  • Not seasoning enough: A lack of seasoning can lead to bland meatballs. Be sure to use salt, pepper, and garlic powder generously.
  • Overcrowding the crockpot: If you pack too many meatballs into the crockpot, they may not cook evenly. Always leave space between them for better heat circulation.
  • Ignoring the cooking time: Cooking for too little or too long can lead to dry or mushy meatballs. Stick to the recommended cooking times for best results.
  • Forgetting to cover while cooking: Leaving the lid off can dry out your meatballs. Always keep it covered during cooking for moist results.
