Ingredients

For this delicious Italian Sausage & Orzo Soup, gather:

• 1 pound (454g) Italian sausage, casings removed (sweet or hot, based on preference)

• 1 medium yellow onion, diced (about 1 cup)
• 3 carrots, peeled and diced (about 1 cup)
• 2 celery stalks, diced (about ½ cup)
• 4 garlic cloves, minced
• 1 teaspoon dried oregano
• 1 teaspoon dried basil
• ½ teaspoon red pepper flakes (adjust to taste)
• 6 cups (1.4 liters) chicken broth
• 1 can (14.5 oz/411g) diced tomatoes, undrained
• 1 cup (190g) orzo pasta, uncooked

Pro Tips

Creating truly exceptional Italian Sausage & Orzo Soup comes down to mastering three critical techniques. First, properly brown the sausage until it develops a deep caramelization. This step creates the foundation of flavor for your soup – resist the urge to rush this process! Allow the sausage to develop crispy edges and deep golden color before breaking it apart, which introduces complex, savory notes impossible to achieve otherwise.

Second, control the orzo cooking time carefully. Unlike other pasta soups where noodles can be added all at once, add the orzo in the last 8-10 minutes of cooking. This prevents the pasta from becoming overly soft and absorbing too much broth. For meal prep purposes, consider cooking and storing the orzo separately, adding it only when reheating individual portions.

Finally, layer your seasonings thoughtfully. Add dried herbs early in the cooking process to allow their flavors to bloom in the oil, but reserve fresh herbs for the final minutes. This two-stage seasoning approach creates dimension in your hearty Italian soup that distinguishes homemade quality from commercial versions. Taste and adjust seasonings just before serving, as flavors concentrate as the soup simmers.

Instructions

Step 1: Brown the Sausage

Heat olive oil in a large Dutch oven or heavy-bottomed pot over medium-high heat. Add the Italian sausage, breaking it into smaller chunks with a wooden spoon. Let it cook undisturbed for 2-3 minutes until the bottom develops a golden crust before stirring. Continue cooking for 5-7 minutes total until the sausage is well-browned and no pink remains. If excess fat accumulates, drain all but about 1 tablespoon from the pot.

Step 2: Sauté the Aromatics

Add the diced onions, carrots, and celery to the pot with the browned sausage. Cook for 4-5 minutes, stirring occasionally, until the vegetables begin to soften. Add the minced garlic, dried oregano, dried basil, and red pepper flakes. Stir continuously for 30-60 seconds until fragrant, being careful not to burn the garlic.

Step 3: Build the Soup Base

Pour in the chicken broth and diced tomatoes with their juice, using your spoon to scrape up any browned bits from the bottom of the pot. These caramelized bits contain concentrated flavor that will enrich your Italian Sausage & Orzo Soup. Bring the mixture to a boil, then reduce heat to maintain a gentle simmer. Season with salt and black pepper to taste.

Step 4: Add the Orzo

Once the soup is simmering, add the uncooked orzo pasta. Stir occasionally to prevent sticking. Cook for 8-10 minutes until the orzo is tender but still has a slight firmness (al dente). The pasta will continue to absorb liquid as the soup sits, so avoid overcooking.

Step 5: Finish and Serve

When the orzo is just tender, stir in the chopped spinach and let it wilt for about 1-2 minutes. Remove the pot from heat and stir in the grated Parmesan cheese and fresh parsley. Taste and adjust seasonings if needed. Serve your Italian Sausage & Orzo Soup immediately in warmed bowls, topped with additional Parmesan cheese if desired.

Variations

For a lighter version of this Italian Sausage & Orzo Soup, substitute turkey Italian sausage for traditional pork sausage. This simple swap cuts calories and fat while maintaining the classic flavor profile. The soup will still develop rich flavor, especially if you take time to properly brown the turkey sausage.

Create a creamy variation by adding ½ cup of heavy cream or full-fat coconut milk (for a dairy-free option) in the final 5 minutes of cooking. This transforms the tomato-based broth into a luscious, silky soup with additional richness that pairs beautifully with the savory sausage and orzo pasta soup.

For a vegetable-forward adaptation, double the spinach and add 1 cup of diced zucchini or yellow squash when you add the orzo. This increases the nutritional value while creating a more substantial garden-style soup. You can also substitute kale for spinach if you prefer a heartier green that holds its texture longer during cooking and reheating.

Storage and Serving

Store leftover Italian Sausage & Orzo Soup in airtight containers in the refrigerator for up to 4 days. The soup will thicken considerably as the orzo continues to absorb liquid. When reheating, add ¼ to ½ cup additional chicken broth or water to reach your desired consistency. Warm gently on the stovetop over medium-low heat or microwave in 1-minute intervals, stirring between each.

For freezing, prepare the soup without the orzo and freeze for up to 3 months. When ready to serve, thaw overnight in the refrigerator, bring to a simmer, and add fresh orzo, cooking until tender.

Serve this hearty Italian sausage soup with a side of crusty garlic bread for dipping into the flavorful broth. For a complete meal, pair with a simple arugula salad dressed with lemon vinaigrette and shaved Parmesan, creating a delightful contrast to the warm, savory soup. For an authentic Italian experience, offer small bowls of additional toppings like extra red pepper flakes, fresh basil chiffonade, and high-quality extra virgin olive oil for drizzling.

FAQs

Can I use a different pasta instead of orzo?
Yes! Small pasta shapes like ditalini, acini di pepe, or small shells work well in this Italian Sausage & Orzo Soup. Adjust cooking time based on package directions, as larger pasta may require additional minutes.

How do I prevent the orzo from absorbing too much broth?
If preparing ahead or planning leftovers, consider cooking the orzo separately and adding it to individual portions when serving. Alternatively, undercook the orzo slightly (2 minutes less than package directions) if you know the soup will be sitting for some time.

Can I make this soup vegetarian?
Absolutely. Substitute the Italian sausage with plant-based sausage alternatives or 2 cups of sliced mushrooms sautéed with 1 teaspoon of fennel seeds. Use vegetable broth instead of chicken broth for a fully vegetarian version.

My soup seems too thick. How can I adjust it?
The orzo will continue absorbing liquid, naturally thickening the soup. Simply add more chicken broth or water until you reach your desired consistency, then adjust seasonings as needed.

How can I increase the spice level?
For a spicier Italian Sausage & Orzo Soup, use hot Italian sausage instead of mild, double the red pepper flakes, or add a diced jalapeño with the other vegetables. You can also serve with crushed red pepper flakes on the side.
