramelized and stuck to the bottom of the pan. Using a non-stick skillet and oil helps to prevent this.
  • Don’t overcook. The noodles should be cooked to al dente (just like pasta). This means they will look wilted, but still have a slight crunch.

Creamy Avocado Lime Sweet Potato Noodles

  • PREP
  • COOK

This healthier take on pasta with avocado sauce is simple, fresh and quick to make. The sauce is perfect for tossing with vegetable noodles or regular pasta (it’s also excellent as a dip for veggies or spread for sandwiches). The recipe below makes about 2 cups of sauce. You will only need about 6 tablespoons. Don’t worry though, you can store it and keep in the fridge for days. It’s even freezer-friendly! Check the notes section below for our tips on storing it.

Makes two generous servings

You Will Need

Creamy Avocado Sauce

1/2 cup pepitas (pumpkin seeds)

1 medium avocado, pit removed and flesh scooped out

1/2 cup packed cilantro leaves and tender stems

1 jalapeño, seeds and white membrane removed

1 teaspoon minced garlic (1 clove)

1/4 cup fresh lime juice, from 1 to 2 limes

3 tablespoons extra-virgin olive oil

1 cup water

1/4 teaspoon sea salt or more to taste

Sweet Potato Noodles

1 tablespoon avocado oil or olive oil

2 medium sweet potatoes, peeled and spiralized (1 pound of noodles)

1/2 teaspoon sea salt

Half of a lime

6 tablespoons creamy avocado sauce or more as needed

Cilantro leaves, toasted pepitas and queso fresco for serving


  • Make Sauce
  • 1Add pepitas to a skillet over medium heat. Toast, stirring often, until the seeds begin to pop, 3 to 5 minutes. Take off of the heat and set aside 2 tablespoons of the seeds for serving. Use the rest to make the sauce.

    2Add pepitas (minus the reserved tablespoons for serving), avocado flesh, cilantro, jalapeño, garlic, lime juice, olive oil, water and the salt to a food processor or blender. Blend until smooth. If the sauce seems too thick, blend in a few more tablespoons of water. Taste then adjust with more salt as needed (we use about 1/2 teaspoon).

    3Store sauce in the refrigerator with a sheet of plastic wrap pressed on top to prevent air from turning the avocado brown.

  • Cook Sweet Potato Noodles
  • 1Heat the oil in a wide non-stick skillet over medium heat. Add sweet potato noodles to the pan and season with the salt. Toss with pasta tongs and cook until al dente — the noodles should be wilted, but still have a slight crunch; 5 to 7 minutes. Do not let the noodles cook any longer or else they will become mushy and fall apart. As they cook, keep tossing so that all the sweet potato noodles have a chance to hit the bottom of the skillet.

    2Squeeze half of a lime over the noodles then toss with 6 tablespoons of the creamy avocado sauce.  If the noodles seem dry, add an extra tablespoon. Serve with a few cilantro leaves, the reserved peptitas and if you like, some queso fresco on top.

Adam and Joanne's Tips

  • How to make sweet potato noodles without a spiralizer: The spiralizer is not the only way to make noodles. You can use a julienne vegetable peeler or a mandoline. You can also use a standard vegetable peeler to make wide noodles or ribbons.
  • Make it vegan or paleo: This is a vegan-friendly recipe and is paleo-friendly, simply leave out the queso fresco (and depending on your diet, the salt).
  • Substitute pepitas: Pepitas are shelled pumpkin seeds and are quite inexpensive to buy. Pistachios, pine nuts, almonds, and walnuts are also excellent options for making the sauce.
  • Add protein: These noodles are more filling than you’d think, but adding some protein on top is a nice idea. We especially love grilled or baked chicken, tofu and shrimp.
  • Storing the leftover sauce: Since it has avocado blended in, when the sauce is left uncovered for an extended period of time it might turn brown. To prevent this, press a sheet of plastic wrap directly onto the sauce and store in the refrigerator. The sauce should last up to a week in the fridge when properly stored.
  • Other ways to use the sauce: Use any leftover sauce as a dip for vegetables, a sandwich spread or thin it out a little and use as a salad dressing.
  • Nutrition Facts: The nutrition facts provided below are estimates. We have used the USDA Supertracker recipe calculator to calculate approximate values. We omitted salt from the calculations since you will need to add to your tastes.

    This dish was sooo tasty! I followed it completely (except I cut the sauce in half). Everyone loved it. Such good flavors. It was very easy to make. I served it as a side with veggie patties. I am sure I will be making these noodles and sauce many times in the future. Thank you for this recipe!

    This dish was amazing!! First time making the sweet potato noodles and I loved them. This pesto is going to be my new go-to. I much preferred it to traditional pesto that relies mostly on cilantro and parsley. I did have to sub pine nuts because I couldn’t get pepitas, bit I toasted them and they still had that satisfying crunch. I also added some pan fried tofu but overall kept the ingredients as-is. Loved and shared!!

    Looks delicious, will try

  • Rachel December 4, 2019, 7:54 pm

    Super yummy! The sauce is a great combination with the sweet potatoes!

  • Rita August 13, 2018, 11:36 pm

    This was an absolutely amazing dish. So flavorful. I separately cooked some bite sized chicken thigh pieces (skinless, boneless). Then I put one layer of the sweet potato noodles on the plate, a number of chicken pieces, and the sauce all over the top. The sauce was delicious – great pairing with sweet potato noodles. This was a huge hit in my house. My new favorite!!

    Your recipes look great!

  • Meghan January 11, 2018, 5:21 am

    Wow! I made cut this recipe in half and had this as a side to our Jamaican jerk pork tenderloin! It seriously is one of the best things I’ve had in quite a while and I am a spirilizing fool from LA! Soo wonderful! This will be a part of our rotation! My husband is on a 30 day clean eating detox challenge and this is a perfect dish for that!

  • Lindsay January 4, 2018, 7:54 pm

    I just made these noodles for dinner and they were great! The sauce was delicious and easy to make. I will definitely be making this again!

    After having some spiralizing issues, I made your Creamy Avocado Sweet Potato Noodles. It turned out amazing, so flavorful, nothing I would have come up with. And very easy. Things I love about your site are that you offer alternatives and other options to create a good outcome. There is always that one darn ingredient I don’t have on hand, and it helps so much. I also like the way you combine things that are out of the ordinary and are SO good.
    Keep up the good work!

    This recipe sounds incredible. I am so fascinated by the spiralized recipes I’ve been seeing around the web lately! The flavors in this (avocado OMG) sound awesome. -jessie from cakespy
