Sausage Ragu Recipe for a Rich, Slow-Simmered Pasta Sauce

Sausage ragu is a hearty Italian-style pasta sauce made by slowly simmering browned sausage with tomatoes, aromatic vegetables, wine, and herbs. This version balances the sausage’s savory richness with a little acidity and a long, gentle simmer, making a generous sauce for pasta, polenta, or baked dishes.

Ingredients

1½ lb Italian sausage (680 g), sweet or hot, casings removed if using links
1 tbsp olive oil (15 ml), only if the sausage is lean or the pan is dry
1 medium yellow onion (about 1 cup / 150 g), finely diced
1 medium carrot (about ½ cup / 60 g), finely diced
1 celery rib (about ½ cup / 60 g), finely diced
3 garlic cloves (about 9 g), minced
2 tbsp tomato paste (30 g)
½ cup dry red wine (120 ml), or use broth and a small splash of red wine vinegar
1 can crushed tomatoes (28 oz / 794 g)
½ cup low-sodium chicken broth (120 ml), plus more as needed
1 tsp dried oregano (1 g)
1 bay leaf
½ tsp fine salt (3 g), plus more to taste
¼ tsp freshly ground black pepper (about 0.5 g), plus more to taste
1 lb rigatoni, pappardelle, or another pasta (454 g)
½ cup finely grated Parmesan (about 45 g), plus more for serving
2 tbsp chopped fresh parsley or basil (about 8 g), optional

Instructions

Prepare the ingredients. Dice the onion, carrot, and celery into small, even pieces so they soften at a similar pace. Mince the garlic and remove the sausage casings if needed. Set out the wine, tomatoes, broth, oregano, and bay leaf before you start cooking; the sauce comes together more smoothly when these are ready.
Brown the sausage. Set a heavy Dutch oven or wide saucepan over medium heat. Add the sausage, breaking it into several large chunks rather than crumbling it finely at first. Cook for about 10 minutes, turning the pieces and letting them develop browned spots. If the pan is dry and the sausage is lean, add the olive oil. Check the thickest piece with a food thermometer; the USDA FSIS safe minimum for ground meat is 160°F (71°C). Once it reaches that temperature, break the sausage into bite-size pieces with a wooden spoon. If a substantial amount of fat has collected, spoon off some, leaving roughly 1 tablespoon in the pan for the vegetables.
Soften the vegetables. Add the onion, carrot, and celery to the pan. Cook for about 8 minutes, stirring occasionally and scraping up browned bits. The vegetables should soften and the onion should look translucent, but they do not need to brown deeply. Stir in the garlic and cook for about 30 seconds, just until fragrant.
Cook the tomato paste and deglaze. Stir in the tomato paste and cook for 1 minute, coating the sausage and vegetables. Pour in the red wine and scrape the base of the pan to loosen any caramelized bits. Simmer for about 3 minutes, until the sharp smell of alcohol has faded and the liquid has reduced slightly. If you are not using wine, add the broth at this point with 1 teaspoon red wine vinegar for a gentle lift; the finished sauce will be a little less complex but still flavorful.
Simmer the ragu. Add the crushed tomatoes, chicken broth, oregano, bay leaf, salt, and pepper. Stir well, bring the sauce to a gentle bubble, then lower the heat. Partly cover the pot and simmer for 70 minutes, stirring every 10 to 15 minutes. Keep the heat low enough that only a few bubbles break the surface. If the sauce becomes thicker than you like before the time is up, add broth or water 2 tablespoons at a time. If it is still loose at the end, uncover the pot for the last 10 minutes of simmering.
Cook the pasta and finish the sauce. Near the end of the simmer, bring a large pot of water to a boil and salt it. Cook the pasta according to its package directions until just al dente; start checking a minute before the suggested time. Reserve 1 cup (240 ml) pasta water, then drain. Remove the bay leaf from the sauce and taste it for salt and pepper. Add the drained pasta to the sauce, along with the Parmesan and a splash of pasta water. Toss for 1 to 2 minutes, adding more pasta water a little at a time until the sauce clings to the noodles. Finish with parsley or basil, if using, and serve with extra Parmesan.

Tips

Choose sausage to set the flavor. Sweet Italian sausage gives a mellow, herby sauce; hot sausage brings noticeable chile heat. For a middle ground, use half of each. Sausage seasoning varies, so taste before adding extra salt, especially if your broth and Parmesan are salty.
Give the meat room to brown. A crowded pan steams sausage instead of browning it. If your pot is small, brown the sausage in two batches. Starting with larger chunks also makes it easier to check the temperature before breaking the meat into the sauce.
Keep the simmer gentle. A hard boil can make the sauce splatter and reduce too quickly before the vegetables have softened. Stir along the bottom of the pot every 10 to 15 minutes, and add a little water or broth if the sauce starts catching.
Adjust the texture at the end. The sauce should be thick enough to coat pasta, not so dense that it sits in clumps. Pasta water loosens it while helping it cling; plain warm water or broth works if you forgot to reserve some, though it will not add the same starchy body.

Serving Suggestions

Rigatoni is a particularly good match because its ridges and hollow centers hold pieces of sausage and sauce. Pappardelle, tagliatelle, and wide egg noodles are also good choices, while short shapes such as shells or fusilli make an easy-to-eat bowl. If you prefer a different pasta, choose a sturdy shape that can stand up to a thick meat sauce. Cook it just to al dente and finish it in the sauce rather than serving the two separately; that brief toss helps the sauce coat the pasta evenly.

