Sweet and sour is one of my favorite types of meals. There are just so many variations that you’re able to do. This recipe takes you through the steps to making a delicious meatball dish.

This dish looks quite complicated because we need to make the meatballs and the sweet and sour sauce from scratch. You can always prepare this dish a bit faster by buying pre-packed varieties such as frozen meatballs or packet sauce. The downside to packet food is that it doesn’t nearly taste as good and typically contains lots of additives.

If you have a bit of extra time towards the end of cooking, then you should certainly try this dish with some rice, noodles or anything else you feel like having with it.

Recipe Tips

  • As with any type of slow cooking you don’t need to fry off the meatballs before adding it to the slow cooker. However, you may notice a difference in taste and texture. The meatballs, in this case, may fall apart if you don't brown them beforehand.
  • You can add more vegetables to the sweet and sour sauce if you’re looking to add more to this dish. Button mushrooms, water chestnuts are just a couple of great vegetables that you’re able to add to this delicious recipe.
  • If you don’t mind a super runny sauce, then you don’t need to add the cornstarch. Unfortunately, one side effect of slow cookers is their tendency to be very soupy because the cooking method doesn’t allow moisture to evaporate.
  • You can swap out the beef mince for a different type of meat. For example, pork or even chicken will go well in this dish, but it’s entirely up to you.
