Savory meatball appetizers in a sweet and tangy glaze are a high protein, family-favorite party bite. These easy, crowd-pleasing bites are perfect for entertaining and game day.
Preheat your oven to 400°F. Line a rimmed baking sheet with parchment paper for even browning and easy cleanup.
In a large mixing bowl, combine ground beef, breadcrumbs, egg, milk, parmesan, onion, kosher salt, black pepper, and garlic powder. Mix gently until just combined and moist but not dense.
Shape the mixture into 1-inch meatballs and arrange evenly on the prepared baking sheet, spacing to prevent steaming. Bake for 15–18 minutes, until browned and cooked through.
While the meatballs bake, make the glaze: In a saucepan over medium heat, whisk together ketchup, brown sugar, apple cider vinegar, and Worcestershire sauce. Simmer for 4–5 minutes, stirring, until glossy and slightly thickened.
Transfer baked meatballs to a clean serving bowl. Pour hot glaze over and toss gently to coat each meatball. Serve immediately, keeping warm if desired for parties.
