You can shred the squash and package 2 cups of shredded squash in zip lock bags and freeze them. Then you have pre-measured squash for squash bread and fritters, both are delicious.
Do you have a dehydrator? I wanted to make dehydrated "noodles" AKA long strips of squash for lasagna, but my zucchini is doing nothing.
For fried squash in the winter, I slice the squash, don't blanch, pack in vacuum bags and use my Foodsaver to vacuum and seal the bags. I let it thaw, cut a corner off the bag and drain the water out. Then I twist and wring the bag until I have squeezed all the water out that I can get. Open the bag, dredge the slices in cornmeal and fry.
I grew Tromboncino several years ago and that was a fun squash to grow. I used a bag of shredded Tromboncino in chili as a thickener. After the chili simmered for awhile, the squash disappeared, didn't even know it was in there.
