Instructions

1. Preheat the oven to 200°C (400°F). Line a baking sheet with parchment paper.

Zusatztipps für die Zubereitung

For the juiciest meatballs, avoid overmixing the beef mixture to keep them tender. Baking the meatballs instead of frying reduces grease while ensuring even cooking. Toasting the rolls before assembly adds a wonderful texture contrast to the tender meat and melty cheese.

Varianten und Anpassungen

For extra flavor, try mixing half ground pork with the beef in your meatballs. You can also add sautéed bell peppers or sliced olives to the marinara sauce for a creative twist. For gluten-free options, substitute breadcrumbs and rolls accordingly without compromising taste.
