Why You’ll Love This Recipe

This recipe uses a unique blanching technique to keep your homemade vegan pesto a truly vibrant, beautiful green. This is unlike other recipes that often turn brown quickly due to oxidation. Briefly blanching some of the basil leaves stops the browning process, and the ice water helps maintain that bright green color while assisting in a better emulsion for the pesto.

Toasting the pine nuts or walnuts brings out an even richer, deeper nutty flavor, enhancing the overall taste profile significantly.

This vegan pesto is quick and easy to make in under 15 minutes. It is naturally vegan and dairy-free, making it perfect for those with various dietary restrictions. Most importantly, it is incredibly flavorful and wonderfully versatile for countless dishes.

Ingredients Needed

2 cups packed fresh basil ((large stems removed))
3 Tbsp pine nuts or walnuts ((if nut-free, try sunflower seeds!))
3 large cloves garlic ((peeled))
2 Tbsp lemon juice
3-4 Tbsp nutritional yeast
1/4 tsp sea salt ((plus more to taste))
2-3 Tbsp extra virgin olive oil*
3-6 Tbsp water ((plus more as needed))

Ingredient Notes & Substitutions

For basil, it is essential to wash your fresh basil leaves thoroughly and dry them completely before use. Excess water will dilute your pesto’s flavor. When measuring, pack the basil tightly into your measuring cup to ensure you have the correct volume. Two cups of packed fresh basil is approximately 60-70 grams.

Regarding nuts, you can easily make this a nut-free pesto by substituting pine nuts or walnuts with sunflower seeds or hemp seeds. Other delicious nut options include cashews or pistachios for a slightly different flavor profile.

Nutritional yeast is a key ingredient for achieving that cheesy, umami flavor in vegan pesto. It is inactive yeast that comes in flake or powder form. Be sure to use an unflavored variety, as some brands offer fortified or flavored versions that might alter the taste.

For the oil, if you prefer an oil-free pesto, you can substitute the extra virgin olive oil with vegetable broth or just use additional water. Be aware that this will impact both the richness of the flavor and the final texture of your pesto.

If you like, you can also add some vegan Parmesan cheese to this recipe. If you choose to do so, remember to adjust the amount of sea salt accordingly, as vegan Parmesan can be quite salty.

How to Make Vegan Basil Pesto

Prepare the Ingredients

To a food processor or small blender, add the basil, pine nuts or walnuts, peeled garlic cloves, fresh lemon juice, nutritional yeast, and sea salt. As these ingredients come together, you will start to smell the wonderful, pungent aroma of the garlic and fresh basil. Using a small food processor or blender is crucial for small batches, ensuring all ingredients are finely processed into a smooth, even texture.

Blend to Consistency

Blend or mix the ingredients on high until a loose paste forms. Then, begin to add the extra virgin olive oil a little at a time. If your machine allows, stream the oil in slowly while the processor is running. This slow addition helps the oil emulsify beautifully with the other ingredients, creating a stable and creamy sauce. Scrape down the sides of the bowl as needed to ensure everything is incorporated. Next, add 1 tablespoon of water at a time until your desired consistency is reached. You are looking for a thick but pourable sauce. If you are avoiding oil altogether, simply substitute the oil with vegetable broth or use more water instead.

Adjust Flavor to Perfection

Once the desired consistency is achieved, taste the vegan basil pesto and adjust the flavor as needed. Add more nutritional yeast for extra cheesy flavor, more sea salt for overall flavor enhancement, more nuts for nuttiness, additional garlic for a stronger bite or zing, or extra lemon juice for increased acidity. This step is critical to personalize the pesto to your liking. A tiny pinch of sugar or maple syrup can also help balance any strong acidity if desired.

Serving Suggestions

This vibrant vegan pesto is perfect for adding to sauces, dressings, breads, and so much more! My favorite recently has been tossing it straight with zucchini or carrot noodles for a beautiful, healthy side dish. You can also mix it into pasta or pasta salads, spread it on bread or avocado toast, or use it as a flavorful base for pizza, adding it after baking for the best fresh flavor.

Storage Guidelines

Store any leftover vegan basil pesto covered in the refrigerator for up to 1 week. To extend its freshness, pour the pesto into ice cube molds and freeze. Once frozen, transfer the pesto cubes to a freezer bag and store them for up to 1 month or more. To reheat frozen pesto, simply add the cubes directly to hot cooked pasta; the heat will thaw it quickly. You can also thaw it in the refrigerator overnight or microwave gently in short intervals.

Blanching Basil for Vibrant Color

Have you ever wondered why your homemade pesto sometimes turns brown? It is primarily due to oxidation, a natural enzymatic reaction that occurs when the basil leaves are broken down and exposed to air. This process causes the chlorophyll, which gives basil its vibrant green color, to degrade.

