Turkey Meatball Subs Mozzarella

I was standing in my kitchen on a Sunday afternoon, staring at a pound of ground turkey and wondering how to turn it into something my kids would actually get excited about. The marinara was already simmering on the stove, filling the air with garlic and basil, when I remembered the meatball subs from the sandwich shop near my old apartment. I figured I could make them lighter with turkey, and that afternoon turned into one of those rare wins where everyone asked for seconds.

The first time I made these for a small gathering, I watched people pull the subs apart and let the cheese stretch between halves, tomato sauce dripping just a little onto their plates. Someone said it tasted like the kind of sandwich you order without looking at the menu, the kind you just know will be good. That stuck with me because its exactly what I was going for, something familiar and satisfying without any fuss.

Ingredients

• Ground turkey: I use a mix thats about 93% lean so the meatballs stay moist but not greasy, and I learned the hard way not to overmix or theyll turn out dense.
• Breadcrumbs: These keep the meatballs from falling apart and add a little tenderness, and I always use plain or Italian-style depending on what I have around.
• Parmesan cheese: Grated finely, it adds a salty depth that makes the meatballs taste richer than they actually are.
• Egg: This binds everything together, and one large egg is just enough for a pound of turkey without making the mixture too wet.
• Garlic: I mince it fresh because the flavor is sharper and more present, especially when it bakes into the meatballs.
• Fresh parsley: It brightens the flavor, though dried works fine if youre in a pinch.
• Oregano: A little goes a long way, and it ties the meatballs to the marinara beautifully.
• Marinara sauce: I use a jar most of the time, but Ive also made it from scratch when I had extra tomatoes, and both work perfectly.
• Olive oil: Just enough to sauté the onion and garlic so the sauce base tastes fuller and a little sweet.
• Onion: I dice it small so it melts into the sauce and adds sweetness without being chunky.
• Red pepper flakes: Optional, but I like a tiny bit of heat in the background.
• Sub rolls: I toast them with a little butter so they hold up to the sauce and dont turn soggy halfway through eating.
• Mozzarella cheese: Shredded melts faster and more evenly, and I always add more than I think I need because its never enough.
• Butter: Softened and spread on the rolls before toasting, it makes them golden and crisp on the edges.

Instructions

Preheat and prep:

Set your oven to 400°F and line a baking sheet with parchment so the meatballs dont stick. This also makes cleanup easier, which I appreciate on busy nights.

Mix the meatballs:

Combine the turkey, breadcrumbs, Parmesan, egg, garlic, parsley, oregano, salt, and pepper in a large bowl, using your hands to mix gently until just combined. Overmixing makes them tough, so stop as soon as everything looks evenly distributed.

Shape and bake:

Roll the mixture into 16 meatballs, each about an inch and a half across, and arrange them on the baking sheet. Bake for 15 to 18 minutes until theyre cooked through and starting to brown on the outside.

Start the sauce:

While the meatballs bake, heat olive oil in a saucepan over medium heat and sauté the onion until its soft and translucent, then add the garlic and cook for another minute. The smell alone will make you hungry.

Simmer the marinara:

Stir in the marinara, basil, and red pepper flakes if youre using them, then turn the heat to low and let it simmer for about 10 minutes. This gives the flavors time to blend and the sauce thickens just a little.

Combine meatballs and sauce:

Add the baked meatballs to the saucepan and let them simmer together for another 5 minutes so they soak up some of the marinara.

Toast the rolls:

Split the sub rolls, spread softened butter on the cut sides, and toast them under the broiler or in a skillet until theyre golden and crisp.

Assemble the subs:

Place 4 meatballs and a generous spoonful of sauce into each roll, then top with shredded mozzarella. I like to pile it on because melted cheese is the whole point.

Melt the cheese:

Put the assembled subs under the broiler for 2 to 3 minutes, watching closely so the cheese gets bubbly and golden but doesnt burn.

Garnish and serve:

Sprinkle fresh basil or parsley on top if you have it, then serve the subs hot while the cheese is still gooey.

One evening, my neighbor came over while I was pulling these out of the oven, and she ended up staying for dinner without either of us planning it. We sat at the kitchen table with napkins piled high, laughing about how impossible it is to eat a meatball sub gracefully. That kind of meal, the kind that turns into an impromptu gathering, is exactly what this recipe has become for me.

What to Serve Alongside

I usually put out a simple green salad with a lemony vinaigrette to cut through the richness of the subs, or I roast some vegetables if I have extra time. Crispy fries or sweet potato wedges are always a hit with kids, and sometimes I just serve pickles and call it done because honestly, the subs are filling enough on their own.

How to Store and Reheat

Leftover meatballs and sauce keep well in an airtight container in the fridge for up to three days, and I reheat them gently on the stove so they dont dry out. I store the rolls separately and toast them fresh when Im ready to eat, because reheating an assembled sub never turns out quite right. If you freeze the meatballs in sauce, they hold up beautifully for up to two months, and you can thaw and reheat them whenever you need a quick dinner.

Ways to Make It Your Own

Ive swapped the turkey for ground chicken when thats what I had on hand, and Ive also used ground beef for a richer, more traditional version. Sometimes I sauté sliced bell peppers or mushrooms and tuck them into the subs with the meatballs, which adds another layer of flavor and makes them feel a little more substantial.

• Try adding a handful of fresh spinach to the meatball mixture for extra nutrition and a pop of color.
• Use provolone instead of mozzarella if you want a sharper, slightly smokier cheese flavor.
• For a gluten-free version, swap in gluten-free breadcrumbs and rolls, and double-check your marinara label.

These subs have become one of those recipes I make without thinking too hard about it, the kind that feels like a small celebration even on an ordinary Tuesday. I hope they bring the same easy comfort to your table.
