Ingredients for iranian soup

Fresh herbs and bright lemon create this elegant Persian-inspired soup's signature clarity and depth.

The herb stems are the secret to that crystal-clear broth. Look for fresh, vibrant stems at your local farmers market—they've got more flavor than anything from the grocery store's plastic containers. Whole Foods or local Persian markets often carry the best quality tarragon and dill. If you can't find fresh stems, dried herbs work in a pinch (use half the amount), but the texture won't be as smooth. The parsley and dill leaves you'll add later should be bright green with no yellowing—those wilted ones at the back of the fridge won't cut it here. (Trust me, you'll taste the difference.)

No fresh tarragon? Fresh marjoram or basil can stand in, though the flavor will shift slightly. Running low on lemon juice? Substitute lime juice at the same amount, but the color will be different. The broth is flexible—if you're serving this to guests who prefer it richer, stir in 1 tbsp of heavy cream per serving at the end. For extra depth, add 1 tsp of saffron threads steeped in 2 tbsp warm water when you strain the broth. (It's worth the splurge for special occasions.)

This soup tastes even better the next day as flavors meld. Store the broth in an airtight container in the fridge for up to 5 days—the herbs keep their brightness surprisingly well. For longer storage, freeze portions in ice cube trays (they thaw perfectly for quick meals). The butter and olive oil should be added fresh when reheating—always drizzle them in at the end to maintain that velvety texture. Serve with the crusty bread slices toasted in the oven for 3-5 minutes at 375°F.

Step-by-step instructions for herbed lemon and herb clarified broth

Here's how to create a bright, aromatic Iranian-inspired broth that's light yet deeply flavorful.

In a large pot, combine the 1 cup fresh parsley stems, 0.5 cup fresh tarragon stems, and 0.5 cup fresh dill stems with the 6 cups chicken broth. Bring to a gentle boil over medium-high heat, then immediately reduce to a simmer and cover partially. Let it cook for 20 minutes—this draws out all the herbal essence without making the broth bitter.

I like to stir the stems gently after 10 minutes to prevent them from sticking to the bottom. The broth should develop a vibrant green hue and a fragrant aroma that fills your kitchen. This is the foundation of your soup's complex flavor profile, so don't rush this step.

After simmering, carefully strain the broth through a fine-mesh sieve into a clean pot, pressing gently on the stems to extract maximum flavor. Discard the used stems. Return the strained broth to the pot and add the 0.5 cup fresh lemon juice and 1 tsp fresh lemon zest. Stir well to combine.

Bring the broth back to a simmer over medium heat for 5 minutes to let the citrus brighten the flavors. The lemon zest will infuse the broth with its signature tangy aroma—this is what makes this soup distinctly Iranian. Taste and adjust seasoning with the 1.5 tsp salt if needed, remembering that the broth will reduce slightly as it cooks further.

In a separate bowl, whisk together the 0.5 cup fresh flat-leaf parsley, 0.25 cup fresh tarragon leaves, and 0.25 cup fresh dill leaves with the 0.25 cup extra-virgin olive oil. This creates a natural clarifying agent that will give your broth that signature silky texture. Slowly whisk this mixture into the simmering broth while stirring continuously.

Let the broth simmer gently for 10 minutes uncovered. You'll notice the herbs will rise to the surface and form a frothy layer. This is completely normal—it's the oils and fine particles clarifying. Carefully ladle the broth through a fine-mesh strainer into a clean pot, leaving the frothy layer behind. This final straining step is what gives this soup its characteristic clarity and refined texture.

Return the clarified broth to medium-low heat and let it warm through for 2-3 minutes. In a small saucepan, melt the 2 tbsp unsalted butter over low heat until just melted. Drizzle the butter into the broth while stirring gently—this adds richness without overpowering the delicate herbal notes.

