This baked Italian sub is the ultimate hot sandwich when you crave bold deli flavors with gooey melted cheese. Layered with capicola, ham, salami, pepperoni, and rich Fontina cheese plus briny peppers all tucked into a golden toasted hoagie, it is my go-to for a quick dinner or a cozy weekend lunch. You can serve it thick and melty from the oven or leave it cold and crisp for a picnic-style meal.

I first made this sub for a game day crowd and everyone raved about the toasted bread and zippy peppers it was gone before halftime and now it is my last-minute entertaining move every time

Ingredients

  • Italian sub loaf: from a deli ensures a crusty exterior that holds up under lots of fillings look for one with a light chewy interior
  • Italian dressing: provides moisture and tang choose high-quality with visible herbs and real olive oil
  • Pepperoncini peppers: sliced for a bright punchy heat pick ones that are crisp not mushy
  • Marinated roasted red peppers: sliced thin add sweetness and depth find jars packed in oil with garlic
  • Capicola ham: sliced super thin for distinctive Italian flavor ask the counter to slice it fresh if possible
  • Ham: classic deli cut adds salty depth opt for smoked or honey ham if you like subtle sweetness
  • Salami: brings savory and spicy notes go for Genoa or hard salami cut as thin as possible
  • Pepperoni: extra bite and richness seek out a deli variety with visible flecks of spice
  • Fontina cheese: creamy meltiness with earthy notes you want it paper thin so it melts evenly
  • Red pepper flakes: sprinkle for desired heat adjust to your spice level by adding before or after baking

Step-by-Step Instructions

Prepare the Oven:
Preheat your oven to 350°F and line a baking sheet with parchment paper so the bottom gets crisp without sticking
Slice and Dress the Bread:
Slice the Italian sub loaf in half lengthwise using a sharp serrated knife do not cut all the way through You want to butterfly it so it opens but stays connected at the bottom edge Spread the Italian dressing generously over both inside surfaces using a pastry brush to reach the corners
Add the Vegetables:
Layer the sliced pepperoncini peppers and marinated roasted red peppers evenly across the dressed bread pressing them gently into the dressing so they do not slip out later
Layer the Meats and Cheese:
Spread the capicola ham salami and pepperoni slices out in a wavy pattern for the best texture Follow with folded ham and top generously with thin slices of Fontina cheese making sure cheese touches both sides of bread
Season and Bake:
Sprinkle a pinch of red pepper flakes over the fillings This will infuse extra spice as it bakes Place the assembled sandwich open-faced on your lined sheet Bake for 10 to 13 minutes until the cheese bubbles and edges of the bread turn crisp and golden
Serve Hot:
Remove from the oven and close the sub by folding the top back over Slice in half to share or leave whole for dramatic effect Eat while hot for the best texture though it is also delicious at room temperature

My favorite part of this recipe is the Fontina cheese It melts luxuriously and turns almost stringy when hot My kids always sneak a slice while I am layering the meats The first time I made this for family movie night it disappeared before the previews even ended

Storage Tips

Store leftovers tightly wrapped in foil in the fridge for up to two days Reheat in a low oven so the bread crisps and cheese re-melts Microwaving is quick but will make the bread softer if you go that route

Ingredient Substitutions

Swap Fontina for provolone or mozzarella if preferred You can use turkey or mortadella for a lighter or different flavor profile Pickled banana peppers are a good swap for pepperoncini if needed

Serving Suggestions

Slice into smaller pieces and serve as party appetizers or pair with tomato soup and a simple green salad for a hearty meal I love loading it up with extra peppers if I am serving with a sweet or creamy soup
