👨🍳 Instructions
Preheat your oven to 375°F (190°C) and simmer the beef meatballs in a skillet with the mild marinara sauce for 10 minutes until hot.
Slice the sub rolls open lengthwise and place them on a baking sheet.
Spoon the warm meatballs and extra marinara sauce into each sub roll, arranging them neatly.
Top generously with shredded mozzarella cheese, brush roll edges with garlic butter, and bake for 6 to 8 minutes until the cheese is melted and bubbling.
⚠️ Common Mistakes
- ✕
Soggy bread: Drenching the sub rolls in too much watery sauce will make the bread mushy; use just enough to coat the meatballs.
- ✕
Burning edges: Watch closely during the final minutes of baking so the tips of the sub rolls don't char.
- ✕
Large meatballs: Oversized meatballs make the sandwich difficult to hold and bite for younger children.
🔄 Variations
Turkey meatball swap: Substitute turkey meatballs for the beef meatballs if preferred.
Gluten-free swap: Use gluten-free sub rolls for a gluten-free dinner option.
Parmesan finish: Sprinkle grated parmesan cheese over the melted mozzarella right before serving.
