How to Make Italian Sausage & Peppers Subs

Step 1: Prepare the Sausage

Start by slicing the Italian sausage into bite-sized pieces or remove from casings if preferred. Cook the sausage in a large skillet over medium-high heat until browned and cooked through, about 7-10 minutes. Remove and set aside.

Step 2: Sauté the Peppers and Onions

In the same skillet, drizzle olive oil and add thinly sliced bell peppers and onions. Cook over medium heat for 8-10 minutes until the vegetables are soft and lightly caramelized. Add minced garlic during the last two minutes for maximum aroma.

Step 3: Combine and Season

Return the cooked sausage to the skillet with the peppers and onions. Toss everything together and season with salt and pepper to taste. Let the mixture heat through for about 2-3 minutes to blend the flavors.

Step 4: Assemble the Subs

Slice the sub rolls lengthwise, being careful not to cut all the way through. Spoon the sausage and pepper mixture evenly into each roll. Top with slices of provolone or mozzarella cheese while everything is still hot, letting it melt slightly.

Step 5: Serve and Enjoy

Serve the Italian Sausage & Peppers Subs hot for the best flavor and texture. Add any optional garnishes or condiments you like, then dig in!

Pro Tips for Making Italian Sausage & Peppers Subs

• Use Fresh Sausage: Fresh Italian sausage delivers the best flavor and juiciness compared to pre-cooked options.
• Don’t Rush the Sauté: Cooking peppers and onions slowly ensures they become sweet and tender, adding depth to the sandwich.
• Toast the Bread: Lightly toasting your sub rolls adds crunch and helps prevent sogginess from the filling.
• Cheese Choice Matters: Provolone melts smoothly and complements both sausage and peppers perfectly.
• Rest Before Serving: Letting the sandwich sit for a minute helps settle the flavors and prevents fillings from spilling out.

Garnishes

Fresh basil or parsley can add a pop of color and herbaceous brightness. A drizzle of spicy mustard or a swipe of garlic aioli also makes a flavorful finish.

Side Dishes

Pair your subs with classic sides such as crispy French fries, a crunchy garden salad, or creamy coleslaw to round out your meal.

Creative Ways to Present

Cut the subs into smaller sliders for parties or serve open-faced with a sprinkle of Parmesan for a rustic, Italian-inspired look.

Make Ahead and Storage

Storing Leftovers

Wrap leftover Italian Sausage & Peppers Subs tightly in foil or plastic wrap and refrigerate for up to 3 days to maintain freshness and flavor.

Freezing

For longer storage, assemble the filling separately and freeze in an airtight container. Freeze the bread separately to avoid sogginess, and reheat components before assembling.

Reheating

Reheat leftovers in a skillet or oven at medium heat to retain texture, or microwave briefly with a damp paper towel cover to keep the sandwich moist.

FAQs

Fresh, sturdy sub rolls or hoagie rolls that hold up to juicy fillings without getting soggy are ideal choices.
