Step 1: Prepare the Vegetable Marinade

In a large mixing bowl, combine yogurt, red chili powder, turmeric powder, coriander powder, garam masala, salt, and biryani masala. Whisk until smooth.

Step 2: Marinate the Vegetables

To the yogurt mixture, add the birista (fried onions), all the chopped vegetables (beans, carrots, peas, cauliflower, potatoes), ginger-garlic paste, and chopped mint and coriander leaves. Mix everything thoroughly to coat the vegetables well. Set aside to marinate for 15-30 minutes.

Step 3: Sauté Aromatics

Heat oil in a heavy-bottomed pot or handi. Add sliced onions and sauté until translucent. Then add cumin seeds, a bay leaf, slit green chilies, and cashews. Sauté for another minute until fragrant.

Step 4: Cook the Marinated Vegetables

Add the marinated vegetable mixture to the pot. Stir well and cook for 2-3 minutes. Add about half a cup of water, stir, cover the pot, and let the vegetables cook for 10-12 minutes until they are about 80% cooked.

Step 5: Cook the Basmati Rice

While the vegetables are cooking, prepare the rice. In a separate pot, bring 5-6 cups of water to a rolling boil. Squeeze in the juice of a lemon wedge. Add the whole spices and salt. Add the soaked and drained basmati rice. Cook for 5-6 minutes until the rice is 80% cooked. Drain the rice immediately and set aside.

Step 6: Layer the Biryani

Once the vegetables are cooked, it's time to layer. Spread half of the cooked rice evenly over the vegetable gravy in the pot. Then, add a layer of the remaining cooked vegetables (if you set some aside). Finally, spread the remaining rice as the top layer.

Step 7: Garnish and Prepare for Dum

Drizzle the saffron-infused milk over the top layer of rice. Sprinkle with more birista, a teaspoon of ghee, and a pinch of biryani masala powder for extra aroma.

Step 8: Dum Cooking

Cover the pot with a tight-fitting lid. To seal it properly, you can place a clean kitchen towel under the lid. Cook on the lowest possible heat (dum) for 10 minutes. This allows the flavors to meld and the rice to finish cooking in the steam.

Step 9: Rest and Serve

After 10 minutes, turn off the heat and let the biryani rest for another 5-10 minutes without opening the lid. Afterwards, gently fluff the biryani from the sides using a spatula or large spoon, mixing the layers slightly. Serve hot with your favorite raita.

• Adding a squeeze of lemon juice to the water while boiling rice helps keep the grains separate and white.

• Soaking basmati rice for at least 20 minutes is crucial for long, fluffy grains.

• Using birista (fried onions) in the marinade and for garnish adds a deep, sweet flavor.

• You can add other vegetables like mushrooms, bell peppers, or paneer.

• For a richer version, add a few tablespoons of cream to the vegetable marinade.
