Ingredients
The star of the show is 2 pounds of frozen meatballs, which make this recipe wonderfully convenient, though homemade meatballs work beautifully if you have the time. Add 1 cup of pineapple chunks, and be sure to reserve the juice, since it goes right into the sauce. For color and a gentle crunch, you will need 1 red bell pepper and 1 green bell pepper, both diced.
The sweet and sour sauce comes together with pantry staples: 1/2 cup of ketchup for a tangy, rich base, 1/3 cup of brown sugar for caramel-like sweetness, and 1/4 cup of apple cider vinegar to provide that essential sour bite. Two tablespoons of soy sauce bring savory umami depth, while 1 teaspoon of garlic powder rounds everything out with a subtle aromatic kick.
If you like a thicker, glossier sauce that clings to every meatball, keep an optional cornstarch slurry on hand, made from 1 tablespoon of cornstarch mixed with 2 tablespoons of water. For an extra layer of warmth, a teaspoon of grated ginger stirred into the sauce pairs beautifully with the sweet and sour flavors.
Step-by-Step Instructions
Start by prepping your ingredients. Dice the red and green bell peppers into bite-sized chunks, and if you are using canned pineapple, drain it well while reserving the juice for the sauce. A little organization up front makes the rest of this recipe come together in minutes.
Next, make the sauce. In a bowl, whisk together the ketchup, reserved pineapple juice, brown sugar, apple cider vinegar, soy sauce, and garlic powder until smooth and well combined. Give it a quick taste and adjust if you like, keeping in mind the flavors will mellow and meld as they cook.
Now assemble everything in the crockpot. Add the frozen meatballs, diced bell peppers, and pineapple chunks, then pour the sauce over the top and gently stir to coat every piece. Set your crockpot to low for 4 to 5 hours or high for 2 to 3 hours, stirring occasionally if you happen to be nearby.
If you prefer a thicker, stickier sauce, mix the cornstarch with water to make a slurry and stir it in during the last 30 minutes of cooking. Once everything is hot and glossy, dish the meatballs up over steamed rice or fluffy mashed potatoes, or serve them as-is with toothpicks for an easy party snack.
Tips for the Best Sweet and Sour Meatballs
If you have the time, swapping frozen meatballs for fresh homemade ones adds an extra-special touch, though the frozen version is hard to beat for convenience. If you do not have cornstarch to thicken the sauce, simply let it cook uncovered for the last 30 minutes so it reduces and concentrates on its own.
For a little extra warmth, stir a teaspoon of grated ginger into the sauce, and if you like heat, a drizzle of sriracha or a pinch of red chili flakes gives it a spicy kick. These meatballs are fantastic over fried rice or noodles for a takeout-style twist. If you love easy crowd-pleasers, pair them with our crockpot enchilada casserole for game day, or serve alongside our Instant Pot pulled pork for a party spread that covers every craving.
