Place all the sauce ingredients in your slow cooker. Stir well.
In a medium bowl, combine ground beef, breadcrumbs, egg, salt, pepper, basil, oregano and garlic powder. For best results use your hands to mix everything.
Take a small amount of mixture and roll it into a bite-size ball. Repeat until you have used up all the meat mixture.
In a skillet/frying pan, heat the oil and quickly brown the meatballs. Transfer them to the slow cooker and cook on high for 2 hours. About an hour into cooking, stir the meatballs so that they are all covered in the sauce. Check the internal temperature before turning off the slow cooker.
Best served warm!
Notes
If you don’t have basil, use oregano only (instead of 1 teaspoon, use 2 teaspoons) and vice versa.
Check the meatballs after 2 hours to see if they are cooked. Your thermometer should read at least 165°F/75°C.
The amount of hot sauce can be increased or decreased, depending on your taste. I’d say start with less and add at the very end if needed.
