2. Create meatball mixture by gently folding ground beef with softened breadcrumbs, incorporating herbs, seasonings, minced aromatics, cheese, and whisked egg. Blend carefully to maintain meat’s tender texture.
3. Shape uniform meatballs using two-tablespoon portions. Chill the formed meatballs for 15 minutes to help maintain structural integrity during cooking.
