In a large bowl, combine ground chicken, ricotta cheese, breadcrumbs, Parmesan cheese, egg, garlic, Italian seasoning, salt, and black pepper. Mix well until fully incorporated.
Using your hands or a small scoop, form the mixture into evenly sized meatballs, about 1 to 1.5 inches in diameter. Place them on a lined baking sheet.
Preheat the oven to 400°F (200°C). Lightly drizzle olive oil over the meatballs. Bake for 20–25 minutes, or until the meatballs are golden brown and reach an internal temperature of 165°F (75°C). For extra crispiness, broil them for the last 2 minutes.
Remove from the oven and let them rest for a couple of minutes. Serve warm with pasta, marinara sauce, or on their own. For an extra flavorful dish, try them with Garlic Bread.
