Equipment

  • Slow Cooker

Ingredients

  • 2 pounds frozen meatballs
  • 2 bell peppers any color
  • ½ white onion
  • 20 oz can pineapple chunks in juice
  • ½ cup brown sugar
  • ½ cup rice vinegar
  • ¼ cup ketchup
  • 2 tablespoons soy sauce
  • 2 tablespoons cornstarch

Instructions

  • Add meatballs to slow cooker
  • Remove ribs and seeds from peppers, chop them into chunks, then add to slow cooker
  • Peel onion, cut into chunks, and add to slow cooker
  • Drain juice from pineapple and set aside
  • Add pineapple chunks to slow cooker
  • Whisk together reserved pineapple juice, brown sugar, vinegar, ketchup, and soy sauce
  • Mix cornstarch with 2 tablespoons of water until smooth, then whisk slurry into pineapple juice mixture
  • Pour mixture over meatballs in slow cooker
  • Cover and cook on high for 2-3 hours or low for 4-6 hours until fully heated through and sauce has thickened

Notes

  • Store leftovers in an airtight container in the fridge for up to 4 days, and skip freezing since the texture may change.
  • Reheat on the stovetop over low heat with a splash of broth if needed, or in the microwave in short intervals, stirring between each.
  • Frozen meatballs do not need to be thawed.
  • If using homemade meatballs, I recommend lightly browning first to help them hold together.
  • To thicken the sauce, whisk in a cornstarch slurry (1 tablespoon cornstarch + 1 tablespoon water) and cook on high for an additional 15 minutes.
