This Italian-American-inspired hot sausage skillet combines spicy sausage with sweet bell peppers, tomatoes, and creamy white beans for a filling one-pan meal. It comes together in about an hour, and the tomatoes and broth turn the browned sausage drippings into a savory sauce that is easy to serve with bread, pasta, or rice.
Ingredients
- 1 tablespoon (15 ml) olive oil
- 1½ pounds (680 g) bulk hot Italian sausage
- 1 medium yellow onion (about 150 g), thinly sliced
- 2 medium bell peppers (about 300 g total), cored and sliced; use any colors
- 3 cloves garlic (about 9 g), finely chopped
- 1 teaspoon (2 g) dried oregano
- ½ teaspoon (1 g) fennel seeds, lightly crushed (optional)
- ¼ teaspoon (0.5 g) red pepper flakes, optional
- 1 can (14½ ounces / 411 g) diced tomatoes, with their juices
- ½ cup (120 ml) low-sodium chicken broth or water
- 1 can (15 ounces / 425 g) cannellini beans, drained and rinsed
- ½ teaspoon (3 g) kosher salt, plus more to taste
- ¼ teaspoon (0.5 g) freshly ground black pepper
- 1 tablespoon (15 ml) red wine vinegar
- 2 tablespoons (8 g) chopped fresh parsley, for serving
- ¼ cup (25 g) finely grated Parmesan, for serving (optional)
Instructions
-
Prepare the vegetables. Slice the onion and bell peppers, chop the garlic, and drain and rinse the beans. Set everything beside the stove before cooking; once the sausage is browned, the rest of the skillet moves quickly. If your sausage is in links rather than bulk, remove the casings and crumble the meat.
-
Brown the sausage. Heat the olive oil in a large, deep skillet or Dutch oven over medium-high heat. Add the sausage and break it into bite-size pieces with a wooden spoon. Cook for 8 to 10 minutes, stirring occasionally, until browned and no longer pink. Check the thickest pieces with a food thermometer: the USDA FSIS safe minimum internal temperature for ground meat is 160°F (71°C). If it has not reached that temperature, keep cooking and check again. If there is more than about 1 tablespoon of rendered fat in the pan, spoon off the excess, leaving the browned bits behind.
-
Soften the peppers and onion. Add the sliced onion and peppers to the skillet. Cook for about 8 minutes, stirring now and then, until the vegetables soften and pick up some color. If the pan seems dry or the vegetables begin sticking before they soften, add a tablespoon of water and lower the heat slightly. The vegetables do not need to be completely tender yet; they will cook further in the sauce.
-
Add the aromatics. Stir in the garlic, oregano, crushed fennel seeds if using, red pepper flakes if using, salt, and black pepper. Cook for about 30 seconds, stirring constantly, just until the garlic smells fragrant. Avoid letting it brown, which can make it taste bitter.
-
Simmer the tomato sauce. Pour in the diced tomatoes and their juices along with the broth. Scrape the bottom of the pan with your spoon to loosen the browned sausage bits. Bring the mixture to a gentle simmer, then reduce the heat to medium-low and cook uncovered for 12 minutes, stirring once or twice. The peppers should become tender and the tomato liquid should reduce slightly without drying out.
-
Finish with the beans. Fold in the drained beans and simmer for another 6 to 7 minutes, until they are hot and the sauce clings to the sausage and vegetables. Stir in the red wine vinegar, taste, and add more salt or pepper if needed. The vinegar brightens the rich sauce; add it gradually if you prefer a milder tang.
-
Garnish and serve. Take the pan off the heat. Scatter parsley and Parmesan over the top, if desired, and bring the skillet to the table while hot. If the sauce thickens too much before serving, stir in a splash of broth or water. If it looks thinner than you like, simmer it for a few more minutes before adding the parsley.
Tips
- Choose the sausage heat level you enjoy. Hot Italian sausage varies by maker and can range from pleasantly peppery to quite fiery. If you are unsure, use a mix of hot and mild sausage, or start with mild sausage and add a small pinch of red pepper flakes. Taste only after the meat is fully cooked, and remember that Parmesan can soften the impression of heat a little.
- Let the sausage brown before stirring constantly. Give the crumbles a minute or two against the hot pan so they develop browned edges. Those bits add flavor to the vegetables and sauce. Keep the pieces small enough to distribute through the dish, but avoid repeatedly crushing them into a paste.
- Adjust the liquid to your pan and tomatoes. Canned tomatoes differ in how much juice they contain, and a wide skillet evaporates liquid faster than a narrow pot. Keep the pan uncovered for a saucier, concentrated finish; add a few tablespoons of broth if it becomes too thick. Use water in place of broth if needed, though the flavor will be a little less savory.
