Buttercup Squash with Apples, for example, is a warming winter dessert recipe made with cooking apples, brown sugar, butter, lemon juice and ground nutmeg. It is prepared by scooping out two buttercup squash halves and packing them with a mixture of chopped apples and the other ingredients prior to baking for up to 40 minutes until the squash is tender. The apples in this recipe can be substituted with chopped pears and toasted nuts can be sprinkled onto the cooked squash for added texture.
A more savory recipe is Martha Stewart's Japanese Squash and Soba Noodle Soup. This combines buttercup squash with mushrooms (shiitake, White Beeach or enoki), kombu and bonito flakes, flavored with soy sauce and served with buckwheat soba noodles. Although some of the ingredients in this dish are somewhat obscure, including kombu and bonito flakes, there are integral to the dish. They can be obtained from specialized Asian markets and supermarkets, or else online.
