Ingredients You’ll Need

Sausage, Pasta, and Broth

1 pound Italian sausage
- Use mild or hot, chicken or turkey sausage if you want a lighter option.
- Remove casings if you use links.
1 cup small pasta
- Ditalini, small shells, elbow macaroni, or orecchiette all work.
- Use whole wheat pasta if you like extra fiber.
6 cups low sodium chicken broth
- Use a good quality boxed broth; I like Kitchen Basics or Pacific.
- Add 1 extra cup if you prefer a thinner soup.

Vegetables and Aromatics

1 medium yellow onion, diced
2 medium carrots, diced
2 celery stalks, diced
3 to 4 garlic cloves, minced
1 red bell pepper, diced (optional but adds sweetness and color)
1 to 2 cups fresh baby spinach or chopped kale
- Use frozen spinach in a pinch; thaw and squeeze out extra water.

Tomatoes and Seasoning

1 can (14.5 ounces) diced tomatoes
- Fire roasted tomatoes add a nice smoky depth.
2 tablespoons tomato paste
1 teaspoon dried Italian seasoning
1 teaspoon dried basil (optional if your Italian seasoning already includes it)
1 teaspoon kosher salt, plus more to taste
½ teaspoon black pepper
¼ to ½ teaspoon red pepper flakes (optional, for heat)

Creamy Finish

½ to ¾ cup heavy cream or half and half
- Use half and half for a lighter version or skip it for a tomato broth style soup.
½ cup grated Parmesan cheese, plus extra for serving
- Use real Parmigiano Reggiano if possible; it melts smoother and tastes richer.

Pantry Shortcuts

Use frozen mirepoix mix (onion, carrot, celery) to skip chopping.
Use jarred minced garlic if you feel tired or short on time.
Use pre shredded Parmesan from the refrigerated section, not the shelf stable green can.

Equipment List

Large heavy pot or Dutch oven (at least 5 to 6 quarts)
Wooden spoon or spatula
Chef’s knife and cutting board
Ladle
Measuring cups and spoons

Tips & Tricks

Brown the sausage well so it develops deep flavor and little crispy bits on the bottom of the pot.
Drain extra fat if your sausage releases a lot, but keep 1 to 2 tablespoons for flavor.
Chop veggies into similar sizes so they cook evenly and stay tender, not mushy.
Add garlic after the veggies soften so it does not burn and turn bitter.
Toast tomato paste in the pot for 1 to 2 minutes so it tastes richer and less sharp.
Add pasta near the end and cook it just to al dente so it stays firm in the broth.
If you plan to store leftovers, cook the pasta separately and add it to each bowl so it does not soak up all the broth.
Taste the soup before serving and adjust salt, pepper, and red pepper flakes at the end.
Stir in cream off the heat or on low so it does not curdle.
Add spinach or kale right at the end so it stays bright and fresh.

How to Make Italian Sausage Pasta Soup Recipe

Step 1: Brown the Sausage

Set a large pot over medium high heat.
Add the Italian sausage and break it into small crumbles with a wooden spoon.
Cook 6 to 8 minutes until the sausage browns and no pink remains.
Scoop out some excess fat if the pot looks very greasy, but leave a thin layer for flavor.

Step 2: Sauté the Vegetables

Add diced onion, carrot, and celery to the pot with the sausage.
Stir and cook 5 to 6 minutes until the veggies soften and the onion turns translucent.
Add the diced red bell pepper if you use it and cook 2 minutes more.
Add minced garlic and cook about 30 seconds until it smells fragrant.

Step 3: Build the Tomato Base

Stir in the tomato paste and coat the sausage and veggies.
Cook 1 to 2 minutes, stirring, so the tomato paste darkens slightly and sweetens.
Add the can of diced tomatoes with their juices.
Sprinkle in Italian seasoning, dried basil, salt, black pepper, and red pepper flakes.

Step 4: Add Broth and Simmer

Pour in the chicken broth and stir well, scraping the bottom of the pot to release browned bits.
Bring the soup up to a gentle boil.
Lower the heat to a steady simmer and cook 10 to 15 minutes so the flavors blend and the veggies turn tender.
Taste the broth and adjust seasoning if it needs more salt or spice.

Step 5: Cook the Pasta

Stir in the small pasta.
Simmer 8 to 10 minutes, stirring occasionally so the pasta does not stick to the bottom.
Check a piece of pasta and stop cooking when it reaches al dente, since it will soften a bit more in the hot soup.
If the soup looks too thick, add a splash of extra broth or water.

Step 6: Add Greens and Creamy Finish

Stir in the spinach or kale.
Cook 1 to 2 minutes until the greens wilt and turn bright.
Lower the heat to low and pour in the heavy cream or half and half.
Stir in grated Parmesan cheese until it melts and the soup turns slightly creamy and glossy.

Step 7: Final Taste and Serve

Taste the Italian Sausage Pasta Soup Recipe again and adjust salt, pepper, or red pepper flakes.
Ladle the soup into bowls.
Top with extra Parmesan and a sprinkle of fresh basil or parsley if you have it.
Serve hot with bread or a simple side so nobody leaves the table hungry.

What to Serve with it?

This Italian Sausage Pasta Soup Recipe pairs nicely with a simple green salad with crisp lettuce, cucumbers, and a light vinaigrette. Warm crusty bread, garlic breadsticks, or focaccia taste perfect for dunking into the tomato broth. Add a side of roasted vegetables like broccoli, green beans, or zucchini for extra color and nutrients. If you want something fun, serve a small plate of fresh fruit or a simple tomato and cucumber salad on the side.

Storage Options

Cool the soup to room temperature, then store it in airtight containers in the fridge for 3 to 4 days.
If you plan to store leftovers, cook pasta separately and add it to each bowl so it does not soak up all the broth in the fridge.
Freeze the soup without pasta in freezer safe containers or bags for up to 2 to 3 months.
Reheat on the stove over medium heat, add a splash of broth or water if it thickens, and stir in freshly cooked pasta right before serving.
Reheat single portions in the microwave in 1 minute bursts, stirring between each, until hot and steamy.
