Preheat the oven to 350°F/180°C.
In a medium-sized pan, heat 4 tablespoons of oil over medium-high heat. Add the chopped onions and cook for 6-10 minutes, stirring occasionally until golden brown.
In the baking pan, mix rice, sautéed onions, chopped herbs, the rest of the oil, and all the seasoning.
Pour in the boiling water (carefully!!) and give everything a good mix.
Cover the baking dish tightly with parchment paper, then cover it with foil to seal.
Use a paring knife or skewer to poke small holes in the foil and parchment paper.
Bake until the water is absorbed for one hour.
Adjust the oven temperature to 400°F/200°C.
Remove the foil and parchment paper and bake for 15 minutes longer until it the nice and crispy.
