Ingredients for Sweet and Sour Meatballs

Meatballs – Frozen or fresh pre-cooked meatballs. Any meatball will work here. If planning to serve as an appetizer, then I would suggest using it as mini cocktail meatballs.
Pineapple Juice– I prefer using reserved pineapple juice from a can. You can also use fresh or packed juice. if you are using pineapple juice other than a can and it is sour, then adjust the amount of sugar to balance the sauce.
Tomato Ketchup
Brown Sugar
Soy Sauce
Apple cider vinegar
Vegetable oil – Any neutral flavor
Garlic – Minced
Cornstarch – to thicken the sauce

Steps To Make

Assuming you are using pre-cooked meatballs, this recipe starts with making the sauce. Saute garlic in oil until aromatic.
Then add the rest of the ingredients to the pan except cornstarch and meatballs. Let the sauce come to a low boil. Make a slurry of cornstarch and water. Gradually stir in the slurry until it mixes completely.
Next, step is to add the meatballs. If using freshly cooked meatballs, add to the skillet and keep cooking on medium-high heat for the sauce to thicken completely. The sauce should coat the meatballs really well.
For frozen meatballs, you really don’t have to thaw them. Add directly the frozen ones to the skillet. Lower the heat and cook covered for 10-12 minutes. The meatballs should cooked through. Add a couple of tablespoons of water if the sauce has thickened and starts sticking to the bottom of the skillet.

Can we make it in a Slow Cooker?

These can easily made in a slow cooker. In fact, if you are planning to make these for a party, then this would be completely hands-off. In a crock pot add all the ingredients except meatballs. Let the sauce cook for an hour on high. Then add frozen meatballs and cook for another 2 hours until the meatballs are cooked through and the sauce has thickened.