For a meal with a little contrast, serve the ragu with a simple green salad dressed with olive oil and vinegar, or with sautéed greens such as broccoli rabe, kale, or spinach. Warm crusty bread is useful for any sauce left at the bottom of the bowl. Offer extra grated Parmesan at the table, but taste the dish first because the cheese adds salt as well as a savory finish. A spoonful of chopped parsley or basil adds freshness; it is optional, not necessary for the sauce to taste complete.

The sauce also works beyond pasta night. Spoon it over soft polenta, use it as a layer in a baked pasta dish, or serve it with roasted vegetables. If serving the ragu separately from the pasta, keep the pasta and sauce in separate bowls until serving so the noodles do not absorb too much liquid while they wait.

Variations

Make it spicier or milder: Use hot Italian sausage for a more peppery sauce, or choose sweet sausage for a gentler version. You can also use a pinch of red pepper flakes with sweet sausage, adding them with the garlic. Start small; the long simmer concentrates the flavor.

Use a different sausage: Mild pork sausage, chicken sausage, or turkey sausage can stand in for Italian sausage. Choose a seasoned variety if possible, since plain sausage may need extra fennel, oregano, salt, and pepper. Chicken or turkey versions may be leaner, so add the olive oil if needed and avoid cooking them over high heat, which can make the meat dry.

Make it without wine: Replace the wine with the same amount of broth and stir in 1 teaspoon red wine vinegar. The vinegar is a practical substitute for the wine’s acidity, though it will not provide the same layered flavor. Avoid adding a large splash of vinegar; a little is enough to brighten the tomatoes.

Add more vegetables: Finely diced mushrooms can be cooked with the onion, carrot, and celery for a deeper, earthier flavor. Chopped fennel is another natural partner for Italian sausage. Keep additions to about 1 cup (100 g) total so the sauce remains rich and concentrated rather than turning into a vegetable-heavy stew.

Make a smoother sauce: Break the browned sausage into smaller pieces and dice the vegetables very finely. For an especially smooth tomato base, blend the crushed tomatoes before adding them, but do not blend the finished sauce unless you want to lose the texture of the sausage.

Storage and Reheating

Refrigerate leftover ragu within 2 hours of cooking in a shallow, covered container. The sauce keeps for 3 to 4 days in the refrigerator. If you have already mixed it with pasta, store the leftovers together, though the noodles will absorb some sauce as they sit. For the best texture, store sauce and pasta separately when you know you will have leftovers.

To freeze, cool the sauce promptly, portion it into airtight freezer-safe containers, and freeze for up to 3 months for best quality. Leave a little room at the top of each container for expansion. Thaw it overnight in the refrigerator, or warm it from frozen over low heat with a splash of water or broth, stirring as it loosens. Do not thaw it on the counter.

Reheat sauce gently in a covered saucepan over medium-low heat, stirring occasionally and adding a spoonful of water or broth if it has thickened. Reheat leftovers to 165°F (74°C), checking with a food thermometer. For a microwave, use a covered microwave-safe dish, stir at intervals, and check the temperature in more than one spot. Reheat only the portion you plan to eat.

Frequently Asked Questions

Can I make sausage ragu ahead of time?
Yes. The sauce can be made up to 3 to 4 days ahead and refrigerated, or frozen for up to 3 months for best quality. Let it cool promptly and refrigerate within 2 hours. Reheat it gently, adding a little water or broth if it has thickened, and cook the pasta shortly before serving for the best texture.

Do I need to remove sausage casings?
If you are using sausage links and want a sauce with crumbled meat, slit the casings and squeeze the sausage into the pan before browning. Some cooks leave links whole and slice them after cooking, but that gives the finished sauce larger sausage pieces. Bulk Italian sausage is ready to use without any casing to remove.

Can I make the ragu in a slow cooker?
For the best flavor, brown the sausage and soften the vegetables in a skillet first, then transfer them to the slow cooker with the remaining sauce ingredients. Cook on low until the vegetables are tender and the flavors have melded, usually about 6 to 8 hours, following your appliance’s instructions. Slow cookers vary, so check that the sausage reaches 160°F (71°C) and avoid adding too much broth; very little liquid evaporates in a covered slow cooker.

Why is my sausage ragu greasy?
Some sausage releases more fat than others. After browning, spoon off excess fat before adding the vegetables, leaving about 1 tablespoon to cook them. If the finished sauce still looks oily, tilt the pot and skim the oil from the surface with a spoon. Using a leaner sausage can help, but it may need a little olive oil to brown well.

What can I use instead of crushed tomatoes?
Whole peeled canned tomatoes work well: crush them by hand or with a spoon before adding them. Diced tomatoes can also be used, but they may leave a chunkier sauce. Passata makes a smoother sauce; if using it, start with the stated amount and check the consistency near the end, adding a little broth only if needed.

Can I cook the pasta directly in the ragu?
It is more reliable to boil the pasta separately. Pasta absorbs a considerable amount of liquid, and the amount varies by shape, so cooking it directly in the sauce can leave the ragu too thick or unevenly cooked. Finishing drained pasta in the sauce with reserved pasta water gives you control over both the noodle texture and the final consistency.
