Turkey Meatball Subs

These turkey meatball subs are the answer to every weeknight dinner dilemma you've ever had. They're lighter than traditional beef meatballs but still incredibly satisfying, packed with Italian herbs and nestled in toasted sub rolls with melted mozzarella. This is the one I make every single time I need to feed a crowd without spending hours in the kitchen — game days, casual Friday nights, even meal prep Sundays. The meatballs stay tender, the marinara gets all bubbly and cheese-melted, and everyone goes back for seconds. You're about to have a new go-to recipe that feels special but comes together faster than takeout.

Ingredients

Here's everything you need to make tender, flavorful turkey meatball subs that'll become a weekly staple.

For the Turkey Meatballs:

• 1 pound (450g) ground turkey (93% lean works best)
• ½ cup (50g) Italian-style breadcrumbs
• ¼ cup (25g) grated Parmesan cheese
• 1 large egg, lightly beaten
• 3 cloves garlic, minced
• 2 tablespoons fresh parsley, finely chopped
• 1 teaspoon dried Italian seasoning
• ½ teaspoon salt
• ¼ teaspoon black pepper
• ¼ teaspoon red pepper flakes (optional, for a little kick)

For the Subs:

• 4 sub rolls or hoagie buns
• 2 cups (480ml) marinara sauce (store-bought or homemade)
• 1½ cups (170g) shredded mozzarella cheese
• 2 tablespoons olive oil
• Fresh basil leaves for garnish (optional)

A quick note on the ground turkey: choose 93% lean rather than 99% lean — you need a little fat to keep the meatballs moist and tender. If you can't find Italian-style breadcrumbs, use plain breadcrumbs and add an extra ½ teaspoon of Italian seasoning.

How to Make Turkey Meatball Subs

Follow these simple steps and you'll have restaurant-quality subs on your table in under 40 minutes.

1. Preheat your oven. Set it to 400°F (200°C) and line a large baking sheet with parchment paper or lightly grease it with cooking spray.
2. Mix the meatball ingredients. In a large bowl, combine the ground turkey, breadcrumbs, Parmesan, egg, garlic, parsley, Italian seasoning, salt, pepper, and red pepper flakes if using. Use your hands to mix gently until just combined — don't overmix or the meatballs will be tough.
3. Form the meatballs. Using a small cookie scoop or your hands, roll the mixture into 16 meatballs about 1½ inches in diameter. Place them on your prepared baking sheet with a little space between each one.
4. Bake the meatballs. Slide the baking sheet into the oven and bake for 18-20 minutes until the meatballs are cooked through and lightly golden on top. They should reach an internal temperature of 165°F (74°C) when you check with a meat thermometer.
5. Warm the marinara. While the meatballs bake, heat your marinara sauce in a medium saucepan over low heat, stirring occasionally, until it's hot and bubbling gently.
6. Toast the sub rolls. Slice the rolls open lengthwise but don't cut all the way through. Brush the insides lightly with olive oil and place them cut-side up on a baking sheet. Toast in the oven for 3-4 minutes during the last few minutes of meatball baking time until they're golden and crispy.
7. Assemble the subs. Place 4 meatballs in each toasted roll. Spoon generous amounts of warm marinara sauce over the meatballs — don't be shy here.
8. Add the cheese. Sprinkle shredded mozzarella generously over each sub, making sure to cover the meatballs completely.
9. Melt the cheese. Return the assembled subs to the oven on the baking sheet and broil on high for 2-3 minutes until the cheese is melted, bubbly, and starting to get golden spots. Watch them closely so they don't burn.
10. Garnish and serve. Pull them from the oven, top with torn fresh basil if you have it, and serve immediately while the cheese is still gooey and perfect.

Recipe Variations

What to Serve With Turkey Meatball Subs

These subs are hearty enough to stand on their own, but a few simple sides make the meal complete.

• Classic Caesar salad with crunchy romaine, shaved Parmesan, and plenty of croutons — the crisp, tangy greens balance the richness of the melted cheese perfectly
• Oven-baked sweet potato fries seasoned with a little smoked paprika and sea salt for a slightly healthier take on fries that everyone still loves
• Simple tomato soup for dunking — especially amazing on a chilly evening when you want maximum comfort food vibes
• Crispy roasted broccoli or green beans tossed with garlic and lemon to add something green and fresh to the plate

Storage & Make-Ahead Tips

These turkey meatball subs are perfect for meal prep and they freeze beautifully.

• Refrigerator: Store cooked meatballs in an airtight container with marinara sauce for up to 4 days. Reheat gently on the stovetop or in the microwave, then assemble fresh subs.
• Freezer: Freeze the cooked meatballs on a baking sheet until solid, then transfer to a freezer bag for up to 3 months. Thaw overnight in the fridge and reheat in marinara sauce before assembling. You can also freeze fully assembled (but untoasted) subs wrapped tightly in foil for up to 2 months.
• Make-ahead: Form the raw meatballs up to 24 hours ahead and keep them covered in the fridge until you're ready to bake. You can also make the meatballs and marinara sauce a day or two in advance and just assemble and broil when you're ready to eat.
• Reheating assembled subs: If you have leftover assembled subs, wrap them in foil and reheat in a 350°F (175°C) oven for about 12-15 minutes until warmed through. The foil keeps them from drying out.

Common Mistakes to Avoid

Frequently Asked Questions

Can I use ground chicken instead of turkey?

Absolutely. Ground chicken works exactly the same way as ground turkey in this recipe. Just make sure it's not extra-lean and follow all the same mixing and baking instructions. The flavor and texture will be nearly identical.

How do I keep turkey meatballs from falling apart?

The egg and breadcrumbs act as binders that hold everything together. Make sure you're using the full ½ cup of breadcrumbs and one whole egg, and mix just until combined — overmixing actually makes them more likely to crumble. Let them bake undisturbed for the full time so they can firm up properly.

Can I make these meatballs in a slow cooker?

Yes. Form and bake the meatballs as directed, then transfer them to your slow cooker with the marinara sauce. Cook on low for 2-3 hours to keep them warm for a party, or cook raw meatballs directly in the sauce on low for 4-5 hours. They won't have the same golden exterior, but they'll be tender and delicious.

What's the best store-bought marinara for this recipe?

Rao's Homemade is consistently the best if you want something that tastes homemade. Other great options include Classico, Victoria, or any marinara labeled "rustic" or "home-style." Avoid anything with added sugar as the first few ingredients — you want a sauce where tomatoes are the star.

Can I air fry the meatballs instead of baking them?

You can. Preheat your air fryer to 375°F (190°C) and cook the meatballs in a single layer for 10-12 minutes, shaking the basket halfway through, until they're golden and reach 165°F (74°C) internally. They'll have a slightly crispier exterior this way.
