Why Kale Makes This Dish Special
Kale gives this dish its signature bold green hue and nutrient-dense power. Beyond its stunning color, it’s a nutritional gem—rich in vitamin K, vitamin C, calcium, and antioxidants.

When paired with olive oil and nuts, these nutrients become more easily absorbed, turning a simple meal into a nourishing powerhouse.
The mild bitterness of kale contrasts beautifully with the nuttiness of toasted walnuts, while fresh lemon juice and parmesan bring brightness and balance.
The combination creates a pesto that’s creamy but not heavy—perfect for anyone looking for a flavorful yet guilt-free pasta.
Ingredients You’ll Need
- 12 oz spaghetti (or any long pasta like linguine or bucatini)
- 4 cups kale leaves, stems removed
- ½ cup toasted walnuts
- ½ cup grated parmesan cheese (or nutritional yeast for vegan option)
- 2 garlic cloves, peeled
- ½ cup extra-virgin olive oil
- Juice and zest of 1 lemon
- Salt and pepper, to taste
- ½ cup reserved pasta water
Optional enhancements: a pinch of red pepper flakes for gentle heat, or a handful of fresh basil or parsley to soften kale’s intensity.
Step-by-Step Preparation
1. Toast the walnuts for maximum flavor
Place walnuts in a dry pan over medium heat and stir frequently until fragrant and slightly darkened. This simple step amplifies their flavor and deepens the pesto’s richness.
2. Cook your pasta
Boil spaghetti in salted water until al dente. Salt generously—this is your first chance to season the dish. Before draining, save ½ cup of pasta water. The starchy liquid will help emulsify and loosen the pesto later.
3. Prepare the kale pesto
In a food processor, combine kale, toasted walnuts, garlic, parmesan, lemon juice, and zest. Pulse several times until coarsely chopped. With the motor running, drizzle in the olive oil slowly. Continue blending until smooth and creamy.
4. Adjust consistency and seasoning
Add a few tablespoons of the reserved pasta water to thin the sauce to your liking. Taste and season with salt, black pepper, or extra lemon juice for brightness.
5. Combine and serve
Toss the spaghetti directly into the pesto, mixing thoroughly to coat each strand. Serve immediately with extra grated parmesan, a drizzle of olive oil, or a sprinkle of chili flakes if you enjoy a little spice.
Chef’s Tips for Success
- Blanch the kale for 30 seconds in boiling water if you prefer a milder, less bitter flavor. It also helps the pesto keep its vibrant green color.
- Reserve pasta water every time you make a sauce—its starch is key to a silky finish.
- For a richer texture, add a spoonful of ricotta or Greek yogurt before tossing.
- Prefer a vegan version? Use nutritional yeast or vegan parmesan and reduce the olive oil slightly for balance.
- To make it heartier, top with grilled chicken, pan-seared shrimp, or roasted chickpeas for added protein.
Storage, Freezing, and Reheating
Homemade pesto keeps beautifully when stored properly.
- In the fridge: Store in an airtight jar with a thin layer of olive oil on top to prevent browning. It will stay fresh for 3–4 days.
- In the freezer: Spoon pesto into ice cube trays, freeze, then transfer cubes to a sealed container. They’ll last up to 3 months—just thaw and toss into hot pasta anytime.
- Reheating tip: Warm gently on low heat with a splash of water or extra olive oil. Avoid high heat to preserve the pesto’s fresh, green flavor.
Flavor Variations You’ll Love
