Ingredients

• Legumes:
• ½ cup dried chickpeas (or 1 (15-ounce) can, rinsed and drained)

• ½ cup dried green or brown lentils (no soaking needed)
• Fresh Herbs & Greens:
• 1 cup chopped fresh parsley
• 1 cup chopped fresh cilantro
• 1 cup chopped fresh dill
• 2 cups fresh spinach, roughly chopped
• ½ cup chopped scallions (green and white parts)
• Aromatics & Spices:
• 2 large yellow onions, one finely chopped, one thinly sliced for garnish
• 4 cloves garlic, minced
• 1 teaspoon ground turmeric
• 2 tablespoons dried mint (divided for soup and garnish)
• Noodles: 6 ounces reshteh noodles (Persian flat noodles); linguine or udon noodles can be used as a fallback
• Liquid: 8-10 cups water or low-sodium vegetable stock
• Acid: 2-3 tablespoons fresh lemon juice, to taste
• Seasoning: Salt and freshly ground black pepper, to taste
• Garnish Ingredients (Same Recipe, Still One Path):

• 1 tablespoon dried mint
• ½ cup kashk (Persian fermented whey) or thick Greek yogurt/sour cream, for topping/drizzle

Directions

1. Soak & Cook Legumes (or use the canned shortcut note)
   1. If using dried beans: The night before, place dried chickpeas and kidney beans in separate bowls, cover with plenty of cold water, and soak overnight. Drain and rinse thoroughly before cooking. Lentils do not require soaking.
   2. Cooking dried beans: In a large pot, combine the soaked chickpeas and kidney beans with enough fresh water to cover by several inches. Bring to a boil, then reduce heat and simmer gently until very soft, about 1.5-2 hours. This soup wants the beans to break down, so ensure they are tender enough to easily mash. Drain and set aside.
   3. Canned shortcut: If using canned chickpeas and kidney beans, simply rinse and drain them well. You will add them later with the lentils.
2. Build the Flavor Base
   1. In a large Dutch oven or heavy-bottomed pot, heat 2 tablespoons of oil over medium heat. Add the finely chopped onion and sauté slowly until deeply golden brown and caramelized, about 10-15 minutes. This slow sauté builds a crucial flavor foundation.
   2. Add the minced garlic, turmeric, and 1 tablespoon of dried mint. Cook for just 30-60 seconds, stirring constantly, until fragrant. Quick burn-prevention cue: Garlic and dried mint can burn quickly, so keep an eye on it!
3. Add Legumes & Simmer
   1. Add the cooked (or rinsed canned) chickpeas, kidney beans, and the unsoaked lentils to the pot. Pour in 8 cups of water or vegetable stock. Bring to a simmer, then cover and cook for about 45-60 minutes, or until the lentils are tender and the soup begins to thicken slightly.
4. Add Herbs & Greens
   1. Stir in the chopped parsley, cilantro, dill, spinach, and scallions. Continue to simmer, uncovered, for another 20-30 minutes, stirring occasionally, allowing the herbs to soften and turn the soup a beautiful "green and hearty" color.
5. Consistency Checkpoint & Thickening (No Flour)
   1. At this point, the soup should be getting thick. To achieve the desired "loose chili / porridge-like but ladleable" texture, remove about a ½ cup of beans and lentils from the pot, mash them against the side of the pot with a spoon or fork, and stir them back into the soup. Alternatively, use an immersion blender to quickly blend a small portion of the soup directly in the pot, then stir. This natural thickening method adds creaminess without flour.
6. Add Noodles (No Clumps)
   1. Break the reshteh noodles into 2-3 inch pieces and add them to the simmering soup. Stir immediately and continue to stir frequently for the first few minutes to prevent them from sticking together. Cook until the noodles are tender but still have a slight chew, about 8-10 minutes. Explain preferred texture: You want them soft but not mushy. If the soup becomes too thick, add more hot water or stock, a ½ cup at a time, until the desired consistency is reached.
7. Finish with Kashk & Lemon
   1. If using kashk (or Greek yogurt/sour cream), spoon a tablespoon or two of the hot soup into a small bowl with the kashk and stir until smooth to temper it. This prevents the kashk from curdling when added to the hot soup. Stir the tempered kashk into the soup.
   2. Stir in 2 tablespoons of fresh lemon juice. Taste and adjust salt, pepper, and lemon juice as needed. The soup should be tangy and well-seasoned. Adjust salt carefully if using kashk, as it can be quite salty.
8. Garnish and Serve
   1. For the crispy fried onions: In a small skillet, heat ¼ cup neutral oil over medium-high heat. Add the thinly sliced onion and fry, stirring occasionally, until golden brown and crispy. Remove with a slotted spoon and drain on paper towels.
   2. For the mint oil drizzle: In the same skillet with the remaining hot oil (reduce heat to low if too hot), add 1 tablespoon of dried mint. Swirl for just 10-15 seconds until fragrant. This garnish method won't burn your mint!
   3. Ladle the Ash Reshteh into bowls. Drizzle generously with kashk (or yogurt/sour cream), sprinkle with crispy fried onions, and finish with the fragrant mint oil.
   4. Suggested sides: Serve hot with fresh flatbread (like sangak or lavash), fresh herbs (like mint and basil), radishes, and Persian pickles.
