Crockpot Mississippi meatballs make the best little appetizer or side dish. The flavorful pepperoncini mixed with the au jus and ranch seasoning packets with delectable butter makes the most amazing sauce. It's perfectly soaked up by the tender meatballs.
Place the frozen meatballs in the bottom of a crockpot. Sprinkle the au jus gravy mix and the ranch mix over the meatballs.
Pour the pepperoncini peppers, their juice, and the water over the meatballs and seasonings.
Place the diced butter over the contents of the crockpot. Cover and cook on LOW for 3-4 hours. Stir the meatballs every 30 minutes or so to keep them from burning.
When the meatballs are heated through, serve them on their own or over potatoes.
