Preheat your oven to 200°C (400°F). Line a baking sheet with parchment paper.
In a large bowl, combine the ground chicken, ricotta cheese, beaten egg, breadcrumbs, chopped parsley, lemon zest, garlic powder, salt, and pepper. Mix gently until just combined. Be careful not to overmix.
Roll the mixture into meatballs, about 2.5-3 cm (1 inch) in diameter. Place them on the prepared baking sheet.
Bake for 20-25 minutes, or until the meatballs are cooked through and golden brown. The internal temperature should reach 74°C (165°F).
Serve hot, garnished with lemon wedges and extra chopped parsley, if desired. These are great on their own or served with pasta, rice, or a salad.
Notes
For a slightly crispy exterior, you can pan-sear the meatballs for a few minutes on each side before baking.
