I started leaning on this recipe hard last spring when weeknights felt like a blur and I just needed something that worked without much thought. The first time I tested it for the blog, I remember opening the slow cooker lid around hour three and getting hit with that perfect balance of pineapple and vinegarit smelled like a takeout night, but better.

Crock Pot Sweet and Sour Meatballs Easy Weeknight Dinner
This Crock Pot Sweet and Sour Meatballs recipe is a fantastic easy dinner option that’s perfect for a busy weeknight meal or a comforting family dinner. Featuring tender slow cooker meatballs smothered in a homemade sweet and sour sauce with pineapple and green peppers, this sweet and sour recipe is flavorful and fuss-free.
20 ounce can pineapple chunks in 100% juice (save juice)
1 green pepper diced into chunks
1 cup brown sugar
⅔ cup vinegar
2 tablespoon soy sauce
3 tablespoon cornstarch
Method
Pour the pineapple juice from the can into a medium bowl and set aside about a cup for the sauce.
Add the frozen meatballs to a 4-6 quart crock pot.
Scatter the pineapple chunks and diced green pepper over the meatballs.
Whisk together the reserved pineapple juice with brown sugar, vinegar, soy sauce, and cornstarch until smooth.
Pour the sauce mixture evenly over the meatballs and cover the crock pot.
Cook on the low setting for 2 hours.
Switch the crock pot to high and continue cooking for 1 more hour to thicken the sauce, which should be bubbling and thick around the edges when done.
Notes
The meatballs can be added directly from frozen; no need to thaw. Feel free to omit the peppers if you prefer. This recipe works with most standard size frozen meatball bags except family size. If your pineapple juice yield is less than a cup, add a little water to make up the difference. Serve with rice for a full meal or offer as an appetizer with toothpicks.

How to Serve and Store
Serve these meatballs warm, straight from the crock pot. For a full meal, spoon them over a bowl of fluffy white rice so the sauce soaks in. For appetizers or gatherings, set out toothpicks and let guests help themselves.
Leftovers keep well in an airtight container in the fridge for up to three days. Reheat gently on the stove or in the microwavethe sauce may thicken up even more, which just makes it cling better to the meatballs.
Pro Tip: If the sauce gets too thick after storing, stir in a tablespoon or two of water when reheating to loosen it back up.

FAQs (Crock Pot Sweet and Sour Meatballs)
Can I use frozen meatballs for this recipe?
Yes, frozen meatballs work perfectly and save time. Add them directly to the slow cooker without thawing first. They’ll cook through completely in the sauce and absorb all the flavors beautifully.
How long should I cook this dish on high vs low?
Cook on low for 4-6 hours or high for 2-3 hours. Low heat gives the best texture and prevents the sauce from getting too thick. High heat works when you’re short on time but stir occasionally.
What if my sauce is too thin or thick?
For thin sauce, mix 1 tablespoon cornstarch with 2 tablespoons cold water and stir into the pot during the last 30 minutes. For thick sauce, add a splash of pineapple juice or water.
Can I make homemade meatballs instead?
Absolutely! Brown homemade meatballs in a skillet first to prevent them from falling apart in the slow cooker. Use ground beef, pork, or a mixture for the best flavor and texture.
What should I serve with this meal?
Serve over steamed white rice, brown rice, or egg noodles to soak up the delicious sauce. Add steamed broccoli or snap peas on the side for a complete, balanced dinner.
