• Olive oil: For sautéing and a smooth finish.
• Yellow onion: One medium, diced.
• Carrots: Two medium, sliced into thin rounds.
• Celery: Two ribs, sliced.
• Garlic: 3–4 cloves, minced.
• Zucchini: One small, diced.
• Baby spinach or kale: About 3 cups, chopped if using kale.
• Canned diced tomatoes: One 14.5-ounce can, drained (optional for a light blush broth).
• Orzo: 3/4 cup, uncooked.
• Vegetable broth: 6 cups, low-sodium.
• Lemon: Zest of 1 lemon and juice of 1–2 lemons, to taste.
• Fresh herbs: 1/4 cup chopped parsley and/or dill.
• Bay leaf: One.
• Seasonings: 1/2 teaspoon dried oregano, 1/2 teaspoon dried thyme, pinch of red pepper flakes (optional).
• Salt and black pepper: To taste.
• Parmesan rind (optional): For a richer broth if not strictly vegan.
• Finishing touches: Extra olive oil and grated Parmesan or vegan parm (optional).

Method

 

1. Warm the pot: Heat 2 tablespoons olive oil in a large pot over medium heat until shimmering.
2. Build the base: Add onion, carrots, and celery with a pinch of salt. Cook 5–7 minutes, stirring, until the onion is soft and edges are slightly golden.
3. Add garlic and spices: Stir in garlic, oregano, thyme, and red pepper flakes. Cook 30–60 seconds until fragrant.
4. Layer in veggies: Add zucchini and cook 2 minutes to soften. If using tomatoes, stir them in now and cook 1 minute.
5. Pour in broth: Add vegetable broth, bay leaf, and Parmesan rind if using. Bring to a gentle boil.
6. Simmer the orzo: Stir in orzo. Reduce to a lively simmer and cook 8–10 minutes, stirring often so orzo doesn’t stick. Taste and season with salt and pepper.
7. Greens and zest: Stir in spinach or kale and the lemon zest. Cook 2–3 minutes until greens are tender and orzo is al dente.
8. Finish with lemon and herbs: Remove the bay leaf (and rind). Stir in lemon juice and fresh parsley/dill. Start with the juice of 1 lemon, then add more to taste.
9. Serve: Ladle into bowls and finish with a swirl of olive oil and a sprinkle of Parmesan if you like. Crack fresh pepper over the top.

Why This Recipe Works

This soup hits a sweet spot between simple and flavorful. The aromatics build a savory base, while the lemon adds brightness that keeps each spoonful lively.

Orzo gives you a comforting, almost creamy texture without heavy cream. A quick sauté draws out flavor from the vegetables before they simmer, and finishing with fresh herbs keeps everything tasting vibrant. It’s hearty enough for lunch, light enough for dinner, and easy to scale up.

Keeping It Fresh

Orzo keeps absorbing liquid as it sits. For the best leftovers, cook the orzo separately and add it to bowls when serving. If you’ve already cooked it together, add a splash of broth or water when reheating to loosen the texture.

Store the soup (without orzo, ideally) in an airtight container in the fridge for up to 4 days. It also freezes well for 2–3 months; add fresh lemon and herbs after thawing to revive the flavor.

Health Benefits

• Vegetable-rich: You’re getting fiber, antioxidants, and a wide range of vitamins from carrots, greens, zucchini, and tomatoes.
• Lighter comfort: Orzo gives body without heavy cream or butter, keeping the soup satisfying yet light.
• Lemon lift: Lemon adds brightness and vitamin C, which helps the flavors pop and supports immune health.
• Heart-friendly fats: Olive oil brings healthy monounsaturated fats and a silky finish.
• Customizable nutrition: Add chickpeas or white beans for plant protein, or swap whole wheat orzo for more fiber.

Common Mistakes to Avoid

• Overcooking the orzo: It can turn mushy fast. Keep the soup at a simmer, stir often, and pull it off the heat as soon as it’s al dente.
• Adding lemon too early: Long cooking dulls its brightness.

  Add zest during simmering, but save most of the juice for the end.

• Skipping the sauté: Tossing raw veggies into broth makes a flat-tasting soup. Sautéing builds deeper flavor.
• Not salting in layers: Season lightly at each step—aromatics, broth, and at the end. It prevents a bland or overly salty finish.
• Overcrowding the pot: If your pot is small, cook in stages.

  Too many veggies at once can steam instead of sauté.

Variations You Can Try

• Greek-inspired: Add 1 cup chickpeas, a handful of chopped dill, and serve with feta and a drizzle of olive oil.
• Lemony chicken: Stir in shredded rotisserie chicken and a splash more lemon. Great for using leftovers.
• Creamy lemon: Whisk in 1/4 cup tahini or a splash of coconut milk for a silky texture without dairy.
• Whole-grain swap: Use whole wheat orzo or small farro. Adjust simmer time and add more broth as needed.
• Extra green: Add peas, asparagus tips, or chopped broccolini in the last 3–4 minutes.
• Spice it up: A pinch of cumin and coriander adds warmth; finish with fresh cilantro and lemon.

FAQ

Can I make this gluten-free?

Yes.

Use gluten-free orzo or another small gluten-free pasta. You can also swap in cooked rice or quinoa and add it to bowls when serving to avoid mushy leftovers.

How do I keep the orzo from soaking up all the broth?

Cook the orzo separately in salted water and store it apart from the soup. Combine in bowls just before eating.

For leftovers, keep extra broth on hand to thin as needed.

What if I don’t have fresh herbs?

Use 1–2 teaspoons dried herbs total. Add them with the garlic and spices so they can bloom in the oil. If possible, finish with a little lemon zest to keep the flavor fresh.

Can I use other vegetables?

Absolutely.

Bell peppers, mushrooms, green beans, or corn work well. Just add firmer vegetables earlier and delicate ones near the end so they don’t overcook.

How long does it last in the fridge?

Up to 4 days. If the orzo is in the soup, you’ll likely need to add broth or water when reheating.

If stored separately, both reheat beautifully on the stovetop or in the microwave.

What’s the best way to reheat?

Warm gently on the stove over medium heat. Add a splash of water or broth as needed, then brighten with a squeeze of lemon and a pinch of salt before serving.

Can I make it in an Instant Pot?

Yes. Sauté aromatics and veggies on Sauté mode, add broth and orzo, then cook on High Pressure for 3 minutes with quick release.

Stir in greens, lemon, and herbs at the end.
