Persian Noodle Soup

Ash reshteh, the soul-warming Persian soup traditionally served for the lunar new year, Nowruz. Three beans (kidney, navy, chickpea) and lentils simmer in a golden turmeric broth until tender, then a flood of fresh dill, parsley, chives, and spinach goes in at the end for that signature deep green color.

Browning the onions first is what sets this apart from weaker versions. Three whole onions cooked down until they go sweet and caramelized build the foundation the rest of the soup leans on.

The noodles (reshteh if you can find them, linguine if not) and a tablespoon of flour thicken the broth into something spoon-coating. At the end, liquid whey or white wine vinegar adds the tang that makes ash ash.

This is three-hour soup, not quick-weeknight soup. The reward is the kind of bowl that feeds a family and tastes better the next day.

Kitchen Tips

• Soak the kidney beans, navy beans, and chickpeas overnight for faster cooking and fewer digestive issues.
• Skim the foam aggressively in the first 15 minutes of simmering the beans. Leaving it makes the broth cloudy and bitter.
• Chop the herbs at the last minute. Pre-chopped herbs bruise, oxidize, and turn the soup brown instead of bright green.
• Serve with a drizzle of kashk (fermented whey) if you can find it at a Persian market, it’s the most traditional finish.

Variations

• Top with crispy fried mint and caramelized onions (na’na dagh) for the classic restaurant presentation.
• Swap beef broth for vegetable broth to keep it fully vegetarian.
• Add a teaspoon of dried fenugreek leaves (shanbalileh) with the herbs for a more complex, traditional Iranian aroma.
