Ingredients You’ll Need

2 pounds frozen meatballs: These minimal-fuss meatballs are perfect for soaking up the sauce. Make sure to choose quality ones for the best flavor.
2 bell peppers (any color): They add a crunchy texture and a touch of sweetness. Feel free to mix colors for an attractive dish!
½ white onion: For a subtle sweetness that complements the other ingredients. You can substitute with yellow onion if needed.
20 oz can pineapple chunks in juice: The star of the sauce, it provides sweetness and acidity, ensuring the perfect balance. Avoid syrup-packed options for a healthier twist.
½ cup brown sugar: This gives the sauce its rich sweetness. If you want a lighter version, you could substitute with coconut sugar.
½ cup rice vinegar: It introduces essential tanginess to the dish. If unavailable, apple cider vinegar can work as a substitute.
¼ cup ketchup: Adds depth and rounds out the sauce nicely. Look for a brand with natural ingredients for cleaner flavor.
2 tablespoons soy sauce: A dash enhances the umami notes in the meatballs. Use low-sodium soy sauce if you’re watching your salt.
2 tablespoons cornstarch: This thickens the sauce, giving it that luscious consistency we all love.

How to Make Slow Cooker Sweet And Sour Meatballs

Add Meatballs: Begin by placing the 2 pounds of frozen meatballs into the bottom of your slow cooker, spreading them evenly. This forms the base for your flavorful dish.
Prep the Peppers: Remove the ribs and seeds from the 2 bell peppers, then chop them into chunks. Toss them directly into the slow cooker alongside the meatballs.
Onion Assembly: Peel the ½ white onion and cut it into chunks. Add these onion pieces to the mix for added sweetness and flavor.
Drain Pineapple Juice: Carefully drain the juice from the 20 oz can of pineapple chunks. Keep this juice aside, as it will be vital for your sauce.
Add Pineapple: Pour the pineapple chunks into the slow cooker, nestling them around the meatballs and veggies.
Prepare the Sauce: In a mixing bowl, whisk together the reserved pineapple juice, ½ cup brown sugar, ½ cup rice vinegar, ¼ cup ketchup, and 2 tablespoons of soy sauce. The aroma will be irresistible!
Thicken the Sauce: Mix the 2 tablespoons of cornstarch with 2 tablespoons of water until smooth to create a slurry. Whisk this into your pineapple juice mixture, ensuring it’s fully combined.
Combine & Cook: Pour the sauce over the meatballs and veggies in the slow cooker. Stir gently to coat everything evenly.
Cover & Cook: Finally, cover your slow cooker and let it do its magic. Cook on high for 2–3 hours or on low for 4–6 hours, until everything is heated through and the sauce has thickened. You’ll know it’s done when the edges bubble delightfully.

Storing & Reheating

If you have leftovers, let them cool down to room temperature before transferring them into airtight containers. They can be stored in the refrigerator for up to 4 days. For longer storage, freeze your meatballs in sauce for up to 3 months. When you’re ready to enjoy again, simply reheat in the microwave or on the stove over low heat until warmed through. Just remember, the texture might slightly change after freezing, but you can revive the flavors by adding a splash more soy sauce or rice vinegar if needed!

Chef’s Helpful Tips

Avoid overcooking the meatballs; keep an eye on them as cooking times can vary based on your slow cooker model.
For extra depth of flavor, consider adding minced garlic or ginger to the sauce mixture.
If your sauce isn’t thickening, make an additional cornstarch slurry and add it gradually.
For a touch of heat, toss in some red pepper flakes or sriracha to your sauce.
You can make this recipe ahead of time; just prep and assemble everything in the slow cooker, store it in the fridge, and cook it whenever you’re ready.
