Equipment (7)

Panini press or grill pan with a heavy skillet for pressing
Rimmed baking sheet, 18×13-inch (46×33 cm), lined with parchment paper
Large mixing bowl
Medium saucepan or deep skillet (10-inch/25 cm) with lid
Instant-read thermometer
Serrated bread knife
Pastry brush

Steps

Before you start

Preheat the oven to 425°F (220°C) with a rack in the middle before you start mixing.
Use low-moisture mozzarella (sliced or block), not fresh mozzarella in water, which makes the sandwiches soggy.
Choose sturdy 6-inch Italian rolls with a crisp crust and soft interior; very soft hot dog-style buns will flatten and tear.
The meatballs can be baked and simmered in sauce in advance (see make ahead), so only assembly and pressing are left at serving time.

1
Mix the meatballsOven 425°F / 220°C
- Preheat the oven to 425°F (220°C) and line a rimmed baking sheet with parchment.
- In a large bowl, stir the panko and milk together and let sit 2 minutes while you prep the other ingredients.
- Add the egg, 1/4 cup Parmesan, garlic, parsley, oregano, salt, and pepper and stir to combine.
- Add the cold ground beef and mix gently with your hands for about 30 seconds, just until evenly combined.

Ready when: No streaks of unmixed panko or egg remain, and the mixture looks uniform but not pasty.
Tip: Overmixing makes meatballs dense and rubbery. Stop as soon as everything is evenly distributed.
2
Shape the meatballs
- Scoop about 2 tablespoons (roughly 35 g) of the mixture and roll it between damp palms into a smooth ball about 1¼ inches (3 cm) wide.
- Place on the lined baking sheet, spacing them about 1 inch (2.5 cm) apart.
- You should have 16 meatballs.
+ Show details− Hide details
Ready when: 16 evenly sized, smooth balls on the sheet.
Tip: Keep a small bowl of water nearby to dampen your hands so the mixture doesn't stick.
3
Bake the meatballsOven 425°F / 220°C
- Bake in the 425°F (220°C) oven for 13 to 15 minutes, until the meatballs are browned on top and firm to the touch.
- Check one by inserting an instant-read thermometer into the center.
+ Show details− Hide details
Ready when: Browned outside, no pink in the center, and 160°F (71°C) on an instant-read thermometer.
Tip: Baking is less messy than pan-frying and gives even browning, which adds flavor to the sauce.
4
Simmer in marinara
- While the meatballs bake, pour the marinara into a medium saucepan or deep 10-inch (25 cm) skillet and warm over medium-low heat until steaming.
- Transfer the baked meatballs to the sauce, spoon sauce over them, cover, and simmer gently for 10 minutes, turning once, so they absorb flavor and turn very tender.
- Turn off the heat and leave covered.
+ Show details− Hide details
Ready when: Sauce barely bubbles at the edges and the meatballs are hot throughout and feel tender when pierced with a fork.
Tip: Keep the simmer gentle; hard boiling can toughen the meatballs and spatter sauce.
5
Prep the rolls
- Turn the panini press on to medium-high (about 400°F/200°C).
- Split each roll lengthwise with a serrated knife, leaving one long edge attached.
- If the rolls are very doughy, pull out a little of the soft crumb from each side to make a shallow trough.
- Brush the outside of the top and bottom of each roll lightly with the olive oil, using about 1½ teaspoons per roll.
+ Show details− Hide details
Ready when: Rolls open like a book and the outsides are glossy with oil.
Tip: Don't over-hollow the rolls. The crust must stay thick enough to hold the filling.
6
Assemble the paninis
- Open each roll and lay 1 slice of mozzarella on the bottom half.
- Using a slotted spoon, lift 4 meatballs per sandwich from the sauce, letting excess drip off, and place on the cheese.
- Gently press each meatball with the back of a fork to flatten it slightly so it sits snugly.
- Spoon about 1 tablespoon of sauce over the meatballs, sprinkle with 1 tablespoon Parmesan, add 3 basil leaves if using, and top with a second slice of mozzarella.
- Close the roll firmly.
- Keep the remaining sauce warm for dipping.
+ Show details− Hide details
Ready when: Each sandwich closes without meatballs rolling out, with cheese both under and over the filling.
Tip: Too much sauce inside makes the bread soggy and sends cheese oozing out. Use only 1 tablespoon per sandwich and serve the rest on the side.
7
Press until golden
- Place 2 sandwiches on the preheated press (cook in two batches if your press is small).
- Close the lid gently and cook for 4 to 5 minutes, pressing lightly, until the bread is deeply golden with grill marks and the cheese is melted.
- If using a grill pan, cook over medium heat and press with a heavy skillet, flipping after 3 minutes, for 6 to 7 minutes total.
- Repeat with the remaining sandwiches.
+ Show details− Hide details
Ready when: Crust is crisp and golden, the sandwich feels firm when tapped, and melted cheese is just starting to peek from the edges.
Tip: Apply light pressure at first. Pressing hard squeezes out the sauce and flattens the meatballs.
8
Rest, slice, and serve
- Transfer the paninis to a cutting board and let rest for 5 minutes so the cheese sets slightly and the filling doesn't slide out.
- Cut each in half diagonally with a serrated knife using a gentle sawing motion.
- Serve right away with the warm leftover sauce for dipping.
+ Show details− Hide details
Ready when: Cheese is melted but no longer runny, and the sandwich holds together when cut.
Tip: Slice with a serrated knife, not a chef's knife, to avoid crushing the crisp crust.

Good to know

Tips

Use cold ground beef and handle it lightly for tender meatballs.
Drain meatballs with a slotted spoon and use only a little sauce inside; serve the rest for dipping to keep the bread crisp.
Flatten the meatballs slightly (or cut in half) when assembling so the sandwich presses evenly and doesn't squirt out.
No panini press? Cook in a heavy skillet over medium heat, pressing with a second heavy pan, and flip once.

Make ahead

"Bake the meatballs and simmer them in the marinara up to 3 days ahead. Cool, then refrigerate in the sauce in an airtight container. Reheat gently in a saucepan over medium-low heat until steaming hot (165°F/74°C) before assembling. Raw shaped meatballs can also be refrigerated on the baking sheet, covered, for up to 24 hours before baking."

Storage & reheating

"Pressed paninis are best eaten immediately. Wrapped tightly, leftovers keep in the fridge up to 2 days; reheat in a 350°F (175°C) oven for 10 to 12 minutes or until hot through. Do not store at room temperature for more than 2 hours. Meatballs in sauce keep in the fridge up to 4 days, or in the freezer up to 3 months; thaw overnight in the fridge and reheat gently on the stove until steaming. Assembled, unpressed paninis do not freeze well."

Substitutions

ground beef, 85% lean → Half ground beef and half ground pork, or ground turkey. Beef and pork gives a richer, more tender meatball. Turkey is leaner and can be drier, so don't skip the milk soak. Cook to 165°F (74°C) for turkey.
panko breadcrumbs → Fresh breadcrumbs or plain dried breadcrumbs. Use 1/3 cup (35 g) dried plain breadcrumbs, or 3/4 cup (40 g) fresh breadcrumbs.
low-moisture mozzarella → Provolone slices. Provolone gives a sharper flavor and melts well. Use 8 slices or about 8 oz (225 g).
Italian rolls, about 6 inches (15 cm) long → Ciabatta rolls or sturdy sourdough slices. Use 8 slices of sourdough (about 1/2 inch thick) for 4 sandwiches; reduce pressing time by about 1 minute.
