Delicata squash is exceptionally sweet. You could actually serve it for dessert, topped with some maple syrup or brown sugar and sweet spices. But it's also good as a sweet/savory side dish. Here is what I did with one last night.
1 medium delicata squash
Salt and pepper
1/2 tsp dried sage
Preheat the oven to 400 degrees.
Cut the squash in half the long way and remove the strings and seeds. Place the two halves cut side up in a baking dish. Drizzle squash with olive oil, using your fingers or a pastry brush to coat the surface. Sprinkle liberally with salt, pepper, and sage.
Add a little water to the bottom of the baking dish and loosely cover the squash with aluminum foil. Bake for 30-45 minutes, until squash is tender.
