Step 1

Add the frozen meatballs to the slow cooker.

Step 2

Add the diced white onion and barbecue sauce. Stir.

Step 3

Cover and cook on high for 2.5 hours or on low for 4 hours. Stir occasionally so the meatballs won't burn on the edges.

Step 4

Serve as an appetizer with toothpicks or as dinner on top of mashed potatoes or rice. Or you can serve on slider or hoagie rolls.

Step 5

After the cooking time is up, set the slow cooker to the warm setting.

Step 6

The meatballs can be kept warm for up to 3 hours. Check on the meatballs occasionally and stir. Add a splash of water if sauce seems to be dry.
