01 - Bring a large pot of salted water to a rolling boil. Add the gnocchi and cook until they float to the surface, approximately 2 to 3 minutes. Drain well and set aside.
02 - Heat olive oil and butter in a large skillet over medium heat. Add the chopped onion and cook for 3 to 4 minutes until translucent.
03 - Incorporate the minced garlic into the skillet and cook for 30 seconds until fragrant.
04 - Pour in the heavy cream and bring to a gentle simmer. Stir in the nutmeg, salt, and black pepper.
05 - Add the baby spinach and cook for 2 to 3 minutes, stirring occasionally, until wilted.
06 - Add the drained gnocchi to the skillet and gently toss to coat evenly. Sprinkle with Parmesan cheese and stir until the cheese melts and the sauce thickens slightly.
07 - Adjust seasoning as needed and serve immediately, optionally garnished with extra Parmesan cheese.
