Preheat the Oven: Preheat your oven to 375°F (190°C). Line a baking sheet with parchment paper or lightly grease it with olive oil.
- Prepare the Zucchini: Grate the zucchini and squeeze out the excess moisture using a kitchen towel or cheesecloth.
- Make the Meatball Mixture: In a large bowl, combine the ground chicken, grated zucchini, Parmesan cheese, breadcrumbs, chopped parsley, egg, minced garlic, oregano, salt, and pepper. Mix until well combined, but don’t overmix.
- Form the Meatballs: Shape the mixture into small meatballs, about 1 to 1 1/2 inches in diameter. Place them on the prepared baking sheet, ensuring they are evenly spaced.
- Bake the Meatballs: Drizzle or spray the meatballs with olive oil for crispiness. Bake in the preheated oven for 20-25 minutes, until golden brown and cooked through (internal temperature should reach 165°F or 74°C).
- Serve: Let the meatballs cool slightly before serving. Serve with marinara sauce and pasta, on a sandwich, or as a healthy appetizer with a dipping sauce.
