Notes
Brown the Meatballs First: For extra flavor, lightly brown the meatballs in a pan before adding them to the slow cooker.Use Fresh Breadcrumbs: Fresh breadcrumbs give a better texture and flavor compared to store-bought dry ones.Don’t Overcrowd the Slow Cooker: Give the meatballs some space in the slow cooker to cook evenly and get that perfect tender texture.
