01 - Bring a large pot of salted water to a boil. Cook the gnocchi according to package instructions until they float to the surface, approximately 2 to 3 minutes. Drain thoroughly and set aside.
02 - While the gnocchi cooks, melt the butter in a large skillet over medium heat. Add the minced garlic and sauté for 1 minute until fragrant, being careful not to brown it.
03 - Pour in the heavy cream and milk. Bring the mixture to a gentle simmer. Stir in the grated Parmesan cheese continuously until fully melted and the sauce becomes smooth and creamy.
04 - Add the fresh baby spinach to the skillet. Cook for 2 to 3 minutes, stirring frequently, until the spinach is completely wilted and incorporated into the sauce.
05 - Season the cream sauce generously with salt and freshly ground black pepper. Add the pinch of ground nutmeg if using to enhance the flavor depth.
06 - Add the cooked and drained gnocchi to the skillet. Toss gently to coat each piece evenly with the creamy spinach sauce. Let everything heat through for 1 to 2 minutes. Serve immediately, garnished with extra grated Parmesan and freshly cracked black pepper.
