Ingredients
Servings
2
- 2 medium zucchinis, spiralized into noodles
- 1 cup raw walnuts
- 1/4 cup fresh basil leaves
- 2 tablespoons nutritional yeast
- 2 cloves garlic, minced
- 1 tablespoon fresh lemon juice
- 1 teaspoon ground turmeric
- 1/2 teaspoon ground cumin
- 1/4 teaspoon ground black pepper
- 1/4 teaspoon cayenne pepper (optional, for heat)
- 1/4 teaspoon sea salt
- 3 tablespoons extra virgin olive oil
- 2 tablespoons water (as needed to blend pesto)
- Fresh parsley, chopped (for garnish)
Instructions
-
Spiralize the zucchinis into noodles using a spiralizer or julienne peeler. Place in a large bowl and lightly sprinkle with a pinch of salt to draw out excess moisture while you prepare the pesto.
-
In a food processor, combine the raw walnuts, fresh basil, nutritional yeast, minced garlic, lemon juice, ground turmeric, ground cumin, black pepper, cayenne pepper (if using), and sea salt.
-
Pulse the mixture to roughly blend ingredients, then slowly stream in the olive oil while processing to form a smooth pesto.
-
If needed, add water 1 tablespoon at a time to achieve a creamy, spreadable texture.
-
Drain any excess liquid from zucchini noodles and gently toss them with the spiced walnut pesto until well coated.
-
Divide the coated noodles between two plates and garnish with chopped fresh parsley.
-
Serve immediately as a refreshing cold dish, or let it rest 5–10 minutes to enhance flavors. Enjoy as a nutritious lunch, light dinner, or post-workout meal.
Frequently Asked Questions
Reader questions and answers for this recipe will appear here.
This vegan, low-calorie, paleo-friendly recipe featuring spiced walnut pesto and spiralized zucchini noodles is naturally wholesome and nutrient-rich. To customize according to your dietary needs or preferences, here are some alternative ingredient suggestions:
- Walnuts: Swap with pecans or cashews for a different nutty flavor and similar creamy texture. For nut allergies, pumpkin seeds (pepitas) or sunflower seeds make sturdy, anti-inflammatory substitutes.
- Nutritional Yeast: Offers umami, cheesy notes. If unavailable, try miso paste or finely ground toasted sunflower seeds for depth without dairy.
- Spices (Turmeric, Cumin, Cayenne): These deliver the anti-inflammatory and energy-boosting benefits. Omit cayenne for a milder flavor, or substitute cumin with coriander for a fresh aromatic twist.
- Zucchini Noodles: Experiment with spiralized cucumber or carrot noodles for added crunch and variety, maintaining a low-calorie, fiber-rich base.
- Olive Oil: Extra virgin olive oil supplies healthy fats key for paleo diets. Avocado oil or walnut oil are also excellent paleo-friendly, anti-inflammatory fat options.
For enhanced protein and muscle-building benefits, consider pairing the dish with legumes such as lentils or chickpeas, or sprinkling with hemp seeds or ground flaxseed to boost protein and omega-3 content while keeping it vegan and balanced.
