Turn your instant pot to saute mode and wait for the display to turn to HOT.
Now heat 3 tbs oil or butter, once hot add in the dry spice -jeera, cardamom, cinnamon and bayleaf
Once it starts to splatter add in the sliced onion followed by the grated ginger garlic.
As the onion turns nice ad brown add the sliced veggies and saute well. I like to cut my veggies into long slices to be consistent with the log grain basamati rice
Now add the turmeric, cumin-coriander powder, biryani powder and salt. Cook veggies halfway. Add the chopped mint leaves for more flavor.
Then add the 1/2 tomato and 1/4 cup yogurt and mix well. Let the mixture cook for a bit and then add in the basmathi rice.
At this point add water for rice and also add some garam masala. Test for salt and add more if needed now.
Pressure cook the biryani in Instant pot for about 8 min in pressure mode. let it natural release and serve hot with Raita or some gravy of your choice.
