Step‑by‑Step Instructions for Baked Italian Sub Sandwich
Step 1: Preheat Your Oven
Start by preheating your oven to 375°F (190°C). This temperature ensures that the Baked Italian Sub Sandwich will bake evenly, allowing all the flavors to meld beautifully. While the oven heats up, you can prepare your ingredients, so everything is ready to go when the oven reaches the desired temperature.
Step 2: Prepare the Bread
Slice the baguette or Italian sub roll in half lengthwise and lay the pieces cut-side up on a baking sheet. Make sure you’ve placed them so they’re stable and won’t tip over. This is where your hearty Baked Italian Sub Sandwich begins to take shape, ready to hold all those delicious fillings.
Step 3: Add Olive Oil
Lightly brush the inside of the bread with olive oil. This step not only aids in moisture retention but also enhances the flavor of your Baked Italian Sub Sandwich. The oil will give the bread a lovely golden hue as it bakes, creating that appealing crispy crust you crave.
Step 4: Layer the Meats
Evenly layer salami, ham, and pepperoni on the bottom half of the bread. Make sure to cover the surface completely for optimal flavor in every bite. As you build your Baked Italian Sub Sandwich, you’ll create a savory base that will complement the other layers perfectly.
Step 5: Add Cheese
Next, generously place slices of provolone cheese over the meats, ensuring you cover them thoroughly. The cheese will melt beautifully during baking, adding a creamy richness to your sandwich. This step is essential for achieving that gooey, satisfying texture in your Baked Italian Sub Sandwich.
Step 6: Top with Fresh Veggies
Now it’s time to add the fun crunch! Add shredded lettuce, tomato slices, red onion, and banana peppers on top of the cheese. Each ingredient contributes a fresh burst of flavor and texture, enhancing the overall experience of your Baked Italian Sub Sandwich. Don’t be shy—layer them on!
Step 7: Season It Up
Sprinkle Italian seasoning, salt, and pepper over the vegetable layers. Seasoning is key to bringing all the flavors together. As you season your Baked Italian Sub Sandwich, take care to distribute everything evenly to ensure each bite is just as delicious as the last.
Step 8: Assemble the Sandwich
Carefully close the sandwich with the top half of the bread. Once it’s closed, wrap the entire sandwich tightly in aluminum foil. This packaging will keep the moisture in during baking, helping the Baked Italian Sub Sandwich stay juicy and flavorful while the outside crisps up.
Step 9: Bake to Perfection
Place the wrapped sandwich in the preheated oven and bake for 15–20 minutes. You’ll know it’s ready when the cheese is thoroughly melted and the bread turns slightly crispy. Keep an eye on it towards the end of the baking to avoid overcooking.
Step 10: Slice and Serve
Once baked, carefully unwrap the sandwich. Use a serrated knife to slice through, creating perfect portions for serving. The layers will be invitingly gooey and warm, ready to be enjoyed as your Baked Italian Sub Sandwich steals the show at the table!

Baked Italian Sub Sandwich Recipe FAQs
What type of bread is best for the Baked Italian Sub Sandwich?

How should I store leftovers of my Baked Italian Sub Sandwich?
Store any leftovers in an airtight container in the fridge for up to 3 days. This helps maintain freshness and prevents the flavors from fading. When you’re ready to enjoy it again, I recommend reheating in the oven to achieve that delicious crispy texture.

Why is my sandwich soggy after baking?
To avoid a soggy sandwich, make sure to tightly wrap it in foil before baking to trap moisture while still allowing steam to circulate. If the bread is too soft before baking, consider toasting it lightly or using a firmer baguette. Also, layer meats and toppings evenly to prevent any heavy ingredients from making the bread soggy.
Can I make the Baked Italian Sub Sandwich vegetarian?
Very! You can easily customize this recipe to be vegetarian by omitting the meats and adding more hearty vegetables like roasted red peppers, olives, or mushrooms. You could also add an avocado layer for creaminess. Just be sure to adjust the seasoning to suit the added ingredients!
