Green Bean Casserole (Mushroom, Garlic and Bacon, Oh My!)

READY IN: 1hr 25mins
Recipe by Aussie-In-California

Every year it is my BF's and my job to bring the green bean casserole to the Thanksgiving dinner. The recipe started with us just adding bacon (because EVERYTHING is better with bacon) and then we added more "stuff" till we came up with this super fattening, garlic laden delight. Maybe next time we might have to add shredded cheese and some sauteed onions. . . food for thought :)

I have made this recipe for a couple of years now, this will be my third. Everyone loves this casserole and it is my go to dish for holidays. I use baby Portobello mushrooms and they turn out great. It is important to get the extra water out of the de-thawed green beans. I failed to do this the first time and the result, while tasted good was a little soupy. I use a salad spinner to get the water off of them.
