Ingredients for Sausage, Peppers & Onions Sandwiches
- 1 1/2 pounds Italian sausage links, mild or hot
- 2 large bell peppers, sliced
- 1 large onion, thinly sliced
- 3 cloves garlic, minced
- 2 tablespoons olive oil
- 1/2 cup chicken broth
- 1 teaspoon Italian seasoning
- 1/2 teaspoon paprika
- 1/2 teaspoon black pepper
- Salt, to taste
- 6 hoagie rolls
- 1/2 cup shredded mozzarella or provolone cheese (optional)
- 2 tablespoons fresh parsley, chopped
How to Make Sausage, Peppers & Onions Sandwiches
Step 1: Brown the Italian Sausage
Heat 1 tablespoon of olive oil in a large skillet over medium-high heat. Add the Italian sausage links and cook for approximately 8–10 minutes, turning occasionally until browned on all sides and cooked through.
For pork sausage, check that the internal temperature reaches 160°F (71°C).
Remove the sausages from the skillet and place them on a cutting board. Let them rest briefly, then slice diagonally into bite-sized pieces.
Step 2: Cook the Peppers and Onions
Add the remaining tablespoon of olive oil to the same skillet. Keep the flavorful browned bits in the pan because they add extra flavor to the vegetables.
Add the sliced bell peppers and onions. Cook for 7–10 minutes, stirring occasionally, until softened and lightly caramelized around the edges.
Step 3: Add the Garlic and Seasonings
Stir in the minced garlic and cook for about 30 seconds, just until fragrant.
Add the Italian seasoning, paprika, black pepper, and salt to taste. Stir well so the vegetables are evenly coated with the seasonings.
Step 4: Simmer Everything Together
Return the sliced sausage to the skillet with the peppers and onions.
Pour in the chicken broth and stir everything together, scraping the bottom of the pan to release the flavorful browned bits.
Let the mixture simmer for 5–7 minutes, or until the broth reduces and creates a light, savory sauce that coats the sausage and vegetables.
Step 5: Toast the Hoagie Rolls
While the filling finishes cooking, slice the hoagie rolls lengthwise.
Toast them lightly in a dry skillet or under the broiler for 1–2 minutes until the edges are golden. Toasting helps the rolls hold the juicy filling without becoming soggy.
Step 6: Assemble the Sandwiches
Fill each toasted hoagie roll generously with the sausage, peppers, and onions.
If desired, sprinkle shredded mozzarella or provolone cheese over the hot filling and allow it to melt.
Finish with freshly chopped parsley and serve immediately while warm.
Tips for the Best Sausage, Peppers & Onions Sandwiches
Choose the right sausage. Mild Italian sausage gives you a classic savory flavor, while hot Italian sausage adds a little extra spice. You can also combine both.
Brown the sausage properly. Don’t rush this step. A golden-brown exterior adds flavor and makes the finished filling taste even better.
Don’t overcrowd the skillet. If necessary, brown the sausages in batches so they develop a nice crust instead of steaming.
Let the vegetables caramelize. Give the peppers and onions enough time to soften and develop golden edges. This brings out their natural sweetness.
Use sturdy rolls. Hoagie rolls or Italian sub rolls are ideal because they hold the filling without falling apart.
Don’t skip the broth. Chicken broth helps combine all the flavors and creates a light sauce that keeps the filling moist.
Toast the bread before filling. A lightly toasted roll gives the sandwich a better texture and helps prevent sogginess.
Delicious Variations
Spicy Italian Sausage Sandwich
Use hot Italian sausage and add a pinch of red pepper flakes when cooking the garlic. Top with sliced hot peppers for an extra kick.
Cheesy Sausage and Peppers Sandwich
Add provolone or mozzarella cheese over the hot sausage filling. Place the assembled sandwiches under the broiler briefly until the cheese is melted and bubbly.
Mushroom and Sausage Sandwich
Add 1 cup of sliced mushrooms when cooking the peppers and onions. They bring an earthy flavor that pairs wonderfully with Italian sausage.
Tomato-Style Sausage and Peppers
For a richer, more traditional Italian-style filling, add a little tomato paste or crushed tomatoes and allow everything to simmer until thickened.
Garlic Butter Hoagie Rolls
Mix softened butter with a little garlic powder and brush it over the cut sides of the rolls before toasting. This adds another layer of delicious flavor.
What to Serve with Sausage, Peppers & Onions Sandwiches
These sandwiches are filling enough to enjoy on their own, but adding a simple side dish makes them even better.
Some delicious options include:
- Crispy French fries or seasoned potato wedges
- Onion rings
- A fresh green salad with vinaigrette
- Roasted potatoes with garlic and rosemary
- Pickled pepperoncini or Italian giardiniera
- Pasta salad
- Coleslaw or a simple vegetable salad
For a casual dinner, serve each sandwich with crispy fries and your favorite dipping sauce.
How to Store and Reheat Leftovers
Refrigerator: Allow the sausage and vegetable filling to cool, then transfer it to an airtight container. Refrigerate for up to 3–4 days. Keep the filling separate from the bread to prevent soggy sandwiches.
Freezer: Place the cooled filling in a freezer-safe container or freezer bag. Freeze for up to 2 months for best quality. Thaw overnight in the refrigerator before reheating.
Stovetop reheating: Transfer the filling to a skillet over medium heat. Add a small splash of chicken broth or water and stir occasionally until heated through.
Microwave reheating: Place a portion of the filling in a microwave-safe dish, cover loosely, and heat in short intervals until thoroughly hot.
For the best results, toast fresh hoagie rolls and assemble the sandwiches just before serving.
Frequently Asked Questions
What kind of sausage is best for sausage and peppers sandwiches?
Italian sausage links are the best choice. Mild or sweet Italian sausage provides a classic savory flavor, while hot Italian sausage gives the sandwich more heat. You can use either depending on your preference.
