Vibrant Vegan Arugula Pesto: A Peppery Twist on a Classic

I remember my first summer working in a small trattoria in Tuscany. Basil pesto was practically a religion there, but one day, the chef, a wonderfully eccentric woman named Nonna Emilia, ran out of basil. Scrambling, she grabbed a handful of arugula from the garden, its peppery bite a stark contrast to the sweet basil we were used to. The resulting pesto was a revelation – vibrant, complex, and utterly addictive. I’ve been playing with arugula pesto ever since, and this vegan version is a testament to Nonna Emilia’s resourceful spirit and the delicious possibilities that open up when you embrace unexpected ingredients.

• Total Time: 10 minutes
• Servings: Varies
• Yield: 1 small batch
• Dietary Type: Vegan, Gluten-Free, Dairy-Free

Ingredients

• ¼ cup pine nuts
• 3 garlic cloves, minced
• 2 cups coarsely chopped arugula, stems included
• ¼ cup coarsely chopped fresh basil
• 2 tablespoons nutritional yeast flakes
• Sea salt, to taste
• Fresh ground black pepper, to taste

Equipment Needed

Instructions

1. Begin by adding the pine nuts, minced garlic, coarsely chopped arugula, fresh basil, and nutritional yeast flakes to the bowl of a food processor.
2. Pulse the ingredients several times until they are coarsely chopped and begin to combine.
3. With the food processor running, slowly pour in the extra virgin olive oil in a thin, steady stream. Continue processing until the mixture forms a smooth, slightly thick paste. You may need to stop and scrape down the sides of the bowl occasionally to ensure even blending.
4. Once the pesto reaches your desired consistency, season it generously with sea salt and freshly ground black pepper.
5. Add a pinch of ground cayenne pepper for a subtle kick.
6. Taste the pesto and adjust the seasonings as needed. Add more salt for enhanced flavor, pepper for added spice, or cayenne for extra heat.
7. Use immediately in sandwiches, pasta, rice, salad dressings, or any dish that could benefit from a burst of fresh, peppery flavor.

Expert Tips & Tricks

• Toast the pine nuts: For a richer, nuttier flavor, lightly toast the pine nuts in a dry skillet over medium heat until golden brown and fragrant, about 3-5 minutes. Watch them carefully, as they burn easily. Let them cool completely before adding them to the food processor.
• Control the bitterness: Arugula can sometimes have a bitter edge. Balancing it with fresh basil and a good amount of olive oil helps to mellow the bitterness.
• Adjust the consistency: If your pesto is too thick, add a tablespoon or two of extra virgin olive oil to thin it out. If it’s too thin, add a few more pine nuts or a tablespoon of nutritional yeast.
• Don’t over-process: Over-processing the pesto can make it bitter. Aim for a smooth but slightly textured consistency.
• Infuse the oil: For a more complex flavor, infuse the extra virgin olive oil with garlic before making the pesto. Gently heat a few crushed garlic cloves in the olive oil over low heat until fragrant, then remove the garlic and let the oil cool before using.
• Spice it up: For extra heat, add a small, seeded and minced jalapeño pepper to the food processor along with the other ingredients.
• Herb Variations: Feel free to experiment with other herbs! Arugula pairs well with mint, parsley, or even a little bit of spinach for a milder flavor.

Serving & Storage Suggestions

This vibrant vegan arugula pesto is incredibly versatile. Toss it with your favorite pasta for a quick and flavorful meal. Spread it on sandwiches or wraps as a delicious alternative to mayonnaise. Use it as a marinade for grilled vegetables or tofu. Drizzle it over salads or roasted potatoes for a burst of fresh flavor.

To store, transfer the pesto to an airtight container and press a thin layer of olive oil over the top to prevent oxidation. Store in the refrigerator for up to 5 days. You can also freeze pesto for longer storage. Divide it into ice cube trays or small freezer-safe containers and freeze for up to 3 months. Thaw in the refrigerator before using.

Variations & Substitutions

• Nut-Free Pesto: Replace the pine nuts with sunflower seeds or pumpkin seeds for a nut-free version. Toast them for added flavor.
• Oil-Free Pesto: For a lower-fat option, reduce the amount of olive oil and substitute with water or vegetable broth. Add a tablespoon or two at a time until you reach the desired consistency. The flavor will be less rich, but still delicious.
• Lemon-Arugula Pesto: Add the zest and juice of one lemon to the food processor for a bright, citrusy twist.
• Spicy Arugula Pesto: Add a pinch of red pepper flakes or a finely chopped chili pepper to the food processor for an extra kick.
• Sun-Dried Tomato Arugula Pesto: Add ½ cup of oil-packed sun-dried tomatoes (drained) to the food processor along with the other ingredients.

A: Yes, pre-washed arugula is perfectly fine to use. Just make sure to dry it thoroughly before adding it to the food processor.
