Introduction

This Baked Italian Sub Sandwich is a delicious, melty twist on a classic deli favorite. Loaded with layers of meats, cheese, and tangy toppings, it’s baked to perfection for a warm, crave-worthy meal.

The image shows three thick sandwich slices arranged in a row on a wooden board atop a white marbled surface. Each sandwich has a golden-brown toasted crust with visible crunch and soft white interior bread. The first visible sandwich slice is layered with thin, folded layers of pink roast meat, topped by melted white cheese that slightly drips over the meat, sprinkled with green dried herbs. On top of each sandwich, there is a small sprig of green herbs for garnish. In the background, out of focus, is a small dark bowl filled with green olives. photo taken with an iphone --ar 4:5 --v 7

Ingredients

4 sub rolls or hoagie buns
¼ lb salami

¼ lb ham
¼ lb pepperoni or capicola

¼ lb roast beef (optional for a meatier sub)
8 slices provolone or mozzarella cheese

½ cup banana peppers or pepperoncini (sliced)
¼ cup red onion (thinly sliced)
½ cup Italian dressing

2 tablespoons butter (melted)
1 tablespoon Italian seasoning
½ teaspoon garlic powder

Instructions

Step 1: Slice your sub rolls in half lengthwise, keeping them hinged so they cradle the fillings. Lightly toast the inside surfaces if you prefer a crunchier texture.
Step 2: Layer the meats evenly inside the rolls: start with ham, then salami, pepperoni, and roast beef if using. Place slices of cheese between the meat layers, then add banana peppers and thinly sliced red onion on top.
Step 3: In a small bowl, combine melted butter, Italian seasoning, and garlic powder. Brush this mixture generously over the tops of the rolls. Drizzle Italian dressing inside each sandwich for extra moisture and flavor.

Step 4: Wrap each sub sandwich tightly in foil. Bake at 375°F (190°C) for about 15 minutes, or until the cheese is melted and the filling is heated through.
Step 5: Carefully unwrap, slice, and serve the sandwiches warm to enjoy their full, comforting flavor.

Tips & Variations

For a vegetarian option, substitute the meats with grilled vegetables and add extra cheese or a pesto spread.

Use fresh baguette instead of sub rolls for a crustier sandwich.
Try adding sliced tomatoes or roasted red peppers for additional flavor and color.
Brush the rolls with garlic butter before toasting to enhance the aroma and taste.

Storage

Store leftover sandwiches wrapped tightly in foil or plastic wrap in the refrigerator for up to 2 days. Reheat wrapped in foil at 350°F (175°C) for about 10–12 minutes to melt the cheese again and warm everything through. Avoid microwaving to prevent sogginess.
