Recipe Ingredients
You’ll need the following simple ingredients to make this vegan soup. See the recipe card for details on measurements and the full ingredient list.
- Tomatoes: I use POMI chopped tomatoes, but a can of crushed tomatoes will work, too.
- Orzo’s small, rice-like shape makes it perfect for this soup adding texture without overpowering the dish. But orzo isn’t just for soups—it also shines in cold dishes like Vegan Orzo Pasta Salad With Sunflower Seed Pesto.
- Frozen carrots and peas: I keep weeknight meals easy-peasy, so frozen carrots and peas are my go-to for this recipe.
- Beans: Any white beans will go well in this soup. Try cannellini or navy beans.
- Vegetable Broth: I prefer veggie base paste instead of boxed vegetable stock. It lets me dial in the flavor just right, making everything taste more intense. I scoop a spoonful of the paste into the soup, add 5 cups of water, and give it a good stir.
- Spices: Substitute the herbs for 1 ½ tablespoons of this Homemade Italian Seasoning.
Variations
Throw in whatever veggies you have on hand. Zucchini, bell peppers, or green beans would all be great additions to bulk up the soup.

Create a mirepoix by chopping fresh carrots into small pieces and adding them along with the celery. Then, follow the recipe by adding the frozen peas as directed.
How To Make Vegetable Orzo Soup
Here are pics of the process. See the recipe card for detailed instructions.
Step 1: Sauté the Shallots. Heat the olive oil in a large pot or Dutch oven over medium heat. Add the minced shallots and sauté for 3-4 minutes until soft and translucent.
Step 2: Add Garlic and Celery. Stir in the minced garlic and diced celery, cooking for another 2-3 minutes until fragrant.
Step 3: Toast the Orzo. Add the orzo pasta to the pot, stirring to coat it with the olive oil and aromatics. Toast the orzo for 1-2 minutes, stirring frequently to prevent sticking.
Step 4: Add Broth, Tomatoes, and Seasonings. Pour in the vegetable broth and tomatoes. Stir well to combine, then add the dried basil, oregano, thyme, and red chili flakes. Bring the soup to a boil and stir occasionally.
Step 5: Simmer and Add Vegetables. Reduce heat to low. Add a bag of peas and carrots, and simmer for 10-11 minutes.
Step 6: Add Leafy Greens and Beans. Stir in your choice of beans and chopped spinach or kale, cooking until the greens wilt. Season with salt, pepper, and lemon juice. Top with herbs like fresh parsley if desired.
Recipe Tips
- Add just before serving to keep the spinach or kale bright and vibrant.
- When buying a bag of carrots and peas, make sure they are diced small to cook in the allotted time of this recipe.
- Swap or add other vegetables you have on hand, like zucchini, bell peppers, or green beans. This versatile recipe can be adapted to what’s in season or available in your kitchen.
- If the soup thickens too much as it cools, stir in a cup of water or broth to bring it back to a soupy consistency.
Top Tip
The orzo will continue to absorb liquid as it sits, so boiling it until al dente is ideal.
Serving Suggestions
- Grab a slice of warm, crusty bread or a hunk of baguette to mop up that delicious broth. And if you’re feeling fancy, garlic bread will take it to the next level.
- Keep it fresh with a light, zippy side salad dressed in a French vinaigrette.
- Sprinkle some vegan Parmesan cheese over the top when serving.
- Finish the soup with a fresh herb garnish like basil, mint, cilantro, or parsley.
- Top the soup with homemade vegan croutons for the perfect crunch.
Storage and Reheating
- Store any leftover soup in an airtight container in the fridge for up to 4 days. The flavors get better as it sits, so don’t be surprised if it tastes even more delicious the next day.
- When you’re ready to enjoy it again, microwave at 50 percent for 5 minutes or reheat it on the stove over low heat. If necessary, add a cup of water or broth to return it to your desired consistency.
Orzo Soup FAQS
While I highly recommend the vegetable base paste to control the intensity of flavor in the soup, you can use boxed vegetable broth instead. Just adjust the salt as needed since some broths can be saltier than others.
You will need to substitute the orzo with gluten-free orzo or other pasta.
Yes. Just add about three times the amount. Alternatively, make a bouquet of herbs (bouquet garni) to infuse the soup with flavor without leaving herb bits behind. This way, you get all the aromatic benefits, and you can easily remove the herbs before serving, keeping the soup smooth and clean. Generally,
a bouquet of herbs should simmer in the soup for about 25-30 minutes to infuse the flavor effectively.

Instructions
- Sauté the Aromatics: Heat the olive oil in a large pot over medium heat. Add the minced shallots and a pinch of salt. Sauté for about 3-4 minutes until they’re soft and translucent. Stir in the minced garlic and diced celery, and cook for another 2-3 minutes until fragrant.

- Add the Broth and Tomatoes: Pour in the vegetable broth and the tomatoes. Stir well to combine. Add the dried basil, oregano, thyme, and red chili flakes. Stir and bring the soup to a boil, stirring occasionally to ensure that the orzo does not stick to the bottom before it can absorb the liquid.

Great soup. It was tomatoey so I added the 6 cups of liquid to water it down a little bit instead of the 5. Will make it again!
