Juicy, oven-baked Asian meatballs coated in a glossy pineapple soy glaze. A Korean-inspired twist on classic meatballs — sweet, savory, and perfect over steamed rice or veggies.
Preheat oven: Set to 375°F (190°C) and lightly grease or line a baking pan.
Make meatball mixture: In a large bowl, combine ground beef, mushrooms, bell pepper, green onion, garlic, rice flour, egg, salt, and pepper. Mix well until evenly combined and slightly sticky.Shape meatballs: Roll the mixture into balls about 1½ inches (4 cm) wide. Place evenly spaced on the prepared pan.Bake: Bake for 18–20 minutes, turning once halfway through, until golden brown and cooked through.
Prepare glaze: While meatballs bake, whisk together pineapple juice, soy sauce, garlic, ginger paste, sugar, rice vinegar, cornstarch, and mirim (if using).Cook glaze: Pour the glaze into a skillet and bring to a boil. Cook for 1–2 minutes, stirring, until the sauce thickens and becomes glossy.Combine and finish: Add the baked meatballs to the skillet and toss to coat evenly in the glaze. Sprinkle with toasted sesame seeds and serve hot over steamed rice or with sugar snap peas.
