Full Recipe: 

Ingredients

For the Sausage and Peppers

  • 2 tablespoons oil

  • 2 lbs sweet Italian sausage links

  • 2 bell peppers, sliced

  • 2 onions, sliced

  • 3 cloves garlic, minced

  • 15 oz can tomato sauce

  • 14.5 oz can diced tomatoes with juice

  • ½ teaspoon salt

  • 1 teaspoon Italian seasoning

  • 1 teaspoon onion powder

  • 1 tablespoon brown sugar

For the Hoagie Subs

  • Hoagie buns

  • Provolone cheese slices

  • Parmesan cheese (for topping)

Directions

  1. Brown the Sausages:
    In a large skillet, heat the oil over high heat. Brown the sausages well on all sides until a good amount of color is developed, about 5-7 minutes. Remove the sausages from the skillet and set aside.

  2. Cook the Vegetables:
    In the same skillet, add the sliced bell peppers and onions. Cook for about 5 minutes, allowing them to get some color. Add the minced garlic and cook for another minute.

  3. Simmer the Sausages:
    Add the sausages back to the skillet with the cooked vegetables. Pour in the tomato sauce, diced tomatoes with juice, salt, Italian seasoning, onion powder, and brown sugar. Bring to a boil, then reduce to low heat and simmer for an hour, until the sausages are cooked through.

  4. Prepare the Hoagie Buns:
    While the sausages are simmering, preheat your oven’s broiler. Toast the hoagie buns in the oven on both sides. Once toasted, place the provolone cheese slices inside each bun and return to the oven to broil until the cheese melts.

  5. Assemble the Subs:
    Once the sausages are done, slice them into smaller pieces (if desired). Spoon the sausage and pepper mixture into each toasted hoagie bun. Top with a generous sprinkle of parmesan cheese.

  6. Serve:
    Serve the sandwiches immediately with some of the tomato sauce from the skillet on the side for dipping.

Slow Cooker Option:
After browning the sausages and vegetables, place everything into a slow cooker and cook on low for 5 hours. Serve the same way as above.

The Comfort of Italian Sausage and Peppers

Italian sausage and peppers is a beloved dish in Italian-American cuisine, and it’s no surprise why. The combination of juicy, savory sausages with the sweetness of bell peppers and the richness of caramelized onions creates a symphony of flavors that are both hearty and satisfying. The sausage itself is the heart of the dish—its savory, spiced profile adds depth to the overall flavor. When combined with the sweetness of the peppers and onions, it creates a balanced taste that’s familiar yet comforting.

Cooking the sausages until they develop a beautiful, golden-brown crust helps to lock in their juices, ensuring that each bite is packed with flavor. Adding the peppers and onions to the skillet allows their natural sugars to caramelize, creating a savory-sweet mixture that complements the sausage perfectly. Whether you’re simmering everything together or cooking it separately, the combination of these ingredients is the backbone of the sub, and it’s what makes this dish such a crowd-pleaser.

Sausage Variations: Choosing the Right Flavor

While sweet Italian sausages are the traditional choice for this dish, there are plenty of ways to customize the flavor profile based on your preferences. For those who like a bit of heat, you can opt for spicy Italian sausage instead of the sweet variety. The spicy sausage will add a kick of heat that contrasts beautifully with the sweetness of the bell peppers and onions.

Another variation is to mix different types of sausages to create a more complex flavor. For example, combining sweet sausage with a bit of fennel sausage can add additional layers of flavor. Fennel seeds are often used in Italian sausages, and they offer a mild anise-like flavor that works well with the peppers and onions. No matter the variety of sausage you choose, it’s important to use high-quality sausages to ensure the best flavor and texture.

Cooking on the Stovetop vs. Slow Cooker: The Versatility of the Dish

One of the best things about Italian Sausages with Peppers & Onions is the flexibility of how it can be prepared. Whether you prefer the stove-top method, which offers faster results and more control over the cooking process, or the slow cooker method, which allows for a longer, more relaxed cooking experience, the dish will be equally delicious.

On the stovetop, the sausages are first browned in oil, which creates a flavorful base that enhances the final dish. The bell peppers and onions are cooked in the same skillet, allowing their flavors to mingle with the sausage drippings. Once everything is combined with the tomato sauce and simmered, the result is a rich, savory mixture that is perfect for spooning onto toasted hoagie buns.

For those who prefer the slow cooker method, the process is just as straightforward. After browning the sausages and vegetables, everything is added to the slow cooker, where it simmers for hours, developing deeper flavors. The slow cooker method is ideal for busy days when you want to prepare the dish in the morning and let it cook while you’re occupied with other tasks. The long, slow cooking time allows the sausages to absorb all the flavors of the peppers, onions, and tomato sauce, creating a truly flavorful filling for the subs.

The Role of Tomato Sauce and Seasonings

The tomato sauce is a crucial component of the Italian Sausages with Peppers & Onions dish. It ties the sausages, peppers, and onions together, adding moisture and depth to the overall dish. A combination of tomato sauce and diced tomatoes with juice provides the right balance of acidity and sweetness, making the sauce a perfect complement to the savory sausages and vegetables.

Seasonings like Italian seasoning, onion powder, and a touch of brown sugar bring everything together. The Italian seasoning adds classic herb flavors that enhance the overall dish, while the brown sugar balances the acidity of the tomato sauce and brings out the natural sweetness of the bell peppers and onions. Together, these ingredients create a flavorful sauce that coats the sausages and vegetables, adding richness and depth to each bite.

The Hoagie Bun: The Perfect Vessel for the Filling

While the filling is undoubtedly the star of the dish, the hoagie bun is just as important in making the perfect sub. The right bun can elevate the dish, adding texture and holding the filling together without falling apart. A good hoagie bun should be soft yet sturdy enough to handle the juicy sausage and vegetables. It should also have a slightly crispy exterior when toasted, providing the perfect contrast to the tender filling.

Toasting the hoagie buns before assembling the subs ensures that the bread stays firm and holds up to the sauce without becoming soggy. The addition of provolone cheese slices to the toasted buns adds richness and creaminess, while the Parmesan cheese topping brings an additional layer of savory, umami flavor. The melted cheese on top of the sausage and pepper mixture ties everything together, creating a melt-in-your-mouth experience with every bite.

Garnishes and Toppings: Adding Flavor and Texture

To make these Italian Sausages with Peppers & Onions even more satisfying, consider adding a few simple garnishes and toppings. A sprinkle of fresh herbs, such as basil or oregano, adds a burst of freshness that complements the richness of the sausage and cheese. If you prefer a bit of heat, a drizzle of hot sauce or a few red pepper flakes can add a spicy kick to balance out the sweetness of the peppers.

Some variations of this sandwich also include sautéed mushrooms or olives for extra texture and flavor. For those who like a tangy contrast, pickled vegetables, such as giardiniera, can be added for a pop of acidity. These simple additions can elevate the sandwich and provide different flavor profiles, depending on personal preferences.

Perfect for Any Occasion

These Italian Sausages with Peppers & Onions subs are versatile enough to be enjoyed in a variety of settings. Whether it’s a weeknight dinner for the family, a casual lunch with friends, or a party treat, these subs are sure to please a crowd.
