Easy Preparation for a Crowd

One of the best aspects of this recipe is its simplicity. The meatballs come together in just minutes, requiring minimal effort to create a deliciously satisfying dish. By preparing a large batch, you can feed a crowd without spending hours in the kitchen. Simply bake the meatballs, assemble the subs, and pop them in the oven to achieve that perfect melt-in-your-mouth texture.

These Meatball Sub Bombs are not only quick to prepare but also perfect for sharing. The fun presentation encourages everyone to dig in, making it an ideal dish for gatherings. Plus, the leftovers (if there are any!) can be easily reheated for a tasty lunch the next day.

Cooking Tips for Success

To ensure your Meatball Sub Bombs turn out just right, consider using high-quality ingredients. Fresh herbs and good-quality ground beef can elevate the flavor significantly. Additionally, don’t skip on the cheese! A generous amount of mozzarella will create that irresistible cheesy pull that everyone loves.

Another tip is to let the meatballs rest for a few minutes after baking. This allows the juices to redistribute, making them even juicier and more flavorful. When assembling your subs, feel free to add extra toppings like sliced jalapeños, grilled onions, or even a sprinkle of crushed red pepper for a little kick.

Ingredients

For the Meatballs

  • 1 pound ground beef
  • 1/2 cup breadcrumbs
  • 1/4 cup grated Parmesan cheese
  • 1/4 cup chopped parsley
  • 1 egg
  • 2 cloves garlic, minced
  • 1 teaspoon salt
  • 1 teaspoon pepper
  • 1/2 teaspoon Italian seasoning

For Assembly

  • 1 cup marinara sauce
  • 1 cup shredded mozzarella cheese
  • 4 sub rolls
  • Olive oil for brushing

Make sure to preheat your oven before assembling your Meatball Sub Bombs!

Instructions

Prepare the Meatballs

In a large mixing bowl, combine ground beef, breadcrumbs, Parmesan cheese, parsley, egg, garlic, salt, pepper, and Italian seasoning. Mix until well combined and form into small meatballs.

Cook the Meatballs

Preheat your oven to 375°F (190°C). Place the meatballs on a baking sheet and bake for 20 minutes or until cooked through.

Assemble the Bombs

Slice the sub rolls lengthwise, leaving one side intact. Place a layer of marinara sauce inside each roll, followed by meatballs and a generous amount of mozzarella cheese.

Bake

Brush the outside of the rolls with olive oil, then place them in the oven for an additional 10 minutes until the cheese is melted and the rolls are golden.

Let the Meatball Sub Bombs cool for a few minutes before serving.

Serving Suggestions

These Meatball Sub Bombs are perfect on their own, but you can elevate the meal by adding a side of crispy fries or a fresh salad. The contrast of textures will enhance the overall dining experience. For a more Italian twist, consider serving them with a side of garlic bread to soak up any extra marinara sauce.

If you want to impress your guests, consider pairing these subs with a selection of dipping sauces. A creamy ranch or zesty marinara can add an extra layer of flavor and fun to the meal, allowing everyone to customize their bites.

Storage and Reheating Tips

If you find yourself with leftovers, storing them properly is key to maintaining their deliciousness. Allow the Meatball Sub Bombs to cool completely before placing them in an airtight container. They can be stored in the refrigerator for up to three days or frozen for up to three months.

When it comes to reheating, the oven is your best bet for keeping that crispy roll. Preheat your oven to 350°F (175°C), wrap the subs in foil to prevent drying out, and heat for about 15-20 minutes. This will help retain the texture and flavor of your Meatball Sub Bombs, ensuring they are just as delightful the second time around.