- Use a thermometer rather than color alone. Sausage can brown on the outside before the center is safely cooked. Check several of the largest crumbles with a food thermometer and cook until they reach 160°F (71°C). If substituting poultry sausage, cook it to 165°F (74°C), the USDA FSIS safe minimum for poultry.
Serving Suggestions
For a simple dinner, serve the sausage, peppers, and beans in shallow bowls with crusty bread to catch the tomato sauce. Toasted rolls also work well, especially if you spoon the mixture into them like a hearty sausage sandwich. For a more substantial plate, serve it over cooked pasta, polenta, or rice; short pasta such as rigatoni or shells holds the chunky sauce particularly well. A crisp green salad or lightly dressed arugula balances the richness without adding another heavy side.
Offer grated Parmesan, chopped parsley, and extra red pepper flakes at the table so each person can adjust their bowl. If the dish is part of a larger meal, a modest serving alongside roasted vegetables is satisfying. Keep bread or pasta separate from the skillet if you expect leftovers, since it can absorb the sauce and become soft during storage.
Variations
Make it milder: Replace half or all of the hot sausage with mild Italian sausage, and leave out the optional pepper flakes. For a gentler flavor while retaining some spice, use 1 pound (454 g) hot sausage and ½ pound (227 g) mild sausage. The overall dish will still have a warm, savory flavor.
Swap the beans: Great Northern beans or butter beans work in place of cannellini beans in the same quantity. Chickpeas are firmer and hold their shape, while kidney beans have a more assertive texture. For a bean-free version, leave them out and serve the sausage mixture over pasta or rice; add a little extra broth if you want more sauce.
Add greens: Stir in 3 cups (90 g) baby spinach during the final 2 minutes, or add 4 cups (120 g) chopped kale when you add the tomatoes and allow it to simmer until tender. Kale needs more time than spinach and may require a small splash of extra broth. Finish with the vinegar after the greens have softened.
Use fresh tomatoes in season: Replace the canned tomatoes with about 2 cups (300 g) chopped ripe tomatoes. They may release less liquid, so add another ¼ cup (60 ml) broth if the skillet looks dry. The sauce will generally be less uniform and may taste fresher and lighter than the canned-tomato version.
Storage and Reheating
Refrigerate leftovers within 2 hours of cooking. Transfer them to a shallow, airtight container and store for 3 to 4 days. If you have served the dish over pasta, store the pasta separately when possible so it does not soak up all the sauce. Let the food stop steaming heavily before sealing the container, but do not leave it out to cool for an extended period.
For longer storage, freeze the sausage mixture in airtight, freezer-safe containers for up to 3 months for best quality. Thaw it overnight in the refrigerator, or reheat it from frozen over low heat with a splash of broth, stirring as it loosens. Beans can soften somewhat after freezing, but the flavor remains suitable for a quick meal.
Reheat a portion in a covered saucepan over medium-low heat, stirring occasionally and adding a little water or broth if needed. You can also microwave it in a covered, microwave-safe dish, stirring halfway through. Reheat leftovers to 165°F (74°C), checking the center with a food thermometer. Heat only the portion you plan to serve, rather than repeatedly warming and cooling the full batch.
Frequently Asked Questions
How spicy is hot Italian sausage?
Heat varies from one sausage to another, so there is no single level that applies to every package. The peppers and beans in this recipe mellow the sausage somewhat, but the skillet will still taste spicy. For a cautious first try, use half hot and half mild sausage and omit the red pepper flakes.
Can I make this with sausage links?
Yes. Remove the casings and crumble the raw sausage into the pan, then cook it as directed and verify that it reaches 160°F (71°C). If you would rather keep the links whole, brown them in the skillet and cook them through to the same safe temperature, then slice them before returning them to the sauce. Whole links take longer depending on their size, so use the thermometer rather than relying only on the listed browning time.
Can I prepare the recipe ahead?
You can slice the onion and peppers and chop the garlic up to a day ahead, keeping them covered in the refrigerator. You can also cook the complete skillet ahead and refrigerate it promptly; the flavors meld as it rests. Reheat gently with a splash of broth and bring the leftovers to 165°F (74°C) before serving.
What can I use instead of cannellini beans?
Great Northern beans and butter beans are the closest easy substitutes, and canned chickpeas also work if you want a firmer bite. Drain and rinse whichever canned beans you choose before adding them. Lentils are less interchangeable because their size and texture change the balance of the dish; use cooked lentils and fold them in gently at the end.
Why is my skillet watery?
Tomatoes can release different amounts of liquid, and a covered pan traps steam instead of reducing the sauce. Simmer uncovered for a few extra minutes, stirring so the bottom does not catch. If the sausage and vegetables are already tender, keep the heat moderate and avoid boiling hard; a steady gentle simmer concentrates the sauce without breaking down the beans too much.
