Sausage Recipe Book: Easy Sausage and Peppers

This Italian-American-style sausage and peppers skillet combines browned pork sausage, sweet bell peppers, onion, and a simple tomato pan sauce. It is a flexible weeknight dinner: serve it in rolls, over polenta, or alongside potatoes, and adjust the pepper flakes to suit your table.

Ingredients

1½ lb (680 g) uncooked Italian pork sausage links, mild or hot
2 tbsp (30 ml) olive oil, divided, only as needed
3 medium bell peppers, about 1 lb (450 g) total, any colors, cored and sliced
1 large yellow onion, about 8 oz (225 g), sliced
3 garlic cloves (9 g), finely chopped
1 cup (240 ml) canned crushed tomatoes
½ cup (120 ml) low-sodium chicken broth or water
1 tbsp (15 ml) balsamic vinegar
1 tsp (1 g) dried oregano
½ tsp (1 g) fennel seeds, lightly crushed, optional
¼ tsp (0.5 g) red pepper flakes, or less to taste
¼ tsp (1.5 g) fine salt, plus more only if needed
¼ tsp (0.5 g) ground black pepper
2 tbsp (8 g) chopped fresh parsley
4 hoagie rolls, about 9 oz (255 g) total, for serving if desired
¼ cup (25 g) finely grated Parmesan, for serving if desired

Instructions

Prepare the ingredients. Set out the sausage, slice the peppers and onion into strips about ¼ inch (6 mm) wide, and chop the garlic and parsley. Measure the tomatoes, broth, vinegar, and seasonings. This preparation takes about 20 minutes; keeping the strips fairly even helps them soften at the same pace.
Brown the sausage. Set a large, heavy skillet or sauté pan over medium heat. Add 1 tablespoon (15 ml) olive oil if the pan is dry, then arrange the sausage links in a single layer. Brown them for about 8–9 minutes, turning every couple of minutes so several sides develop color. They do not need to be fully cooked yet. Transfer them to a plate; leave a thin layer of drippings in the pan, and carefully pour off excess fat if there is more than about 1 tablespoon.
Soften the peppers and onion. Add the remaining 1 tablespoon (15 ml) oil if the pan looks dry, followed by the peppers and onion. Sprinkle with the salt and black pepper. Cook for 7–8 minutes, stirring occasionally, until the onion is beginning to turn translucent and the peppers have softened at the edges but still hold their shape. If browned bits collect on the pan, that is useful flavor; lower the heat if they start to scorch.
Add the aromatics and sauce. Stir in the garlic, oregano, fennel seeds if using, and red pepper flakes. Cook for about 30 seconds, just until fragrant. Add the crushed tomatoes, broth, and balsamic vinegar, and scrape the bottom of the pan with a wooden spoon to loosen the browned bits. The vinegar gives the sauce a mild tang; it should not make the finished dish taste sharply sour.
Simmer until cooked through. Return the sausages and any plate juices to the skillet. Turn them once to coat, bring the sauce to a gentle simmer, then reduce the heat to medium-low and cover loosely. Simmer for 16–18 minutes, turning the links once, until cooked through. Check the center of the thickest sausage with a food thermometer: because these are ground-pork sausages, the USDA FSIS safe minimum internal temperature is 160°F (71°C). If a link has not reached that temperature, continue simmering and check again after a few minutes. The sauce should bubble gently, not boil hard.
Finish and serve. Remove the lid and simmer for 1–2 minutes if you want a thicker sauce. Taste the sauce and adjust the salt or pepper only if needed. Scatter the parsley over the skillet. For sausage rolls, split and warm the rolls, then tuck in a sausage link with peppers and sauce. Pass Parmesan at the table if desired.

Tips

Choose sausage links that fit the pan. Italian pork sausage is easy to find and gives the sauce a savory, seasoned base. Mild sausage keeps the dish gentle; hot links add more heat. If your links are unusually thick, they may need a few extra minutes of simmering, so rely on the thermometer rather than the clock alone.
Keep the vegetables from getting soggy. Slice the peppers into similar-sized strips and give them room in the pan. If your skillet is small, cook the peppers and onion in two batches or use a wider pan. Crowding traps steam and softens the vegetables before they have a chance to pick up flavor.
Use broth or water according to what you have. Low-sodium chicken broth makes the sauce a little fuller, while water keeps the tomato and sausage flavors more direct. Regular salted broth can make the finished pan too salty, so taste before adding any extra salt.
Substitute thoughtfully. If fennel seeds are unavailable, leave them out; the dish will still work, with a less pronounced anise-like aroma. For a sweeter sauce, use a teaspoon of red wine vinegar or omit the balsamic. If using a plant-based sausage, follow its package directions for safe cooking and timing, since products vary and the pork temperature guidance does not apply to every substitute.

