How to Make Crock Pot Sweet and Sour Meatballs Recipe

Step 1: Prepare the Meatballs and Vegetables

Start by placing your frozen meatballs directly into the crock pot—no need to thaw! Then add the red and green bell peppers along with the chopped onion and pineapple chunks on top. This colorful mix not only makes the dish visually appealing but also creates layers of flavor and texture.

Step 2: Whisk Together the Sauce

In a large measuring cup or bowl, combine the juice from the pineapple can with the apple cider vinegar, brown sugar, granulated sugar, ketchup, soy sauce, and cornstarch. Whisk thoroughly until the sugars and cornstarch dissolve completely to ensure your sauce will thicken nicely during cooking.

Step 3: Pour Sauce Over the Meatballs

Pour this flavorful sauce evenly over the meatballs and vegetables in the crock pot. Use a spoon to gently stir and make sure everything is well coated with the sauce, setting the stage for those tender, melt-in-your-mouth bites.

Step 4: Slow Cook to Perfection

Cover your crock pot with the lid and set it to LOW. Let it cook for about 3-5 hours, giving it a stir halfway through to ensure everything cooks evenly. As it simmers, the sauce will thicken and the flavors will meld beautifully, creating an irresistible glaze that clings to each meatball.

Garnishes

Side Dishes

This recipe is fantastic on its own as an appetizer, but if you want a more substantial meal, serve the meatballs over steamed white rice or fluffy jasmine rice. The rice soaks up every bit of that delicious sauce, making each bite even more satisfying.

Creative Ways to Present

For a party, try serving these meatballs on toothpicks as finger food alongside a platter of fresh veggies. Alternatively, pile them onto slider buns for an irresistible sandwich version.

Make Ahead and Storage

Storing Leftovers

Once cooled, transfer any leftovers into an airtight container and store them in the refrigerator. They should keep well for 3 to 4 days, making for an easy next-day meal or snack.

Freezing

If you want to save this deliciousness for later, freeze the meatballs and sauce together in a freezer-safe container. They can keep for up to 3 months. Just thaw overnight in the fridge before reheating for the best texture and flavor.

Reheating

Reheat leftovers gently on the stovetop over low heat or in the microwave, stirring occasionally, until warmed through. Add a splash of water or broth if the sauce has thickened too much during storage—this will help bring it back to that perfect consistency.

FAQs

Can I use homemade meatballs for this recipe?

Absolutely! Homemade meatballs add a personal touch and fresh flavor, but be sure they’re fully cooked before adding them to the crock pot to prevent overcooking or drying out.

Is it possible to make this recipe gluten-free?
