That density means buttercup squash holds its shape well, so it won’t turn to mush when you substitute it in soups, stews, or casseroles.
 

3. The Flavor Profile Overlaps Nicely

Both squashes are naturally sweet with a subtle nutty undertone.
 
Buttercup squash tends to be a bit sweeter and richer, with a flavor some people compare to chestnuts or sweet potatoes.
