Preheat the oven to 400°F (200°C).
In a large mixing bowl, combine ground chicken, ricotta cheese, Parmesan cheese, breadcrumbs, egg, minced garlic, oregano, salt, black pepper, and parsley. Mix well until all ingredients are incorporated.
Form the mixture into meatballs, about 1.5 inches in diameter, and place on a lightly greased baking sheet.
Bake meatballs in the preheated oven for 20 minutes or until cooked through and browned.
While the meatballs are baking, prepare the Spinach Alfredo sauce. In a sauté pan, heat olive oil over medium heat. Add chopped spinach and sauté until wilted, about 2 minutes.
In a saucepan, add heavy cream and bring to a gentle simmer. Whisk in grated Parmesan cheese, garlic powder, salt, and pepper until well combined and smooth.
Stir in the sautéed spinach and cook for another 2-3 minutes until heated through.
Once the meatballs are done, add them to the Spinach Alfredo sauce and gently coat all meatballs with the sauce.
Serve the chicken ricotta meatballs with extra grated Parmesan, if desired.
