This meatball sub garlic bread pasta bake combines two beloved Italian-American classics into one hearty, crowd-pleasing dinner. The base is al dente penne tossed with marinara and juicy beef meatballs, then topped with shredded mozzarella and garlic-butter sourdough cubes.

Baking at 400°F (200°C) for 20 minutes melts the cheese into a gooey blanket while the bread cubes turn golden and crunchy, mimicking the crispy edges of garlic bread. The result is a dish that tastes like a meatball sub and garlic bread all in one forkful. It's an easy, one-pan meal that's perfect for family dinners, game day, or any night you crave serious comfort food.

Ingredients

Why this recipe works

The method of tossing the penne with marinara before baking ensures every piece of pasta is coated in flavor, while the meatballs stay moist because they are nestled into the sauce rather than sitting on top.

The sauce also helps the pasta absorb extra flavor as it bakes, making each bite rich and satisfying. The final bake at high heat allows the cheese to melt and bubble without drying out the pasta, since the sauce provides enough moisture.

The garlic-butter sourdough cubes are the genius twist. Tossing the bread cubes in melted garlic-parsley butter and scattering them over the cheese creates a crunchy, golden topping that mimics garlic bread.

As they bake, the cubes crisp up while the cheese melts underneath, providing a delightful textural contrast. This technique ensures every serving includes a crispy, garlicky crouton-like bite, making the dish feel like a complete meal with built-in garlic bread.

Notes and substitutions

Use a good-quality marinara sauce or homemade if you have it. The sauce is the backbone of the dish, so choose one with rich tomato flavor and Italian herbs. For the meatballs, you can use homemade or store-bought; ensure they are fully cooked through when the bake reaches 160°F (71°C) internally. If using raw meatballs, brown them first to build flavor and help them hold together during baking.

Sourdough bread works beautifully here, but any crusty bread like Italian or French will do. Day-old bread is ideal because it crisps up better. The garlic-parsley butter can be made by mixing softened butter with minced garlic and chopped parsley, or you can use a high-quality garlic butter spread. If you don't have sourdough, regular sandwich bread can be cubed and toasted, but sourdough adds a superior crunch.

• penne pasta: Use any short pasta like rigatoni, ziti, or fusilli; adjust cooking time to package directions.
• marinara sauce: Use your favorite pasta sauce or crushed tomatoes with Italian seasoning.
• garlic-herb beef meatballs: Use turkey or chicken meatballs (ensure they reach 165°F internally) or store-bought frozen meatballs that are fully cooked.
• sourdough bread: Substitute with any crusty bread like Italian or French bread; day-old bread works best.