Serving Suggestions

For a classic sandwich-style supper, spoon the sausage and peppers into warmed hoagie rolls and add a little Parmesan. A slotted spoon helps keep the rolls from becoming too wet; serve extra sauce on the side for dipping. Toasting the cut sides of the rolls in a dry skillet is optional, but it gives them a sturdier surface that stands up to the filling.

For a fork-and-knife meal, spoon the skillet over creamy polenta, mashed potatoes, or cooked pasta. A bowl of white beans or a simple green salad also pairs well with the tomato sauce and sweet peppers. If you serve it with rice or another plain grain, spoon some of the sauce over the top so the plate does not feel dry. The Parmesan is optional, and chopped parsley adds a fresh finish without changing the basic character of the dish.

Variations

Use different peppers: A mix of red, yellow, and green bell peppers brings a range of sweetness and a colorful look. Green peppers are more assertive and less sweet, so use them when you want a more savory edge. You can replace one bell pepper with a mild poblano, but remove its seeds and membranes if you prefer less heat.

Make it spicier or more aromatic: Increase the red pepper flakes gradually, or use hot Italian sausage and omit the flakes for a less adjustable but straightforward heat. A pinch of smoked paprika adds a subtle smoky note. Avoid adding too many strong seasonings at once; the sausage is already seasoned, and the tomato sauce should support rather than bury it.

Try a different sausage: Chicken or turkey Italian sausage can replace pork, but check the package and cook poultry sausage to 165°F (74°C) in the thickest part. A fully cooked sausage can be added later simply to heat through, following its package directions, while raw sausage needs to be cooked safely. For a meat-free version, use a plant-based sausage and cook it according to the product directions; its texture and browning may differ.

Make the sauce chunkier or smoother: For a chunkier skillet, replace some crushed tomatoes with diced tomatoes. For a smoother sauce, use passata in the same 1 cup (240 ml) quantity. Passata has a more uniform texture and may taste less pulpy, but either option works with the peppers and sausage.

Storage and Reheating

Transfer leftovers to a shallow, covered container and refrigerate within 2 hours of cooking. The sausage and peppers keep for 3–4 days in the refrigerator. Store rolls separately so they do not soak up the sauce. For longer storage, freeze the cooled sausage and peppers with their sauce in a freezer-safe container for up to 2–3 months for best quality; thaw overnight in the refrigerator before reheating.

Reheat a portion in a covered skillet over medium-low heat with a tablespoon or two of water, stirring the sauce and turning the sausage until hot throughout. You can also microwave it in a covered, microwave-safe dish, pausing to stir or turn the pieces. Reheated leftovers should reach 165°F (74°C); check the center of a sausage with a food thermometer. If the sauce has thickened in storage, add a small splash of water or broth rather than heating it uncovered until it dries out.

Frequently Asked Questions

Can I make sausage and peppers ahead?
Yes. Cook the recipe fully, cool it promptly, and refrigerate it in a covered container. Reheat it gently before serving, making sure leftovers reach 165°F (74°C). The peppers will be softer after reheating, but the sauce and sausage hold up well for a make-ahead meal.

How do I know when the sausage is done?
Check the thickest link with a food thermometer. For this recipe’s ground-pork sausage, the safe minimum is 160°F (71°C). Color alone is not a dependable measure, and cutting into every link to judge doneness can let the juices escape.

Can I cook the sausage and peppers without tomatoes?
Yes. Leave out the crushed tomatoes and use about ¾ cup (180 ml) broth instead, then simmer uncovered until the liquid reduces to a light coating. The result will be less saucy and more focused on the browned sausage and vegetables. Taste before adding salt because the sausage and broth both contribute seasoning.

What can I use instead of Italian sausage?
Use another seasoned pork sausage if you like, but expect its herbs and salt level to change the flavor. Plain ground pork is not a direct one-for-one replacement for links unless it is seasoned; for 1½ lb (680 g), season it with salt, pepper, and herbs, form it into small patties, and cook them to 160°F (71°C). A different sausage may also need a different cooking time, so check its temperature and package directions.

Can I make this recipe in a smaller skillet?
A smaller pan can work, but brown the links in batches and cook the peppers and onion in batches if they crowd the surface. Combine everything for the sauce simmer. A crowded skillet steams ingredients and makes browning less effective; a wide pan is simply easier to manage.

Why is my sauce watery?
Peppers release moisture as they cook, and a covered pan holds more of it. Remove the lid and simmer the sauce for a few minutes, stirring occasionally, until it reaches the consistency you want. Keep the heat gentle enough that the tomatoes do not splatter heavily or catch on the bottom.
