Recently I've given priority to refining old recipes from this website. Some of my older recipes, while delicious, need new photos, new words and a refreshed perspective. I originally posted this Spaghetti Bake back in 2012 and it was in need of a makeover! I had forgotten just how yummy this casserole is and devoured it waaaay too quickly.
