Butternut Squash Casserole

I cubed a whole butternut squash and four potatoes.  I cooked these in the microwave until soft.  Once soft, I added butter, crushed Ritz crackers, two eggs, and shredded cheese.  I mixed all the ingredients well and baked the casserole until it was bubbly.  While it was baking, I mixed butter and crushed Ritz crackers together to make a topping.  I removed the cooked casserole and added the topping evenly and baked again for about five more minutes.
