Ash-e Jo (Persian Barley Soup)

Ash-e Jo (Persian Barley Soup)

آش جو

A nourishing, rustic soup of pearl barley, legumes, and fresh herbs—the humblest and perhaps most comforting of Persian soups. The barley lends a chewy, satisfying texture and gentle nutty flavor, while the herbs add freshness and the traditional toppings of kashk and fried mint provide the characteristic Persian finish. Simpler than ash reshteh but equally beloved, this is the soup Persian grandmothers make when you need warming from the inside out.

Cultural Note

Ash-e jo represents the ancient, pre-rice Persian cuisine when barley was a staple grain. The word 'jo' means barley in Persian. This soup is quintessential comfort food—humble, nourishing, and deeply satisfying. Unlike the more elaborate ash reshteh with its Nowruz associations, ash-e jo is everyday food, the kind of soup a Persian grandmother makes when the weather turns cold or someone needs nurturing. Its simplicity is its virtue: wholesome grains, legumes, herbs, and the essential Persian finishing touches of kashk and fried mint.

Critical Moments

  • Rinsing barley to remove excess starch
  • Cooking barley and legumes until fully tender
  • Achieving proper pottage consistency
  • Frying onions until truly crispy

PREP5 min

Soak the legumes

If using dried chickpeas and white beans, place them in separate bowls and cover with cold water by at least 8cm. Soak for at least 1 hour, preferably overnight. Rinse and drain before using.

PREP3 min

Rinse the barley

Place pearl barley in a fine-mesh strainer and rinse under cold water for 1-2 minutes, stirring with your hand. This removes excess starch and prevents the soup from becoming gluey.

Chop the herbs

Wash all herbs thoroughly. Finely chop the parsley, cilantro, chives, and dill. Roughly chop the spinach. Keep herbs together—they'll be added at the same time.

Add barley, legumes, and liquid

Add the rinsed barley, drained chickpeas, white beans (if using), and lentils to the pot. Add 2500ml water or stock. Bring to a boil, then reduce to a gentle simmer. Skim any foam that rises to the surface.

COOK55 min

Simmer until barley and legumes are tender

Simmer uncovered for 50-60 minutes until the barley is tender and the chickpeas are cooked through. Stir occasionally to prevent sticking. Add more water if needed—the soup should remain somewhat brothy at this stage. Season with salt halfway through.

Critical Step

The barley and chickpeas must be fully tender before adding herbs. Undercooked barley is unpleasantly chewy. Test by eating a few grains—they should be tender throughout with a pleasant chew.

Checkpoint: Bite a barley grain and a chickpea—both should be tender, not hard or chalky
While waiting: Prepare toppings while the soup simmers

Add the herbs

Add all the chopped herbs to the pot. Stir well to incorporate. The soup will become green. Continue simmering for 20-25 minutes, allowing the herbs to cook down and meld with the soup.

Adjust consistency and seasoning

The soup should be thick like a pottage but still spoonable—thicker than a brothy soup but not gluey. Add water to thin if needed. Taste and adjust salt generously—the soup needs assertive seasoning. Add pepper.

Serve with traditional toppings

Ladle the hot soup into wide bowls. For each bowl: drizzle kashk in a decorative swirl pattern, add a generous mound of crispy fried onions in the center, and drizzle the mint butter over everything. Serve immediately with bread.

Make Ahead

  • Soup base keeps 4-5 days refrigerated and freezes excellently for 3 months.

  • Toppings must be made fresh.

Sides

  • Fresh bread (lavash, sangak)
  • Sabzi khordan
  • Torshi
  • Raw onion wedges

Drinks

  • Doogh
  • Black tea

Substitutions

pearl barleyPot barley (whole barley) works but takes 20-30 minutes longer. Farro has similar texture. Don't use quick-cooking barley—wrong texture.
kashkGreek yogurt mixed with sour cream approximates tanginess. Can drizzle olive oil and lemon for vegan option, though flavor differs.
fresh herbsFrozen Persian herb mix works. In a pinch, use mostly parsley and spinach with some dried herbs, but fresh is much better.
chickpeasCanned chickpeas are fine—add later in cooking. Can substitute other white beans.

Scaling

Scales easily for larger batches. Barley absorbs liquid as it sits, so make extra broth or thin when reheating. This is forgiving, economical comfort food—perfect for feeding a crowd. Freezes well.
