How Long Does It Take To Roast A Whole Pumpkin? - Tasting Table
Briefly

Roasting a whole pumpkin is preferable for its simplicity; simply slide it into the oven without cutting it, making it easier to access the sweet, soft flesh.
When roasting, size matters; a 3-pound pumpkin takes about an hour at 375 to 400 degrees Fahrenheit, ensuring the inner flesh reaches the desired tenderness.
Smaller pumpkins are favored for their manageability and added sweetness, making them ideal for purees, pies, and soups, enhancing autumnal flavors in dishes.
To check readiness, press the top of the pumpkin; if it's soft and a knife glides through, the flesh will be tender, ready for pumpkin dishes.
