About Kale Walnut Pesto

• Taste – Bright, herb-forward and slightly nutty; the kale gives a deeper green flavor than basil pesto.
• Texture – Smooth and creamy with a subtle crunch from the walnuts.
• Effort – Minimal: add the ingredients to a food processor and pulse.
• Time – Ready in about five minutes.

How to Enjoy Pesto

This gluten-free walnut pesto works as a condiment, a sauce, or a spread. It’s excellent tossed into pasta with a little reserved pasta water, spread on crostini with fresh cheese, swirled into warm gnocchi, or spread inside a grilled cheese for a garlicky lift. Use it on chicken, in pasta salads, or stirred into roasted vegetables for immediate flavor.

Ingredients

• Fresh torn kale – Leaves only, no stems; provides the pesto’s earthy backbone.
• Parmigiano-Reggiano – Adds savory depth and a creamy, umami finish.
• Walnuts – Raw or lightly toasted for nuttiness and body.
• Garlic cloves – For pungent, aromatic flavor.
• Extra virgin olive oil – Binds and enriches the sauce.
• Kosher salt – Enhances and balances the flavors.
• Freshly ground black pepper – A touch of heat and complexity.

Substitutions

• Nuts – Swap walnuts for toasted pine nuts, toasted pecans, almonds, or hemp seeds if preferred.
• Basil – If you prefer a peppery green note, try a similar recipe using fresh basil leaves.
• Nut-free – Omit nuts for a nut-free version; add extra cheese or seeds for body.
• Pecorino Romano – Replace a quarter of the Parmigiano-Reggiano with Pecorino for a sharper, saltier profile.

Variations

• Lemon – A tablespoon of lemon juice brightens the pesto and adds lift.
• Spicy – A pinch of crushed red pepper flakes adds heat.
• Vegan – Omit the cheese or use a grated plant-based alternative to make it vegan.
• Mixed greens – Add a couple of cups of spinach or other tender greens to stretch the kale and add vitamins.

Instructions

• Blend the kale and cheese – Place torn kale and grated Parmigiano-Reggiano in the food processor and pulse until the leaves are finely chopped, about 20–30 seconds.
• Add walnuts and garlic – Add walnuts and garlic and pulse until coarsely chopped and combined, about 30–60 seconds.
• Finish with oil and seasoning – With the processor running, stream in the olive oil until the mixture becomes creamy. Add kosher salt and freshly ground black pepper to taste. Blend 1–2 minutes until smooth but still vibrant.

Recipe FAQ

• Why is my pesto bitter? – Overprocessing greens or olive oil can release bitter compounds. Pulse just until combined to avoid a bitter taste.
• Is making your own pesto worth it? – Yes. Homemade pesto is fresher and more flavorful than most store-bought versions, and it takes only a few minutes to prepare.
• What is the best oil for pesto? – Extra virgin olive oil is preferred for its flavor and mouthfeel.
• Why is my pesto turning brown? – Oxidation causes browning. Store the pesto in an airtight container with a thin layer of olive oil on top to limit air exposure.
• Is pesto healthy? – Pesto is made from nutrient-dense ingredients: greens, nuts, olive oil, and cheese. Homemade versions let you control the salt and oil for a healthier result.

Storage

Store pesto in an airtight container in the refrigerator for up to five days. To prevent browning, smooth a thin layer of olive oil over the surface before sealing. For longer storage, freeze portions in an ice cube tray or small containers for up to six months; thaw as needed.

Top Tips

• If refrigerated, stir the pesto before using since separation can occur.
• Use a flexible spatula to scrape every last bit from the food processor bowl.
• Lightly toasting the walnuts first enhances their flavor but is optional.
