Optional: 1/4 cup grated Parmesan cheese for a richerclassic pesto taste (omit if vegan)
For the Pasta
1pound454g pasta (your choice of shape)
Instructions
Cook the pasta according to the package instructions in salted water. Reserve 1 cup of pasta water before draining.
Blend the dry ingredients: In a food processor, add kale, walnuts, garlic, capers (if using), salt, and black pepper. Pulse several times until finely chopped.
Add liquid ingredients: While the food processor is running on low speed, slowly drizzle in the lemon juice and olive oil until the pesto reaches a smooth, creamy consistency. If using Parmesan, add it at this stage and blend until fully incorporated.
Adjust the seasoning: Taste and add more lemon juice, salt, or black pepper as needed. If the pesto is too thick, mix in a small amount of the reserved pasta water.
Toss with pasta: Combine the drained pasta with the pesto, adding a little pasta water as needed for a silky, well-coated dish.
Notes
Storage Tips: How to Keep Kale Pesto Fresh
Refrigerator: Store in an airtight container for up to 5 days. To prevent oxidation, drizzle a thin layer of olive oil on top.
Freezer: Freeze pesto in ice cube trays for individual portions. Once frozen, transfer the cubes to a bag and store for up to 3 months.
