Glossy, tangy-sweet sauce clinging to every tender Sweet & Sour Meatball and is the kind of thing that makes people hover around the snack table and quietly go back for thirds.
Preheat the oven to 400°F (200°C). Line a baking sheet with parchment paper.
In a large bowl, combine ground beef, breadcrumbs, egg, garlic, soy sauce, salt, and pepper.
Mix gently just until combined. Don’t overmix, or the meatballs can turn tough.
Roll into 1-inch meatballs and place them on the baking sheet. Make sure they aren’t touching. Bake for 12 minutes or until the meatballs reach an internal temperature of 165°F.
Meanwhile, add sauce ingredients to a small saucepan and stir to combine. Cook over medium heat for 3-5 minutes, until thickened.
When the meatballs are done, add them to a bowl. Pour the sauce over the meatballs and stir to combine.
