Purple Basil Pesto Ingredients
For the Base
• Walnuts – a nutty flavor base that provides healthy fats and a delightful crunch.
• Purple Basil Leaves – adds a unique color and aromatic twist, enhancing the taste of the pesto.
• Minced Garlic – infuses a robust, savory punch that complements the other ingredients.
• Nutritional Yeast – gives a cheesy taste without dairy, making this a great option for vegan diets.
• Salt – enhances the flavors of all ingredients, ensuring the pesto is well-seasoned.
• Olive Oil – provides a smooth, rich texture and helps emulsify the sauce, making it easy to blend.

Step‑by‑Step Instructions for Purple Basil Pesto
Step 1: Process the Walnuts
Begin by placing the walnuts in a food processor. Pulse them for about 30 seconds or until they reach a fine, crumbly texture. This step creates a nutty base for your Purple Basil Pesto. Be sure to watch closely for a consistent grind, as uneven pieces can affect the overall creaminess of the pesto.
Step 2: Add the Remaining Ingredients
Next, add the vibrant purple basil leaves, minced garlic, nutritional yeast, and salt to the food processor. Then, pour in the olive oil, allowing it to coat the other ingredients. Close the lid tightly and prepare to blend, ensuring all beautiful flavors blend seamlessly into the pesto.
Step 3: Blend Until Smooth
Process the mixture for about 45-60 seconds, observing as it transforms into a luscious, green sauce. Pause to scrape down the sides of the processor occasionally, ensuring all ingredients are well incorporated. You’ll know it’s ready when the texture is mostly smooth, with a few bits of walnut for crunch.
Step 4: Adjust Consistency
If you prefer a creamier Purple Basil Pesto, drizzle in an additional tablespoon of olive oil. Pulse the processor again for another 15-30 seconds until you achieve your desired consistency. Taste and adjust flavors if necessary, appreciating the fresh and vibrant essence of your homemade pesto.
