This sausage ragu is a slow-simmered Italian meat sauce made with caramelized soffritto, browned Italian sausage, crushed tomatoes, beef broth, and a small bouquet of fresh herbs. I add Parmesan and a splash of heavy cream at the end, and the whole thing gets tossed with hot pasta. Make it on the stovetop, in an Instant Pot, or in a Slow Cooker.
Why This Sausage Ragu Beats Any Jarred Sauce
I make a lot of quick pasta. My 30-minute Italian sausage spaghetti and one-pot creamy sausage rigatoni both get dinner done in half an hour. But some pasta sauces simply require more time to get the flavor they deserve.
Here's the thing about this ragu: the prep is only 15 minutes. After that, the stove (or crockpot) does the work, and most of the cooking time is hands-off. The sauce simmers gently until it turns thick, dark, and clingy, and the sausage practically melts into it.
And yes, a slow cooker is perfect for Italian sausage ragu. That long, low simmer is what gives this pasta sauce its incredibly deep flavor. Just know that a covered slow cooker doesn't reduce the way an open pot does, so leave the lid cracked for the last hour if you want a thicker sauce.
But there is one step you should not skip, and that's cooking the veggies at the beginning. I know it's tempting to hurry it along. Don't. If you only soften the veggies, you will not have even close to the same flavor in the end.
You also get to decide how spicy this is. I use a spicy Italian sausage when I want a spicier pasta, and a mild Italian sausage when I want a sweeter one. Both are delicious - it just depends on your mood.
Recipe Highlights
- The sausage does the seasoning for you: it's the meat and the seasoning, since it's already packed with fennel, garlic, and herbs.
- Low and slow is the whole point: Ninety minutes to two hours in the pot is what turns a decent tomato sauce into a ragu. The tomatoes lose their raw edge, the sausage goes tender, and everything melts together, giving the sausage ragu its deep color.
- Almost entirely hands-off: After the first 25 minutes of chopping and browning, you stir every 20-30 minutes, and that's it. Or even better, transfer sausage ragu into a crockpot and let it simmer for hours. Perfect for a lazy Sunday or a make-ahead weeknight dinner.
- The cream and Parmesan: Half a cup of heavy cream at the end balances out the acidity and gives the sauce that silky, restaurant-style body.
- It feeds a crowd and freezes beautifully: This makes enough sauce for 6 generous servings, and the leftovers are even better on day two. Serve it with a loaf of my homemade garlic bread, and you've got a full Sunday dinner.
Ragù vs. Bolognese: What's the Difference?
Even though people use the words interchangeably, they're not quite the same.
- Ragù is the broad Italian term for any slow-simmered meat sauce with many variations across Italy.
- Bolognese, or ragù alla bolognese, is one specific style from Bologna, traditionally made with a mix of ground meats, white wine, and milk, with very little tomato.
- My version is tomato-forward like a Neapolitan-style ragù, but it borrows the soffritto and the finishing splash of cream from the Bologna tradition. My recipe uses Italian sausage instead of beef and pancetta. The result is richer than a marinara and lighter than a classic Bolognese. It's the perfect sauce for a big bowl of comforting pasta!
A Few Notes About Ingredients
1) Choosing Your Sausage
- Spicy or mild is your call. Use a spicy Italian sausage for a spicier pasta, or a mild Italian sausage for a sweeter pasta.
- Using leaner sausage? Simmer it for less time. If you choose to use a sausage that is lower in fat than pork, like a chicken or beef sausage, reduce the simmering time by about 20 to 30 minutes. If you don't, the meat will turn out tough and dry.
- Can't find ground sausage? Use links instead. Just remove the casings first and break the sausage up in the pan.
2) The Best Pasta for Sausage Ragu
- My favorite is rigatoni. Ragu is traditionally served with a wide noodle such as pappardelle, but I think a large tube-shaped pasta like rigatoni is my favorite. The tubes trap some of the meat and veggies inside.
- Pappardelle is the classic pick. If you want to keep it traditional, go with a wide noodle.
- Choose a hearty pasta. I don't recommend something thin or tiny like angel hair, spaghetti, or ditalini. The sauce is too chunky and rich for them.
How to Make Sausage Ragu (Step-by-Step Photos)
This is a recipe overview. Scroll down to find the complete instructions + ingredient amounts in the recipe card below.
- Caramelize the vegetables: Cook the onion, carrots, and celery in olive oil over just-below-medium heat for 15-20 minutes, until browned and nearly caramelized.
- Brown the sausage: Add the sausage and chili flakes, breaking up the meat as it cooks. Drain the grease.
- Cook the garlic and tomato paste: Stir both in and cook 1-2 minutes until the paste darkens.
- Deglaze: Add the water and scrape the bottom of the pot with a wooden spoon to lift all the browned fond.
- Make the sauce: Add the crushed tomatoes, beef broth, brown sugar, herbs, salt, and pepper. Stir, bring to a simmer, then lower the heat to a gentle bubble.
- Simmer low and slow: 90-120 minutes, stirring every 20-30 minutes. The sauce will darken, thicken, and reduce.
- Cook the pasta: About 20-25 minutes before the sauce is done, boil the pasta to al dente in well-salted water. Reserve 1 cup of pasta water before draining.
- Finish and toss: Remove the herb sprigs, stir in the Parmesan and cream, then add the hot drained pasta straight to the sauce and toss. Loosen with pasta water as needed.
Can I make this dairy-free and gluten-free?
- DAIRY-FREE: Skip the Parmesan and swap the heavy cream for full-fat canned coconut milk or an unsweetened plant cream. The sauce will still be full-bodied from all that reducing. If you want a no-dairy pasta night from the start, my Italian sausage pasta with spinach, artichokes, and sun-dried tomatoes is made entirely without cream or cheese.
