Prepare the Ingredients: Slice the kabocha and microwave for 2 minutes. Thinly slice the onion.
Cook the Onion: Heat oil in a frying pan over low heat. Add the onion and cook until soft.
Make the Sauce: Add the kabocha, chickpeas, flour, and the vegetable bouillon powder to the pan, then stir well to coat the vegetables evenly. Gradually pour in the milk and water while stirring to prevent lumps and cook until the sauce thickens slightly. Season with salt and pepper.
Bake: Transfer the mixture to a baking dish. Sprinkle shredded cheese evenly on top. Bake in a preheated oven at 200°C (400°F) for 10 minutes, or until the cheese is bubbly and melted.
Serve: Remove from the oven, let it cool slightly, then serve warm. Enjoy!
Notes
There's no need to peel the skin since it’s tender and edible.
For a richer flavor, add 1–2 Tbsp of cream or butter to the sauce.
