Step‑by‑Step Instructions for Creamy Italian Sausage Soup
Step 1: Melt the Butter
In a large soup pot, melt 2 tablespoons of butter over medium-high heat, watching for it to foam slightly. This will create a rich, flavorful base for your Creamy Italian Sausage Soup. Make sure to tilt the pot occasionally so the butter coats the bottom evenly, and let it heat for about a minute until fragrant.
Step 2: Sauté the Aromatics and Sausage
Add 1 chopped onion and 3 minced garlic cloves to the pot, stirring frequently. Cook for about 4–5 minutes, or until the onion turns translucent. Next, crumble in 1 pound of ground Italian sausage, cooking until it’s nicely browned and no longer pink, which should take around 6–8 minutes. This step builds the core flavors of the soup.
Step 3: Add Broth and Tomatoes
Once the sausage is browned, pour in 4 cups of chicken bone broth and add a 14-ounce can of fire-roasted tomatoes. Stir everything together well. Then, dollop in 8 ounces of cream cheese and stir until fully melted and incorporated into the broth, creating a creamy, luxurious texture. This should take around 3–5 minutes.
Step 4: Incorporate the Vegetables and Spices
Next, mix in 1 diced zucchini, 1 teaspoon of dried basil, 1 teaspoon of oregano, and freshly cracked black pepper to taste. Bring the mixture to a gentle boil, then reduce the heat to low. Simmer uncovered for 15–20 minutes, letting the zucchini soften while flavors meld, which will create that comforting essence of your Creamy Italian Sausage Soup.
Step 5: Add the Spinach
After the soup has simmered and the zucchini is tender, stir in 4 cups of baby spinach. Cook for about 3 minutes, or just until the spinach wilts down. This adds a pop of color and nutrition to your soup, making it not only delicious but visually appealing.
Step 6: Serve with Parmesan
Ladle the Creamy Italian Sausage Soup into bowls and top each serving with a generous sprinkle of shredded Parmesan cheese. Allow the cheese to melt slightly from the heat of the soup before serving. This final touch enhances the dish beautifully and brings all the flavors together.

How to Store and Freeze Creamy Italian Sausage Soup
Fridge: Store leftovers in an airtight container for up to 3 days. Cool the soup before refrigerating to maintain freshness.
Freezer: If you’d like to keep it longer, freeze in a freezer-safe container for up to 2 months. Leave some space at the top for expansion as it freezes.
Reheating: When ready to enjoy, reheat on the stove over low heat, adding a splash of broth if it thickens too much during freezing.
Thawing: For best results, thaw in the fridge overnight before reheating to ensure even warming and maintain the creamy texture.

Creamy Italian Sausage Soup Recipe FAQs
How do I choose the right ground Italian sausage?
Absolutely! When selecting ground Italian sausage, look for one that is well-seasoned with herbs and spices for the best flavor in your Creamy Italian Sausage Soup. Check for a bright color without any grayish tints and avoid packages that have dark spots or excessive liquid. If you prefer a healthier option, try lean turkey or chicken sausage, which still delivers delicious taste!
How should I store my leftover Creamy Italian Sausage Soup?
Very! Store your leftovers in an airtight container in the fridge for up to 3 days. Make sure to cool the soup to room temperature before sealing it, to keep it fresh. When reheating, do so on the stove over medium heat, adding a splash of broth if it thickens too much. This keeps the soup smooth and creamy, just like the first day!
Can I freeze Creamy Italian Sausage Soup?
Yes, indeed! To freeze the soup, pour it into a freezer-safe container, making sure to leave some space at the top for expansion, as liquids can swell when frozen. It will stay fresh for up to 2 months. To enjoy, simply thaw it overnight in the fridge and reheat gently on the stove, adding a little broth to restore its creaminess if necessary.
What if my soup is too thick?
If your Creamy Italian Sausage Soup ends up thicker than desired, don’t worry! Simply add a splash of broth or water while reheating, stirring until you reach your preferred consistency. It’s all about that creamy, comforting texture that brings warmth to your soul!
Are there any dietary considerations for this recipe?
Of course! This soup is quite flexible. For a dairy-free version, substitute cream cheese with coconut cream and use nutritional yeast instead of Parmesan cheese. Always check for gluten-free labels if that’s a concern, especially for your sausage and broth, ensuring a delicious meal all can enjoy. I recommend discussing ingredient swaps with family or friends if allergies are a concern!
What can I do with leftover ingredients?
Great question! If you have extra zucchini or spinach, toss them into a salad or stir-fry for a quick, healthy side dish. Unused herbs can be blended into a pesto or used to season chicken or fish, ensuring nothing goes to waste and keeping meals exciting!
