Preheat the oven to 400°F (200°C).

In a mixing bowl, combine ground chicken, breadcrumbs, Parmesan cheese, egg, minced garlic, lemon zest, parsley, salt, and pepper.

Mix until just combined, being careful not to overmix.

Form the mixture into meatballs, about 1 inch in diameter.

Place the meatballs on a baking sheet lined with parchment paper.

Bake the meatballs in the preheated oven for 20-25 minutes, or until cooked through and golden brown.

While the meatballs are baking, prepare the lemon garlic sauce by combining chicken broth, lemon juice, olive oil, minced garlic, and parsley in a small skillet over medium heat.

Simmer for 5-7 minutes until slightly thickened.

Once the meatballs are done, remove them from the oven and drizzle with the lemon garlic sauce.

Serve warm, garnished with additional parsley if desired.
