Clean your butternut and pat dry it
Turn on your oven to 200°C (392°F)
Using a thin sharp-edged knife or a fork, stab the butternut all over to make small holes. This will accelerate the cooking
For spicy roasted butternut, mix the rest of the ingredients in a small bowl, and apply the mixture all over the butternut squash
However, for simple roasted butternut, apply oil and salt all over.
Put the butternut to roast. After 30 mins, turn the butternut to roast the other side
If you want to incorporate the butternut squash in a stew or in a salad, don't let it cook too much. About 40 minutes are enough. This way the butternut will hold well especially in salads
For a puree, let the butternut roast for up to 1 hour. It will be tender and the skin will peel off easily
Leave the roasted butternut to cool before using it.
