The Wonderful World of Pesto: Beyond Basil

When most people hear the word “pesto,” they immediately envision the classic Italian blend of fresh basil, savory Pecorino cheese, crunchy pine nuts, pungent garlic, and rich olive oil. However, the concept of creating a flavorful paste from herbs, nuts, cheese (or cheese alternatives), and oil has a rich history that spans far beyond the Ligurian coast of Italy and dates back to ancient times. Many cultures around the world have their own versions of vibrant, herb-based sauces, proving that pesto is a truly universal delight.

As a passionate cook and health advocate, I’m certainly no stranger to making pesto. But I always enjoy finding new ways to put a healthy, creative spin on traditional recipes. Who wouldn’t love a dip, spread, or sauce that’s not only bursting with flavor but also loaded with beneficial nutrients? This approach allows for greater versatility, often reduces costs, and opens up a world of seasonal possibilities.

During the peak of summer, when my garden is overflowing with fragrant basil, I frequently prepare large batches of traditional Vegan Basil Pesto. But the beauty of pesto lies in its adaptability. There are countless other delicious ways to craft this versatile sauce, such as incorporating often-overlooked ingredients like carrot greens. Why let those nutrient-rich carrot tops go to waste when they can be transformed into something so incredibly yummy and unique?

This particular recipe for walnut arugula pesto holds a special place in my heart, and it might just be my favorite pesto creation yet! The ingredients are generally more affordable, exceptionally nutrient-dense, and readily available in most grocery stores year-round. The end result is an incredibly tasty and dynamic pesto that’s especially fantastic for making a vibrant pesto pasta salad, or simply spreading on toast.

Why This Walnut Arugula & Spinach Pesto is a Game Changer

I am genuinely thrilled with how this specific pesto recipe turned out. It offers a light, incredibly fresh taste that evokes the feeling of spring, yet it’s robust enough to be warmed as a sauce without losing its integrity. Its sturdy texture also makes it an awesome spread for toast, crackers, or sandwiches. It’s truly a multi-purpose culinary superhero and a fantastic way to incorporate healthy, vibrant greens into your diet. This pesto is not just a condiment; it’s a versatile base for countless healthy and delicious meals.

Beyond its fantastic flavor, this vegan pesto offers several advantages:

  • Speed & Simplicity: Whipping up a batch takes merely 5 minutes, making it perfect for busy weeknights or impromptu gatherings.
  • Dairy-Free & Vegan: It’s naturally dairy-free and vegan, making it suitable for a wide range of dietary needs without sacrificing any flavor.
  • Nutrient Powerhouse: Packed with the goodness of arugula, spinach, and walnuts, it’s a healthy boost to any meal.
  • Cost-Effective: Arugula and walnuts are typically more budget-friendly than basil and pine nuts, offering a gourmet taste without the gourmet price tag.
  • Bold Flavor Profile: The peppery kick of arugula combined with the richness of walnuts and the briny notes of capers creates a deeply satisfying umami flavor that stands out.

This pesto is proof that healthy eating can be both easy and extraordinarily flavorful!

Key Ingredients & Smart Substitutions

Crafting this flavorful walnut arugula pesto relies on a handful of simple, wholesome ingredients. Here’s a closer look at what you’ll need and why each component is essential, along with some helpful substitution tips:

