One-pot Lemon Orzo Soup is cozy & comforting yet light, healthy, and wholesome โ made with simple ingredients and bursting with fresh, bright flavors! Now vegetarian and vegan, too!

Why Youโll Love This Recipe
With soup season here, Iโve been busy testing new recipes to add to my weekly rotation. First up, starting strong, is this cozy, comforting Greek-inspired lemon orzo soup. Itโs made with simple everyday ingredients yet bursting with bright, lemony flavors and tender orzo pasta, making it perfect to enjoy year-round.
If you already love vegan chicken noodle soup (and vegan jackfruit chicken noodle soup), this lemon and orzo soup is a must-try. It shares many familiar elements, but with the added sunny brightness of plenty of fresh lemon juice and zest. Plus, this recipe is 100% vegan, using your preferred plant-based protein. Iโve used tofu this time, but chickpeas or white beans work just as well.
Itโs quick, healthy, low-effort, budget-friendly, and the lemony broth is irresistibly delicious – whatโs not to love?! You might also enjoy this vegan chickpea noodle soup and orzo chickpea salad.
Ingredient Notes

Use regular or whole wheat orzo. Technically, other small pasta varieties will work, like ditalini, fideo, giant couscous, or labeled โsoup pasta.โ
What Could I Add?
- Spinach: (or kale) Add a few handfuls of this super nutritious green in the last 1-2 minutes.
- Creaminess: Add a few splashes of full-fat coconut milk or your favorite dairy-free cream/ silken tofu at the end. Tahini or cashew butter would also work.
- Dill: Use instead of or alongside parsley for plenty of herbaceous freshness.
- Red pepper flakes: To add a kick of heat.
- Nutritional yeast: For subtle nutty, slightly ‘cheesy’, umami-rich depth. How to use nutritional yeast guide here.
- Extra veggies: Like mushrooms, leek, zucchini, peas, green beans, etc.
How to Make Lemon Orzo Soup
Step 1: Dice the onion, slice the carrots and celery (about ยผ-inch thick), and mince the garlic. Also, (if using) dice the tofu into ยฝ-inch pieces. Then, heat the oil in a large, thick-based, lidded saucepan over medium heat. One hot, sautรฉ the chopped ingredients for 5 minutes until the onions are tender and translucent.
Step 2: Add the broth and Italian seasoning, mix well, bring to a boil, then add the tofu and lower heat to a simmer. Cover with a lid, and cook for 15 minutes.
Step 3: Uncover, gently mix, and add the orzo, cooking for about 10 minutes, until tender, stirring occasionally to prevent it sticking to the bottom.
Step 4: Remove the orzo lemon soup from the heat, add the parsley and zest plus juice one lemon directly into the pot. Finally, taste the soup and adjust the lemon, salt, and pepper levels to taste. Serve optionally garnished with more lemon wedges โ enjoy!
FAQs
Absolutely! In fact, I recommend making it in advance when possible because this vegetarian lemon orzo soup tastes even better on day two. Just note you may want to store the orzo separately, as it will continue to soak up broth while it sits.
You could add 1-2 tablespoons of flour at the end of step 2 and sautรฉ (to get rid of any raw flour flavor) for a minute before adding the broth/seasoning.
Yes, use gluten-free orzo or quick-cook brown rice.
Recipe Pro Tips
- To save time: Use pre-prepared mirepoix and/or minced garlic. Just note that the taste and freshness can vary.
- Lemon to taste: You can add as little or as much as you like.
- Leave it to rest: Orzo soup tastes even better after the flavors have time to meld.
- To avoid mushy orzo: While itโs easiest to cook it directly in the soup, making and storing the orzo separately ensures it wonโt become mushy or soaks up too much lemony broth.
What To Serve with Lemon Orzo Soup
- Bread for dipping โ like no-knead bread, vegan focaccia bread, or easy vegan dinner rolls.
- Side salad โ like a simple garden salad or vegan Caesar salad. Veggie-based salads like green bean salad or Greek cucumber salad also pair well.
- A sandwich โ I particularly love pairing this vegan lemon orzo soup with a light mushroom sandwich or a vegan grilled cheese for more heartiness.
Storage Instructions
Store any leftovers in an airtight container in the fridge for 4-5 days.
You may need to add more broth as the orzo continues to soak it up. If preferred, store the soup and orzo separately.
You can also freeze it (best minus the orzo – which will become mushy) for up to 3 months in Souper Cubes/Ziplock/Stasher bags. Allow it to thaw in the fridge overnight before adding the noodles and reheating. These are the labels I use.
Reheat it on the stovetop over medium-low heat or in a microwave for 1-2 minutes.

This is great – simple and cozy for a January afternoon! I added a can of Great Northern Beans because I didnโt have tofu on hand, and I highly recommend adding nutritional yeast. It took this soup to the. Ext level. Thanks for sharing!
I made this tonight and love it. Itโs refreshing, bright, and full of flavor! I think this way of serving tofu won me over as well. โฅ๏ธ
