Ingredients

For this delicious Italian sausage orzo soup, you’ll need:

• 3 celery stalks (about 1 cup), diced
• 4 garlic cloves, minced
• 1 tablespoon Italian seasoning
• 1/2 teaspoon red pepper flakes (optional)
• 2 tablespoons tomato paste
• 1 can (14.5 oz/411g) diced tomatoes, undrained
• 6 cups (1.4 liters) chicken broth
• 1 cup (190g) dried orzo pasta
• 1 teaspoon salt, plus more to taste
• 1/2 teaspoon freshly ground black pepper

Pro Tips

When making this Irresistible One-Pot Italian Sausage Orzo Soup, these three techniques will elevate your results from good to exceptional:

First, take the time to properly brown the sausage until it develops a deep caramelization. This critical step creates foundational flavor compounds that infuse the entire soup. Break the sausage into small, bite-sized crumbles while browning—smaller pieces distribute more evenly throughout the soup and provide better texture in each spoonful.

Second, master the orzo cooking timing. Add the orzo only after your broth is actively simmering, and check it 2 minutes before the package directions suggest it should be done. The pasta will continue absorbing liquid after cooking, so serving it slightly al dente prevents it from becoming mushy. If preparing the soup ahead of time, consider cooking and storing the orzo separately, adding it just before serving.

Finally, create flavor layers through progressive seasoning. Season the sausage while browning, then taste and adjust again after adding the broth, and once more before serving. This builds a more complex flavor profile than only seasoning at the end. The final splash of fresh lemon juice just before serving is non-negotiable—it brightens the entire dish and balances the richness of the sausage and pasta.

Instructions

Step 1: Brown the Sausage

Heat a large Dutch oven or heavy-bottomed pot over medium-high heat. Add the Italian sausage, breaking it into small pieces with a wooden spoon. Cook for 7-8 minutes until browned and slightly crispy at the edges. The caramelization here creates essential flavor, so don’t rush this step. If there’s excessive fat (more than 1 tablespoon), drain some while leaving enough to cook the vegetables.

Step 2: Sauté the Aromatics

Add the diced onion, carrot, and celery to the pot with the browned sausage. Cook for 5 minutes until the vegetables begin to soften. Add the minced garlic, Italian seasoning, and red pepper flakes (if using), and cook for another 30 seconds until fragrant. Stir in the tomato paste and cook for 1-2 minutes, allowing it to slightly darken and coat the vegetables and sausage.

Step 3: Build the Soup Base

Pour in the diced tomatoes with their juices, scraping the bottom of the pot to release any browned bits. Add the chicken broth, salt, and pepper. Bring the mixture to a boil, then reduce to a simmer. Let it cook for 10 minutes to allow the flavors to meld and the vegetables to soften completely.

Step 4: Cook the Orzo

Add the orzo to the simmering broth and cook for 8-9 minutes, or until just tender. Stir occasionally to prevent the orzo from sticking to the bottom of the pot. The pasta will absorb some of the broth as it cooks, thickening the soup to a lovely consistency.

Step 5: Finish and Serve

Once the orzo is tender, stir in the fresh spinach and let it wilt for about 1 minute. Remove the pot from heat and stir in the fresh basil, grated Parmesan, and lemon juice. Taste and adjust seasonings if needed. Ladle the hot Italian sausage orzo soup into bowls, garnish with additional Parmesan cheese, and serve immediately with crusty bread for a complete meal.

Variations

This Irresistible One-Pot Italian Sausage Orzo Soup adapts beautifully to different preferences and dietary needs. For a lighter version, substitute the Italian sausage with turkey Italian sausage, which provides similar flavor with significantly less fat. The soup still maintains its hearty character while being more calorie-conscious.

For a vegetarian adaptation, omit the sausage completely and use vegetable broth instead of chicken broth. To replace the umami depth that sausage provides, add a tablespoon of soy sauce and increase the amount of mushrooms—cremini or shiitake varieties work particularly well. Consider adding a can of rinsed white beans for protein.

Seeking a creamier version? After the soup is fully cooked, stir in 1/2 cup of heavy cream or full-fat coconut milk for dairy-free needs. This creates a richer, silkier soup with a luxurious mouthfeel, perfect for special occasions or when you’re craving extra comfort. The creamy variation pairs particularly well with a rustic sourdough bread for dipping.

Storage and Serving

Store leftover Italian sausage orzo soup in an airtight container in the refrigerator for up to 4 days. Note that the orzo will continue absorbing liquid during storage, thickening the soup considerably. When reheating, add a splash of broth or water to restore the original consistency, and warm gently on the stovetop or in the microwave until heated through.

For freezing, it’s best to prepare the soup without the orzo, freezing the base for up to 3 months. When ready to serve, thaw completely, bring to a simmer, and add fresh orzo to cook just before serving.

Serve this comforting soup as a complete meal with a side of garlic bread for dipping into the flavorful broth. For a restaurant-style presentation, drizzle each serving with high-quality olive oil and add a fresh basil leaf. For a more substantial meal, pair with a simple arugula salad dressed with lemon vinaigrette to complement the robust flavors of the soup. The bright, peppery notes of the arugula provide a perfect counterpoint to the rich, savory nature of the one-pot sausage orzo soup.

FAQs

Can I make this soup ahead of time?
Yes! This Irresistible One-Pot Italian Sausage Orzo Soup actually improves with time as flavors meld. However, the orzo will continue absorbing liquid, so if making more than 2 hours ahead, consider cooking and storing the orzo separately, adding it when reheating.

Can I use different pasta instead of orzo?
Absolutely! Small pasta shapes like ditalini, stelline, or small shells work well. Adjust cooking time according to package directions, as larger pasta may take longer to cook than orzo.

Is this soup freezer-friendly?
It’s best to freeze this soup without the orzo and spinach. Prepare the base through Step 3, cool completely, and freeze for up to 3 months. When reheating, bring to a simmer, add orzo, and finish with fresh spinach.

Can I make this soup in a slow cooker?
Yes. Brown the sausage and sauté vegetables on the stovetop first, then transfer to a slow cooker with remaining ingredients except orzo, spinach, basil, Parmesan, and lemon juice. Cook on low for 6-7 hours, then add orzo and cook until tender (about 20-30 minutes). Stir in remaining ingredients before serving.

What can I substitute for spinach?
Kale, Swiss chard, or escarole make excellent substitutes. Kale and chard require slightly longer cooking times (3-4 minutes instead of 1), while escarole will wilt similarly to spinach.
