Ingredients You’ll Need

The magic of this pesto lies in its simple but thoughtfully paired ingredients. Each element plays a key role in building its dynamic flavor profile, from the creamy texture of walnuts to the bright acidity of fresh lemon juice.

• Walnuts: Toasting these enhances their natural nuttiness and adds depth to the pesto’s texture.
• Garlic: Four cloves provide just the right sharp kick to complement the greens.
• Baby spinach: Offers a fresh, mild earthiness and beautiful vibrant color.
• Fresh basil leaves: The herbaceous star that adds aromatic brightness and that classic pesto note.
• Lemons (zest and juice): Essential for a lively citrus brightness that lifts the entire dish.
• Kosher salt and freshly cracked black pepper: Perfect for seasoning and balancing the flavors.
• Red pepper flakes or Aleppo pepper: For a subtle warming heat without overpowering the greens.
• Nutritional yeast: Adds a cheesy, umami richness that’s perfect for a dairy-free alternative.
• Extra virgin olive oil: The silky binder that creates the pesto’s luscious consistency.
• Capers (optional): Little bursts of tangy saltiness to give your pesto a delightful surprise.

How to Make Spinach Pesto with Lemon, Capers, and Nutty Basil Recipe

Step 1: Toast the Nuts to Unlock their Full Flavor

Start by heating a dry pan over medium-low heat. Add the walnuts and gently toast them, stirring often, until their aroma becomes irresistible and they turn slightly darker — this usually takes about 4 to 5 minutes. Toasting really awakens the nutty flavor, which forms the rich foundation of the pesto.

Step 2: Blend Nuts and Garlic into a Coarse Crumb

Transfer the toasted walnuts and garlic into your food processor. Pulse until the mixture resembles fine crumbs rather than a paste. This texture helps balance the pesto later by giving it a little body and bite, while ensuring the garlic’s pungency is evenly spread throughout.

Step 3: Add Greens and Blend to a Coarse Paste

Next, add the fresh spinach and loosely packed basil leaves in manageable portions, pressing them down carefully to fit if needed. Blend everything until you get a coarse, green paste. If your food processor is on the smaller side, you can do this in two batches to maintain the right texture and avoid over-pureeing.

Step 4: Brighten With Lemon and Season

Now it’s time to add lemon zest, freshly squeezed lemon juice, kosher salt, black pepper, chili flakes if using, and nutritional yeast. Blend again until the mixture becomes almost like a thick sauce. While the motor runs, slowly drizzle in the extra virgin olive oil to emulsify everything. Finally, if you love a little briny punch, toss in the capers and pulse a few times to incorporate them evenly.

Step 5: Taste and Adjust

Give your pesto a taste and tweak it with more salt or lemon juice if you feel it needs more brightness or seasoning. If your basil isn’t as vibrant as you hoped, a tiny pinch of sugar can help balance any bitterness. The end result is a thicker, creamier pesto than your typical basil sauce — rich, zesty, and utterly delicious.

How to Serve Spinach Pesto with Lemon, Capers, and Nutty Basil Recipe

Garnishes

Add your freshly made pesto as a finishing touch to grilled vegetables, roasted potatoes, or a warm bowl of pasta. Top dishes with extra toasted walnuts or a sprinkle of nutritional yeast for an added layer of texture and flavor. A wedge of lemon on the side allows guests to brighten their plate with a personalized squeeze.

Side Dishes

This vibrant pesto pairs wonderfully with crisp, fresh salads, crusty artisan bread, or even dolloped atop some creamy ricotta or labneh for a Mediterranean-inspired spread. It’s a fantastic complement to grilled chicken or fish, bringing bright notes that contrast rich proteins beautifully.

Creative Ways to Present

For a fun twist, try swirling the pesto into hummus or drizzling it over a homemade pizza just before serving. You can also transform it into a sandwich spread for an elevated lunchtime treat or fold it into warm grains like quinoa or farro to create a colorful, flavorful base for roasted veggies.

Make Ahead and Storage

Storing Leftovers

Keep your pesto fresh by storing it in a clean, airtight jar in the refrigerator. A thin layer of olive oil on top helps prevent oxidation and keeps the bright green color intact. It should stay delicious for up to one week when properly refrigerated.

Freezing

Freezing pesto is a fantastic way to preserve its flavor for months. Spoon it into ice cube trays for perfect portion sizes, freeze until solid, then transfer the cubes to a freezer-safe bag. This method makes it easy to thaw only what you need, maintaining that fresh, zesty quality for 3 to 4 months.

Reheating

When you’re ready to use frozen pesto, simply thaw it in the refrigerator overnight. Because pesto is typically served cold or at room temperature, reheating is usually unnecessary. If you want to warm it gently, do so over low heat while stirring, just until it loosens up, without overheating and losing its fresh flavor.

FAQs

Can I substitute walnuts with other nuts in this recipe?

Absolutely! Pine nuts are the traditional choice for pesto and work beautifully here, but toasted almonds or cashews can also make delicious alternatives. Just keep in mind that the flavor and texture will change slightly, so choose based on your taste preference.

Is nutritional yeast necessary, and can I omit it?

Nutritional yeast adds a lovely cheesy undertone, especially great for those avoiding dairy. You can omit it if you prefer or replace it with Parmesan cheese for a classic touch. Just remember to adjust the salt accordingly as cheeses tend to be saltier.

How spicy is this pesto with red pepper flakes?

The recipe calls for a mild amount of red pepper flakes or Aleppo pepper, offering just a gentle warmth that enhances rather than overpowers. If you prefer it milder, you can reduce or omit the chili altogether and still enjoy a flavorful pesto.

Can I make this pesto without a food processor?

While a food processor makes blending quick and easy, you can finely chop the garlic, spinach, basil, and toasted nuts by hand and then whisk everything together with olive oil and lemon juice. It will be a bit more labor-intensive but still delicious!

What dishes pair best with this Spinach Pesto with Lemon, Capers, and Nutty Basil Recipe?

This pesto is incredibly versatile. It tastes amazing stirred into pasta, spread on sandwiches, drizzled over roasted veggies, or used as a dip for fresh bread. It also pairs delightfully with grilled seafood or chicken for a bright, flavorful boost.
