Ingredients

• 2 celery stalks, diced (about ¾ cup)
• 4 garlic cloves, minced
• 1 tablespoon Italian seasoning
• ¼ teaspoon red pepper flakes (optional, for heat)
• 1 can (14.5 oz/411g) diced tomatoes
• 6 cups (1.4L) chicken broth
• 1 cup (200g) dry orzo pasta
• 4 cups (120g) fresh spinach (or kale)

Pro Tips

Achieving soup perfection with your Italian Sausage Orzo Soup comes down to mastering a few critical techniques. First, don’t rush the sausage browning process—take your time to develop those crispy, caramelized bits on the bottom of the pot. These browned pieces are flavor gold, creating depth in your soup that can’t be achieved any other way. When you deglaze the pot with a splash of broth, be sure to scrape all these bits up to incorporate them into your broth.

Second, be mindful of your orzo cooking time. Unlike hearty beans or root vegetables that can withstand long simmering, orzo can quickly go from perfectly al dente to mushy. Add the orzo about 10 minutes before you plan to serve the soup, and check it frequently. The pasta will continue to absorb liquid even after the heat is turned off, so consider cooking it just shy of your preferred tenderness.

Finally, season in layers rather than all at once. Add salt and pepper when sautéing the vegetables, again when adding the broth, and taste before serving to make final adjustments. This building of flavors creates a more complex and well-rounded sausage orzo soup that tastes like it’s been developing for hours.

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 apart with a wooden spoon into bite-sized chunks. Cook until nicely browned and slightly crispy on the edges, about 5-7 minutes. This browning creates essential flavor for your Italian Sausage Orzo Soup, so don’t rush this step. Once browned, transfer about half the sausage to a paper towel-lined plate and reserve for garnish later.

Step 2: Sauté the vegetables
In the same pot with the remaining sausage and its rendered fat, add the diced onion, carrots, and celery. Cook for 4-5 minutes until the vegetables begin to soften. Add the minced garlic, Italian seasoning, and red pepper flakes (if using), cooking for another 30 seconds until fragrant. The aromatics will bloom in the oil, releasing their flavor compounds throughout the soup.

Step 3: Build the broth
Add the diced tomatoes with their juices and stir, scraping up any browned bits from the bottom of the pot. Pour in the chicken broth and bring to a gentle boil. Reduce the heat to medium-low, cover partially, and simmer for 10 minutes to allow the flavors to meld and the vegetables to soften further.

Step 4: Cook the orzo
Add the dry orzo pasta to the simmering broth. Cook, stirring occasionally, until the orzo is tender but still has a slight bite, about 8-10 minutes. Keep an eye on the soup as the orzo cooks since it will absorb liquid and might require additional broth if the soup becomes too thick.

Step 5: Finish and serve
Once the orzo is cooked, stir in the fresh spinach and allow it to wilt for 1-2 minutes. Add the lemon juice and grated Parmesan, stirring to incorporate. Taste and adjust seasoning with salt and pepper as needed. Ladle the hot Italian Sausage Orzo Soup into bowls, top with the reserved crispy sausage, extra Parmesan cheese, and a sprinkle of fresh basil.

Variations

Creamy Version
Transform your Italian Sausage Orzo Soup into a luxurious treat by adding 1/2 cup of heavy cream or full-fat coconut milk during the final 5 minutes of cooking. The cream creates a silky, rich broth that perfectly complements the spice from the sausage while mellowing the tomato’s acidity. This variation works particularly well during colder months when you’re craving something extra comforting.

Vegetarian Adaptation
Create a meat-free version by replacing the Italian sausage with 8 ounces of chopped mushrooms (cremini or portobello work best) and a can of white beans for protein. Add 1 tablespoon of smoked paprika and an extra tablespoon of Italian herbs to compensate for the flavor typically provided by the sausage. The mushrooms offer a meaty texture while the beans provide satisfying protein, making this sausage-free orzo soup equally hearty and fulfilling.

Mediterranean Twist
Brighten up the traditional Italian Sausage Orzo Soup with Mediterranean flavors by adding 1/2 cup chopped kalamata olives, 1 cup artichoke hearts, and substituting the spinach with fresh arugula. Finish with crumbled feta instead of Parmesan for a tangy, salty punch. This variation brings a sunny, vibrant character to the classic soup, perfect for spring and summer enjoyment.

Storage and Serving

Your Italian Sausage Orzo Soup will keep beautifully in an airtight container in the refrigerator for 3-4 days. As it sits, the orzo will continue to absorb the broth, so when reheating, you’ll likely need to add a splash of chicken broth or water to reach your desired consistency. For longer storage, this soup freezes well for up to 3 months, though for best results, consider freezing it before adding the orzo, then cooking fresh pasta when you reheat.

For serving, pair this robust soup with a simple side salad dressed with lemon vinaigrette to provide a refreshing contrast to the soup’s richness. A piece of crusty Italian bread or garlic bread makes the perfect companion for sopping up every last drop of the flavorful broth. For an elegant dinner presentation, serve the Italian Sausage Orzo Soup in shallow bowls with a swirl of good olive oil on top, a sprinkle of red pepper flakes, and a few fresh basil leaves to add a restaurant-quality finish to your homemade masterpiece.

FAQs

Can I use a different pasta instead of orzo?
Absolutely! While orzo creates the ideal texture for this Italian Sausage Orzo Soup, small pasta shapes like ditalini, stelline (little stars), or even broken spaghetti work well. Adjust cooking time according to the pasta package instructions, as some shapes may cook faster or slower than orzo.

Is this soup spicy?
The spice level depends entirely on your choice of Italian sausage. Using sweet Italian sausage creates a mild soup, while hot Italian sausage adds a pleasant kick. You can always adjust the heat by adding more red pepper flakes to taste or omitting them completely.

Can I make this soup ahead of time?
Yes, but with one consideration. The soup base can be prepared 1-2 days ahead, but add the orzo just before serving. Otherwise, the pasta will continue absorbing liquid and may become mushy when reheated.

What can I substitute for spinach?
Kale, Swiss chard, or escarole make excellent alternatives to spinach in this soup. Heartier greens like kale will need a few extra minutes of cooking time to soften properly.

Can I make this soup in a slow cooker?
Yes! Brown the sausage and sauté the vegetables as directed, then transfer to a slow cooker with the broth and tomatoes. Cook on low for 6-7 hours or high for 3-4 hours, adding the orzo during the final 30 minutes of cooking time. Stir in the spinach, lemon juice, and cheese just before serving.
