01 - Spiralize the zucchinis using a spiralizer or julienne peeler. Pat dry thoroughly with paper towels to eliminate excess moisture.
02 - Combine basil leaves, pine nuts, Parmesan, and garlic in a food processor. Pulse until coarsely chopped.
03 - With the processor running, gradually add olive oil and lemon juice until a smooth paste develops. Season with salt and black pepper.
04 - Heat olive oil in a large skillet over medium heat. Add spiralized zucchini, salt, and pepper. Sauté for 2 to 3 minutes until just tender but retaining crispness.
05 - Remove skillet from heat. Add prepared pesto and toss with zucchini noodles until evenly coated.
06 - Portion noodles onto plates. Garnish with toasted pine nuts, additional grated Parmesan, and fresh basil leaves as desired. Serve immediately.
