Bring a large pot of salted water to a vigorous boil. Add the gnocchi and cook according to package instructions, usually around 2-3 minutes, or until they rise to the surface. Drain and set aside.
In a large skillet, warm the olive oil over medium heat. Add the minced garlic and sauté for about 30 seconds until aromatic and lightly golden.
Add the chopped spinach to the skillet and stir into the garlic-infused oil. Cook for approximately 2-3 minutes until wilted. If using, add the sun-dried tomatoes and mix thoroughly.
Reduce heat to low and pour in the heavy cream. Stir gently as it simmers. Gradually add the Parmesan cheese and nutmeg, mixing until the cheese melts and the sauce is creamy. Season with salt and pepper to taste.
Gently fold the cooked gnocchi into the creamy spinach sauce, tossing to coat evenly and heat through for an additional 2-3 minutes.
Distribute the creamy spinach gnocchi onto individual plates. Garnish with additional cracked black pepper and Parmesan cheese if desired.
Notes
Serve in shallow bowls and garnish with fresh herbs and garlic bread.
