Ingredients for Sweet and Sour Meatballs

• Apple cider vinegar – this gives the sauce that sour flavor! It’s from the tang and zing of the vinegar.
• Light brown sugar – this gives the sauce the sweet flavor and a molasses-y depth of flavor.
• Ketchup – helps sweeten up the sauce as well and gives it color.
• Soy sauce – brings the umami in the sauce.
• Red pepper flakes – add more if you want it spicier!
• Cajun seasoning – this gives it a boost in spice and smokiness.
• Cornstarch – helps thicken up the sauce.
• Water
• Pre-cooked frozen meatballs – I used turkey meatballs but you can choose whatever kind you like.
• Pineapple chunks – fresh or canned. If using canned, drain most of the liquid before pouring into the slow cooker. The extra juice is definitely nice to add to the sauce!
• Cilantro or parsley – for garnish.

How to Make Sweet and Sour Meatballs Step by Step

• Make the sauce. In a saucepan over medium-high heat, combine apple cider vinegar, brown sugar, ketchup, soy sauce, red pepper flakes, and cajun seasoning. In a separate small bowl, mix cornstarch and water, then add to the saucepan. Whisk often until the sauce starts to thicken, about 10 minutes.

• Bring together the dish. Add the frozen meatballs and pineapple chunks to the insert of the slow cooker. Pour the sauce all over then cover and cook on low for 4 hours or high for 2 hours.

Sweet and Sour Meatball Variations

• Add vegetables. Adding in chopped red and orange bell peppers would make this dish so colorful and even more flavorful!

• Make your own meatballs. You can make your own meatballs for this dish if you’d like. Try these chicken meatballs or turkey meatballs. Feeling vegetarian? These tofu meatballs would be great in this dish as well!
