Prep the Gnocchi: Boil a pot of salted water over medium heat. Once boiling, gently add the gnocchi and cook according to the package instructions until they float to the top (about 2-3 minutes). Drain and let them cool slightly before proceeding.
Mix the Pumpkin Sauce: In a mixing bowl, combine the pumpkin puree, olive oil, chopped fresh sage, garlic powder, salt, black pepper, and red pepper flakes (if using). Mix until well combined.
Coat the Gnocchi: Gently fold the cooked gnocchi into the pumpkin mixture until each piece is well coated.
Preheat the Air Fryer: Preheat your air fryer to 375°F (190°C) for about 5 minutes.
Air Fry the Gnocchi: Lightly spray the air fryer basket with cooking spray to prevent sticking. Transfer the coated gnocchi to the air fryer basket in a single layer, ensuring they are not overcrowded. You may need to do this in batches. Air fry for 10-12 minutes, shaking the basket halfway through, until the gnocchi are golden brown and crispy.
Serve: Once done, remove the gnocchi from the air fryer and plate them. Sprinkle with grated Parmesan cheese and garnish with fresh sage leaves. Drizzle with a little extra olive oil if desired.
