Preheat your oven to 375°F, then line a baking sheet with parchment paper and set aside. While the oven preheats, add all the ingredients to a large bowl aside from the oil and 1 tablespoon of green onions.
Mix the meatball mixture with a spoon or clean hands until fully integrated.
Using a Tablespoon measure, spoon our 2 Tablespoons of meatball mixture at a time and roll into a ball. If they don't roll well, add more panko. Place the meatballs on the baking sheet.
Brush the tops of the raw meatballs with olive oil using a pastry brush.
Place the baking sheet in the oven, and bake for 25-30 minutes until browned and the interior reaches 160°F.
Remove from the oven, brush with more sauce, and serve! Mix ¼ cup Hoisin sauce with 3 Tablespoons water for a tasty dip, if desired.
Notes
If you're making these meatballs as a party appetizer, make them half-size with only one Tablespoon of mix per meatball.
These meatballs are make-ahead friendly! Just roll them out and freeze them on a baking sheet for 3-4 hours, then transfer them to a bag or sealed container. They will last 2-3 months and can be cooked from frozen- just check the interior temperature carefully and add more time!
Make sure you use panko breadcrumbs! They look similar to regular, but are fluffier and lighter in texture, making for a less dense meatball.
To make this appetizer into an incredible dinner, just serve it up with extra sauce, white rice, and your favorite vegetables! I love adding stir fried onions, peppers, mushrooms and broccoli.
