The Origins and Keto Benefits of Vegan Zucchini Noodles with Walnut Pesto

This dish is born from the desire to create a meal that is as nourishing as it is delicious. The idea of combining zucchini noodles with pesto isn’t new, but when you add the keto twist, it becomes an innovative way to enjoy a classic favorite without the carbs. The vegan keto zucchini noodles with walnut pesto recipe is a celebration of fresh, whole ingredients that come together to form a symphony of flavors.

Zucchini is a keto dieter’s best friend. It’s low in carbs and calories but high in essential nutrients like vitamin A, vitamin C, and potassium. When turned into noodles, zucchini provides the perfect base for a variety of sauces, especially pesto. Walnuts, the star of our pesto, are a powerhouse of omega-3 fatty acids, which are crucial for brain health and reducing inflammation. They also add a delightful texture and depth to the pesto, making it a robust complement to the light zucchini noodles.

The inclusion of nutritional yeast in the pesto brings a cheesy flavor without the dairy, making it ideal for vegans. It’s also a fantastic source of B-vitamins, which are important for energy production. Olive oil, another keto staple, provides healthy monounsaturated fats and helps to create a smooth, luxurious pesto that coats the noodles perfectly.

Every ingredient in this dish has been chosen for its nutritional profile and ability to support a ketogenic diet. The combination of low-carb zucchini with high-fat pesto ensures that you stay within your macros while enjoying a meal that’s as satisfying as it is healthy.

Preparing Vegan Keto Zucchini Noodles

Mastering the Method: Elevate Your Vegan Keto Cooking Skills

Creating the perfect vegan keto zucchini noodles with walnut pesto is about more than just following a recipe; it’s about mastering the art of cooking with keto-friendly ingredients. Let’s break down the process and infuse it with tips and tricks to elevate your dish.

To start, when making the pesto, it’s important to pulse the ingredients before blending to ensure that each element is given its moment to shine. The texture should be creamy but with enough body to remind you of the walnuts’ presence. As you drizzle in the olive oil, watch for the transformation from a chunky mix to a cohesive sauce, and stop when you’ve reached the desired consistency.

When preparing the zucchini noodles, patting them dry is crucial. This step is often overlooked but makes all the difference in avoiding a watery dish. The key is to sauté the noodles just long enough to warm them through, maintaining their al dente texture. Overcooking can lead to limp noodles, which we want to avoid.

Finally, tossing the noodles with the pesto off the heat allows the flavors to meld without compromising the freshness of the basil or the delicate nature of the zucchini. Serve immediately to enjoy the full spectrum of flavors at their peak.

Variations to Keep Your Keto Diet Exciting

Spicy Avocado Pesto Zoodles

For those who enjoy a kick, blend a ripe avocado and a dash of red pepper flakes into your pesto. The avocado adds creaminess and healthy fats, while the red pepper flakes provide a spicy twist that complements the zucchini noodles beautifully.

Hearty Mushroom and Spinach Zoodles

Sauté some sliced mushrooms and spinach before adding the zucchini noodles to the pan. The mushrooms will add a meaty texture, and the spinach will wilt into the dish, providing extra nutrients and a pop of color.

Roasted Tomato and Garlic Zoodles

Roast cherry tomatoes and whole garlic cloves in the oven until caramelized, then toss them with your zoodles. The sweetness of the tomatoes and the intensity of the roasted garlic will elevate the dish to new heights.

Substitutions for Every Keto Pantry

While the recipe is designed to be keto-friendly, there are always options to tailor it to your pantry or dietary needs. Here are some substitutions that maintain the low-carb integrity of the dish:

Almonds for Walnuts: If walnuts aren’t your thing or you’re looking for a different flavor profile, almonds can be a great substitute. They still provide healthy fats and a satisfying crunch.

Sunflower Seeds for Nutritional Yeast: If you’re allergic to yeast or prefer a nuttier flavor, sunflower seeds can be used in place of nutritional yeast. They’ll add a different dimension to the pesto while keeping it dairy-free.

Lemon Zest for Lemon Juice: If you’re out of fresh lemons, lemon zest can be a great alternative. It provides a concentrated lemon flavor without the additional liquid, which can be beneficial in controlling the consistency of your pesto.

Frequently Asked Questions

Q: Can I make the zucchini noodles ahead of time?

A: Yes, you can spiralize the zucchini ahead of time, but be sure to store them in an airtight container in the fridge and pat them dry before cooking to remove any excess moisture.

Q: Is there a nut-free alternative for the pesto?

A: For a nut-free version, try using seeds like pumpkin or hemp seeds as a substitute. They’ll give you a similar texture and are packed with keto-friendly fats.

Q: How can I prevent the pesto from turning brown?

A: Adding a touch more lemon juice can help prevent oxidation. If you’re storing it, place a layer of plastic wrap directly on the surface of the pesto before sealing the container.

Q: Can I freeze the leftover pesto?

A: Absolutely! Freezing pesto is a great way to preserve it. Use an ice cube tray for portioning, and once frozen, transfer the cubes to a freezer bag for long-term storage.

Q: How can I increase the protein content of this dish?

A: Consider adding a sprinkle of hemp seeds, or for those not strictly vegan, a dollop of Greek yogurt can add protein and create a creamy texture in the pesto.

  • Spiralizer
  • Food processor
  • Skillet
  • Measuring cups and spoons
  • Cutting board
  • Kitchen knife
  • Paper towels


Zucchini Noodles

  • 2 medium zucchini spiralized, approx. 1 lb or 450g
  • 1 tbsp olive oil

Walnut Pesto

  • 1 cup raw walnuts
  • 2 cups fresh basil leaves
  • 3 garlic cloves minced
  • ½ cup olive oil
  • ¼ cup nutritional yeast
  • 1 lemon juiced, about 2 tablespoons or 30 ml


  • Begin by preparing the walnut pesto. In a food processor, combine the raw walnuts, fresh basil leaves, minced garlic, nutritional yeast, and lemon juice. Pulse until the ingredients are roughly chopped.
  • With the food processor running, slowly drizzle in the olive oil until the mixture becomes smooth and emulsified. Season the pesto with salt and pepper to taste. Set aside.
  • Next, take the spiralized zucchini noodles and pat them dry with paper towels to remove excess moisture. This step ensures that your noodles won't become soggy when cooked.
  • Heat a large skillet over medium heat and add 1 tablespoon of olive oil. Once the oil is shimmering, add the zucchini noodles and sauté for 2-3 minutes, just until they're tender. Season with salt and pepper.
  • Remove the skillet from the heat. Toss the zucchini noodles with the walnut pesto until they are evenly coated. Serve immediately, garnishing with additional nutritional yeast or fresh basil if desired.


If you don't have a spiralizer, a vegetable peeler can be used to create thin strips of zucchini that resemble noodles.
To store leftover pesto, place it in an airtight container and refrigerate for up to a week. It can also be frozen for future use.
Adjust the thickness of the pesto by adding more olive oil for a thinner consistency or more walnuts for a thicker texture.
