These Crock Pot sweet and sour meatballs are made with frozen meatballs, juicy pineapple, crisp bell peppers, and a tangy homemade sauce. Just add everything to your slow cooker, let it simmer, and serve over rice, noodles, or as a party appetizer.
Add meatballs and cornstarch to a 1 gallon freezer bag. Shake until completely coated.
Place coated meatballs, green pepper, red pepper, and onion to the slow cooker.
In a medium bowl add juice from pineapple chunks, brown sugar, apple cider vinegar, ketchup, Worcestershire sauce, soy sauce, and garlic. Stir together and pour over meatballs and vegetables.
Cover and cook on high for 2½ hours (or low for 4½ to 5½ hours). 30 minutes before the cooking time is complete, add in the pineapple chunks and recover, and finish cooking.
Serve over rice and garnish with fresh green onions and sesame seeds. Enjoy!
Notes
Coating the frozen meatballs in cornstarch before cooking helps the sauce stick and creates a glossy finish.
Add pineapple chunks during the last 30 minutes of cooking so they keep their texture and don’t turn mushy.
Avoid stirring too often while cooking to keep the meatballs from breaking apart.