The secret to keeping your Vegan Basil Pesto a stunning, bright green is a simple blanching technique for some of the basil. Here is how I do it:

First, bring a small pot of water to a rolling boil. While the water heats, prepare an ice bath by filling a bowl with ice and cold water.

Next, take about half of your fresh basil, roughly 1 cup. Carefully submerge this portion of basil into the boiling water for just 15 to 20 seconds. This brief heat shock is enough to set the chlorophyll and stop the browning enzymes without cooking the basil.

Immediately after blanching, use a slotted spoon to transfer the basil directly into the ice bath. This rapid cooling halts the cooking process and locks in that beautiful green color.

Finally, once the basil is completely cooled, remove it from the ice bath and thoroughly dry it. You can gently squeeze out excess water or use a clean kitchen towel. It is crucial for the basil to be very dry before adding it to your food processor to prevent a watery pesto.

Incorporating this blanched basil along with some fresh basil into your pesto mixture, and adding a tablespoon or two of ice water during blending, creates a truly vibrant and smooth green pesto that resists browning.

Pro Tips & Troubleshooting

Pro Tips

Always lightly toast your pine nuts or walnuts before blending them. This simple step deepens their nutty flavor through the Maillard reaction, significantly enhancing the pesto’s taste.

When adding the extra virgin olive oil, stream it in slowly while the food processor is running. This method is key for the best emulsification, resulting in a smooth, creamy texture.

Adjust the water carefully. Some basil varieties are juicier than others and may require less water to achieve the desired consistency. Start with a smaller amount and add more as needed.

For an optional touch, add a tiny pinch of sugar or maple syrup. This can help to balance the acidity from the lemon juice, especially if your basil is particularly peppery.

Consider adding a tiny splash of mellow white miso paste for an extra layer of umami flavor. This contributes a subtle depth without overpowering the basil.

Always use high-quality extra virgin olive oil. The oil is a prominent flavor component, and a good quality oil will make a noticeable difference in your pesto.

If your pesto turns out too thick, add more water or oil, one teaspoon at a time, until it reaches your preferred consistency.

If your pesto is too thin, you can thicken it by adding a few more nuts or a bit more nutritional yeast, then blend again.

Common Mistakes to Avoid

A common mistake is adding too much water initially. This can result in a too-liquid vegan pesto that loses its rich texture. Always add water incrementally.

Not packing basil enough for the specified volume can lead to an imbalance of flavors. Ensure you firmly pack the basil leaves when measuring.

Using a regular-sized food processor for small batches of pesto often results in chunky, unevenly processed ingredients. For optimal smoothness, use a small blender or a mini food processor.

Skipping the blanching step for some of the basil is a frequent error that leads to brownish pesto due to oxidation. Embrace the blanching trick for vibrant color.

Over-processing the pesto can heat it up, which can cause the basil to darken and degrade its fresh flavor. Blend just until smooth.

Failing to taste and adjust the seasoning as you go is a missed opportunity. Pesto needs careful balancing of salt, acidity, and richness to suit your personal preference.

Using old or stale nuts will result in a flat, sometimes rancid, flavor. Always use fresh nuts for the best taste.

Avoid using flavored nutritional yeast. Some brands offer varieties with added flavors that can clash with the delicate basil and other ingredients. Stick to plain, unfortified nutritional yeast.

Serving & Storage

Serving Ideas

My favorite way to enjoy this vegan basil pesto is as a simple yet flavorful sauce for zucchini or carrot noodles. It clings beautifully and makes for a light, healthy meal.

It is fantastic mixed into warm pasta or cold pasta salads, instantly elevating any dish.

Spread it generously on crusty bread, breadsticks, or avocado toast for a quick and delicious snack or appetizer.

Use it as a vibrant base for homemade pizza. For the best fresh flavor, drizzle it over your pizza after baking.

It makes a wonderful topping for hearty dishes like butter beans and cavolo nero kale.

Drizzle it over baked flounder with tomatoes and onions for a Mediterranean-inspired meal.

If you are not strictly vegan, it is also surprisingly delicious stirred into or dolloped on scrambled eggs.

And of course, serve it simply with some crusty bread for dipping and savoring every bite.

Storage and Make-Ahead

Store any leftover vegan basil pesto in an airtight container in the refrigerator for up to 1 week. To prevent the surface from browning due to air exposure, I like to pour a thin layer of extra virgin olive oil over the top before sealing and refrigerating.

For longer storage, freezing pesto is an excellent option. Simply spoon the pesto into ice cube trays. Once completely frozen, pop the cubes out and transfer them to a freezer-safe bag or container. It will keep well in the freezer for up to 1 month or even longer. This makes it incredibly convenient to pull out just the amount you need for future meals.
