This ash reshteh soup recipe brings the comforting warmth of Persian home cooking to your kitchen with its fragrant spiced broth and satisfying texture contrast. 💛 The secret lies in slow-simmering lamb shanks with aromatic spices until they melt into the broth, then adding noodles and crispy fried onions for that signature crunch.

I've perfected this recipe through years of testing, ensuring each bowl delivers restaurant-quality depth without requiring special ingredients.

The beauty of ash reshteh is its balance of simplicity and complexity. You'll start with a rich lamb broth infused with turmeric, cinnamon, and cardamom, then build layers of flavor with tender noodles and toasted onions.

While traditional recipes call for lamb, I've included a vegetarian alternative using mushrooms that maintains the same hearty texture and satisfying mouthfeel.

What makes this soup truly special is how the elements come together—warm, spiced broth meets tender noodles and crispy onions in every spoonful. The aroma alone will fill your kitchen with memories of Persian home cooking, while the combination of textures creates that perfect first bite.

The recipe scales beautifully, and leftovers actually taste better the next day as the flavors meld. Let's get started on creating this Persian classic in your own kitchen.

Ingredients for ash reshteh soup

The heart of Persian comfort—spiced lamb, toasted onions, and tender noodles in one bowl.

The lamb shanks are the star here—look for marbled cuts at your butcher or Costco for the best flavor. If you're making the vegetarian version, Portobello mushrooms (thick slices) mimic the meaty texture perfectly. For the noodles, reshteh is traditional, but any thin egg noodle works in a pinch. The spices? Penzeys or Middle Eastern markets have the best quality—if you can't find cardamom pods, ground cardamom at half the amount is fine. Toast your cumin and cinnamon in a dry pan for 30 seconds to wake up those flavors (trust me on this).

No lamb? Mushrooms or chickpeas work beautifully—just simmer them longer for texture. Running low on cardamom? A pinch of ginger adds warmth in a bind. The onions are non-negotiable for that signature crunch—yellow onions fry up best, but red adds color. For the broth, vegetable stock keeps it vegetarian, but chicken or lamb stock deepens the flavor. Pro tip: Save the onion water after frying—it's packed with flavor and adds to your broth!

This soup tastes even better the next day as the flavors meld. Store in an airtight container for up to 5 days in the fridge or 3 months frozen. The fried onions stay crispy for about 2 hours, so add them fresh when serving. Garnish with parsley and lemon wedges right before eating—brightens up the rich broth. Leftovers? Double the batch—it's the kind of soup that disappears fast.

Step-by-step instructions for ash reshteh soup

Here's how to create this rich, aromatic Persian classic with tender meat and toasted noodles.

Heat the 0.5 cup vegetable oil in a heavy pot over medium-high heat until shimmering. Pat the 1.5 lb lamb shanks completely dry with paper towels—this ensures a good sear. Working in batches if needed, add the lamb shanks and sear for 4-5 minutes per side until deeply browned and caramelized.

This step is crucial for building flavor. You want the meat to develop a rich crust that will dissolve into the broth later. If using portobello mushrooms for the vegetarian version, slice them into ½-inch thick pieces and sear for 3-4 minutes per side until golden brown. Transfer the seared meat to a plate and set aside.

In the same pot, reduce heat to medium and add the 2 whole yellow onions sliced thinly. Cook for 8-10 minutes until soft and golden brown, stirring occasionally. This caramelization adds sweet depth to the soup.

Add the 6 cloves minced garlic and cook for 30 seconds until fragrant. Then add the 1 tbsp ground cumin, 1 tsp ground turmeric, 0.5 tsp ground cinnamon, and 4 whole cardamom pods (lightly crushed). Stir for 1 minute until the spices are toasted and aromatic—this releases their full flavor potential.

Pour in the 6 cups water and bring to a boil. Add the seared lamb shanks (or portobellos), 1.5 tsp salt, and 10 whole black peppercorns (lightly crushed). Reduce heat to low and simmer uncovered for 1.5 hours for lamb or 30 minutes for mushrooms, skimming any foam that rises to the surface.

For lamb, you'll want the meat to become fork-tender and easily pull apart. If using mushrooms, they should be soft and infused with the spiced broth. The soup should develop a rich, golden color and a complex aroma from the spices.

While the soup simmers, dry the 2 oz reshteh noodles (or egg noodles) thoroughly with a clean kitchen towel. Heat a dry skillet over medium heat and toast the noodles for 2-3 minutes, stirring constantly until they turn golden brown and develop a nutty aroma. This toasting creates the signature crunchy texture.

Add the toasted noodles to the soup and simmer together for 5-7 minutes until the noodles are tender but still hold their shape. Taste and adjust seasoning with additional salt if needed. The soup should be rich, aromatic, and perfectly balanced between the spiced broth and toasted noodles.

Ladle the soup into bowls and garnish each serving with 2 whole lemon wedges and 0.25 cup chopped fresh parsley. The lemon brightens the rich flavors, while the parsley adds a fresh contrast. Serve immediately with warm crusty bread to soak up every last drop of this comforting Persian classic.

Here's the thing—this soup tastes even better the next day as the flavors deepen. Store leftovers in the refrigerator for up to 3 days and reheat gently on the stove. The toasted noodles will soften slightly but still provide that wonderful texture contrast.

Wine and beer pairings for this ash reshteh soup

White Wine Pairings

For ash reshteh soup, I recommend a crisp Persian white wine like Shirazi—its citrus notes and subtle spice complement the turmeric and cardamom beautifully. If you can't find Shirazi, try a dry Riesling from Germany, which balances the soup's richness with its bright acidity.

Serve slightly chilled to enhance the wine's crispness against the warm broth. 🍷

Red Wine Options

A light-bodied Persian red wine such as Qazvin pairs wonderfully, especially with the lamb version. For non-Persian options, a Pinot Noir from Oregon offers delicate fruit flavors that won't overpower the spices. Avoid heavy reds like Cabernet—they'll clash with the soup's delicate balance of herbs and spices.

Beer Pairings

For beer lovers, a German Helles Lager like Weihenstephaner provides a clean, malty contrast to the spiced broth. Alternatively, try a Belgian Witbier—its coriander and citrus notes mirror the cardamom and lemon in the soup. Serve the beer slightly cooler than room temperature to highlight its crispness. 🍺

Non-Alcoholic Choices

For a refreshing non-alcoholic option, serve sparkling pomegranate juice—its tartness cuts through the richness of the soup. Another great choice is Persian mint tea (sabzeh), which complements the cardamom and adds a cooling contrast. Both options enhance the soup's aromatic experience without alcohol.

Seasonal Adjustments

In summer, I like to serve ash reshteh with a lightly chilled glass of white wine or beer to refresh the palate. During winter, a warmer red wine or spiced beer enhances the soup's comforting qualities.

The key is matching the drink's temperature and body to the soup's warmth and texture.

Pro Tip for Pairings

Always taste your soup before deciding on a pairing—adjust the drink based on how rich or spicy it tastes. I often add a squeeze of lemon to the soup right before serving to brighten it up, making white wine or beer pairings even more harmonious.

The goal is balance, not competition between flavors. ✨
