These slow cooker party meatballs simmered in a sweet grape jelly glaze are an effortless, crowd-pleasing appetizer perfect for gatherings and potlucks. The sweet and tangy sauce pairs beautifully with tender meatballs for a deliciously addictive flavor.
For thicker sauce, remove lid in the last 30 minutes and cook on high to reduce glaze. Avoid over-stirring to keep meatballs intact. Let meatballs rest in sauce for 15 minutes after cooking for best flavor. Can be made ahead and refrigerated overnight before cooking. For spicy variation, add hot sauce, cayenne pepper, or chopped jalapeños. Can bake in oven at 350°F for 45 minutes if no slow cooker is available.
