I like ButterNUT, (the long funny rounded oval shaped with pale orange skin)
because it keeps long time, before needing to use it right away, and it is smooth and tasty (to me, because I love any orange squash)

I steam chunks because that is the easiest to do.
But others would likely need more flavor, so either Butternut or any other type of winter squash (with orange flesh inside)
could be chopped into chunks and roasted on a pan in oven with bit of oil, to bring out more flavor, and/or sprinkled with that beloved brown sugar and butter.

Anything tastes better with butter and brown sugar on it!
One could cut a ButterCUP squash in half, (the green-skined round one with the small inner mound shape)
spoon out the inside, and bake it for a while, and when it is soft, near the end of baking, put either butter and salt and spices on it, OR put the butter and brown sugar on it. For the last 5 or 10 minutes.
I think many people would prefer ButterCup, because the flesh is drier and very flavorful, as compared to BotterNUT, which is watery and milder/less flavor.
Thin slices of squash are also good added to stir-fries, if your family likes that sort of cooking.
I never had it growing up either. I cannot imagine how I survived that.

I do love it now, and it is both tasty and nutritious.
