I'm going to give you a tip you will thank me for when you try it.
Roast your pumpkin first. Like chop it up, drizzle it with oil, and roast til soft. Fry some onions and add the stock and water, and add your roast pumpkin. The sweet creaminess of it is next level, I assure you!!!
Ohh thank you for that wonderful tip! I'd try it soon because I still have a half of that squash 😆
