Greek Spinach and Orzo Soup with Lemon

Greek spinach and orzo soup is a lemony, herb-scented one-pot soup made with tender pasta, leafy spinach, vegetables, and chickpeas. It draws on familiar Greek flavors such as dill, oregano, and lemon, while using orzo for a comforting, easy-to-eat bowl; recipes and family versions vary, so the ingredients can be adjusted to taste.

Ingredients

2 tablespoons (30 ml) extra-virgin olive oil
1 medium yellow onion, finely diced (about 150 g)
2 medium carrots, diced (about 150 g)
2 celery ribs, diced (about 80 g)
3 garlic cloves, minced (about 9 g)
1 teaspoon dried oregano (about 1 g)
1 bay leaf
8 cups (1.9 L) low-sodium vegetable broth
1 can chickpeas, drained and rinsed (15 ounces/425 g can; about 240 g drained)
1 cup dry orzo (about 170 g)
5 ounces fresh baby spinach (about 140 g), roughly chopped if the leaves are large
1 large lemon (about 180 g), finely zested, plus 3 tablespoons (45 ml) juice
1 teaspoon fine salt (about 6 g), plus more to taste
¼ teaspoon freshly ground black pepper (about 0.5 g), plus more to taste
¼ cup chopped fresh dill (about 10 g), divided
½ cup crumbled feta (about 75 g), for serving, optional

Instructions

Prepare the vegetables and lemon. Dice the onion, carrots, and celery into small, similar-sized pieces so they soften evenly. Mince the garlic, rinse and drain the chickpeas, and zest the lemon before juicing it. Keep the lemon juice for the end; adding it after cooking preserves its bright flavor.
Soften the vegetables. Heat the olive oil in a large heavy-bottomed pot or Dutch oven over medium heat. Add the onion, carrots, and celery. Cook for 6 to 8 minutes, stirring every so often, until the onion is translucent and the vegetables are beginning to soften. They should not brown deeply. Stir in the garlic and oregano and cook for about 30 seconds, just until fragrant.
Simmer the broth and chickpeas. Add the bay leaf, vegetable broth, chickpeas, salt, and pepper. Bring the liquid to a boil, then reduce the heat to maintain a gentle simmer. Cook uncovered for 10 minutes, stirring once or twice. This gives the vegetables time to become tender and lets the chickpeas take on the seasoned broth. If your broth is already salty, begin with less salt and adjust later.
Cook the orzo in the soup. Stir in the dry orzo and return the broth to a gentle simmer. Cook uncovered for 9 to 11 minutes, stirring frequently, especially across the bottom of the pot. Start checking at 9 minutes: the pasta should be tender but still hold its shape. Orzo can settle and stick if left undisturbed, and it continues to soften slightly in hot broth.
Wilt the spinach. Turn the heat to low and stir in the spinach in a couple of handfuls. Cook for 1 to 2 minutes, just until the leaves are wilted and vivid green. If the pot looks very full at first, wait for the first handful to collapse before adding the rest.
Finish and season. Remove the bay leaf. Stir in the lemon zest, 3 tablespoons lemon juice, and half of the dill. Taste the broth and add more salt, pepper, or lemon juice as needed. The soup should taste savory and fresh, not sharply sour; add lemon a teaspoon at a time if you are unsure. Ladle into bowls and finish with the remaining dill and feta, if using.

Tips

Choose your broth carefully. Low-sodium vegetable broth makes it easier to control the final seasoning. If you have regular broth, hold back some of the listed salt until the soup is finished. Chicken broth also works, though it gives the soup a less strictly vegetarian character.
Stir after adding orzo. Orzo is small and can sink to the base of the pot, where it may catch before it is tender. Stir every minute or two while it cooks, and keep the liquid at a gentle simmer rather than a hard boil.
Balance the lemon at the end. Lemons vary in size and sharpness, so taste before adding extra juice. Zest contributes fragrant citrus flavor without as much acidity; use only the yellow outer peel, not the bitter white pith.
Plan for pasta to thicken the soup. Orzo absorbs broth as it sits. If you prefer a brothy bowl, serve soon after cooking or keep extra broth on hand for reheating. For a gluten-free version, use a gluten-free small pasta and follow its package timing; texture and thickening may differ.

Serving Suggestions

Serve the soup hot in wide bowls, with the feta and fresh dill scattered over each portion. A wedge of lemon at the table lets everyone adjust the brightness to taste. Warm crusty bread, pita, or toasted sourdough is useful for soaking up the broth, while a simple cucumber-and-tomato salad makes a fresh contrast. For a fuller meal, add olives or a small plate of roasted vegetables alongside.

