This recipe will show you how to roast a whole kabocha squash in the oven to make kabocha pumpkin puree to use in many delicious pumpkin recipes such as pumpkin pie, pumpkin cupcakes, and pumpkin dog treats.
Wash the kabocha well, dry, and pierce with a paring knife all around.
Place the kabocha on a baking sheet and roast in the middle of the oven for 1.5 hours until a knife goes through easily when pierced.
Remove from the oven and cut in half with a sharp knife. Make sure to use oven mitts to handle the kabocha since it will be very hot.
Scoop out and discard the seeds, then scoop out the flesh with a large spoon. It should come out pretty easily. If not, you can roast the kabocha longer until soft.
Purée the kabocha flesh in a food processor. Add 1-2 tablespoons of water as needed to make it easier to purée.
Let cool and store in an airtight container in the refrigerator or freezer. Use in any recipe that calls for pumpkin purée.
Notes
Depending on the size of your kabocha, the roasting time may be a little shorter or longer.
To avoid handling the hot kabocha straight from the oven, you could let it cool before cutting it open.
If the flesh cannot be scooped out easily with a spoon, you may not have roasted it long enough. Simply place both halves back on the baking sheet, and back into the oven. Roast until the flesh is soft.
A 4lbs kabocha squash will yield about 4 cups of purée.
