Directions
Preheat your oven to 180°C (350°F) and lightly grease a baking dish.
In a pan, heat a little oil and sauté the onion, garlic, and ginger until softened and fragrant. Add the Thai green curry paste and cook briefly to release its aroma.
Pour in the coconut milk and stir well. Add lime zest, lime juice, fish sauce (or soy sauce), and brown sugar. Let the sauce simmer for a few minutes to develop flavor.
Layer half of the sliced kumara in the prepared baking dish. Pour over some of the curry sauce, then add a layer of spinach or kale. Repeat with the remaining kumara and sauce.
Cover with foil and bake for about 40 minutes, or until the kumara is tender.
Remove the foil, sprinkle grated cheese on top if using, and bake uncovered for another 15–20 minutes until the top is golden and bubbling.
Let it rest slightly before serving, then garnish with fresh herbs.
