01 - Bring a large pot of salted water to a boil over high heat.
02 - Add gnocchi and cook according to package directions until they float to the surface, approximately 2–3 minutes. Drain thoroughly and set aside.
03 - Heat olive oil in a large skillet over medium heat. Add chopped onion and sauté until translucent, about 3 minutes. Stir in minced garlic and cook for 1 minute until fragrant.
04 - Add baby spinach to the skillet and cook, stirring occasionally, until wilted, approximately 2 minutes.
05 - Pour in heavy cream and vegetable broth. Stir to combine and bring to a gentle simmer.
06 - Add crumbled feta and grated Parmesan. Stir continuously until cheese partially melts and sauce begins to thicken. Season with salt, black pepper, and nutmeg to taste.
07 - Gently fold in cooked gnocchi, tossing until thoroughly coated in sauce and heated through. Serve immediately, garnished with additional feta and black pepper if desired.
