Ingredients
- 5–6 uncased Italian sausages (about 1½–2 pounds)

- 1 large carrot, diced
- ½ onion, diced
- 1 large stalk celery, diced
- 1 tablespoon butter
- 1 teaspoon fennel

Recipe Tips
Mirepoix
The classic combination of onion, celery, and carrot creates the perfect foundation for this recipe. It builds depth of flavor that you simply won’t get from using onions alone. It also adds extra vegetables to the sauce without overpowering the classic Italian flavor.
Tomato Paste
The two tablespoons of tomato paste add another layer of richness and intensify the overall flavor of the sauce. You can make this recipe without it, but it will feel like something is missing. For the best flavor, let the tomato paste cook for about a minute before adding the passata.
Passata
I use passata instead of crushed tomatoes because it creates a smooth, silky sauce without any seeds or skins. It also gives the sauce a rich texture while reducing the amount of time it needs to simmer, making it perfect for a quick homemade pasta sauce.
Italian Sausage
Using uncased Italian sausage is one of the reasons this recipe comes together so easily. The sausage is already seasoned with herbs and spices, adding incredible flavor without needing a long list of extra ingredients. I prefer mild Italian sausage, but hot Italian sausage works just as well if you like a little heat.
How to This Make Italian Sausage Pasta Sauce Recipe
Step 1: Prepare Your Ingredients
Start by gathering all of your ingredients. Dice the onion, carrot, and celery, prepare your spices, and remove the Italian sausage from its casings if needed. Having everything ready before you start cooking makes the process much smoother.
Step 2: Build the Base
Heat a large pot over medium heat and add a little olive oil or butter. Add the diced onion, carrot, and celery, then sauté until the vegetables begin to soften and become fragrant.
Step 3: Brown the Sausage
Add the uncased Italian sausage to the pot with the mirepoix. Break it into small pieces with a wooden spoon and cook until it’s browned and no longer pink.
Step 4: Add the Tomatoes
Stir in the tomato paste and cook for about one minute to deepen its flavor. Then add the passata and balsamic vinegar, stirring everything together until well combined.
Step 5: Season the Sauce
Add the fennel, oregano, salt, pepper, and fresh basil. Stir well so the herbs and spices are evenly distributed throughout the sauce.
Step 6: Simmer
Pour in the water and bring the sauce to a gentle simmer. Let it cook uncovered for at least one hour, allowing the water to evaporate and the sauce to reduce until it becomes thick and rich. The sauce is ready when it coats the back of a spoon and most of the added water has reduced away.
Step 7: Cook the Pasta
As the sauce finishes simmering, cook your favourite pasta according to the package directions until al dente.
Step 8: Finish the Sauce
Once the sauce has finished reducing, stir in the butter. This gives the sauce a rich, silky finish and rounds out the flavors.
Step 9: Serve
Toss the sauce with your cooked pasta or spoon it over top. Finish with freshly grated parmesan and fresh basil before serving.
Pro Tips
Tomato Paste
Cook the tomato paste for about one minute before adding the passata to deepen its flavor.
Taste Test
Taste the sauce every 20 minutes as it simmers. You’ll notice the flavor becoming richer as it reduces.
Simmer Time
If you’d like even more depth of flavor, add a little more water and continue simmering.
Season
Adjust the seasonings to your taste. Bay leaves and dried basil also make great additions.

Freeze with Pasta
Allow the pasta and sauce to cool completely before portioning into freezer-safe containers. Freeze for 3–6 months.
Freeze the Sauce Only
I often freeze just the sauce in freezer bags or airtight containers. This makes it easy to cook fresh pasta later and have a homemade dinner on the table in minutes. The sauce keeps well for 3–6 months.
For the best results, thaw overnight in the refrigerator before reheating.
