Preheat your oven to 400°F (200°C) and line a large baking sheet with parchment paper for easy cleanup.
In a large mixing bowl, combine the lean ground chicken, egg, almond flour, finely chopped parsley, dried oregano, minced garlic, sea salt, black pepper, and fresh lemon zest.
Using your hands or a wooden spoon, gently mix the ingredients together until just incorporated, taking care not to overwork the meat to ensure a light texture.
Lightly coat your palms with olive oil to prevent sticking, then roll the mixture into approximately 12 even-sized meatballs.
Arrange the meatballs on the prepared baking sheet, ensuring they are not touching so the heat can circulate evenly.
Bake for 15 to 18 minutes, or until the meatballs are golden on the outside and reach an internal temperature of 165°F.
Remove from the oven and let rest for 2 minutes before serving to allow the juices to redistribute.
