The perfect meatball sandwich first needs perfect meatballs and great sauce. Once you have those two in place, the rest is a matter of construction and detail. Here’s how we like to build ours.
4 individual-sized Italian-style rolls
Extra-virgin olive oil, for drizzling
1 medium clove garlic, halved
1 recipe cooked Juicy and Tender Italian-American Meatballs in Red Sauce, warm
Pargmigiano-Reggiano, for grating
1 pound fresh or low-moisture mozzarella, sliced about 1/4 inch thick
Step 1Preheat oven to 350°F. Warm rolls in oven, 5 to 10 minutes. Slice off and discard ends of each roll. Cut rolls in half lengthwise.
Step 2Drizzle cut sides of top and bottom roll halves with olive oil and rub with clove of garlic until fragrant. Arrange bottom roll halves on a baking sheet, cut side up. Spoon a generous layer of tomato sauce onto each of the bottom halves.
Step 3Slice meatballs in half and arrange on sandwiches, overlapping as necessary for even coverage. Spoon more tomato sauce on top of meatball halves and grate Parmesan all over.
Step 4Lay sliced mozzarella on top of meatballs. Transfer baking sheet to oven and bake until mozzarella is fully melted, about 4 minutes; warm roll top halves in oven for last minute of cooking.
Step 5Close sandwiches and serve immediately.
