How to Make Smashed Meatball Subs

1. Prepare the Meat Mixture

In a large mixing bowl, combine the ground beef, ground pork, breadcrumbs, Parmesan cheese, egg, garlic, parsley, salt, pepper, and Italian seasoning.

Mix gently with your hands until just combined. Avoid overworking the meat to keep the texture tender.

Divide the mixture into 8 equal portions and lightly shape into balls.

2. Heat the Skillet

Place a large cast-iron skillet or flat-top griddle over medium-high heat. Add olive oil and allow it to heat until shimmering.

A cast-iron skillet creates the best crust and helps the meat develop deep savory flavor.

---

3. Smash the Meatballs

Place the meatballs onto the hot skillet, leaving space between each one.

Using a heavy spatula or burger press, firmly smash each meatball into a thin patty about 1/2 inch thick.

Cook for 3–4 minutes until the underside develops a dark golden-brown crust.

Flip and cook another 2–3 minutes until fully cooked through and the internal temperature reaches 160°F.

Repeat with the remaining meat mixture.

4. Warm the Marinara Sauce

Heat the marinara sauce in a saucepan over medium-low heat until hot.

Spoon a small amount of sauce over the smashed meat patties during the final minute of cooking.

---

5. Toast the Rolls

Preheat the broiler.

Combine softened butter and garlic powder. Spread the mixture over the cut sides of the hoagie rolls.

Place the rolls on a baking sheet and broil for 1–2 minutes until lightly golden and crisp.

Watch carefully to avoid burning.

---

6. Assemble the Subs

Place two smashed meatball patties into each toasted roll.

Top with additional marinara sauce and two slices of mozzarella cheese.

Broil for another 1–2 minutes until the cheese is melted and bubbly.

Garnish with fresh basil or parsley and extra Parmesan cheese before serving.

Serve hot.

Expert Tips for Perfect Smashed Meatball Subs

Use Meat With Enough Fat

Ground beef with 20% fat creates juicy smashed meatballs with flavorful crispy edges.

Smash While Cold

Smashing the meat immediately after placing it on the skillet helps achieve a thin, crisp crust.

Toast the Bread

Toasted bread prevents sogginess and adds texture that balances the rich filling.

Don’t Overcrowd the Pan

Cook in batches if needed. Crowding traps steam and reduces browning.

Choose Quality Marinara

A balanced tomato sauce with garlic and herbs enhances the overall flavor of the sandwich.

Common Mistakes to Avoid

Using Extra-Lean Meat

Lean meat tends to dry out quickly and will not form the same crispy crust.

Overmixing the Meat

Overworked meat becomes dense and tough rather than tender.

Skipping the Toasted Rolls

Soft untoasted bread can become soggy from the marinara sauce.

Cooking Over Low Heat

High heat is essential for developing caramelization and crispy edges.
