Butternut Squash Soup

Well today I made the worst soup of my life. Using the squahes out of the garden I made a roasted butternut squash soup in the same way as when I make tomatoes soup, but I think I got the thickness wrong because it ended up like baby food with a bland flavour and nearly made me gag. The croutons were nice though.
Anyone got any better recipes for this vegetable as I don’t think I’ll be making soup from it again in the near future.