Ladle the finished broth into bowls and serve immediately with the 4 slices crusty bread. The contrast between the silky broth and the hearty bread creates the perfect balance. Each spoonful should deliver bright citrus notes, fresh herbal aromas, and just the right amount of body. This soup is best enjoyed fresh while the herbs are at their peak flavor.

Regional styles of this recipe

Tehran's Classic Ash-e Shireh

This elegant Persian soup from Tehran’s culinary tradition replaces the clarified broth with a delicate chicken and rice base. Start with 1 lb boneless chicken thighs poached in 4 cups water with 1 bay leaf and ½ tsp turmeric until tender.

Shred the meat and combine it with ½ cup basmati rice, 1 cup yogurt, and 1 tbsp dried fenugreek leaves (a key Persian herb). Simmer until rice is tender, then finish with 2 tbsp chopped mint and 1 tsp saffron steeped in warm water.

The result is a creamy, herbaceous soup that’s lighter than the clarified version but equally comforting. 🌿

Isfahan's Spiced Lamb Soup

Isfahan’s version, Ash-e Ghavami, transforms this soup into a hearty lamb stew. Brown 1 lb lamb shoulder in 2 tbsp ghee, then add 1 large onion (diced), 3 garlic cloves (minced), and 1 tsp ground cinnamon.

Deglaze with 1 cup white wine, then add 6 cups chicken broth, 1 cup chickpeas, and 1 cup spinach. Simmer until lamb is tender, then finish with 1 tbsp lemon juice and 2 tbsp chopped cilantro.

The lamb adds deep umami richness, while the chickpeas and spinach create a satisfying texture contrast. The cinnamon and wine give it a sophisticated depth that’s distinctly Isfahani. 🍷

Northern Azerbaijan's Herb-Forward Ash

In Azerbaijan’s northern regions, this soup becomes Ash-e Sabzi, a vibrant herb-forward dish. Replace the clarified broth with a thick green paste made from 2 cups finely chopped parsley, 1 cup cilantro, ½ cup dill, ½ cup mint, and 1 garlic clove.

Cook the paste in 2 tbsp olive oil for 5 minutes, then add 4 cups chicken broth, 1 cup shredded chicken, and 1 tbsp lemon juice. The paste gives the soup a bold, herby flavor that’s almost like a pesto-infused broth.

Serve with lavash bread for dipping—this version is a staple in Azerbaijan’s highland cuisine. 🌱

Yazd's Clarified Broth with Pomegranate

Yazd’s arid climate inspired a fruit-infused twist on the clarified broth. After clarifying the broth as directed, stir in ¼ cup pomegranate molasses and 1 tsp rose water for a sweet-tart balance. Garnish with 2 tbsp pomegranate seeds and a drizzle of extra-virgin olive oil.

The pomegranate adds a juicy contrast to the silky broth, while rose water lends a floral note that’s quintessential to Yazd’s culinary style. This version is especially popular during Persian New Year (Nowruz) celebrations. 🍇

Modern Iranian Fusion: Clarified Broth with Shrimp

For a coastal-inspired twist, add 1 lb shrimp (peeled and deveined) to the clarified broth during the final 5 minutes of simmering. The shrimp absorb the herbal and citrus flavors beautifully, turning this into a lighter, seafood-forward soup.

Finish with 1 tbsp chopped chives and a squeeze of lemon. This fusion version works perfectly as a summer starter or light main course, especially when paired with grilled flatbread. The shrimp’s sweetness complements the broth’s brightness without overpowering it. 🦐

Vegetarian Adaptation with Lentils

To make this soup vegetarian-friendly, replace the chicken broth with 6 cups vegetable broth and add 1 cup green lentils during the initial 20-minute simmer. The lentils absorb the herbal flavors while adding protein and earthiness. For extra richness, stir in 2 tbsp tahini at the end.

This version is just as satisfying and aligns with Iran’s long tradition of plant-based soups, like Ash-e Laleh. It’s a great option for those who want to keep the soup’s elegance without meat. 🌱
