Pour the Dr. Pepper into your slow cooker, followed by the BBQ sauce. Stir well until the two are fully combined.
Place the frozen meatballs into the slow cooker, ensuring they are evenly distributed. Use a spoon to gently coat each meatball with the sauce mixture.
If using frozen meatballs, set the slow cooker to HIGH and cook for 3 hours. If the meatballs are thawed, cook on LOW for 3 hours.
Before serving, confirm the internal temperature of the meatballs has reached 165°F to ensure they are fully heated. Serve hot as an appetizer or over rice for a hearty meal.