Labeled ingredients: arugula, walnuts, hemp seeds, olive oil, capers, lemon, garlic, spinach, nutritional yeast, salt and pepper.
  • Arugula: This peppery green is the star of our pesto, offering a distinct, slightly bitter, and robust flavor that makes this recipe truly unique. Beyond its delicious taste, arugula is a nutritional powerhouse, low in calories yet rich in vitamins K and A, calcium, and antioxidants, making it an excellent nutrient-dense choice. Plus, it’s often much more affordable than fresh basil, especially when you need a larger quantity for pesto.
  • Spinach: To balance the bold flavor of arugula and add more green goodness, we incorporate fresh spinach. Spinach is mild in taste and contributes a lovely creaminess and vibrant green color to the pesto, while also boosting its iron and vitamin content. It helps create a smoother, richer texture without overpowering the other flavors.
  • Walnuts: These crunchy nuts are a fantastic, budget-friendly alternative to pine nuts. When lightly toasted, walnuts develop a deeper, richer flavor that adds incredible depth to the pesto. They’re also an excellent source of plant-based protein, healthy fats, and those all-important Omega-3 fatty acids, making this pesto incredibly nourishing.
  • Hemp Seeds: A true superfood, hemp seeds contribute a soft, creamy texture and a mild, nutty flavor. They are an amazing source of complete protein, fiber, and omega-3 and omega-6 fatty acids, enhancing both the nutritional profile and the mouthfeel of your pesto. If you don’t have hemp seeds, you can try a small amount of sunflower seeds or even more walnuts.
  • Capers: These tiny, briny flower buds are a secret weapon in vegan pesto recipes. They deliver a powerful punch of salty, tangy, umami flavor that beautifully mimics the savory depth traditionally provided by cheese. You won’t even miss the dairy when capers are in the mix! Be sure to drain them well before adding.
  • Nutritional Yeast:This flaky ingredient is a staple in dairy-free cooking, providing a distinct, cheesy flavor that enhances the umami in our pesto. It’s a simple, whole-food way to boost a dairy-free recipe without relying on heavily processed cheese alternatives. For an even more authentic “parmesan” experience, you can take an extra 5 minutes to make my recipe for dairy-free parmesan cheese and add it in here instead of the straight nutritional yeast.
  • Lemon (zested and juiced): Fresh lemon is crucial for brightening the flavors and adding a zesty tang that cuts through the richness of the nuts and oil. The zest provides aromatic oils, while the juice offers essential acidity. Don’t skip the zest – it makes a huge difference!
  • Garlic: A foundational ingredient in any pesto, garlic provides a pungent, aromatic base that ties all the flavors together. We recommend grating it finely to ensure it disperses evenly throughout the sauce.
  • Olive Oil: High-quality extra virgin olive oil is the backbone of any good pesto, providing richness, a silky texture, and healthy monounsaturated fats. Use a good-quality oil for the best flavor.
  • Sea Salt and White Pepper: Essential for seasoning and enhancing all the other ingredients. White pepper is often used in lighter-colored sauces to avoid visible black flecks, but black pepper works just as well if that’s what you have on hand.

Step-by-Step: Crafting Your Perfect Walnut Arugula Pesto

Making this incredible vegan walnut arugula pesto is remarkably simple and quick. In just a few easy steps, you’ll have a batch of fresh, vibrant pesto ready to enjoy!

1. Toast the Walnuts for Enhanced Flavor

Walnuts toasting in a stainless steel pan.

For an extra layer of nutty depth and aroma, I always recommend toasting the walnuts before blending. Simply place them in a dry pan over medium-high heat. Continuously shake the pan to ensure even toasting and prevent burning. In just 2-3 minutes, you’ll notice the natural oils releasing, the color darkening slightly, and a wonderfully fragrant aroma filling your kitchen. This small step makes a significant difference in the final taste of your pesto.

2. Combine All Ingredients in a Food Processor

Once your walnuts are perfectly toasted and cooled slightly, gather all your ingredients. Place the arugula, spinach, toasted walnuts, hemp seeds, nutritional yeast, drained capers, olive oil, sea salt, and white pepper into the bowl of your food processor. For ultimate convenience and to save on dishes, grate the garlic and zest your lemon directly over the processor bowl before squeezing in the lemon juice.

Process the mixture until all ingredients are well incorporated and have formed a coarse paste. Stop and scrape down the sides of the bowl as needed to ensure everything is blended evenly. Then, gradually add up to ¼ cup of cold water, 1 tablespoon at a time, continuing to process and scrape down the sides after each addition, until your pesto reaches your desired creamy, vibrant consistency.

3. Taste, Season, and Serve!

Finally, taste your freshly made pesto and adjust the seasoning as needed. You might want a little more salt, a dash of pepper, or an extra squeeze of lemon juice to perfectly balance the flavors. For those who appreciate a touch of heat, a sprinkle of crushed red pepper flakes adds a wonderful kick. Your homemade vegan walnut arugula pesto is now ready to be enjoyed!

