Step-by-Step: How to Make Chicken Parmesan Meatball Subs
You can break this recipe down into three parts: meatballs, assembly, and baking. Let’s walk through it.
🔹 Step 1: Make the Chicken Meatballs
Preheat your oven to 400°F (200°C). Line a baking sheet with parchment or foil.
In a large mixing bowl, combine:
- 1 lb ground chicken
- 1 egg
- ½ cup breadcrumbs
- ¼ cup grated Parmesan
- 2 cloves garlic, minced
- 1 tsp Italian seasoning
- 1 tbsp chopped parsley
- Salt and pepper to taste
Mix gently with your hands or a spoon—don’t overmix or the meatballs will be tough.
Form into small balls, about 1 to 1.5 inches wide. You should get 18–20 meatballs.
Place them on the baking sheet and bake for 18–20 minutes, or until fully cooked and lightly golden.
🔹 Step 2: Warm the Sauce and Toast the Bread
While the meatballs are baking, warm 2 cups of marinara sauce in a saucepan over low heat.
Cut the hoagie rolls lengthwise (without slicing all the way through) and lightly toast them under the broiler or in a hot skillet for 1–2 minutes.
Pro tip: Brush the inside of the rolls with olive oil or melted butter and a sprinkle of garlic powder before toasting. Game-changer.
🔹 Step 3: Simmer Meatballs in Sauce
Once the meatballs are done, transfer them to the saucepan of warm marinara and let them simmer for 5–10 minutes. This helps them absorb flavor and stay juicy.
🔹 Step 4: Assemble the Subs
Here’s where it gets delicious.
- Line each toasted roll with a few spoonfuls of marinara sauce
- Add 3–4 meatballs per sub (depending on size)
- Spoon a little extra sauce over the top
- Sprinkle generously with shredded mozzarella
- Add a touch of Parmesan for extra flavor
🔹 Step 5: Melt the Cheese
Place the assembled subs on a baking sheet and pop them under the broiler for 2–3 minutes—just until the cheese is bubbly and browned in spots.
Keep an eye on them! They can go from golden to burned quickly under the broiler.
Sauce Options & Custom Toppings
Not a marinara fan? No problem! Try these creative sauces or toppings:
| Swap or Addition | Flavor Boost |
|---|---|
| Spicy arrabbiata sauce | Kicks it up a notch |
| Pesto drizzle | Adds herby richness |
| Sliced banana peppers | Tangy and bright |
| Caramelized onions | Sweet and savory contrast |
| Roasted red peppers | Color and smokiness |
| Fresh basil leaves | Bright, aromatic garnish |
Make it your own!
Serving Ideas & Sides
These subs are hearty on their own, but pairing them with a little something on the side takes your meal to the next level.
| Side Dish | Why It Works |
|---|---|
| Garlic Parmesan fries | Crispy and indulgent |
| Caesar salad | Crunchy and fresh balance |
| Roasted broccoli | Lightens up the plate |
| Chips + pickle spear | Classic sub shop vibe |
| Iced tea or lemonade | Refreshing and not too sweet |
Bonus: They pair really well with game day beer, too.
Make-Ahead & Storage Tips
Want to prep ahead? These subs are freezer- and fridge-friendly.
✅ To Store:
- Store meatballs and sauce separately in the fridge for up to 4 days
- Assemble sandwiches just before eating to avoid soggy bread
✅ To Freeze:
- Freeze cooked meatballs (without sauce) in a sealed bag or container for up to 2 months
- Reheat directly in marinara sauce on the stove
Turn It Into a Crowd-Pleaser
Feeding a group? Make mini meatballs and assemble on slider buns. Serve them party-style with toothpicks and a tray of dipping sauces.
These also work great as part of a buffet table—let everyone build their own sub with meatballs, sauce, cheese, and toppings. No complaints, guaranteed.
Healthier Swaps (If You Must!)
Trying to keep things a bit lighter? Here are a few easy modifications:
- Use whole wheat buns
- Try low-moisture part-skim mozzarella
- Use ground turkey or chicken breast
- Bake or air-fry meatballs instead of pan-frying
- Skip cheese (but… why would you?)
They’re still full of flavor, just with fewer indulgences.
Tips for Success
| Tip | Why It Matters |
|---|---|
| Don’t overmix the meat | Keeps meatballs tender and juicy |
| Toast the bread | Prevents soggy bottoms and adds texture |
| Use enough sauce | Moisture + flavor = winning combo |
| Don’t crowd the broiler | Melt cheese evenly and avoid burned spots |
| Serve immediately | Best texture when hot and fresh |
