01 - Bring a large pot of salted water to a boil. Add gnocchi and cook until they float to the surface, about 2 to 3 minutes. Drain and set aside.
02 - In a large skillet over medium heat, melt butter with olive oil. Add shallot and sauté until translucent, about 2 minutes. Add garlic and cook until fragrant, about 30 seconds.
03 - Add spinach to the skillet and cook, stirring, until wilted, approximately 2 minutes.
04 - Pour in heavy cream and bring to a gentle simmer. Stir in nutmeg, salt, and pepper.
05 - Add cooked gnocchi to the skillet and toss to coat thoroughly. Stir in Parmesan cheese and cook for 1 to 2 minutes until the sauce thickens and gnocchi are heated through.
06 - Taste and adjust seasoning if necessary. Serve immediately, garnished with extra Parmesan, fresh basil leaves, and cracked black pepper if desired.
