Cut the pumpkin into half. Turn the cut side down and roast this at 450F about 30 minutes. Let it cool down a bit before scoop out the seeds and the flesh. I throw away the seeds and just keep the flesh.
To make delicious pumpkin soup, use a cup of chicken broth or any vegetables cube and boil it on medium heat in a pot. Stir in the roasted pumpkin flesh. Season with salt. Serve warm or cold. Adjust the chicken broth to get the right consistency.