Debra’s Expert Tips for Pesto Perfection

Achieving the perfect pesto is all about smart techniques and ingredient knowledge. Here are some of my top tips to make your walnut arugula pesto truly shine:

img 4624 11
  • Streamline with Grating & Zesting: To save precious time and minimize dishwashing, grate your garlic cloves and zest your lemon directly over the food processor bowl. Not only is it efficient, but it also ensures that all the aromatic oils from the lemon zest are captured right where they’re needed, maximizing flavor.
  • Optimize Your Nuts: Always buy your nuts raw for maximum versatility and freshness. Raw nuts can be easily toasted at home (as demonstrated in this recipe) to bring out their rich, complex flavors. For extended freshness, store your nuts in an airtight container in the freezer – they’ll stay good for months and prevent them from going rancid.
  • Achieve the Perfect Consistency: When adding water to your pesto, start with a smaller amount (e.g., 2 tablespoons) and gradually add more, 1 tablespoon at a time, until you reach your desired consistency. Different food processors and preferences will vary, so this allows for custom control.
  • Prevent Browning for Storage: To keep your pesto looking vibrant green when stored, pour a thin layer of olive oil over the top of the pesto in an airtight container before refrigerating. This creates a barrier that prevents oxidation.
  • Freezing for Future Use: Pesto freezes beautifully! Spoon it into ice cube trays and freeze until solid. Once frozen, transfer the pesto cubes to a freezer-safe bag or container. This allows you to easily thaw individual portions whenever you need a quick burst of fresh flavor. It can be stored in the freezer for up to 3 months.
  • Don’t Waste Anything: Embrace the “nose-to-tail” philosophy of cooking even with plants! If you have other leafy greens like kale stems (peeled and finely chopped), beet greens, or even herb stems (like parsley or cilantro), consider adding a small amount to your pesto for added nutrients and unique flavor twists.

Unleash the Versatility: Creative Ways to Use Your Pesto

This vegan walnut arugula pesto is incredibly versatile and can be used in a multitude of delicious ways beyond just pasta! Its vibrant flavor and creamy texture make it a fantastic addition to almost any meal. Here are some ideas to inspire you, including how to make a fantastic pesto pasta salad:

img 4624 12
  • Pesto Pasta Salad (as detailed below): A classic for a reason! The fresh pesto elevates simple pasta and vegetables into a satisfying meal.
  • Spread for Sandwiches and Wraps: Ditch the mayo! This pesto makes a healthier, more flavorful spread for your favorite sandwiches, wraps, or even as a base for a gourmet grilled cheese.
  • Pizza or Flatbread Sauce: Use it as a vibrant base instead of traditional tomato sauce for a unique and delicious pizza. Top with roasted vegetables and dairy-free cheese.
  • Dipping Sauce: Serve it with fresh crusty bread, vegetable sticks, or crackers for an easy appetizer or snack.
  • Roasted Vegetable Enhancer: Toss roasted vegetables like zucchini, bell peppers, asparagus, or potatoes with a dollop of pesto after they come out of the oven for an instant flavor boost.
  • Marinade for Plant-Based Proteins: Marinate tofu, tempeh, or your favorite plant-based chicken alternatives in this pesto before grilling or baking for a burst of flavor.
  • Soup or Stew Swirl: Swirl a spoonful into warm vegetable soups or stews just before serving for added depth and freshness.
  • Breakfast Boost: A little pesto on scrambled tofu or even avocado toast can be a delicious way to start your day.

Easy Pesto Pasta Salad

Creating a delightful and colorful pesto pasta salad is quick and easy with your homemade walnut arugula pesto:

  • Cook Pasta Al Dente: Prepare your favorite pasta according to package directions. If using gluten-free pasta, be extra vigilant and start testing for doneness around 6 minutes, as it can quickly turn gummy if overcooked.
  • Reserve Pasta Water: Before draining, set aside at least 1 cup of the starchy pasta cooking water. This liquid is gold for creating a creamy sauce.
  • Create Creamy Sauce: In the bottom of a large serving bowl, place 1 cup of your fresh walnut arugula pesto. Gradually whisk in ½ cup of the reserved pasta water until a smooth, creamy, and luscious sauce emerges. The hot pasta water helps emulsify the pesto and prevents it from being too thick.
  • Combine and Toss: Drain the cooked pasta thoroughly and immediately add it to the bowl with the pesto sauce. Toss everything together until the pasta is evenly coated and glistening.
  • Add Fresh Veggies & Protein: Enhance your pasta salad with an array of colorful raw or lightly blanched vegetables. Think shredded carrots, finely chopped red cabbage, diced bell peppers, cherry tomatoes, or tender zucchini ribbons. For an extra boost of plant-based protein, toss in some cooked edamame beans, chickpeas, or white beans.
  • Chill and Serve: Allow the pasta salad to chill in the refrigerator for at least 30 minutes to let the flavors meld. Serve chilled or at room temperature.
