My favorite is Delicata also, I'm also a big fan of baking and freezing.......
I love to put some spices on when I bake my squash or pumpkin....some cumin and coriender, a couple of cloves of garlic (sliced) and tuck in some sprigs of rosemary or thyme. Sprinkle a little olive oil and bake til brown/slightly caramlized. It's wonderful, and it really holds up well when defrosted (doesn't get mushy).
