Sausage No Casing Recipes: Italian Sausage and Peppers

This Italian-style sausage and peppers skillet makes flavorful loose sausage from ground pork, fennel, garlic, and pantry spices—no casings or special equipment needed. Simmered with sweet peppers and tomatoes, it is an adaptable one-pan dinner to spoon over pasta, polenta, or bread.

Ingredients

1¼ lb (567 g) ground pork, preferably not extra-lean
1 tbsp (15 ml) olive oil
1 tsp (6 g) kosher salt
1 tsp (2 g) fennel seeds, lightly crushed
1 tsp (2 g) sweet paprika
1 tsp (1 g) dried oregano
½ tsp (1 g) freshly ground black pepper
¼ tsp (0.5 g) red pepper flakes, or more to taste
1 medium yellow onion (about 150 g), thinly sliced
2 medium bell peppers (about 300 g total), any colors, cored and sliced
3 garlic cloves (about 9 g), finely chopped
1 tbsp (16 g) tomato paste
1 can (14.5 oz / 411 g) crushed tomatoes
½ cup (120 ml) water or unsalted chicken broth
1 tbsp (15 ml) red wine vinegar
¼ cup (15 g) chopped fresh parsley
⅓ cup (30 g) finely grated Parmesan, for serving (optional)

Instructions

Prepare the seasoning and vegetables. In a small bowl, combine the salt, fennel, paprika, oregano, black pepper, and red pepper flakes. Crush the fennel with the back of a spoon or briefly grind it if you want a finer, more even seasoning. Slice the onion and peppers, chop the garlic, and keep the ingredients near the stove; having them ready makes the short cooking stages easier to manage.
Season and brown the pork. Put the ground pork in a bowl, scatter the spice mixture over it, and mix gently with your fingers or a fork until the seasonings are distributed. Heat the olive oil in a large, heavy skillet over medium-high heat. Add the pork and break it into bite-size crumbles with a wooden spoon. Cook for about 10 minutes, stirring and turning the pieces so they brown on several sides. Ground pork must reach 160°F (71°C), the USDA FSIS safe minimum temperature for ground meat; check the thickest larger pieces with a food thermometer and continue cooking if needed. Browning adds savory flavor, but the meat does not need to form a single crust.
Soften the peppers and onion. Add the sliced onion and bell peppers to the skillet. Stir to coat them in the pork drippings and cook for 8 minutes, stirring every minute or two. The vegetables should begin to soften while still holding their shape. If the bottom of the pan looks dry or the vegetables start sticking, lower the heat slightly and add a tablespoon of water rather than pouring in extra oil.
Build the tomato sauce. Stir in the garlic and tomato paste and cook for 1 minute, mixing so the paste coats the pork and vegetables without scorching. Add the crushed tomatoes and water or broth, then scrape the bottom of the pan to loosen any browned bits. Bring the mixture to a gentle simmer, reduce the heat to medium-low, and cook uncovered for 16 minutes. Stir occasionally. The sauce is ready when it thickens enough to cling to the meat and peppers; if it becomes thicker than you like, loosen it with a small splash of water.
Finish and serve. Stir in the vinegar and parsley. Taste a spoonful and adjust with a little more salt, pepper, or red pepper flakes if needed. Let the skillet stand for a minute while you prepare the plates, then serve hot with Parmesan if desired. The vinegar brightens the tomato sauce, so add it before deciding whether the dish needs more salt.

Tips

Keep the texture loose. Break the pork into small crumbles as it cooks, but do not mash it continuously. Leaving some pieces a little larger gives the finished skillet a satisfying, sausage-like bite. If you prefer a finer texture for pasta sauce, keep breaking the meat up with the spoon.
Choose pork with some fat. Very lean ground pork can turn dry before it browns. Regular ground pork works well; if using lean pork, watch the pan closely and add a teaspoon of oil if it looks dry. Do not drain the drippings unless there is an unusually large amount, because they carry seasoning and help coat the vegetables.
Adjust the heat in stages. The listed red pepper flakes make a gently warm sauce rather than an especially hot one. For a mild family meal, leave them out; for more heat, add a pinch at the end so you can judge the finished flavor. Smoked paprika can replace sweet paprika, but it will give the dish a smoky note that is less typical of a classic Italian-style seasoning profile.
Use the right pan and avoid crowding. A 12-inch (30 cm) skillet gives the pork room to brown and the vegetables room to soften. In a smaller pan, brown the pork in two batches; crowding traps moisture and makes the meat steam instead of develop browned edges.

Serving Suggestions

This skillet is saucy enough to serve as a main dish, but it is also easy to turn into a more filling meal. Spoon it over cooked pasta, such as rigatoni, penne, or spaghetti, and add a little pasta cooking water if you want the sauce to coat the noodles more easily. Creamy polenta is another good base: its mild flavor balances the fennel and pepper, and it catches the tomato sauce. For a simpler supper, serve it with crusty bread to scoop up the juices.

