01 - Bring a large pot of salted water to a boil. Cook the penne according to package instructions until al dente. Drain, reserving 1/2 cup of pasta water.
02 - Heat olive oil in a large skillet over medium heat. Add minced garlic and sauté for 1 minute until fragrant.
03 - Add the chopped spinach and cook until wilted, about 2 minutes. Stir in the quartered artichoke hearts and cook for an additional 2 minutes.
04 - Reduce heat to low. Add softened cream cheese and stir until melted and evenly combined with the vegetables.
05 - Pour in heavy cream, grated parmesan, lemon zest, and ground nutmeg. Stir continuously until the sauce becomes smooth and slightly thickened, approximately 3 to 4 minutes.
06 - Season the sauce with salt and freshly ground black pepper. Add the cooked penne to the skillet and toss to coat thoroughly. Incorporate reserved pasta water as needed to adjust sauce consistency.
07 - Serve immediately, garnished with extra grated parmesan cheese and freshly ground black pepper.
