Breadcrumbs (Best Option)
1:1 (1 cup breadcrumbs per 1 cup all-purpose flour)Breadcrumbs work well because they absorb moisture and fat, helping to bind the meat mixture similarly to flour. Their fibrous texture mimics the structural role of flour in meatballs.
For best results, use plain or lightly seasoned breadcrumbs and avoid overly coarse types to maintain a uniform texture. If using fresh breadcrumbs, slightly dry them before mixing.
Compared to flour, breadcrumbs can enhance the tenderness and juiciness of meatballs without making them dense or gummy.
