These meatball subs are the kind of gloriously messy sandwich that requires a stack of napkins and zero apologies. Toasting the rolls keeps them from getting soggy while the meatballs and sauce do their saucy thing.

Why This Recipe Works

Toasting the hoagie rolls with a brush of garlic butter creates a crispy barrier that stands up to the sauce. Broiling the assembled subs melts the cheese and warms everything through at once.

Ingredients

  • 20 frozen or homemade meatballs
  • 1 jar (24 oz) marinara sauce
  • 6 hoagie rolls, split
  • 2 cups shredded mozzarella cheese
  • 2 tbsp butter, softened
  • 1/2 tsp garlic powder

Instructions

  1. 1

    Simmer meatballs in marinara sauce in a covered saucepan over medium heat for 20 minutes until heated through.

  2. 2

    Mix softened butter with garlic powder. Spread inside each hoagie roll and toast under the broiler 1-2 minutes.

  3. 3

    Fill each toasted roll with 3-4 meatballs. Spoon extra sauce over the top.

  4. 4

    Top with shredded mozzarella and return to the broiler for 2-3 minutes until cheese is melted and bubbly.

  5. 5

    Serve immediately with extra sauce on the side for dipping.

Olive Oil

Helpful Pantry Staple

Why the olive oil matters

On recipes like this, olive oil is not just a background fat. A better bottle gives you cleaner flavor and a better finish.

This is one of the few pantry upgrades that keeps paying off every time you cook in this lane.

  • Useful in dressings, sauces, and finishing
  • Improves flavor without changing the recipe structure

A good bottle of olive oil is one of the safest pantry upgrades for Mediterranean and Italian cooking.

Tips & Storage

Pro Tips

  • Brush the inside of the rolls with garlic butter before toasting to create a flavor-packed, sauce-resistant barrier.

  • Use a fork and knife or wrap the bottom in foil for less messy eating.

Storage

Refrigerate assembled subs up to 2 days, though they are best fresh. Store meatballs in sauce up to 5 days.

Reheating

Reheat meatballs in sauce on the stovetop, then assemble fresh subs.
