01 - Bring a large pot of salted water to a boil. Add the gnocchi and cook according to package instructions until they float, about 2–3 minutes. Drain and set aside.
02 - Heat the butter and olive oil in a large skillet over medium heat. Add the chopped onion and cook until translucent, about 3 minutes.
03 - Stir in the minced garlic and cook for 30 seconds until fragrant.
04 - Add the fresh spinach and sauté until just wilted, 1–2 minutes.
05 - Reduce heat to low. Pour in the heavy cream, add ground nutmeg, and stir. Cook gently for 2–3 minutes until the sauce thickens slightly.
06 - Stir in the grated Parmesan until melted and smooth. Season with salt and freshly ground black pepper to taste.
07 - Add the drained gnocchi to the sauce and toss gently to coat evenly. Warm through for 1–2 minutes.
08 - Plate immediately and garnish with extra grated Parmesan and freshly cracked black pepper.
