Ingredients You Need

Here is everything you need for a big pot of Italian Sausage Pasta Soup Recipe that feeds about 6 people.

Sausage and aromatics

1 pound Italian sausage, casings removed
- Use mild Italian sausage for kids or spice-sensitive folks.
- Use hot Italian sausage if you like more heat.
- Pork sausage gives the richest flavor, but chicken or turkey Italian sausage also works well.
1 tablespoon olive oil (only if your sausage looks very lean)
1 large yellow onion, diced
3 cloves garlic, minced
2 medium carrots, diced
2 celery stalks, diced

Broth, tomatoes, and pasta

6 cups low sodium chicken broth
- Use a good quality boxed broth; I like Kitchen Basics or Pacific for solid flavor.
- If you only have regular broth, reduce added salt and taste as you go.
1 can (14.5 ounces) diced tomatoes, with juices
- Fire roasted tomatoes add a deeper flavor if you have them.
1 can (8 ounces) tomato sauce
1 cup small pasta
- Ditalini, small shells, elbow macaroni, or orecchiette all work great.
- Use gluten free pasta if needed and cook it slightly under so it holds texture.

Veggies and flavor boosters

1 small zucchini, diced (optional but tasty)
1 cup baby spinach or chopped kale, packed
1 teaspoon Italian seasoning
1 teaspoon dried basil (or extra Italian seasoning if you prefer)
1 teaspoon kosher salt, plus more to taste
½ teaspoon black pepper
¼ to ½ teaspoon crushed red pepper flakes (optional, for extra heat)

Creamy twist (optional but highly recommended)

½ cup heavy cream or half and half
- You can skip this for a lighter soup or use evaporated milk from the pantry.

Toppings

Freshly grated Parmesan cheese
Chopped fresh parsley or basil
Extra red pepper flakes

Equipment list

Large heavy pot or Dutch oven (5 to 6 quart size)
Wooden spoon or spatula
Cutting board and sharp knife
Ladle
Measuring cups and spoons

Tips & Mistakes

Brown the sausage well so it builds flavor on the bottom of the pot instead of steaming in its own juices.
Drain excess fat if the sausage releases a lot, or keep a little if you want a richer broth.
Chop veggies small so they soften quickly and match the size of the pasta.
Salt in layers while you cook instead of dumping it all at the end.
Add pasta near the end of cooking so it stays al dente and does not turn mushy.
Cook pasta directly in the soup for more flavor, but add extra broth if it thickens too much.
Use pre-chopped mirepoix from the store when you feel short on time or energy.
Stir the bottom of the pot often after you add tomatoes so nothing sticks and scorches.
Add cream off the heat or on very low so it does not curdle.
Taste before serving and adjust salt, pepper, and red pepper flakes so the flavor pops.

How to Make Italian Sausage Pasta Soup Recipe

Step 1: Brown the sausage

Set a large pot over medium high heat and let it heat for a minute. Add the sausage and break it up with a wooden spoon into small crumbles. Cook until the sausage turns browned and cooked through and little browned bits form on the bottom of the pot, about 6 to 8 minutes.

If the sausage releases a lot of fat, spoon off some, but leave about 1 tablespoon in the pot. If the sausage looks very lean and starts to stick, add a drizzle of olive oil.

Step 2: Sauté the aromatics

Add the diced onion, carrots, and celery to the pot with the sausage. Stir and cook until the onion turns translucent and the veggies start to soften, about 5 minutes. Add the minced garlic and cook 30 to 60 seconds, just until it smells fragrant and toasty.

Sprinkle in the Italian seasoning, dried basil, salt, pepper, and crushed red pepper flakes. Stir so the spices coat the sausage and veggies and toast slightly.

Step 3: Build the broth

Pour in the chicken broth, diced tomatoes with their juices, and tomato sauce. Stir well and scrape the bottom of the pot to lift up all the browned bits into the liquid. Add the diced zucchini if you use it.

Bring the soup up to a gentle boil, then lower the heat to a steady simmer. Let it bubble for about 10 minutes so the flavors blend and the veggies soften more.

Step 4: Add the pasta

Stir in the small pasta. Keep the soup at a steady simmer and cook until the pasta turns al dente, usually 8 to 10 minutes, depending on the shape. Stir often so the pasta does not stick to the bottom.

If the soup thickens more than you like as the pasta cooks, add another ½ to 1 cup of broth or water. Taste a piece of pasta to check for doneness rather than trusting the box time.

Step 5: Add greens and cream

Stir in the spinach or kale and cook just until the greens wilt and turn tender, about 2 to 3 minutes. Turn the heat to low. Pour in the heavy cream or half and half, then stir until the broth looks silky and slightly creamy.

Taste and adjust seasoning with more salt and pepper if needed. The sausage and broth both contain salt, so check before you add more.

Step 6: Serve

Ladle the Italian Sausage Pasta Soup Recipe into bowls while hot. Top with a generous shower of grated Parmesan and a sprinkle of fresh parsley or basil. Add extra red pepper flakes for anyone who likes more kick.

Variations I've Tried

I swap the pasta for small cheese tortellini when I want a heartier, almost stew-like bowl. I cook the tortellini directly in the soup and shorten the simmer time so it stays tender.

I use chicken or turkey Italian sausage when I want a lighter version, and it still tastes rich once the broth and tomatoes cook together. I also add white beans for extra protein and fiber, which turns the soup into a very filling one pot meal.

I sometimes skip the cream and stir in a spoonful of pesto at the end, which gives the soup a bright, herby finish. I also toss in extra veggies like bell peppers, mushrooms, or chopped kale stems when I need to clear out the fridge.

How to Serve Italian Sausage Pasta Soup Recipe

Serve Italian Sausage Pasta Soup Recipe hot in wide bowls so the pasta, sausage, and veggies spread out nicely. Add a big spoonful of grated Parmesan on top and a sprinkle of fresh herbs for color. Pair it with crusty bread, garlic bread, or simple toast for dunking and scooping.

You can also serve it with a crisp green salad or sliced cucumbers and cherry tomatoes on the side. Kids usually love this soup, especially if you use mild sausage and smaller pasta shapes.

How to store

Fridge: Cool the soup to room temperature, then store it in airtight containers in the refrigerator for up to 4 days.
Freezer (with pasta): The pasta softens in the freezer, but you can still freeze leftovers for up to 2 months in freezer safe containers.
Freezer (pasta on the side): If you plan ahead, store the soup without pasta in the freezer for up to 3 months, then cook fresh pasta and add it when you reheat.
Best reheating method: Reheat on the stove over medium heat, stirring often, and add a splash of broth or water if it thickens. Warm single portions in the microwave in 60 second bursts, stirring between each, until hot.
