Once your onions are slightly translucent, mix in the fresh thyme and rosemary. Pour in the broth, covering the onions thoroughly and allow to simmer gently for 25-30 minutes.
Preheat your oven to 400°F (200°C). Sprinkle the grated Parmesan generously over the top after the onions have simmered.
Transfer your pot to the preheated oven and bake for 15-20 minutes until the cheese is golden and bubbling.
Once out of the oven, let it cool slightly and serve hot as a savory side dish or a main course.
