• 16 ozBasmati rice, uncooked (Rinse until water runs mostly clear)
• 10.5 cupWater (For boiling rice)
• 18 gSalt (About 3 tsp fine salt for the rice water)
• 1.5 lbChicken thighs, boneless and skinless (Cut into 3–4 cm pieces)
• 16 ozFresh mushrooms (cremini or white button) (Slice 5 mm thick)
• 8.8 ozYellow onion (Thinly sliced)
• ¼ cupNeutral oil (Such as sunflower or canola)
• 1.1 ozUnsalted butter (For fragrance and richness)
• 12 gGarlic (About 4 cloves, finely grated or minced)
• 8 gFresh ginger (About 2 tsp, finely grated)
• 6 gCurry powder (About 2 tsp)
• 2 gBlack pepper (About 1 tsp, freshly ground)
• 3 tbspBrewed saffron (Made by dissolving 0.2 g saffron in 45 ml hot water)
• 4¼ ozPlain yogurt (For a golden yogurt tahdig)
• 4¼ ozBasmati rice, parboiled (Reserved from the parboiled rice)

Instructions

1. 1

   Rinse the basmati rice in several changes of cool water until the water is mostly clear, then drain well. Soak the rice in fresh water for 20 minutes to help it cook evenly and lengthen the grains.

2. 2

   Make the brewed saffron by crushing 0.2 g saffron and mixing it with 45 ml very hot water, then cover and let it steep for 10 minutes. This concentrates the aroma and gives you a vivid golden color for both the chicken and the rice.

3. 3

   Prepare piaz dagh: heat 60 ml neutral oil in a wide pan over medium heat, then add the sliced onions and stir to coat. Cook for 18–22 minutes, stirring often, until deeply golden and crisp at the edges, then transfer to a plate and reserve the oil in the pan.

4. 4

   In the same pan, raise heat to medium-high and add the chicken pieces, spreading them in one layer. Sear for 4–5 minutes, then turn and sear 3–4 minutes more until lightly browned, because browning builds depth before the saffron braise.

5. 5

   Lower heat to medium and add the garlic, ginger, curry powder, black pepper, and 8 g salt, stirring for 45–60 seconds until fragrant. Pour in 180 ml water and 30 ml of the brewed saffron, scrape up any browned bits, then cover and simmer 12–15 minutes until the chicken is just cooked through.

6. 6

   Uncover the pan and add the sliced mushrooms, tossing to coat in the saffron-curry juices. Cook 8–10 minutes until the mushrooms release their moisture and the mixture looks glossy rather than watery, then stir in two-thirds of the fried onions and reserve the rest for garnish.

7. 7

   Bring 2500 ml water to a rolling boil in a large pot and add 18 g salt. Add the soaked, drained rice and boil 6–8 minutes until the grains are tender on the outside but still slightly firm in the center, then drain in a colander and rinse quickly with 200 ml cool water to stop the cooking.

8. 8

   For an optional yogurt tahdig, mix 120 g yogurt with 30 ml neutral oil and 120 g of the parboiled rice until evenly coated. Spread this mixture across the bottom of a nonstick or well-seasoned pot to create a crisp base that releases cleanly.

9. 9

   Layer the polo: add a thin layer of rice over the tahdig (or directly into the pot if skipping tahdig), then spoon on a layer of the chicken-mushroom mixture. Repeat in 2–3 layers, finishing with rice on top, then drizzle the remaining 15 ml brewed saffron over the surface in streaks for a marbled look.

10. 10

    Dot the top with 30 g butter, then use the handle of a spoon to poke 4–5 holes down through the rice to help steam circulate. Cover the lid with a clean kitchen towel, place it on the pot, and steam over medium heat for 10 minutes to build heat, then reduce to low and steam 35 minutes until the rice is fully fluffy and aromatic.

11. 11

    Turn off the heat and let the pot rest, covered, for 10 minutes so the steam redistributes and the grains set. Fluff the rice gently, then plate by mounding the rice and spooning some chicken and mushrooms over the top, finishing with the reserved fried onions.

12. 12

    If you made tahdig, loosen the edges with a thin spatula and invert onto a plate, or lift out pieces to serve alongside. Serve the polo hot, making sure each portion gets saffron-tinted rice, mushrooms, and tender chicken for the full layered effect.
