How to Make Italian Sub Sandwich Recipe
Step 1: Prepare Fresh Vegetables and Bread
Start by slicing the tomato and red onion thinly for even layering. Then, carefully slice open your hoagie rolls, making sure not to cut all the way through to hold the fillings snugly.
Step 2: Layer the Meats and Cheese
Begin by layering the salami and capicola evenly inside the hoagie rolls, followed by generous slices of provolone cheese. This gives your sandwich that deliciously rich foundation with a perfect Italian meat and cheese combo.
Step 3: Add the Fresh Veggies and Peppers
Next, pile on shredded romaine lettuce for crunch, followed by the juicy tomato slices, thin onion rings, and banana peppers if you’re using them. These fresh ingredients add vibrancy and a pop of tangy flavor.
Step 4: Whisk and Drizzle the Dressing
In a small bowl, whisk together the extra virgin olive oil and balsamic vinegar. Taste and adjust the balance if needed. Once ready, drizzle the dressing generously over the sandwich fillings to bring everything together with a delightful tang and smooth finish.
Step 5: Close, Press, and Serve
Gently close the hoagie roll, pressing down lightly to meld all those wonderful flavors and keep the layers compact for easy eating. Cut the sandwich in half if you like, making it ready to serve with your favorite sides.
How to Serve Italian Sub Sandwich Recipe

Garnishes
A sprinkle of fresh herbs like chopped parsley or basil can elevate your Italian Sub Sandwich Recipe with an extra bright, herbaceous touch. A few cracked black peppercorns or a pinch of sea salt on top also enhance the freshness of the vegetables and the sharpness of the meats.
Side Dishes
This sandwich pairs wonderfully with classic sides like kettle-cooked potato chips for crunch or a crisp garden salad tossed with a light vinaigrette to complement the rich flavors without overpowering them. Consider serving with pickles or marinated olives to keep that Italian vibe going strong.
Creative Ways to Present
For a fun twist, try slicing the sandwich into bite-sized sliders to serve as appetizers at a party, or wrap it tightly and slice into pinwheels for an impressive platter. You can also toast the hoagie bread lightly before assembling for a warm, slightly crispy variation that adds a new texture dimension.
Make Ahead and Storage
Storing Leftovers
If you have leftover Italian Sub Sandwich portions, wrap them tightly in plastic wrap or foil and store in the refrigerator. To keep the bread from getting soggy, store the dressing separately and add it when you’re ready to eat.
Freezing
This sandwich is best enjoyed fresh, but if you want to freeze it, assemble without lettuce, tomato, or dressing, then wrap tightly and freeze for up to one month. Thaw overnight in the fridge and add fresh veggies and dressing before serving for optimal texture and flavor.
Reheating
To enjoy your sandwich warm, unwrap and toast it in a preheated oven at 350°F (175°C) for about 5-7 minutes until the cheese slightly melts. Avoid microwaving directly with fresh veggies and dressing as they may become soggy or lose texture.
FAQs
Can I customize this Italian Sub Sandwich Recipe?
Absolutely! This recipe is very versatile. Feel free to switch up the meats, cheeses, or veggies to suit your preferences. Adding ingredients like roasted red peppers or different cheeses like mozzarella can give it your own twist.
What type of bread works best for this sandwich?
Hoagie rolls or Italian sandwich rolls are ideal as they are sturdy enough to hold all the fillings without falling apart, yet soft enough to bite into easily. A lightly toasted or fresh roll both work beautifully.
Is this sandwich suitable for meal prep?
Yes, but it’s best to keep wet ingredients like tomatoes, lettuce, and dressing separate until you’re ready to eat. This helps the sandwich stay fresh without getting soggy during storage.
Can I make this sandwich vegetarian?
Definitely. Substitute the meats with hearty grilled vegetables, marinated artichokes, or even slices of fresh mozzarella for a vegetarian-friendly version that still delivers on flavor and texture.
How long does the sandwich stay fresh after assembling?
For the best taste and texture, consume the sandwich within a few hours after assembling. If refrigerated, it’s best eaten within 24 hours, especially if it includes fresh veggies and dressing.
