Ingredients
Method
- In a large bowl, combine the ground beef, breadcrumbs, egg, garlic powder, diced onion, flour, salt, and pepper. Mix gently until just combined; overmixing can make the meatballs tough.
- Shape the mixture into small meatballs about 1.5 inches in diameter and gently place them into the slow cooker, leaving a bit of space between each.
- Whisk together soy sauce, brown sugar, rice vinegar, ketchup, and water in a separate bowl. Pour this sauce evenly over the meatballs.
- Tuck the pineapple chunks on top of the meatballs, allowing the sweet fruit to mingle with the sauce as it cooks.
- Cover and cook on low for 7 hours (420 minutes). The slow cooker will gently break down the meat while the sauce thickens into a glossy glaze.
- Before serving, stir the mixture gently to coat the meatballs in sauce, and use a food thermometer to verify that the internal temperature has reached a safe level for ground beef.
Notes
I fold in a tablespoon of flour to keep the meatballs from falling apart in the slow cooker, and I add a splash of soy sauce right before serving to deepen the sweetness. I also line the slow cooker with parchment to prevent sticking—my family says it saves a lot of cleanup.
Food Safety Note: Always use a food thermometer to confirm your dish has reached a safe internal temperature before serving, and follow your country’s official food safety guidelines for meat, poultry, and slow-cooking.
