01 - Bring a large pot of salted water to a rolling boil. Add the gnocchi and cook according to package directions until they float to the surface, approximately 2-3 minutes. Drain thoroughly in a colander 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 about 1 minute until fragrant, being careful not to brown it.
03 - Pour in the heavy cream and milk, bringing the mixture to a gentle simmer. Gradually whisk in the grated Parmesan cheese, stirring continuously until completely melted and the sauce becomes smooth and velvety.
04 - Add the fresh baby spinach to the simmering sauce. Cook for 2-3 minutes while stirring constantly until the spinach is completely wilted and incorporated into the sauce.
05 - Add salt, freshly ground black pepper, and nutmeg to taste. Stir well to distribute the seasonings evenly throughout the sauce.
06 - Add the cooked, drained gnocchi to the skillet. Gently toss to coat each piece thoroughly in the creamy sauce. Allow everything to heat through for 1-2 minutes. Serve immediately, garnished with additional grated Parmesan and freshly cracked black pepper.