The chickpeas and orzo make each bowl substantial, so the soup can stand on its own for lunch or a casual dinner. If serving it as a starter, use smaller portions and keep the feta as an optional topping. Set out extra black pepper and lemon rather than adding a large amount of either to the whole pot; individual bowls can then be seasoned without changing the balance for everyone.

Variations

Make it with rice: Replace the orzo with ¾ cup (about 145 g) long-grain rice. Add it with the broth and chickpeas, then simmer until tender according to the rice package, usually about 15 to 20 minutes. The grains absorb liquid differently, so check the pot and add broth if needed. This brings the soup closer to Greek spinach-and-rice preparations often called spanakorizo, though this recipe remains a soup.

Use frozen spinach: Substitute 8 ounces (225 g) frozen chopped spinach, thawed and squeezed dry, for the fresh spinach. Stir it in near the end and heat through for about 2 minutes. Frozen spinach has a denser texture and less fresh, leafy character, but it is convenient and works well in the broth.

Make it dairy-free or add more herbs: Leave off the feta for a dairy-free bowl; the lemon and dill still give the soup plenty of character. You can also add 1 tablespoon (about 4 g) chopped fresh mint with the dill for a cool herbal note. Mint is optional and changes the aroma, so start with a small amount.

Add more vegetables: Stir in 1 cup (about 100 g) sliced zucchini with the broth, or add ½ cup (about 75 g) frozen peas with the spinach. Zucchini should simmer until tender, while peas need only a short heating. Avoid adding both in large amounts unless you also increase the broth, or the soup may become crowded and thick.

Storage and Reheating

Cool leftovers promptly and refrigerate them within 2 hours in a covered, shallow container. The soup keeps for 3 to 4 days in the refrigerator. As it rests, the orzo will absorb broth and become softer, so the next-day soup will be thicker than it was when freshly made. For the best texture, store extra broth separately if you know you are cooking ahead, or simply plan to loosen the leftovers before serving.

Reheat a portion gently in a saucepan over medium-low heat, stirring often, and add broth or water a little at a time until it reaches your preferred consistency. Heat leftovers to 165°F (74°C), checking with a food thermometer. A microwave also works: cover the bowl loosely, heat in short intervals, and stir between intervals so the soup warms evenly. Add fresh lemon juice, dill, or feta after reheating rather than cooking those toppings for a long time.

You can freeze the soup for about 2 to 3 months in freezer-safe containers, leaving a little space for expansion. The spinach may soften and the orzo may turn quite tender after thawing, so freezing is best when convenience matters more than a just-cooked pasta texture. Thaw overnight in the refrigerator, then reheat to 165°F (74°C). If making a batch specifically to freeze, cook and freeze the soup before adding the orzo; cook fresh orzo separately and add it when serving for a firmer result.

Frequently Asked Questions

Can I cook the orzo separately?

Yes. Cook the orzo in a separate pot of salted water, drain it, and add it to individual bowls before ladling in the soup. This keeps the pasta from absorbing as much broth during storage and is especially helpful if you expect leftovers. Cooked separately, the orzo may need a little extra seasoning because it will not simmer in the broth.

Can I use another small pasta shape?

Yes. Small shells, ditalini, or another soup pasta can replace orzo in the same general quantity by volume. Check the package instructions and begin tasting a few minutes before the suggested cooking time, since shapes vary. If you use a larger pasta, the soup may need a little longer to cook and more broth as the pasta expands.

Is this soup vegetarian?

It is vegetarian when made with vegetable broth and served without feta, if you also want it dairy-free. Check the broth label, since some prepared broths contain animal ingredients. For a vegan bowl, use vegetable broth and omit the feta; the chickpeas already provide substance, so no replacement topping is necessary.

Why did my soup become too thick?

The most common reason is that the orzo continued absorbing liquid after the pot came off the heat, or while the soup was refrigerated. Stir in warm broth or water a little at a time until it loosens. Taste again after adding liquid, because you may need a pinch of salt or a squeeze of lemon to restore the seasoning.

Can I make it ahead?

Yes, with a small adjustment for the pasta. Prepare the vegetables, broth, and chickpeas ahead, then refrigerate the soup base and cook the orzo in it shortly before serving. If you cook the complete recipe in advance, it is still good, but expect a thicker texture; reheat it with extra broth and finish with fresh dill and lemon.

What can I use instead of fresh dill?

Use 1 teaspoon (about 1 g) dried dill in place of the ¼ cup fresh dill, adding it with the oregano so it has time to soften in the broth. Dried dill is more concentrated and lacks the fresh, delicate finish of the herb, so use less. Parsley can provide a fresh green garnish, although its flavor is milder and less distinctive.