For a plate with a fresh contrast, add a green salad dressed with olive oil and vinegar, or serve steamed green beans alongside. If using Parmesan, add it at the table so each person can choose how much to use. Leftover skillet filling can also go into toasted rolls; drain or spoon off excess sauce first so the bread does not become soggy.

Variations

Make it with ground turkey or chicken: Substitute an equal weight of ground turkey or chicken for the pork. These meats are leaner, so add 1 extra teaspoon (5 ml) of olive oil if the pan seems dry. Cook poultry to 165°F (74°C), the USDA FSIS safe minimum internal temperature for poultry, measured with a food thermometer. The result is lighter in texture and less rich than the pork version, but the fennel, paprika, and garlic still provide the familiar sausage-style seasoning.

Use prepared sausage meat: If you have loose Italian sausage meat without casings, use 1¼ lb (567 g) in place of the seasoned pork and omit the salt and dry spices at first. Brown it as directed, then taste the sauce before adding more seasoning; commercial or butcher-made sausage can already be quite salty or spicy. Casing-free links can also be slit and squeezed out of their casings, but check that the filling is plain sausage meat rather than a pre-cooked product.

Add mushrooms or greens: Cook 8 oz (225 g) sliced mushrooms with the peppers, allowing their liquid to evaporate before adding the tomatoes. For greens, stir in 3 packed cups (90 g) baby spinach during the last 2 minutes of simmering, or add 2 cups (120 g) chopped kale with the tomatoes and simmer until tender. These additions change the amount of sauce and its texture slightly; add a splash of broth if the pan becomes too dry.

Make a milder, sweeter version: Use one red and one yellow bell pepper, leave out the red pepper flakes, and choose sweet paprika. The peppers bring natural sweetness without adding sugar. To make the skillet more tomato-forward, increase crushed tomatoes to 2 cups (480 g) and simmer a few minutes longer until the sauce is thick again.

Storage and Reheating

Refrigerate leftovers within 2 hours of cooking, using a shallow, covered container so they cool promptly. The cooked pork and pepper mixture keeps for 3–4 days in the refrigerator. Store pasta, polenta, or bread separately where possible; keeping the base and sauce apart helps prevent pasta from soaking up all the liquid.

For longer storage, freeze the cooled skillet mixture in a sealed, freezer-safe container for up to 3 months for best quality. Thaw it overnight in the refrigerator, or reheat from frozen in a covered saucepan over low heat with a splash of water, stirring as it loosens. Reheat leftovers until they reach 165°F (74°C), the USDA FSIS recommended temperature for reheated leftovers, checking with a food thermometer. On the stovetop, warm over medium-low heat and stir often; in a microwave, cover loosely, heat in short intervals, and stir between intervals so the center heats evenly.

Frequently Asked Questions

What does “sausage without casing” mean?

It usually means sausage filling that has not been stuffed into a tube-shaped casing. You can buy loose sausage meat, remove the casing from fresh links, or season plain ground meat at home as in this recipe. The filling can be browned as crumbles, shaped into patties, or added to sauces and casseroles.

Can I make this recipe with ground beef?

Yes. Replace the pork with the same weight of ground beef and keep the seasonings and vegetables the same. Beef has a different flavor and may release more or less fat depending on its leanness. Drain excess fat if necessary, but leave a thin coating in the skillet for the vegetables. Cook ground beef to 160°F (71°C), the USDA FSIS safe minimum temperature for ground meat.

How do I know when the loose sausage is cooked?

Color alone is not a reliable safety check, especially once the meat is mixed with tomatoes. Check several of the larger crumbles with a food thermometer and confirm that the ground pork reaches 160°F (71°C). If the reading is lower, continue cooking and check again. Break the meat into manageable pieces so it cooks evenly rather than leaving a large, thick clump in the center of the pan.

Can I prepare the seasoned pork ahead?

You can mix the pork with the dry seasonings up to 1 day ahead and keep it covered in the refrigerator at 40°F (4°C) or colder. Prepare the vegetables separately and refrigerate them in a covered container. Cook the mixture promptly after taking it out, and do not leave raw ground pork at room temperature for more than 2 hours. For the easiest workflow, measure the spices and chop the vegetables ahead while keeping them chilled.

Can I leave out the fennel?

Yes, though fennel is one of the flavors that makes the seasoning read as Italian-style sausage. If you dislike it, omit it or replace it with ½ teaspoon (1 g) ground coriander for a different, mildly citrusy flavor. Dried thyme or a little extra oregano can add herbal depth, but neither tastes exactly like fennel. Start with a small amount and taste the sauce before adding more.

Is this the same as sausage patties?

No. This recipe cooks the seasoned ground meat directly into a tomato-and-pepper skillet, so it stays in loose crumbles. To make patties, shape seasoned raw ground pork into even rounds and cook them separately in a lightly oiled skillet, checking that each reaches 160°F (71°C) with a thermometer. Patties take a different amount of time depending on their thickness, so use temperature rather than relying only on a set number of minutes.
