What You Need to Make This Italian Sausage with Peppers and Onions
- Italian sausage links (about 1½ lbs) – the main protein; choose mild for family-friendly flavor or hot for extra spice.
- Olive oil – helps brown the sausages and soften the vegetables while adding richness.
- Yellow onion – sliced and cooked until sweet and golden to form the base of the dish.
- Red bell pepper – adds natural sweetness and color.
- Green bell pepper – brings a slightly bitter edge that balances the richness.
- Yellow bell pepper (optional) – another layer of sweetness and vibrant color.
- Garlic cloves – minced to add deep, savory aroma to the sauce.
- Dried oregano – classic Italian herb that seasons the sausage and vegetables.
- Dried basil – adds a gentle, fragrant note to the tomato-based pan sauce.
- Crushed red pepper flakes – optional heat booster for those who like a little kick.
- Salt – brings out the flavors of the sausage and vegetables; adjust to taste.
- Black pepper – adds gentle warmth and depth.
- Chicken broth or dry white wine – deglazes the pan, lifts all the browned bits, and forms a light sauce.
- Tomato paste – optional but great for a richer, slightly thicker sauce with a hint of tomato.
- Fresh parsley – sprinkled on at the end for color and freshness.
- Hoagie rolls, cooked pasta, or rice – optional serving base to turn the skillet into a full meal.
Step-by-Step Italian Sausage with Peppers and Onions
STEP 1: Set a large, heavy skillet over medium heat and add about half the olive oil. Lay in the Italian sausage links and sear them on all sides until nicely browned, about 7–8 minutes total. Transfer to a plate.
STEP 2: In the same skillet, add the remaining olive oil. Tip in the sliced onions and all the bell peppers. Cook, stirring occasionally, for 5–7 minutes until they soften and develop a light golden edge.
STEP 3: Stir in the minced garlic and cook for about 30–60 seconds, just until fragrant. Sprinkle the vegetables with dried oregano, dried basil, red pepper flakes if using, salt, and black pepper. Toss to coat everything evenly.
STEP 4: Slice the browned sausages into 2–3 inch pieces, or leave them whole if you prefer. Return them to the skillet, nestling them down into the vegetables so they’re evenly distributed.
STEP 5: Pour in the chicken broth or white wine, scraping the bottom of the pan with a wooden spoon to release any browned bits. If you’re using tomato paste, stir it in now until the liquid turns a light red color.
STEP 6: Reduce the heat to low, cover the skillet, and let everything simmer gently for 15–20 minutes. The sausages should be cooked through, and the sauce should taste rich and well-seasoned.
STEP 7: Taste the sauce and adjust the seasoning with extra salt, pepper, or red pepper flakes if needed. Sprinkle with chopped fresh parsley, then serve hot over hoagie rolls, pasta, rice, or simply in bowls.
Can I make this ahead of time?
Yes. Cook the dish completely, cool it, and refrigerate in an airtight container for up to 3 days. Reheat gently on the stovetop, adding a splash of broth or water to loosen the sauce if needed.
What kind of Italian sausage works best?
Use pork Italian sausage links, either mild or hot depending on your family’s taste. You can also mix mild and hot sausages in the same pan for a balanced, slightly spicy flavor.
Can I use pre-cooked sausage?
You can. Skip the initial browning time or just sear briefly for color, then add the sliced pre-cooked sausage when the vegetables are soft. Simmer long enough to heat everything through and blend the flavors.
How do I keep the peppers from turning mushy?
Cook the peppers over medium heat until just tender, not collapsed, and avoid over-simmering at high heat. Leaving the pieces slightly thicker also helps them stay crisp-tender instead of getting overly soft.
Is this dish spicy?
The spice level depends on your sausage and whether you add red pepper flakes. Use mild sausage and skip the flakes for a gentle dish, or choose hot sausage and extra flakes for a bolder kick.
Helpful Tips
- Brown well, not burnt: Take time to get good color on the sausages without scorching them; those browned edges add a lot of flavor to the sauce.
- Don’t rush the simmer: The 15–20 minute covered simmer lets the sausages finish cooking and the broth, tomato, and seasonings blend together.
- Adjust the liquid: If you like more sauce, add an extra splash of broth or wine toward the end and warm it through before serving.
Serving Ideas for Italian Sausage with Peppers and Onions
- Classic sandwich style: Tuck sausage and peppers into toasted hoagie rolls, add a spoonful of the pan sauce, and top with a sprinkle of provolone or mozzarella if you like it cheesy.
- Over pasta or rice: Spoon everything over al dente pasta or fluffy rice to soak up the sauce. A side of garlic bread or a green salad makes it feel like a complete plate.
- Lighter presentation: Serve the sausage and vegetables in shallow bowls with a side of roasted potatoes, polenta, or a simple mixed salad for a more low-carb, fork-and-knife style dinner.
How to Store & Reheat
Leftovers keep well and often taste even better the next day as the flavors meld.
Allow the sausage and peppers to cool to room temperature, then transfer to an airtight container. Store in the refrigerator for up to 3 days. For longer storage, you can freeze the mixture in freezer-safe containers or heavy-duty bags for up to 2 months.
When you’re ready to eat, thaw frozen portions overnight in the fridge if possible. Reheat gently in a covered skillet over low to medium-low heat, adding a splash of broth or water to loosen the sauce and prevent sticking. You can also reheat individual portions in the microwave in short bursts, stirring once or twice, until hot all the way through.
Serve again on rolls, over pasta, or however you enjoyed it the first time—this is exactly the kind of dish that makes leftovers something to look forward to.
Italian Sausage with Peppers and Onions
Ingredients
- 680 grams 1 ½ pounds Italian sausage links, either mild or spicy
- 1 red bell pepper thinly sliced
- ½ teaspoon freshly ground black pepper
- ½ cup low-sodium chicken broth or a dry white wine substitute
- 1 large yellow onion thinly sliced
- 2 tablespoons extra virgin olive oil divided
- ½ teaspoon sea salt or to preference
- 3 cloves garlic finely chopped
- 1 green bell pepper sliced into strips
- 1 teaspoon dried oregano leaves
- Fresh parsley chopped, for garnish
- ¼ teaspoon crushed red chili flakes optional
- 1 tablespoon tomato paste optional for added depth
- 1 yellow bell pepper optional, sliced
- ½ teaspoon dried basil
- Toasted hoagie rolls steamed rice, or pasta, optional for serving
Instructions
- Warm one tablespoon of olive oil in a large skillet set over medium heat. Add the sausage links and sear them until they are deeply browned on all sides, approximately 7–8 minutes. Remove the sausages from the skillet and set them aside; they do not need to be cooked through at this stage.
- Pour the remaining tablespoon of oil into the same skillet. Add the sliced onions and all bell pepper varieties. Sauté for 5 to 7 minutes, stirring occasionally, until they become tender and begin to caramelize. Mix in the minced garlic and cook for one additional minute until fragrant.
- Incorporate the dried oregano, basil, crushed red pepper flakes (if using), salt, and black pepper. Toss to evenly distribute the seasonings throughout the vegetables.
- Slice the browned sausage links into pieces about 2 to 3 inches in length, or leave them whole if preferred. Return them to the skillet and add the chicken broth along with the optional tomato paste. Stir gently to combine. Cover and simmer the mixture over low heat for 15 to 20 minutes, or until the sausages are fully cooked and the flavors have blended thoroughly.
- Scatter freshly chopped parsley over the finished dish. Serve warm, either on hoagie rolls, over rice, with pasta, or enjoy as a standalone entrée.
