01 - Combine basil leaves, pine nuts, Parmesan cheese, and garlic in a food processor. Pulse until finely chopped. With the motor running, slowly drizzle in the olive oil. Add salt, pepper, and lemon juice, then blend until smooth. Taste and adjust seasoning as needed.
02 - Bring a large pot of salted water to a rolling boil. Add gnocchi and cook according to package directions until they float to the surface, typically 2–3 minutes. Drain thoroughly, reserving 1/4 cup of the cooking water for later use.
03 - While the gnocchi cooks, heat 1 tablespoon olive oil in a large skillet over medium heat. Add baby spinach and sauté for 1–2 minutes until just wilted but still bright green.
04 - Add the drained gnocchi to the skillet with the wilted spinach. Pour in the prepared pesto sauce along with a splash of the reserved cooking water. Toss gently until everything is evenly coated and the sauce clings to the gnocchi.
05 - Divide the gnocchi among four serving plates. Top generously with additional grated Parmesan cheese and a fresh grind of black pepper. Serve immediately while hot.