- GLUTEN-FREE: Use gluten-free rigatoni or any other similar shortcut pasta labeled gluten-free.
What should I serve with sausage ragu?
Bread, first and foremost: my garlic butter dinner rolls or a warm loaf of homemade garlic bread for wiping the bowl clean. A simple green salad on the side is all you need after that. I also recommend serving sausage ragu with my strawberry spinach salad, Italian-inspired tomato cucumber avocado salad with mozzarella and basil pesto, or an absolute family-favorite apple spinach salad!
Slow-Simmered Sausage Ragu Pasta
Ingredients
Ragù Sauce
- 2 tablespoons olive oil
- 1 large yellow onion diced (about 1½ cups)
- 3 large carrots chopped (about 1½ cups)
- 2 stalks celery chopped (about ¾ cup)
- 1½ pounds Italian sausage pork
- ½ teaspoon red chili flakes
- 5 cloves garlic minced
- 6 oz tomato paste (1 can)
- ½ cup water
- 28 oz crushed tomatoes (1 can)
- 2 cups low-sodium beef broth
- 1 teaspoon brown sugar
- 3 sprigs fresh thyme
- 2 sprigs fresh rosemary
- 2 tablespoons fresh basil chopped
- 1 tablespoon fresh oregano chopped
- ½ teaspoon salt plus more to taste
- ¼ teaspoon coarse ground pepper
- ⅔ cup Parmesan cheese freshly shredded
- ½ cup heavy cream
- 16 oz pasta
- Parmesan and basil freshly shredded & chopped, for garnish
Instructions
- Caramelize the vegetables: In a tall skillet or large pot, heat the olive oil over just below medium heat. Add the onion, carrots, and celery and cook for about 15-20 minutes. You want the vegetables browned and nearly caramelized - this adds so much flavor to the ragu.
- Brown the sausage: Add the Italian sausage and red chili flakes. Cook until the sausage has browned, breaking it up as you cook. Drain the grease.
- Add the garlic and tomato paste and cook for about 1-2 minutes.
- Deglaze: Pour in the water and scrape the bottom of the pot with a wooden spoon to lift all the browned fond. If you use a non-stick pan, you may not have anything to scrape off.
- Simmer: Add the crushed tomatoes, beef broth, brown sugar, thyme, rosemary, basil, oregano, salt, and pepper. Stir to combine. Bring to a simmer, then reduce the heat to keep a gentle simmer. Simmer for 90-120 minutes, stirring every 20-30 minutes.
- Cook the pasta: About 20-25 minutes before the sauce is done, cook the pasta to al dente in a large pot of salted boiling water.
- Finish the sauce: While the pasta cooks, remove the herb sprigs, then add the Parmesan and heavy cream to the sauce and stir to combine.
- Combine: When the pasta is done, ladle about 1 cup of pasta water into a bowl and set it aside. Strain the pasta and immediately add it to the sauce, tossing to combine. If the sauce is too thick, add a splash of pasta water until you reach the right consistency.
- Serve warm with a sprinkle of fresh Parmesan and chopped basil.
Notes
- Cook the pasta to al dente and finish it in the sauce. Don't rinse it, don't let it sit in the colander, and always save a cup of that starchy pasta water. Tossing hot pasta directly into the ragu with a splash of the water is what makes the sauce cling to every piece instead of sitting on top of it.
- Don't rush the soffritto. Those first 15-20 minutes of browning the onion, carrots, and celery are where the depth of this sauce comes from. Pale vegetables make a flat ragu.
- Save your pasta water. The sauce thickens as it cools, so keep that reserved cup nearby to loosen it, at the table and again with leftovers.
- Use mild, sweet, or hot Italian sausage. If you go with hot sausage, I'd cut the red chili flakes back to ¼ teaspoon.
- Taste before you salt. Between the sausage, the beef broth, and the Parmesan, this sauce picks up a lot of salt on its own. Season at the very end.
Slow Cooker Instructions
You can let this sauce cook in a slow cooker when you get to the simmering section of the recipe. Here's how I do it:- Transfer the sauce to a slow cooker and set it to low for 6 to 8 hours.
- About an hour before you want to serve, add the heavy cream and the Parmesan cheese.
- Stir every 15 minutes until the cheese is melted and the sauce is combined nicely.
- Cook the pasta and finish like written in the recipe.
Instant Pot Instructions
- Set the Instant Pot to Sauté. Cook the onion, carrots, and celery with olive oil for 8-10 minutes, until softened and lightly browned.
- Add the sausage and red pepper flakes and cook until browned, breaking up the meat; drain excess grease if needed. Add the garlic and tomato paste and cook for 1 minute.
- Add the water and scrape the bottom of the pot thoroughly to prevent a burn warning. Stir in the crushed tomatoes, beef broth, brown sugar, herbs, salt, and pepper.
- Cook on High Pressure for 20 minutes, followed by a 10-minute natural release, then release the remaining pressure.
- Remove the herb sprigs and stir in the Parmesan and heavy cream. Toss with separately cooked pasta, adding a little reserved pasta water if needed to thin the sauce.
Make Ahead, Storage, and Freezing
- Store leftovers in the fridge for up to 4 days in an airtight container. Store the sauce separately from the pasta if you can.
- Make it ahead. The sauce is even better the next day. Simmer it a day early, refrigerate, and reheat gently while your pasta boils.
- Freezer: Freeze the sauce for up to 2 months, ideally before adding the cream and Parmesan. Thaw overnight in the fridge, reheat gently, then stir in the dairy.
