How to Make Halloween Japanese Kabocha Pumpkin Gratin

Prepare the Kabocha:
Slice the kabocha pumpkin in half, scoop out the seeds, and cut it into cubes. Steam or roast the pumpkin at 375°F for about 20-25 minutes until tender, ensuring it’s soft enough to mash.
Mash the Pumpkin:
In a large mixing bowl, add the cooked kabocha and mash it until smooth. Stir in the heavy cream, seasoning with salt and pepper to taste. The mixture should be creamy and beautifully orange.
Layer the Gratin:
Preheat your oven to 400°F. In a greased baking dish, spread half of the kabocha mixture evenly. Sprinkle a generous layer of grated cheese over the top, then add the remaining kabocha mixture.
Add the Topping:
Top the final layer with the rest of the grated cheese. If you’re using panko breadcrumbs and herbs, sprinkle them on top for a crunchy, flavorful finish.
Bake to Perfection:
Place the dish in the oven and bake for 25-30 minutes until the cheese is bubbly and golden brown. You want a nice, toasted look on top to signify it’s ready!
Serve Warm:
Once baked, remove from the oven and let it rest for a few minutes. Serve warm to enjoy its creamy texture and rich flavors—you’ll watch it disappear in no time!

Optional: Sprinkle with fresh herbs just before serving for an aromatic touch.
