To use brown jasmine rice: Increase broth to 3 cups. Bring broth to a boil before pouring over rice and vegetables. Bake for 60-70 minutes until rice is tender and all liquid has been absorbed.
I have not tested this recipe with long or short grain brown rice, but I suspect it will work similarly. I would try it with 1/4 cup additional liquid because I would prefer my casserole to be a little too moist than dry and undercooked.
My family has varying tastes for salt and pepper, so I will probably reduce those in the future and allow everyone to add as they desire. Everyone loved it though!
