Ingredients You Need

Main ingredients

1 pound Italian sausage, casings removed
- Use mild for family friendly soup, hot for extra kick, or a mix of both.
1 tablespoon olive oil, only if your sausage looks very lean
1 medium yellow onion, diced small
2 medium carrots, peeled and diced
2 celery stalks, diced
3 to 4 garlic cloves, minced
1 teaspoon kosher salt, plus more to taste
½ teaspoon black pepper
1 teaspoon dried Italian seasoning or a mix of dried basil and oregano
¼ teaspoon crushed red pepper flakes, optional for heat
2 tablespoons tomato paste
1 can (14.5 ounces) diced tomatoes, fire roasted if possible for extra flavor
6 cups low sodium chicken broth or stock
- Use a good quality boxed broth; I like Kitchen Basics or Pacific for rich flavor.
1 cup dried ditalini pasta
- You can swap small shells, elbow macaroni, or small orecchiette if needed.
1 Parmesan rind, optional but highly recommended for flavor

Creamy Parmesan finish

¾ cup finely grated Parmesan cheese, plus extra for serving
- Use real Parmigiano Reggiano if possible; it melts smoother and tastes nuttier.
½ to 1 cup half and half or heavy cream
- Half and half keeps it lighter, heavy cream makes it extra luxurious.

Fresh finish

2 cups baby spinach or chopped kale, loosely packed
2 tablespoons fresh parsley, chopped
Lemon wedges, optional for serving to brighten the flavors

Pantry shortcuts and substitutions

Use frozen mirepoix (onion, carrot, celery mix) to skip chopping.
Use jarred minced garlic if you feel tired or short on time.
Swap chicken broth with vegetable broth for a slightly lighter flavor.
Use pre shredded Parmesan from the refrigerated section if you cannot grate your own, but avoid the shelf stable green can since it clumps.

Equipment list

Large heavy pot or Dutch oven, at least 5 quarts
Wooden spoon or spatula
Chef’s knife and cutting board
Ladle
Measuring cups and spoons
Microplane or fine grater for Parmesan

Tips & Mistakes

Brown the sausage well so it develops browned bits on the bottom of the pot, since those bits give the broth deep flavor.
Drain excess fat if the sausage releases a lot, or the soup can taste greasy.
Dice the vegetables small and evenly so they soften at the same rate and feel pleasant in each spoonful.
Toast the tomato paste for 1 to 2 minutes so it tastes rich instead of metallic.
Add the ditalini near the end of cooking, or it can swell too much and soak up all the broth.
Cook the pasta just to al dente, since it continues to soften in the hot soup.
Stir in the cream and Parmesan off the heat or on very low heat so the dairy does not curdle.
Use freshly grated Parmesan so it melts smoothly and does not clump.
Taste and adjust salt at the end, since the sausage and Parmesan both add saltiness.
Store leftover pasta and soup separately if you plan ahead, so the pasta does not turn mushy.

How to Make Parmesan Italian Sausage Ditalini Soup Recipe

Step 1: Brown the sausage

Heat a large pot over medium high heat. Add the Italian sausage and break it into small crumbles with a spoon. Cook 6 to 8 minutes until the sausage browns and no pink remains.

If the sausage releases more than a tablespoon or two of fat, spoon some out so the soup does not taste heavy. Leave a thin layer of fat in the pot for flavor. Transfer the cooked sausage to a bowl and keep it nearby.

Step 2: Sauté the vegetables

Lower the heat to medium. If the pot looks dry, add the olive oil. Add the diced onion, carrots, and celery, then stir to coat in the fat.

Cook 5 to 7 minutes until the vegetables soften and the onion turns translucent around the edges. Add the garlic, salt, pepper, Italian seasoning, and red pepper flakes. Stir and cook 1 minute until the garlic smells fragrant.

Step 3: Build the tomato base

Add the tomato paste to the pot. Stir it into the vegetables and cook 1 to 2 minutes so it darkens slightly and tastes richer. Scrape the bottom of the pot to pick up any browned bits from the sausage.

Pour in the diced tomatoes with their juices. Stir everything together and let it bubble for 2 minutes so the flavors start to blend.

Step 4: Add broth and simmer

Return the browned sausage and any juices from the bowl to the pot. Pour in the chicken broth and stir well. Add the Parmesan rind if you have one.

Bring the soup to a gentle boil over medium high heat. Lower the heat to maintain a steady simmer and cook 15 minutes so the flavors deepen and the vegetables turn tender. Stir occasionally so nothing sticks.

Step 5: Cook the ditalini

Add the ditalini pasta to the simmering soup. Stir well so the pasta does not clump at the bottom. Cook 8 to 10 minutes, or until the pasta reaches al dente texture.

Taste a piece of pasta to check doneness. If you prefer a slightly thicker soup, let it simmer a couple more minutes so the starch from the pasta lightly thickens the broth. Remove the Parmesan rind and discard it.

Step 6: Add greens and Parmesan

Stir in the spinach or kale. Cook 2 to 3 minutes until the greens wilt and turn bright. Lower the heat to low or turn it off if the soup feels very hot and bubbly.

Add the grated Parmesan cheese in small handfuls while you stir. Let each handful melt before you add more so the cheese blends smoothly into the broth.

Step 7: Finish with cream and adjust seasoning

Pour in ½ cup of half and half or cream and stir. Taste the soup and add more cream if you want a richer, creamier texture. Taste for salt and pepper and adjust until the flavors pop.

If the soup feels too thick, add a splash of broth or water to loosen it. Stir in the chopped parsley. Squeeze a little lemon juice into your own bowl if you like a bright finish.

Variations I've Tried

Use turkey Italian sausage instead of pork for a lighter version that still tastes hearty. Swap the spinach with chopped kale and simmer it a few extra minutes for a slightly earthier flavor. Add a can of drained cannellini beans to boost protein and make the soup stretch further.

Use small gluten free pasta if you need a gluten free option, and cook it separately in salted water so it does not shed too much starch into the soup. Stir in a handful of shredded mozzarella or provolone right before serving if you want extra cheese pull. Add diced zucchini or bell pepper with the carrots and celery to sneak in more vegetables.

How to Serve Parmesan Italian Sausage Ditalini Soup Recipe

Serve this Parmesan Italian Sausage Ditalini Soup Recipe in warm bowls and top it with extra grated Parmesan and a sprinkle of parsley. Add a side of crusty bread, garlic toast, or simple buttered rolls to soak up the broth. Pair it with a crisp green salad or a basic Caesar style salad for a full meal. Kids usually love this one, since it feels like cheesy pasta in soup form.

How to store

Cool the soup to room temperature, then store it in airtight containers in the fridge for up to 4 days.
If possible, store extra cooked ditalini in a separate container and add it to each bowl when you reheat, so the pasta does not over soften.
Freeze the soup without the pasta for best texture, in freezer safe containers, for up to 3 months.
Reheat on the stove over medium heat, stirring often, and add a splash of broth or water if it thickens too much; you can also reheat individual bowls in the microwave in short bursts, stirring between each burst.
