Ingredients for Baked Italian Sub Sandwiches

Here’s what you’ll need to make 4 hearty sandwiches:

• 4 sandwich rolls (Keep the hinge intact—don’t slice all the way through)
• 1/2 lb deli ham
• 1/2 lb sliced salami
• 1/2 lb roast beef or cooked ground beef
• 1/4 lb sliced pepperoni (optional but highly recommended for extra flavor)
• 8 slices of provolone or mozzarella cheese
• 1/2 cup pickled banana peppers or roasted bell peppers
• 1/2 cup sautéed onions (optional, but adds depth)
• 1 tbsp Italian seasoning
• 2 tbsp melted butter

Kitchen Equipment You’ll Need

To make this recipe as easy and efficient as possible, gather the following tools:

• Baking sheet
• Parchment paper
• Sharp knife
• Basting brush
• Foil
• Small sauté pan (if using onions)
• Oven or toaster oven

Step-by-Step Instructions

1. Preheat Your Oven

Set your oven to 375°F (190°C). While it heats, line a baking sheet with parchment paper for easy cleanup.

2. Prep the Rolls

Carefully slice your sandwich rolls lengthwise, but don’t cut all the way through—leave them hinged so they hold everything together when baked.

3. Layer the Meats

Start filling each roll with an even portion of deli ham, salami, and roast beef (or ground beef). Add pepperoni if using—it boosts the flavor and adds a satisfying, slightly spicy kick.

4. Add Cheese and Veggies

Place two slices of cheese into each sandwich. Tuck in your banana peppers and onions here if using. They add texture, tang, and a little zing that cuts through the richness of the meat and cheese.

5. Assemble and Season

Place your loaded sandwiches onto the baking sheet. Brush the tops with melted butter and generously sprinkle Italian seasoning on each one.

6. Bake to Perfection

Cover the sandwiches loosely with foil and bake for 10–15 minutes, or until the cheese is melty and the meat is heated through. Then, remove the foil and bake uncovered for an additional 2–3 minutes to crisp up the tops.

7. Serve and Enjoy

Serve immediately while they’re hot and gooey. Pair with fries, a crisp side salad, or marinated olives for the full Italian deli experience.

Pro Tips and Swaps

➤ Meat Options

• Swap out any deli meat with your favorites. Turkey, pastrami, or even thinly sliced grilled chicken all work.
• Want it vegetarian? Try roasted eggplant, mushrooms, or plant-based deli slices.

➤ Cheese Varieties

• Mozzarella and provolone are classic, but Swiss, Havarti, or pepper jack are great for variety.
• For a sharper flavor, try aged provolone or a little shredded parmesan sprinkled on top before baking.

➤ Bread Choices

• Sub rolls work best, but you can use hoagie rolls, ciabatta, or even baguettes.
• Avoid overly soft rolls—they may get soggy during baking.

➤ Add-Ons

• Spread a thin layer of marinara or spicy mustard inside the bread before layering the meats.
• Add a few slices of tomato or shredded lettuce after baking for contrast.

How to Store and Reheat Leftovers

If you have leftovers (unlikely!), here’s how to keep them fresh:

• Storage: Wrap cooled sandwiches tightly in foil or place in an airtight container. Store in the fridge for up to 3 days.
• Reheating: For best results, reheat in a toaster oven or regular oven at 350°F for about 10 minutes. Avoid the microwave—it can make the bread chewy and soggy.

Pairing Suggestions

Sides

• Garlic parmesan fries
• Marinated olives
• Italian pasta salad
• Roasted vegetable skewers

Drinks

• A chilled Italian soda or sparkling water with lemon
• A crisp lager or amber ale
• Red wine: Chianti or Barbera

Frequently Asked Questions

Can I make these sandwiches ahead of time?

Yes! Assemble the sandwiches, wrap them in foil, and store them in the fridge. Bake when ready to eat—just add an extra 2–3 minutes to the baking time.

Can I freeze baked Italian subs?

You can, but results may vary. Wrap tightly in foil and freeze for up to one month. Reheat in a 375°F oven from frozen for about 20–25 minutes.

Are these sandwiches spicy?

Not by default, but the pepperoni and banana peppers add a mild heat. If you’re sensitive to spice, skip those or replace with mild roasted peppers.

Can I use shredded cheese instead of sliced?

Absolutely. Use about 1/3 cup per sandwich. Shredded cheese melts quickly and evenly.
