Roasting: Preheat the oven to 400°F (200°C). Cut the pie pumpkin in half or into wedges and remove the seeds and fibrous center. Brush the flesh with olive oil and season with salt, pepper, and any desired herbs or spices. Place the pieces cut side down or skin side down on a baking sheet and roast for 35-50 minutes, until the flesh is tender and lightly caramelized.
Baking: Preheat the oven to 375°F (190°C). Cut the pie pumpkin in half and remove the seeds and fibrous center. Place the halves cut side down in a baking dish or on a baking sheet. Bake for 45-60 minutes, until the flesh is very tender and easily pierced with a fork. Allow it to cool slightly, then scoop out the flesh for serving, mashing, or puréeing.
Steaming: Cut the pie pumpkin into wedges or large pieces and remove the seeds. Place the pieces in a steamer basket over simmering water and steam for 20-30 minutes, until the flesh is fork-tender. Allow the pumpkin to cool slightly before removing the skin and using the flesh in soups, purées, or other dishes.
Simmering: Peel the pie pumpkin and cut the flesh into cubes. Add the cubes to soups, stews, curries, or a pot with enough broth or sauce to partially cover them. Simmer for 15-25 minutes, until the pumpkin is tender. This method allows the pumpkin to absorb the flavors of the surrounding ingredients while adding natural sweetness and a creamy texture.
Puréeing: Roast, bake, or steam the pie pumpkin until completely tender. Scoop the cooked flesh away from the skin and blend or mash until smooth. For a thicker purée, allow excess moisture to drain if necessary. Use the purée in pies, breads, muffins, soups, sauces, pancakes, or as a side dish with butter, cream, or seasonings.
