Creating Baked Chicken Ricotta Meatballs with Spinach is simple if you follow these steps:

1. Preheat the Oven: Preheat your oven to 400°F (200°C). Line a baking sheet with parchment paper for easy cleanup.
2. Combine Ingredients: In a large mixing bowl, combine the ground chicken, ricotta cheese, chopped spinach, Parmesan cheese, breadcrumbs, egg, parsley, garlic, onion powder, salt, black pepper, and red pepper flakes.
3. Mix Well: Use your hands or a spatula to mix all ingredients thoroughly until well combined.
4. Form Meatballs: Using your hands, scoop a portion of the mixture and roll it into a meatball, about 1.5 inches in diameter. Place on the prepared baking sheet.
5. Spray with Olive Oil: Lightly spray the meatballs with olive oil to help them brown during baking.
6. Bake: Place the baking sheet in the preheated oven and bake for 25-30 minutes, or until the meatballs are cooked through and golden brown.
7. Check for Doneness: Use a meat thermometer to ensure the internal temperature reaches 165°F (75°C).
8. Warm Marinara Sauce: While the meatballs are baking, warm the marinara sauce in a small pot over low heat.
9. Serve: Once the meatballs are done, remove them from the oven and let them rest for a few minutes before serving.
