Preheat oven to 400°F (200°C). Line a baking sheet with parchment paper.
In a large bowl, combine all ingredients. Mix gently until just combined to avoid overmixing.
Using wet hands, form mixture into 1-inch meatballs and place on the prepared baking sheet, leaving a little space between each.
Optional: use a basting brush to brush olive oil on top of each meatball. This will help to brown/caramelize them a bit!
Bake for 15 minutes, or until meatballs reach an internal temperature of 165°F (74°C) and are lightly browned.
Spoon marinara sauce evenly over the ground chicken meatballs before serving, or allow to cool completely before portioning into containers for meal prep.
Serve as desired. They're great over cooked pasta, rice, or in rolls for meatball subs.
Notes
This recipe yields about 30 (1-inch) meatballs. Larger meatballs will take longer to cook through.
Be sure to use an instant-read meat thermometer to ensure that the ground chicken meatballs are cooked through to an internal temperature of 165°F.
Lightly wetting your hands with water prevents the meatball mixture from sticking to your hands.
Fully baked meatballs will keep for up to 5 days in the fridge, or freezer for up to 3 months. Reheat meatballs to an internal temperature of 165°F. before consuming.
