How to Make Sweet and Sour Meatballs
Step 1: Prepare the Pineapple Juice
First, drain the juice from the can of pineapple into a medium bowl. Set the pineapple chunks aside; you will use them later in the recipe. Make sure to reserve the juice for the sauce.
Step 2: Add Meatballs to the Crock Pot
Place the frozen meatballs directly into a 4-6 quart crock pot. Arrange them evenly at the bottom for even cooking.
Step 3: Layer the Vegetables
Top the meatballs with the reserved pineapple chunks and the diced green pepper. This layering adds flavor to the dish as it cooks.
Step 4: Whisk the Sauce Ingredients
In the bowl with the reserved pineapple juice, whisk together the brown sugar, vinegar, soy sauce, and cornstarch. Mix until everything is well combined and there are no lumps.
Step 5: Pour Sauce Over Meatballs
Pour the sauce mixture evenly over the meatballs and vegetables in the crock pot. Make sure all ingredients are covered with the sauce.
Step 6: Cook on Low
Cover the crock pot and set it to low for 2 hours. During this time, the flavors will meld together beautifully.
Step 7: Switch to High Heat
After 2 hours, switch the crock pot to high and cook for an additional hour. The sauce should thicken and start bubbling around the edges when done.
Step 8: Serve and Enjoy
Once cooked, serve the meatballs over rice or enjoy them as an appetizer. You can garnish with extra pineapple or green pepper if desired.
