1-First Step: Sauté the Aromatics
Begin by heating 1 tablespoon of olive oil in a large stockpot over medium-high heat. Once the oil is shimmering (but not smoking), add the diced onion, carrots, and celery to the pot. Sauté these vegetables for 5 to 7 minutes, stirring occasionally, until they’ve softened and become fragrant. The onions should be translucent, and the carrots will start to brighten in color. This step builds the flavor foundation of your Italian Orzo Spinach Soup Recipe, releasing the natural sugars in the vegetables and creating a wonderful aroma in your kitchen.

2-Second Step: Add Garlic and Seasonings
Turn the heat down to medium to prevent the garlic from burning, then add the 6 minced garlic cloves and 1/2 teaspoon of crushed red pepper flakes. Sauté for 2 minutes, stirring frequently. You’ll notice the garlic becoming fragrant that’s when you know it’s ready. Be careful not to let the garlic brown too much, as this can make it bitter. The red pepper flakes will start releasing their heat, infusing the oil with a subtle spiciness that will permeate the entire soup. For those who prefer more heat, feel free to add up to a full teaspoon of red pepper flakes at this stage. The combination of garlic and gentle spice creates a perfect base for the broth that’s coming next.

3-Third Step: Create the Soup Base
Now it’s time to add the liquids and tomatoes to transform your sautéed vegetables into soup. Pour in 6 to 8 cups of chicken or vegetable stock the amount depends on whether you prefer a thicker or broth-ier soup. I usually start with 7 cups and adjust as needed later. Add the entire 14-ounce can of fire-roasted diced tomatoes along with their juices, plus 1 1/2 tablespoons of Italian seasoning. Stir everything together to combine.

Increase the heat to bring the mixture to a simmer. You’ll see small bubbles forming around the edges of the pot. Once simmering, reduce the heat to medium-low to maintain a gentle simmer. This temperature allows flavors to develop without cooking off too much liquid or overcooking ingredients too quickly.

4-Fourth Step: Cook the Orzo
Once your soup base is simmering nicely, it’s time to add the star ingredient the orzo pasta. Stir in 1 cup of uncooked orzo pasta, making sure it’s fully submerged in the liquid. Cover the pot with a lid to trap heat and steam.

Continue simmering, stirring occasionally to prevent the orzo from sticking to the bottom of the pot. The orzo will absorb some of the broth as it cooks, which is exactly what we want it helps flavor the pasta from the inside out. Cook until the orzo is just barely al dente, which typically takes about 8-12 minutes but can vary depending on the brand. Remember, the pasta will continue to cook slightly even after you’ve turned off the heat, so it’s better to slightly undercook it now than to end up with mushy orzo later.

Check the package directions for the specific orzo you’re using, as cooking times can vary. During this step, you might notice the soup thickening this is normal and expected. If the soup becomes too thick for your liking, you can add a bit more stock, quarter cup at a time.

5-Fifth Step: Incorporate the Spinach
When the orzo is just about done, it’s time to add the fresh spinach. Stir in 2 large handfuls of baby spinach or kale (about 8 ounces) into the soup. The spinach will look overwhelming at first, but it will wilt down significantly within minutes. Cook for 2-3 minutes more, stirring occasionally, until the spinach has wilted completely and turned a vibrant green color.

This step adds not only beautiful color but also incredible nutritional value to your soup. Adding the greens at the very end preserves their texture, bright color, and maximum nutritional content. If you cook them for too long, they can become slimy and lose their vibrant appearance. For those who prefer a more substantial green, kale can be used instead of spinach and may require an additional minute or two to become tender.

Once the spinach is wilted, taste your soup and adjust the seasoning with salt and black pepper as needed. The amount of salt needed will depend largely on the sodium content of your stock, so it’s important to taste before adding extra. I usually start with 1/2 teaspoon of salt and several grinds of black pepper, then adjust from there.

6-Final Step: Serving Your Italian Orzo Spinach Soup
Once your soup is perfectly seasoned and all ingredients are cooked to your liking, it’s time to serve immediately. Ladle the hot soup into bowls, ensuring each serving gets a generous amount of orzo, vegetables, and broth.

For an extra special touch, top with optional garnishes like freshly-grated Parmesan cheese, chopped fresh basil, and lemon wedges. The Parmesan adds a salty, umami element while the fresh basil brightens up the dish. A squeeze of lemon juice right before eating can lift all the flavors and add a bright, tangy note that balances the richness of the soup.
