Ingredients
- 32 oz bag frozen fully cooked meatballs
- 12 oz bottle chili sauce
- 1 cup grape jelly
- 1 (20 oz) can pineapple chunks in juice, undrained
- 1 tbsp low-sodium soy sauce
- 2 tbsp cornstarch
- 2 tbsp cold water
Instructions
- Step 1: Whisk the chili sauce, grape jelly, and soy sauce in a slow cooker until the jelly breaks up and the sauce is smooth.
- Step 2: Stir in the frozen meatballs and the undrained pineapple chunks, mixing to coat evenly.
- Step 3: Cover and cook on low for 4 to 5 hours or on high for 2 to 3 hours, stirring halfway through. Cook until the meatballs are hot and the sauce has thickened slightly.
- Step 4: For a thicker glaze, whisk together the cornstarch and cold water in a small bowl. Stir this mixture into the slow cooker, then cook uncovered on high for an additional 15 to 30 minutes until the sauce thickens further. Serve warm.
Tips & Variations
- For extra tang, add a splash of rice vinegar or a squeeze of fresh lime juice to the sauce before cooking.
- Use homemade meatballs for a fresher taste, just adjust the cooking time accordingly.
- Include diced bell peppers or onions for added texture and flavor.
- If you prefer a less sweet sauce, reduce the amount of grape jelly slightly.
Storage
Store leftover meatballs and sauce in an airtight container in the refrigerator for up to 3 days. Reheat gently on the stove or in the microwave until warmed through, adding a splash of water if the sauce is too thick.

FAQs
Can I use fresh meatballs instead of frozen?
Yes, fresh or homemade meatballs can be used, but reduce the cooking time to avoid overcooking. Check that the meatballs are cooked through before serving.
How do I prevent the sauce from becoming too watery?
Cooking uncovered at the end with the cornstarch slurry helps thicken the sauce. You can also remove the lid in the last 30 minutes of cooking to allow some liquid to evaporate.
