How to Make Creamy Parmesan Italian Sausage Soup

1. Brown the Italian sausage

Heat a large Dutch oven or heavy-bottomed soup pot over medium heat. Add the Italian sausage and cook, breaking it into small pieces with a wooden spoon.

Continue cooking until the sausage is browned and cooked through.

Don’t worry if small browned bits stick to the bottom of the pot. Those flavorful pieces will become part of the soup once the liquid is added.

If the sausage releases a large amount of excess fat, carefully drain some of it before continuing.

2. Sauté the onion and garlic

Add the chopped onion to the pot and cook until softened, about 4 to 5 minutes.

Add the minced garlic and cook for another 30 seconds to 1 minute, just until fragrant.

Be careful not to brown the garlic too much, as burnt garlic can give the entire soup a bitter flavor.

3. Add the broth and vegetables

Pour in the chicken broth and scrape the bottom of the pot with a wooden spoon to release any browned bits.

Add your chosen vegetables along with the Italian seasoning and red pepper flakes.

Bring the soup to a gentle simmer.

4. Simmer until the vegetables are tender

Let the soup simmer until the vegetables are cooked through.

The exact cooking time will depend on which vegetables you use. Potatoes and carrots will take longer than spinach or zucchini, so add quick-cooking vegetables toward the end.

Keep the soup at a gentle simmer rather than a vigorous boil. This helps the flavors develop while keeping the sausage tender.

5. Add the cream

Reduce the heat to low and slowly stir in the heavy cream.

Once the cream has been added, avoid boiling the soup aggressively. Gentle heat helps maintain a smooth, creamy consistency.

6. Stir in the Parmesan

Gradually add the freshly grated Parmesan, stirring continuously.

Give the cheese time to melt into the broth before adding more. The Parmesan will add saltiness, nuttiness, and body to the soup.

If the soup becomes thicker than you prefer, simply stir in a little additional chicken broth.

7. Taste and adjust

Now comes the important part: taste the soup.

Add black pepper, salt if necessary, and additional red pepper flakes if you want more heat.

You can also brighten the finished soup with a small squeeze of lemon juice. It won’t make the soup taste lemony; instead, it can help balance the richness of the cream and cheese.

Easy Variations

Once you’ve made the basic recipe, it’s easy to change it depending on your preferences.

Spicy Italian sausage soup

Use hot Italian sausage and increase the red pepper flakes. You can also add a pinch of crushed red pepper for extra heat.

Creamy sausage tortellini soup

Add refrigerated cheese tortellini toward the end of cooking. Simmer according to the package directions before finishing the soup with cream and Parmesan.

Low-carb creamy sausage soup

Skip potatoes and pasta and add extra leafy greens, mushrooms, zucchini, or cauliflower instead.

Lighter sausage soup

Use chicken or turkey Italian sausage and substitute half-and-half for heavy cream. The soup will still be creamy but somewhat lighter.

Sausage and kale soup

Replace spinach with chopped kale. Allow it to simmer a little longer so the leaves become tender.

Mushroom Parmesan sausage soup

Add sliced mushrooms along with the onion. Their earthy flavor pairs particularly well with Parmesan and Italian sausage.

FAQ’s

Can I use half-and-half instead of heavy cream?

Yes. Half-and-half is a good substitute if you’d like a lighter soup. The finished broth won’t be quite as rich, but it will still have a creamy texture.

Can I add pasta?

Absolutely. Tortellini, small shells, or another short pasta can turn this soup into an even heartier meal. Keep in mind that pasta absorbs liquid, so you may need to add extra broth.

Can I make this soup ahead of time?

Yes. It’s an excellent make-ahead meal. For the best texture, you can prepare the soup base in advance and add the cream and Parmesan when reheating.
