Preheat the oven to 400°F (200°C).
In a bowl, combine ground chicken, ricotta, Parmesan, parsley, garlic powder, Italian seasoning, salt, and pepper.
Form the mixture into meatballs, about 1 to 1.5 inches in diameter.
Place the meatballs on a baking sheet lined with parchment paper.
Bake for 20-25 minutes until golden brown and cooked through.
While the meatballs are baking, prepare the creamy spinach Alfredo.
In a saucepan, add spinach and sauté until wilted.
Stir in the heavy cream and chicken broth, then bring to a simmer.
Add baked meatballs to the sauce and let simmer for a few minutes.
Serve over cooked fettuccine if desired.
