Why This Recipe Works (Quick Science)
The crockpot slowly heats the meatballs, which helps them stay juicy instead of drying out. The sweet and sour sauce thickens as it cooks and coats every meatball evenly. The sugar in the sauce caramelizes slightly over time, giving the sauce a richer flavor. Pineapple adds natural sweetness and a little acid, which balances the savory barbecue sauce.
Instructions
Step 1: Add the Meatballs and Vegetables
Place 32 ounces frozen fully cooked meatballs into the black oval crockpot. Add 1 cup drained pineapple chunks, 1 diced green bell pepper, and 1 diced onion.
Step 2: Mix the Sauce
In a small bowl, stir together 1 cup sweet and sour sauce, 1/2 cup barbecue sauce, 2 tablespoons soy sauce, 1 tablespoon brown sugar, and 1 teaspoon garlic powder until smooth.
Step 3: Pour the Sauce Over the Meatballs
Pour the sauce mixture over the frozen meatballs, diced green bell pepper, diced onion, and pineapple chunks. Stir gently until everything is coated.
Step 4: Slow Cook
Cover the crockpot with the lid. Cook on LOW for 4 hours or HIGH for 2 hours until the meatballs are hot and the sauce is bubbling.
Step 5: Garnish and Serve
Top the meatballs with 2 sliced green onions and 1 teaspoon sesame seeds before serving.
Common Mistakes
- Using too much pineapple juice can thin the sauce.
