Steps

Before you start

Marinate the lamb in yogurt mixture for at least 2 hours (or up to overnight) before cooking—this tenderizes the meat and builds flavor.
Soak the basmati rice in cold water for 30 minutes, then drain; this prevents sticking and keeps grains separate.
Preheat your oven to 325°F (163°C) about 30 minutes before you plan to assemble and bake the casserole.
Have all spices measured and ready; biryani cooking is sequential, so prep prevents scrambling mid-step.

1
Marinate the lamb
- In a large mixing bowl, combine the yogurt, ginger-garlic paste, green chiles (if using), 3 tablespoons (12 g) of cilantro, 2 tablespoons (6 g) of mint, ½ teaspoon cumin seeds, ½ teaspoon coriander seeds, 1 black cardamom pod (cracked), 1 green cardamom pod, one small piece of cinnamon, a pinch of nutmeg, salt, and pepper.
- Mix until smooth.
- Add the lamb cubes, toss well to coat evenly, cover, and refrigerate for at least 2 hours, preferably overnight.

Ready when: Lamb is coated thoroughly in yogurt mixture
Tip: Overnight marinating yields more tender, flavorful lamb, but 2 hours is the minimum.
2
Caramelize the onions
- Heat 3 tablespoons (45 g) of ghee in a medium saucepan over medium-high heat.
- Add the sliced onions and cook, stirring frequently, for 12–15 minutes until deep golden brown and caramelized.
- Watch carefully to avoid burning; lower heat if necessary.
- Transfer to a plate and set aside.
- Wipe out the pan but do not wash.

Ready when: Onions are deep golden brown and sweet-smelling
Tip: Caramelized onions add richness and sweetness; don't rush or skip browning them fully.
3
Toast the whole spices
- In the same saucepan (over medium heat), dry-toast the remaining ½ teaspoon cumin seeds, ½ teaspoon coriander seeds, 2 black cardamom pods, 3 green cardamom pods, remaining cinnamon pieces, 4 cloves, and the bay leaves for 1–2 minutes, stirring constantly, until fragrant.
- Do not burn.
- Pour in the water and bring to a boil.
- Season lightly with salt.

Ready when: Water boils and spices are fragrant
Tip: Toast spices for only 1–2 minutes; prolonged heat makes them bitter.
4
Cook the rice
- Add the drained basmati rice to the boiling spiced water and stir once.
- Return to a boil, then reduce heat to medium-low and simmer, uncovered, for 4–5 minutes until the rice is half-cooked (rice grains will be firm but starting to soften).
- The rice should still have a hard center.
- Drain immediately in a colander and set aside.
+ Show details− Hide details
Ready when: Rice grains are firm with soft exteriors, not fully cooked
Tip: Don't cook the rice fully; it will finish in the oven and may become mushy if overcooked now.
5
Assemble the casseroleOven 325°F / 165°C
- Preheat the oven to 325°F (163°C).
- Brush the inside of your 5- to 6-quart casserole dish with ½ tablespoon (8 g) of ghee.
- Spread one-third of the par-cooked rice evenly on the bottom.
- Layer half of the marinated lamb (with its yogurt marinade) over the rice.
- Sprinkle half of the caramelized onions over the lamb.
- Repeat: another third of rice, remaining lamb, remaining onions.
- Top with the final third of rice.
- Drizzle the remaining 1½ tablespoons (22 g) of ghee over the top, then sprinkle with remaining cilantro and mint.

Ready when: Casserole is layered and oven is preheated
Tip: Layer evenly to ensure every bite has rice, meat, and spiced onions. Don't skip the ghee between layers—it carries flavor.
6
Bake coveredOven 325°F / 165°C
- Cover the casserole tightly with aluminum foil or its lid.
- Place in the preheated 325°F (163°C) oven and bake for 45 minutes.
- The foil traps steam, cooking the rice and finishing the lamb.
- Do not open the oven during this time.
+ Show details− Hide details
Tip: Keep the cover on during the entire bake to trap steam; opening the oven releases heat and lengthens cooking time.
7
Rest and finish
- Remove the casserole from the oven (keep covered) and let it rest for 10 minutes.
- This allows the rice to fully absorb any remaining liquid and the lamb to relax.
- Carefully remove the foil (watch for hot steam), sprinkle with lemon juice, and gently fluff the rice and lamb with a fork, mixing in the caramelized onions.

Ready when: Rice is fluffy and separate, lamb is tender, and mixture is moist but not wet
Tip: Resting is crucial; it redistributes moisture and makes the finished biryani more cohesive and flavorful.

Tips

Trim excess fat from the lamb before marinating; it will render during cooking and make the dish greasy.
If you don't have ginger-garlic paste, mince 2 tablespoons fresh ginger and 4 garlic cloves very finely and combine—it's not the same texture but yields similar flavor.
For a sharper finish, add 1–2 tablespoons of fresh lemon juice just before serving, as directed; this brightens all the spices and cuts richness.
If your casserole dish doesn't have a tight-fitting lid, cover it very snugly with heavy-duty aluminum foil, pressing it down at the edges. A loose seal lets steam escape and rice won't cook through.

Make ahead

Marinate the lamb in the yogurt mixture up to 24 hours ahead; store covered in the refrigerator. Caramelize the onions up to 1 day ahead and refrigerate in an airtight container. You can also toast the whole spices and reserve them in a small bowl, uncovered, for up to 8 hours. The casserole itself is best assembled and baked fresh, though leftovers reheat beautifully.

Storage & reheating

Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat gently in a 350°F (175°C) oven, covered, for 15–20 minutes, or in a saucepan over medium-low heat with a splash of water, stirring occasionally. The biryani does not freeze well because the rice becomes dry upon thawing, but you may freeze the marinated lamb and caramelized onions separately for up to 3 months and assemble fresh when ready to bake.

Substitutions

lamb shoulder, cut into 1½-inch (4 cm) cubes, trimmed of excess fat → Goat shoulder or mutton, cut the same size. Goat is leaner and cooks faster (reduce baking time by 10 minutes); mutton is richer and needs 15 extra minutes.
ghee or clarified butter → Unsalted butter or neutral oil (vegetable, canola). Ghee adds authentic richness and nuttiness, but butter works well; use oil only if preferred for dietary reasons. Oil won't brown the onions as deeply.
basmati rice, long-grain → Jasmine rice or long-grain white rice. Basmati has a distinctive floral flavor; jasmine is similar and works well. Ordinary long-grain rice is less fragrant but still yields good results.
green cardamom pods → 2 additional black cardamom pods (omit green entirely). Black cardamom has a smokier, more intense flavor, so use sparingly. The dish will taste earthier without green cardamom's floral notes.
