Spaghetti Squash Au Gratin Casserole

The spaghetti squash when cooked like this

reminds me of hashbrowns

I got the recipe from here

but i adapted it

 1 (16oz) pkg bulk sausage browned

1 medium spaghetti squash
1 small red onion, very thinly chopped
3/4 cup ranch dip or sour cream
1 cup shredded cheddar or mozzarella cheese

Cut the spaghetti squash in half and remove the seeds. 

Place in a covered dish with a ¼ inch of water and microwave for 10 -12 minutes.

 Using a fork, scrape the insides of the squash and transfer to a small bowl.

Mix the squash, sausage, onions, onions, sour cream and half the cheese together and mix well. Transfer the mixture to a buttered baking dish and top with remaining cheese.
Place into a 375º for 20-25 minutes. Put on broil in the last minute until golden brown on top.
