There are a few potential causes for your sausage balls to separate. It can be because there aren't enough binders, such as panko breadcrumbs or eggs, or the sausage meat isn't the right consistency. Another factor that might cause the balls to disintegrate is overmixing the ingredients. Additionally, some cooking techniques, such as baking at high temperatures, may impact the binding. You may strengthen the binding and stop the sausage balls from breaking apart by modifying the recipe, adding binders, and ensuring appropriate mixing and shape.
