Vegetable Orzo Soup

Vegetable orzo soup is the comfort food dish you need for chilly weather. This hearty soup is loaded with vegetables and orzo pasta, and has that classic minestrone flavor everyone loves.

The best part is how easily it comes together. Everything cooks in one pot, and you can have dinner on the table in 30 minutes. The orzo makes the soup hearty, while the mix of vegetables packs it with flavor.

I make this easy vegetable orzo soup and this Vegetable Barley Soup all the time during the colder months. It has everything I want in a soup: tons of vegetables, a rich tomato broth, and enough substance to feel like a real meal.

I love how flexible this recipe is. I use whatever vegetables I have on hand, and it always turns out delicious. The garbanzo beans add protein and make the soup really filling, so you don’t need anything else on the side.

The Italian seasoning has all the classic herbs you’d find in minestrone. You get that familiar flavor without having to measure out oregano, basil, and thyme separately.

I usually serve this with some crusty bread for dipping and a sprinkle of Parmesan cheese on top. The soup is hearty enough to stand on its own, but the bread is perfect for soaking up every last bit of that delicious broth.

Ingredient Notes

See the printable recipe card below for all ingredients, specific measurements, and complete instructions.

• Olive oil: This gets the vegetables started and adds a nice base flavor to the vegetable orzo soup.
• Onion: Yellow or white onion both work great.
• Garlic: Fresh garlic is best here. Four cloves might seem like a lot, but it mellows out as it cooks and adds amazing flavor.
• Celery and carrots: These are classic soup vegetables that add sweetness and texture. Chop them into small, bite-sized pieces so they cook evenly.
• Zucchini: This cooks quickly, so you don’t need to add it at the very beginning. One small zucchini is about a cup when diced.
• Petite diced tomatoes: The petite dice is perfect for soup because the pieces are already small. Regular diced tomatoes work too if that’s what you have.
• Vegetable broth or chicken broth: Either one works. Vegetable broth keeps it vegetarian, but chicken broth adds a deeper flavor.
• Italian seasoning: This blend has all the herbs you need in one container.
• Garbanzo beans: Also called chickpeas, these add protein and make the soup more filling. Be sure to drain and rinse them first.
• Orzo pasta: This tiny pasta looks like rice but has that wonderful pasta texture. It cooks right in the soup and soaks up all the flavors.
• Frozen peas: No need to thaw them first. They warm up from the residual heat when you stir them in at the end.
• Fresh baby spinach: This wilts down dramatically, so two ounces is perfect. Add it at the end so it stays bright green.
• Kosher salt and black pepper: Start with about half a teaspoon of salt, then taste and adjust at the end.

How To Make Vegetable Orzo Soup

Heat the olive oil in a large pot over medium-high heat. Once it’s hot, add the diced onion, celery, carrots, and half a teaspoon of kosher salt. Cook for 3-4 minutes, stirring occasionally, until the vegetables start to soften and the onion becomes translucent.

Add the zucchini, diced tomatoes, garlic, Italian seasoning, and garbanzo beans to the pot. Pour in the broth and give everything a good stir to combine. Bring the soup to a simmer.

Once the soup is simmering, add the peas and orzo pasta. Stir it in and let the soup cook for about 10 more minutes, until the orzo is al dente. You want it to have a slightly firm and chewy texture, not mushy. The vegetables should be nice and tender at this point.

Add the fresh spinach. Stir everything together, then simmer for a minute until the spinach is wilted.

Taste the soup and add more salt and pepper as needed. Ladle the soup into bowls and top with Parmesan cheese and fresh herbs if you like.

Storing and Freezing

Store: Keep leftover vegetable orzo soup in an airtight container in the refrigerator for 2-3 days. The orzo will continue to absorb liquid as it sits, so the soup will get thicker. When you reheat it, add a splash of broth or water to thin it back out to your preferred consistency.

Freeze: This soup freezes well for up to 3 months. Let it cool completely, then transfer it to freezer-safe containers or bags. Leave a little room at the top since the soup will expand as it freezes. Thaw it overnight in the refrigerator, then reheat it on the stovetop over medium heat. Add extra broth to get it back to the right consistency.

Substitutions and Variations

• Make it heartier. Add some cooked Italian sausage or diced chicken for extra protein. Brown the meat first, then set it aside and add it back in with the broth.
• Switch up the pasta. Use ditalini, small shells, or broken spaghetti instead of orzo. Just adjust the cooking time based on the package directions.
• Add more vegetables. Throw in some diced bell peppers, green beans, or kale. Just add heartier vegetables early with the carrots, and quicker-cooking ones with the zucchini.
• Use white beans. Cannellini or great northern beans work just as well as garbanzo beans and give the soup a creamier texture.
• Make it creamy. Stir in a splash of heavy cream or half-and-half at the end for a richer soup.

Recipe Tips

• Watch the orzo carefully once you add it. Orzo can go from perfectly al dente to overcooked and mushy quickly, so start checking it at around 8 minutes.
• Add the spinach off the heat. If you keep the pot on the burner, the spinach can overcook and turn that dull olive color instead of staying bright green.
• Start with less salt than you think you need. The broth, canned tomatoes, and beans all have sodium, so taste the soup at the end and adjust from there.
• Use a large pot that holds at least 5 quarts. This recipe makes a generous amount of soup, and you need room to stir everything without it splashing over the sides.

Why is my soup too thick?

The orzo absorbs a lot of liquid, especially as the soup sits. Just add more broth or water until it reaches the consistency you like. Start with half a cup and go from there.

Can I make this in a slow cooker?

Yes! Add everything except the orzo, spinach, and peas to your slow cooker. Cook on low for 6-7 hours or high for 3-4 hours. About 20 minutes before serving, stir in the orzo and let it cook until tender, then add the spinach and peas.
