Step-by-Step Instructions

1. Prepare the Meat Mixture

In a large 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 overmixing, which can make the meat tough.

Divide the mixture into 8 equal portions and loosely roll them into balls.

2. Heat the Skillet

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

A cast-iron surface works especially well because it creates deep browning and crisp edges.

---

3. Smash the Meatballs

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

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

Cook for 3–4 minutes until a dark golden crust forms underneath.

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

Repeat with the remaining meatballs.

4. Warm the Marinara Sauce

While the meat cooks, heat the marinara sauce in a saucepan over medium-low heat until hot.

Once the smashed meatballs are cooked, spoon a little marinara sauce over each piece of meat.

---

5. Toast the Rolls

Preheat the broiler.

Mix the softened butter with garlic powder. Spread the mixture onto 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 prevent burning.

---

6. Assemble the Smashed Meatball Subs

Place two smashed meatball patties inside each toasted roll.

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

Return the sandwiches to the broiler for 1–2 minutes until the cheese melts and bubbles.

Finish with fresh basil or parsley and a sprinkle of Parmesan cheese.

Serve immediately while hot.

Expert Tips for the Best Smashed Meatball Subs

Use a Blend of Beef and Pork

Combining beef and pork creates richer flavor and better texture. Beef provides structure while pork adds moisture and tenderness.

Don’t Overwork the Meat

Mix only until combined. Overmixed meat becomes dense rather than juicy.

Smash Immediately

Press the meatballs shortly after placing them on the skillet while the meat is still cold. This helps create thin patties with crisp edges.

Choose the Right Bread

A sturdy hoagie roll holds up best against marinara sauce and melted cheese without becoming soggy.

Broil for Restaurant-Style Finish

A quick trip under the broiler gives the cheese a bubbly, golden finish and lightly crisps the bread.

Delicious Variations

Spicy Smashed Meatball Subs

Add crushed red pepper flakes or diced Calabrian chiles to the meat mixture for heat.

Chicken Meatball Subs

Replace the beef and pork with ground chicken or turkey for a lighter version.

Extra Cheesy Version

Layer provolone and mozzarella together for a richer, stretchier cheese pull.

Gluten-Free Option

Use gluten-free breadcrumbs and gluten-free sandwich rolls.

Low-Carb Version

Serve the smashed meatballs over roasted vegetables or inside lettuce wraps instead of bread.

Reheat the meatballs in a skillet over medium heat or in a 350°F oven until warmed through.

Common Mistakes to Avoid

Using Lean Meat

Very lean meat dries out quickly. An 80/20 beef blend creates the juiciest results.

Skipping the Toasted Bread

Toasted rolls prevent sogginess and add essential crunch.

Crowding the Pan

Cook in batches to maintain proper browning and crisp edges.

Adding Too Much Sauce

Too much marinara can overwhelm the sandwich and make the bread soggy.
