I am not a big squash fan, but I love this casserole. So give it a try even if you don't care for squash.
- In a saucpan over medium heat cook squash with butter, onion and sugar until tender(do not add water, it will create enough to cook).
- If excessive water in squash drain it off; let cool.
- When cooled, add egg/milk mixture and salt and pepper to taste.
- Place squash mixture in at 8x8 or similar casserole dish.
- Cover with cheese and bake at 375 degrees for 45 minutes to 1 hour.
